Several sectors predict that the Thai economy will grow at a rate of 4-5 %compared with the previous year. Several policy makers also forecast that thegrowth of Thai GDP will increase at the same rate. To support the growth, theDepartment of Mineral Resources, the government organization overlooking theexploration and production of petroleum and coal which are two major contributorsto our economic growth has to ensure that we can meet the increasing demandand more indigenous energy resources be explored.
Presently, petroleum consumption in Thailand is about one million barrels of oilequivalent per day while the indigenous petroleum production is about 37% ofthe demand. With the rising oil price, it becomes a policy to reduce importedfuels to save our foreign currency while at the same time to increase indigenouspetroleum production. With large gas reserves in the Gulf, the usage of gas has beenencouraged, especially in the power generation. Natural gas vehicle project is alsopromoted. Natural gas consumption has increased 10% since the Thai economycollapsed. As a consequence, gas industry will be upgraded and might be a primeattraction for interested investors with a sign of gas industry privatization.
For the reason of energy security, Thailand needs to balance several kinds of energyused. Therefore, not only we promote petroleum and natural gas industry, but wealso encourage investment in coal business. More coal potential areas will bebidded for exploration and production. During all the processes, in order to protectthe quality of Thai’s lives and to conserve environment, greener technologicaladvances will also be promoted.
Finally, to recover from the economic crisis and for the better living of the Thaipeople, the Department of Mineral Resources, with the support and cooperationfrom the concessionaires, will do our best to supply energy fuels to supportthe expected economic growth.

The new millennium is still full of promising futures for our concessionaires. Thereare good signs for energy business, in particular, the sharp increasing oil pricesand continual energy demand despite the global economic slow down.
For the Mineral Fuels Division (MFD), in 2000, we opened 87 petroleam explorationand production areas for bids. Many areas are still open for interested oil companies.At the same time, the operations of the awarded areas are still very active,especially in the production areas. The obvious motives are the rising oil/gas pricesand the promotion of indigenous energy uses due to trade deficit from importedenergy.
Coal has also played an important role as a major energy source for decades. Manycoal basins are also open for bids in accordance with the Announcement undersection 6 bis of the Mineral Act B.E 2510 with the approval of the cabinet. Withthe new advanced technology, coal is becoming a cleaner energy and is expectedto last at least for more than 150 years.
However, petroleum and coal are unrenewable energy. To make them last longer,new resources need to be explored and wisely exploited, and energy conservationpromoted. There measures are not only aimed for recovery from present crisis butalso for the benefit of our future generations.
Finally, this annual report is prepared with the hope that it will provide usefulinformation and references on the energy activities for the readers. Much affortsare put into it. Howerer, recommendations, or correction if any, are very welcomedand we do hope the readers will find it useful.

BenefitsIn 2000 petroleum production contributed 13.474 billion baht of royalty to thecountry. This cash broke down into 58 %, 19% and 23% collected from gas,condensate and oil, respectively. The royalty increased by 59% from 1999.
In return to local community affected by production activities, portions ofthe royalty were allocated through local administrations. 20% of the royaltycollected within the produced area under several townships was equallyprorated to every Sub-District Administration Organization (SDAO). As such,30% was given to Provincial Administration Organization (PAO).
In 2000, the royalty collected from five onshore petroleum concessionswere allocated to 21 SDAOs and 7 PAOs as follows:

The aggregate cumulative petroleum royalty collected since the beginning ofpetroleum production is around 72.086 billion baht, divided into 66%, 18% and16%, from gas, condensate and oil, respectively.
To the country as a whole, the produced gas was value added by splitting offpetrochemical feedstocks. Over 2000, Thailand separated 487,500 tonnes,219,600 tonnes, 352,090 tonnes and 1,363,350 tonnes of ethane, propane, car-bondioxide and LPG, respectively, from 5 gas seperation plants. The processalso dropped 2,080,340 barrels of NGL as by-product.

Petroleum procurement of Thailandin 2000 was 1,133.24 MbpdOE, or4.0% higher than 1999. The figurebroke down into 66.5% import and33.5% indigenous production. Theincrease in import was due to naturalgas from Myanmar and the continuallygrowing domestic petroleum wasmainly because of the increase inChevron’s crude oil production.
Total import oil reduced by 3.5%, but the net importoil further reduced by 6.6%. The Middle Eastwas still major oil exporters to Thailand, but thedelivery was at decreasing rate. The Far East, especially Malaysia and Brunei, recentlybecame more important oil suppliers for Thailand. UAE, Oman, Yemen, Saudi Arabia andMalaysia were among top five of oil exporters to Thailand.
Second year in a row, Thailand received Myanmargas in much higher rate, but still lower thanDCQ. The increase of imported gas together withthe steadily growing of domestic gas made gasconsumption in 2000 highly increased by 39.2%.Large increment of gas usage was due to extremereduction of fuel oil used in electricity generation.
All items of import refined products decreasedprobably because of lower country consumption aswell as the oversupply of domestic refineries.
Shrinkage of the market caused all refineries reduced their production. All products exceptLPG decreased.
LPG production in 2000 grew by 73.3%. The total of 95.67 MbpdOE LPG production came fromoil refineries (64.9%), gas seperators (32.6%) and petrochemical plants (2.5%).
Export of the year highlighted on crude oil. About 94.5% of oil produced from Chevron’s fieldswas delivered globally. This export figure increased approximately 3.8 folds. It was quoted bysome sources that Chevron’s oil was unsuitable for refinery specification of Thai refineries.On the contrary export condensate decreased continually from 64% in 1996 down to 10% ofthe total output in 2000.

In conclusion, the energy situation in 2000 wasthat Thailand still depended on sources aboardespecially crude oil for domestic refineries.All refineries in the country would operate lessthan their capacity till next few years. Lessimportant, Myanmar gas caused the reductionof national gas production in 2000 and couldcertainly do so in the future.

ExplorationSeismic Survey
Only three seismic works were conducted in the Gulf of Thailand with a totalof 493.19 km of 2D and 134.54 sq.km of 3D. All were the acquisi-tion of Harrods Energy’s first seismic survey. By using WesternHorizon, the company completed 402.29 km of 2D seismic in B5/27(L-structure) starting from June 27 and with the same vesselproceeded to acquire 3D seismic in B2/38 (Hua Hin basin) tillJuly 18. In addition the company ran 90.9 km more of 2D seismicin B5/27 during August 12-14.
Exploration DrillingAltogether 47 exploratory and delineationwells were completed. Hydrocarbon wasfound in 29 wells, traces of hydrocarbon wasfound in 5 wells, and 13 wells were dry. Allthe successful wells were drilled by Unocal(14), Chevron (5), PTTEP (5), Harrods Energy(3), and Thai Shell (2).
Commercial oil was encountered in late 1999in the northern Gulf of Thailand concessionblocks, encouraging Unocal to put effortto further exploration. Through series of ex-ploration drilling campaign, the company proved more oil in its gas prolificbasins. Oil with gas was found in eight of all nine exploratory wells; four inYala, three in Plamuk and one in an unnamed field (10A-2). In the last quarterthe company announced the Big Oil Project to be implemented its first oilproduction in Thailand by 2001. Other six wells encountered gas, one each inTrat and West Dara, and two each in Baanpot and Funan. Of all six wells,only two were considered uneconomic.
Chevron put ten wells to delineate four fields, Benchamas, Jarmjuree,Maliwan and Kung. The outcome drew a 50% success. All two wells inBenchamas encountered either gas or oil & gas. Two of three wells in Maliwanencountered oil & gas. One of two wells in Jarmjuree proved dry and one ofthree wells in Kung was commercial. Kung-2 was identified with 120 ft of oilpay and 12 ft of gas pay in six reservoirs.
With confidence Harrods Energy drilled ten wells to delineate L-structure(Jasmine field in B5/27) in less than three months (from 23 May to 31 July2000). Almost all wells were drilled multibore by Trident XVI. Only three wellshad significant TST results. On 16 July 2000 the company plugged and aban-doned a wildcat well as a dry hole. The well is located 15 km northeast of5-1-L, an oil discovery well, drilled by Amoco in 1977. The company failedto find more gas in Chang Phuak (B11/38) with a well tested dry.

Highlight of the year focussed on the drilling campaign of PTTEP in the newlyresolved Thai-Vietnam disputed area (B15A and B16A). Back to back drillingfrom late 1999 to the first quarter of 2000 showed excellent results. All fiveexploratory wells passed through numerous gas pay formations and madethe Arthit Project 100% success. TST test of all seven wells yielded a dailyaveraged of 34.5 MMscf of gas and 882 barrels of condensate. Prior to drillingPTTEP expected potential gas reserves in the Arthit area to be in the 3-6Tcf range. The company later believed the potential to be in higher range(6-10 Tcf).
In December Thai Shellplaced two wells in S1, onefor exploration and theother for delineation. Thecompany reported NoanPluang-A01 as a gas well.The latter Nong Jig-A02proved some extent ofNong Jig oil prospect. Thediscovery of gas encour-aged the company torethink to produce oil fromthe tiny isolated pockets.
SOCO tried two more wellswithout luck. Both wellsin B8/38 were dry. For newcomers, 2000 was theyear of disappointment.Both two wildcats wereunsuccessful. One well in5441/38 (northeast ofThailand) of Forest Oilproved dry and the otherin W7/38 (the AndamanSea) of Kerr-McGee foundnothing interest.

Field DevelopmentDevelopment DrillingAs of spud date, a total of 179 development wellsand 3 water injectors were drilled in 2000, 14more than the previous year.
In order to maintain company production, Unocalplaced 115 wells on Erawan (37), Satun (25),Funan (24), Trat (12), Kaphong (8) and Jakrawan(9). All wells were successful, except two wells,Erawan E-18 and E-19, were suspended becauseof gas blow out. The company set a world recordon fastest bit run at 432 feet per hour (Erawan Q-18). Two company’s records were also set, i.e.,shortest drilling total time at 2.65 days (SatunD-27), and shortest average drilling time at 5.1days.
Chevron put another 22 wells in production forTantawan and Benchamas fields simultaneously.
Thai Shell added 20 more wells in Sirikit oilfield. Many wells were drilled to produceoil from the shallower formation, Yom.
PTTEP’s Bongkot field had 14 more production wells. The company started Phase IIIBdrilling campaign in August. As planned the minimum of 42 wells will be drilled byDecember 2002.
Sino-U.S. completed five oil wells in Bung Ya and Bung Muang fields. The higher oilprice encouraged PTTEP International to drill three more wells in U-Thong field.All wells were then put onto production.
During the year, many exciting and interesting incidents happened several times.The most exiting incident in the Gulf was the gas blow out of well Erawan E-18 andE-19 while drilling to the depth of 1,012 and 1,022 feet, respectively. Fortunately,no one was injured.
The Drill-In Casing system, firstly introduced by Unocal in late 1999, was widelyaccepted and utilized by many operators. This technique was relevant to time andcost saving slim-hole drilling. Technically, well spudded with 9 5/8 inches casing,narrower than conventional one and penetrated through soft formation about1,500 feet depth. On October 5-7, PTTEP had emergency shut down of Bongkotproduction due to a rupture of the flexible line joining between a calm buoy andFSO. Moreover, about 25 cubic meters of condensate were spilled out.
Thai Shell, the onshore major oil producer, was exploring for more gas in the Sirikitoilfield to meet demand of the EGAT’s power plant extension in the near future.

Production Licensed Area (PLA)
Five PLAs, East Dara, West Dara, Funan J,Funan B&H and Funan K, were awarded toUnocal.
On 28 December 1999, Chevron announcedits success in discovering a new field.Following assessment led to the discovery ofpotentially significant petroleum reserve.To develop the field, the company subse-quently applied for the North Jarmjuree PLA
and then was finally approved on November 2. The PLA, covering 503.2 squarekilometer was granted for 20 years duration. In November the plan to putthe new field on-stream was endorsed by Thai government. This developmentwas expected to cost US$ 200 million at least, including eight offshoreplatforms and 60 production wells. Production from the field was scheduledto start on early 2003 with an initial gas rate of 50 MMscfd, ramping up to190 MMscfd and 6,000 bod in 2005.
Harrods submitted PLA application for Bussabong gas field and PTTEP alsoapplied for Ton Sak field.
Production EnhancementThai Shell was studying a “Water-Flood” system. This high technologyapproach was aimed to maintain its rate at 25,000 bod from the Sirikit oilfieldfor ten years. The new system was expected to be in place in either 2004or 2005.Chevron also launched the Waterflood Project in November to enhance oilrecovery of Benchamas field. As planned, the project will last for ten yearsand firstly started with three injector wells this year.
LogisticsPTTEP replaced Bongkot FSO (Floating, Storage and Offloading) with a tempo-rary one. The 3-months fast-track project, valued at US$ 20 millions, began inSeptember. The replacement was due to serious corrosion in Bongkot FSOûsballast tanks and needed to be dry-docking at Unithaiûs shipyard in Chonburi.The FSO was less than eight years in service for PTTEP at 600 MMscfd and13,000 bcd from Bongkot field. The company was making considerationbetween FSO and CSST (Concrete Subsea Storage Tanker) for the new perma-nent storage.
New PlatformsIn August, Chevron was pre-qualifying for an expected tender to fabricatenine wellhead platforms. Infield pipelines for connecting the platforms weretendered separately. All platforms would be installed in Maliwan, Benchamasand Tantawan fields early 2001.

In September, two more wellhead platforms and additional 15 miles pipelineswere installed by Unocal. The company earlier on July 7 announced “UCUAlliance”, the construction group formed by Unocal, Ltd., Clough ThailandCo., Ltd., and Unithai Shipyard and Engineering Ltd. The alliance woulddesign, procure, fabricate, and install wellhead platforms and submarinepipelines. The move could perhaps save the company by 10-15% in wellheadplatform and pipeline cost.Started in September 1999,the phase 3B of the BongkotField Development was inprogress. The 670 dayslong project targetted toinstall two new more well-head platforms, WP11 andWP12, and lay 22.5 kmlong of 16-inch sealine.The schedule to completethe project was for WP11on 1 April 2001 (19 months)and WP12 on 1 June 2001(21 months).
Big Oil ProjectOn October 19, Unocalsubmitted an applicationfor commercial crude oildevelopment for the firsttime in the Gulf of Thailand.The earlier exploration inblocks 10 and 11, north ofthe Erawan gas field disclosed evidence of an economic volume of crude oil.Around 15,000 bod was expected to be ready for production within 8-10months from Plamuk, Kaphong, Yala, and Surat fields. The company plannedto install a new oil-processing platform, and a crude oil storage tanker. Forthe entire project, ten platforms would be installed. The cost of developingthese oilfields was expected to be about US$ 270 million over the nextsix years.

And, its first Tcf of sale gas from Bongkot wasreported in December [since the first production starting on July 10,1993].According to Unocal Fact Sheet issued in July, the company reached thefourth Tcf (sale gas) on May 24. Even as a new comer, Chevron alreadyovertook Thai Shell position as the largest oil producer since February.The company rapidly accelerated its production from Benchamas field andset a maximum rate of 36,266 bod on July 29 and 150.5 MMscfd onNovember 11. In contrary, the company slowed down its Tantawan production,leaving peaks at 12,908 bod on January 15 and 69 MMscfd on January 26.
History ProfileSince the first Erawan gas field has been put on production in 1981, Thailandhas newly additional producing fields almost every year. Until 2000 year-endat least 27 petroleum fields are or used to be petroleum producers. As for salevolume, the production by concessionaires began at 0.409 MMbbl of liquidpetroleum and 10.038 Bcf of gas in the first year. The figures launched to36.539 MMbbl and 671.703 Bcf in 2000.

Behind the PipeIn 2000 gas production nationwideamounted to 713.128 Bcf. Comparedto sale volume a loss was 41.425 Bcfor about 5.8 % of total output. Asreported the loss was caused mainly byfuel and flare. But for Thai Shell, mainportion was transformed to LPG. Incontrary, much reduction from UnocalûsPailin gas was owing to CO2 removal.However, tens Bcf of flare gas wasspeculated. To conserve this valuable itis nessessary to minimize the disposalas much as possible.

Similar toelsewhere, Thai crude oil wassold out and half of them wasshipped abroad. The same casehappened to condensate; about1.9 MMbbl was withdrawn fromstorage and almost emptiedthe tanks.
Export Liquid PetroleumThailand is a net petroleumimport country. But portionsof produced petroleum havebeen exported every year. In2000 about 11 MMbbl of crudeoil and 3.2 MMbbl of condensatewere shipped out. Thai con-densate has been sent out atdecreasing rate since 1996, butexport of crude oil expandedrapidly. The export quantity ofoil was equivalent to 96.5% ofChevronûs sale oil, or 57.7% ofthe countryûs production. It isessential that more oil is usedomestically.

In comply with environmental protection DMR initiated three projects tomonitor adverse impact induced by production in the Gulf of Thailand.First project aims at assessing whether or not mercury dispersion from gasproduction affects surrounding living things. The study was done throughfinding mercury anormaly in produced water. The project conducted byChula Unisearch and the Aquatic Resources Research Institute, ChulalongkornUniversity was focuses on amount of mercury accumulation in tissue of fishliving around Erawan, Satun, Platong, Funan, Bongkot and Pailin productionplatforms. The project is to complete the first half period of one-yearcontract in January 2001.
Second one studies on “Baseline Environment Database for PetroleumExploration and Production Industry” and can be separated into three phases.Work done in Phase I starting from September 2000 covered a review andconstruction of Pro-Forma EIA reports on standard seismic and drillingactivities, a review of past EIA submissions, a development of an EIA databasein an electronic format and an immediate term training. The project wasscheduled to complete at the end of February 2001.
Last but not least, the project started from the last quarter of 2000 on heavymetal problem arising from gas production. The study is to determinemercury, arsenic and cadmiun content in petroleum and water produced byUnocal, PTTEP and Chevron.
All these moves could make all concerning persons clearly understood andwill do next the best for the ecology.

A c t i v i t i e s i n t h eMalaysia - Thailand Joint Development Area (MTJDA)
(MTJDA)Cakerawala Gas Field Development Projects
Since Gas Sales Agreement (GSA) for the supply of gas from Block A-18 of theMalaysia-Thailand Joint Development Area was signed on October 30, 1999,the development of Block A-18 has been carried out.
Cakerawala gas field , located in Block A-18, will be the first field developedin the Malaysia-Thailand Joint Development Area (MTJDA). The contractors ofthis block are Petronas Carigali (JDA) Sdn. Bhd., Triton Oil Company ofThailand (JDA) Limited and Triton Oil Company of Thailand Inc.,the operatoris Carigali-Triton Operating Company (CTOC).
On January 22, 2000, a consortium ofTechnip Geoproduction. Sdn.Bhd.,Samsung and Saipem was awarded anEngineering, Procurement, and Con-struction (EPC) contract by CTOC toconstruct and install Cakerawalafacilities in order to deliver gas at 390MMscfd to joint buyers, PTT andPETRONAS by July 2002. The Cake-rawala Gas Field Development Projectwill consist of Central ProcessingFacilities (CPF), a riser platform,three wellhead platforms, A, B and C,and Floating Storage Unit (FSU).
The CPF is a fully integrated facilitiesthat consist of two trains of gas processing facilities, utilities, accommodationand a cantilever flare. Gas processing also equipps CO2 removal and associatedpretreatment equipments to remove CO2 down to 15% before delivering to thejoint buyers.
The riser platform is a platform that gathers the incoming and outgoingpipelines. A sale gas compressors is also installed on the top deck of the riserplatform.
The three wellhead platforms are designed to accommodate 35 developmentwells which are expected to be drilled in this field. The first well commencethe drilling in August 2001.
The FSU is utilized to store the stabilized condensate with a capacity of500,000 barrels and also to offload the stored condensate by means of shuttletanker as charter by customer.
The total contract value of the EPC project is US$ 578 million. As of December31, 2000, the progress of the project is about 45%.

Petroleum ReservesProved petroleum reserves as of December 31, 2000 compared to those ofthe previous year are:
1999 2000 +/-
Natural Gas (Bcf) 12,168.00 12,704.83 +4.4%Condensate (MMbbl) 212.68 243.67 +14.6%Crude Oil (MMbbl) 156.18 272.02 +74.2%
Gulf of ThailandProved natural gas reserve goes up moderately while condensate and crudeoil reserves rise significantly over those of last year. Major contributions tothe increase of oil and condensate reserves are Big Oil project of Unocalwhich consists of Surat, Yala, Plamuk and Kaphong fields, Benchamas fieldwaterflood project which started in the late 2000 with promising results, anda newly delineated project; Kung. In Malaysia-Thailand Joint DevelopmentArea (MTJDA) oil reserves are assessed separately for the first time asexploration results confirm the presence of crude oil. Major contributions tothe increase of gas and condensate reserves are new exploration wells anddelineation wells of Bongkot and Arthit projects as well as higher condensategas ratio used in MTJDA.
OnshoreAlthough onshore natural gas reserve declines moderately, total natural gasreserve still rises due to a positive contribution from the gulf, which hostsover 90% of natural gas reserve. Sirikit oilfield is the only onshore field thathas delineation activities and resulted in the transfer from possible andprobable oil reserves to proved oil reserve. Oil reserve of other onshore fieldscontinues to decline. Cumulative production and reserves of Fang project wasrevised with cooperation of Department of Energy Defense (DED) resultingin obviously higher numbers of cumulative production and reserves than ournumbers posted last year.

Coal Activities in ThailandOverview
For a century, Thailand has experienced in utilizing coal. Initially used assteam raiser for locomotive, coal has been used later as a main fuel inelectricity generation for decades. Even in 1999 coal ranked third after natu-ral gas and fuel oil in Gwh production. After participation of private minerssince early 80s, coal becomes more and more important for cement manufac-turing. Higher tonnage of coal burnt in cement furnace set the record everyyear until 1998 when economic crisis emerged. Exploration history indicatedthat the majority of coals found in Thailand are low calorific, lignitic andsub bituminous coal.In the new millennium, coal will still be a future fuel for Thailand, not onlybecause of plenty available, but cheaply in cost. Even blames on its environ-mental adverse quality but with innovated technology dirty coal can be usedfriendly and safely plausible.
Mining LeasesAccording to mineral laws, to explore and exploit coal in Thailand are underregulated and supervised by DMR. Exploration license for particular blocks willbe awarded to interested prospectors. Shortly after fully investigation theycan apply for their known reserves. At least a minimal area of 300 rais (120acres) per mining tract will be awarded if no objection from EPA. Until 2000 year-end, there are altogether 27 coal concessionaires holding 140coal tracts throughout Thailand. Most are located in the northern provinces ofthe country i.e. Lampang, Lamphun, Chiang Mai, Phayao and Tak. Currently,there are 14 coalmines on the list, but only ten still on production. Eight ofwhich are in northern Thailand and one each in the central and southernregions.

Production ReductionAs reported, coal mining in Thailand has started since 1955 at Mae Moh. Coaloutput steadily increased every year till 1978. The mining rate afterwards wassteeply climbing as long as Thai economy expansion. The peak production wasset at 22.133 million tonnes annually in 1997. In 2000 Thailand produced only17.7 million tonnes of coal, the third year in a row of reduction (by 3% lessthan of 1999 output).By basin, coal produced in 2000 fell into 76.94% Mae Moh, 10.37% Li, 9.22%Mae Than, 1.06% Chiang Muan, 0.61% Bo Luang, 0.56% Na Hong, 0.52% NongYa Plong, 0.47% Krabi and 0.03% Mae Teep. Monthly output of coal variedbetween 1.2-1.7 million tonnes depending upon market demand rather thanclimatic adverse. Wet months in Thailand are from June to September.The value of coal produced in this year evaluated by posted price for collect-ing royalty is 8,850 million baht and the collected royalty is 335.98 millionbaht. Four per cent of royalty is applied to 500 baht posted price of coalannounced by DMR.
Imported CoalDue to lower calorificvalue of domestic coal,higher calorific coal fromoutside is thus necessarilyimported every year. Evenin economic depressionyear Thailand still broughtin coal in growing value.Of the total, bituminouscoal for cement manu-facturing was highest.
Coal PriceIn general coal price in Thailand is restricted mainly to heating content. Themost acceptable heating value is standing at 5,000 kcal/kg. At presentdomestic coal is purchased 500 baht/tonne at mine mouth. Coal buyer willpay bonus for additional heating content. In contrast, coal seller must paypenalty in case of outer limit of ash and sulphur content. Transportation costof domestic coal mostly sent from northern Thailand to Saraburi, the cementindustry center is estimated about 340 baht/tonne.For coal import, both long-term contract and spot-lot is applicable. Long-termcontract provides quality reliability and supply security. Referring to JBP(Japanese benchmark price) the cost can be as high as 28.75 US$/tonne for6700 kcal/kg coal at loading point. Mostly used for Thailand, the spot-lotis advantageous in demand fluctuation but weakly versus JBP. High calorificcoal (6400-6600 kcal/kg) costs about 30 US$/ tonne and 22 US$/ tonne formedium calorific one (6000 kcal/kg) at discharge port.
Coal UtilizationThailand’s coal utilization in 2000 was 13.5% of overall fuels consumption.The utilized coal totalled 17.642 million tonnes. The largest fraction, 14.13million tonnes or 80.12% was used for EGAT’s Mae Moh power plants. The restof coal was utilized in other industries such as cement, tobacco, lime, foodand etc. Utilization of coal in Thailand has decreased since 1999 because ofeconomic crisis. However, it is foreseen to rise again in 2005.

CEPûs Activities in 2000Five additional areas were explored and assessed as follows:To prove coal existing in Mae Sai basin of Chiang Rai province, 11 wells werepreliminarily drilled, but no coal was found. Geological mapping of 550 Km2
was also conducted in the year.
To search more coal in Mae Ramat basin of Tak province; 19 follow-up wellswere drilled. Several coal seams of 1-285 cm in thick were encounteredbetween 172-294 m deep. Analysis of 114 coal samples showed its represent-ed quality as following: 3,284 cal/g heating value, 10.50% moisture, 39.70%ash and 7.03% sulfur. This effort added up the basin resource to 37.54 and72.17 million tonnes of measured and demonstrated resources, respectively.
Seven exploratory wells were drilled to a cumulative depth of 1,738 m in NaSai sub-basin within Li basin of Lamphun province. The drilling found coalseams of varied thickness of 1-27 cm at depth of 172-294 m. On the averageof 20 samples the coal contains 2,915 cal/g heating value, 29.47% moisture,22.28% ash and 5.40% sulfur. The amount of 1.31 million tonnes of measuredresource and 5.27 million tonnes of demonstrated resource were computed.As for the better know of vertical information the lateral extant covering 100Km2 of the area was also investigated and mapped.
Five more exploratory wells were drilled with an aggregate depth of 641 min Phob Phra basin of Tak province, but no coal found more in the area.
Only 11 seismic lines of 85 Km were conducted over Mae Jai basin of Phayaoprovince. The result of the survey will be determined for future drilling.

Coal BiddingAccording to SEC 6 bis of Mineral Act (1967), 13 areas have been confined fora special study of coal by DMR solely and no one was permitted for coal tractsin the areas. For many years at work DMR found coal potential in severalbasins such as Mae tha, Serm Ngam and Wang Nua. In 2000 the preparation ofthe areas selection with relevant documents was carried out. Announcementof Ministry of Industry for bidding was as well under drafting. The departmentplanned to open bidding in 2001 for interested private sector to exploit thosecoal.

Joint ProjectDMR incorporation with JICA (the Japan International Cooperation Agency)studied coal within 63 square kilometers in the northern part of Ngao basin,Lampang province. The study targeted in three main objectives:1. Comprehensive analysis of the coal seam condition and estimation of the
mineable reserve.2. Conceptual planning of mine development with an upgrading technology
for improvement in coal quality.3. Technology transfer on coal mine development procedures i.e. exploration,
evaluation, mining, environment protection, coal quality improvement, etc.
Clean Coal Technology (CCT)CCT is the best ever way to use coal safely and efficiently. Through this meanmany air pollutants directly emitted from previous conventional coal combus-tion can be reduced effectively.
Since 1995, DMR had applied CCT in various means in order to see how betterto utilize domestic coal. The study concluded as follows :
A laboratory testing using coals from Wiang Haeng and Sin Pun fields for coal-water fuel preparation and gasification was conducted. The project resultedin finding satisfactory reduction of equilibrium moisture content and remark-able escalation of energy density. The fuel burnt fairly well.
In order to study for coal liquidmixture technology, high ashcoal of Ngao field was foundsignificant preferences such ashigh reactivity, low porosity, lowchlorine, and presence of inher-ent Fe/S, the catalytic material.
But more suitable was Mae Ramat coal due to lower moisture, ash, oxygen, sulfur andexchangeable calcium than Ngao coal. Used as a liquefaction feedstock, Mae Ramatcoal could yield commercial oil and reduce some operating problems.
A preliminary economic evaluation of underground coal gasification was carried outfor Sin Pun lignite. The coal contained on average 17.5% moisture (as received),10.8% ash (air-dried) and 11.4% sulfur (air-dried). Because of its high reactivity,attributed to the high levels of acid-extractable Fe and Ca, the coal was recom-mended for in situ gasification. Further studies for locally uses of the coal gasproceeded in Li and Chiang Muan basins. The first one could produce gas enoughfor local industries only. But the latter tended to supply sufficiently both forindustries and power plant. An economic evaluation of the energy productioncosted only 0.87 baht/kWh.
Coking potential was experimented to Thai coals from various places, Wiang Haeng,Ngao, Mae Ramat, Sin Pun. No one had coking property even blended with cokingcoal. However, for cleaner used and easier transported, these coals could be formedbriquette. Further studies carried over Chiang Muan, Li, Mae Than and Nong Ya Plongcoals. Preliminary conclusion suggested those formed-coke gave off heat almostthe same as real coke eventhough weaker in other properties i.e. strength, density,sulfur and ash contents. To replace Japanese or Chinese coke in industrial uses,the formed-coke need to be further up-graded
