In accordance with 30 CFR 250.34, as amended, Mark Producing, inc., herein respectfully submits for approval a proposed Plan of Exploration for the referenced block.

Leases OCS-G 7755 and OCS-G 7756, effective August 1, 1985, were purchased by Mark 100%. Previous activities on these leases consist only of preliminary activities that did not result in any physical penetration of the seabed.

Mark Producing, Inc., submits eleven (11) copies of tht. proposed Plan of Exploration. Five (5) copies are considered "Proprietary Information" and are exempt from disclosure. Six (6) copies are "Public Information", ine information believed to be exempt is geological and/or geophysical. As operator of this lease, Mark requests that thb information and data considered exempt be dispersed for use only by the U. S. Government.

Three (3) copies of the High Resolution Geophysical Survey Report for thb lease were submitted to your office on January 24, 1986.

We anticipate drilling on thb lease to begin on or around June 1, 1986.

If there are any questions, please call.

Sincerely,

1. DESCRIPTION OF PROPOSED ACTION

Mark Producing, Inc. plans to conduct exploration activities on Ship Shoal Block 203

and 220 (OCS-G 7755 and OCS-G 7756).

As proposed, the Plan of Exploration for Ship Shoal Blocks 203 and 220 consists of

drilling ten (10) wells.

A this time, planned commencement date for Well "A" and all associated activities

in the above blocks will begin on or about May I , 1986.

(a) TRAVEL MODES. ROUTES AND FREQUENCY

The proposed exploration activity for iederal leases OCS-G 7755 and

OCS-G 7756 will require the use of a jack-up rig to drill the exploratory

wells. The rig will be moved to Ship Shoal Blocks 203 and 220 from an

unknown location in the Gulf of Mexico.

In addition to the drilling rig, service boats will be used to transport

equipment, material, personnel and supplies to the drill sites. It is estimated

that the crew boat and supply boat will make daily round trips to the rig from

support bases located in Morgan City, Louisiana. The proposed travel route for

these vessels begins at Morgan City, Louisiana, and will move to Blocks 203

and 220 via the most direct route from Morgan City, Louisiana.

Helicopter flights to Ship Shoal Blocks 203 and 220 will average 10.5

round trips per week and will originate from and return to Morgan City,

Louisiana. The helicopters will normally take the most direct route of travel

between the two points when air traffic and weather conditions permit.

(b) SUPPORT BASE

The proposed activities will utilize a support base at Morgan City,

- 1 -

Louisiana. The base provides 24-hour service, a radio tower with phone patch,

deck space, offlce space, a parking lot, equipment and supply storage space,

drinking and drill water, etc. These proposed exploration activities will help to

maintain tnis base at its present levels of activity. No expansion of the

physical facilities or the creation of new jobs is expected to result from the

work planned in conjunction with Blocks 203 and 220.

(c) NEW SUPPORT FACILITIES

No new onshore support facilities such as new land bases, refineries,

storage facilities, pumping stations, boat docks, helicopter pads or fueling

facilities are likely to be required because of the activities planned for Blocks

203 and 220. Any newly discovered deposits of hydrocarbons should help to

maintain onshore facilities and activities at or near their present levels rather

than result in some type of expansion.

(d) NEW TECHNIQUES OR UNUSUAL TECHNOLOGY

No new techniques or unusual technology will be required for this

operation.

(e) MAPS OF PROPOSED ACTIVITY

As shown by the attached Vicinity Plat, the proposed activity is located

70 miles south from tho Louisiana shore.

(f) TRANSPORTATION OF OIL AND/OR GAS

If producible hydrocarbons are found they are likely to be transported to

shore through connections with the pipelines already in place near Blocks 203

and 220.

2. DESCRIPTION OF THE AFFECTED ENVIRONMENT

<a) PHYSICAL AND ENVIRONMENTAL

- 2 -

(1) Commercial Fishing

Ship Shoal Blocks 203 and 220 are located approximately 70 miles

from shore where the water depth is approximately 120 feet. Shrimp and

menhaden are the primary fishing resources found in this area.

The placement of a drilling rig on each Block will remove a portion

of the seafloor and waters above from harvesting by commercial

fisher es. Additionally, the waters adjacent to the drill sites may

become temporarily turbid due to drilling operations. These operations

should have no significant impact on commercial fisheries.

(2) Shipping

Ship Shoal Blocks 203 and 220 are clear of all fairways and

anchorage areas. Operations in this area will be in accordance with the

U.S. Coast Guard's regulations regarding navigation standards. There

should be little or no impact on shipping resulting from the proposed

operations.

(3) Recreation

The proposed activities, which are primarily confined to Ship Shoal

Blocks 203 and 220 are located approximately 70 miles south of the

Louisiana coast lin<.. Along the coastal waters of the Gulf of Mexico off

Terrebonne Parish, Louisiana, are located coastal beaches and ports

supporting pleasure boating and sport fishing. To protect these

recreational resources, Mark Producing, inc. will comply with OCS Order

No. 7 regarding pollution prevention and control, and has established an

Oil Spill Contingency Plan which was approved by the Minerals

Management Service. There are no adverse impacts expected as a result

of the proposed activities.

- 3 -

(4) Cultural Resources

Ship Shoal Blocks 203 and 220 lie Inside the Cultural Resource

Sensitivity Demarcation Line (USDI, 1979, Visual 1) and, therefore, falls

in an area where cultural resources are likely to be found. An

archeological survey was required for Ship Shoal Block} 203 and 220.

Mark Producing, Inc. agrees that if any site, structure, or object of

historical or archeological significance should bo discovered durirr

operations, the findings will be immediately reported to the Sups:

ami every reasonable effort will be made to preserve and prc-tdoi t*ie

cultural resource from damage until the Supervisor has g-

as to its preservation.

(5) Ecologically Sensitive Features

There are no known ecologically sensitive features located on Ship

Shoal Blocks 203 and 220. The closest sensitive feature is located along

the coastal shores of Terrebonne Parish, Louisiana. The sensitive

features include the primary fish and shellfish nursery grounds, and the

recreational beaches.

With exception to the minimal boat and helicopter traffic, all

operations will be restricted to Ship Shoal Blocks 203 and 220. The

proposed activity will have no effect on any ecologically sensitive

features.

(6) Existing Pipelines and Cables

Texas Pipeline Company has a 20" oil line (OCS-G 3303) which

crosses the east line of Block 203 approximately 6700* from rhe northeast

corner and crosses the south line of Block 203 approximately 7100' from

the southeast comer. This same pipeline crosses the north line of Block

- 4 -

220 approximately 7100' from the northwest ou ., ••• anJ crosses the west

Une of Block 220 approximately '0* from the southwest corner.

(7) Other Mineral Uses

The activities proposed for Ship Shoal Blocks 203 and 220 will have

no direct or indirect impact on other mi -al uses.

(8) Ocean Dumping

Ocean dumping is prohibited in this area.

(9) Endangered or Threatened Species

Msrk Producing, Inc.'s proposed operations at Snip Shoal Blocks 203

and 220 are located approximately 70 miles south of the Louisiana

coastline off Terrebonne Parish, Louisiana, n<«.••><• coastal chores and

upland areas are the habitat of several endangeruo or threatened

species. These species include the Arctic peregrine falcon, the red-

eockaded woodpecker, the bald eagle, the American Alligator, the red

wolf, Kemp's ridley sea turtle. These species may be affected by the

development of coastal lands and/or the occurrence of oil spills which

may affect the species directly cr through their food sources. Since the

proposed activities include no plans for the development of coastal lands,

the impact on endangered or threatened species is primarily based on the

occurrence of oil spills.

On pages III-5 through DJ-72 of the Final Environmental Impact

Statement for OCS Sale No. 47 there is a disenssi- .i of the factors for

estimating the significance of oil spills and their impacts. The impacts

on various endangered and threatened species will depend on the natuir

ot the spill, weather conditions, proximity of spill to species, tolerance

for oil of species, and the response time and effectiveness of the oil spill

cleanup and containment services. Given these variables, the impact on

- 5-

the various endangered and threatened species will vary from little or no

effect to serious.

The expsi'ience of oil and gas exploration in the Gulf of Mexico

indicates that there is a small probability of occurrence of an oil spill.

The Draft Environmental Impact Statement (DEIS) for OCS Sale No. A-

62 and 62 indicates on page 71 that the naggregrate 15 year spill rate is

.0009 percent of the total volume produced." Table 7, page 73, of the

DEIS indicated that there have been only 30 incidents of oil spills for this

15 year period. The probability remains low because of the level of

technology used by the oil and gas industry to insure safe and responsible

operations. Mark Producing, Inc. as a prudent operator will take the

necessary measures to reduce the probability of oil spills. Mark

Producing, Inc.'s proposed operations at Ship Shoal Blocks 203 and 220

should pose no threat to any endangered or threatened species,

(b) SOCIO-ECONOMIC

(1) Related New Employment

Not applicable at this time.

3. UNAVOIDABLE ADVERSE IMPACTS

The proposed drilling activity in Ship Shoal Blocks 203 and 220 will result in

the discharge of drilling mud and cuttings into the waters of the Gulf. The discharge

of rYill cuttings will bury sessile benthic organisms in local areas under the

discharge. The disposal of mud may result in a minor decrease in primary

productivity due to the mortality or functional impairment of phytoplankton and

algae in area of high turbidity. A large oil spill is very unlikely but could result in

localized severe mortalities, and severe selective and functional impairment of

- 6 -

phytoplankton communities, thereby altering the community structure for an

unknown period of time. These impacts are considered temporary and minor.

Air emissions from combustion of diesel fuel in rig engines, boat engines and

helicopters can affect the air quality near the mobile offshore jackup drilling rig and

near the onshore travel routes. In most cases, these emissions will be local in nature

and will be quickly dissipated by climatic conditions. Highly volatile, low molecular

weight hydrocarbons would be released into the atmosphere from a blowout with

release of natural gas. These hydrocarbons would undergo some unknown degree of

degradation, possibly resulting in photochemical smog. If a blowout resulted in a

fire, large amounts of particulate carbon and oxides of carbon, along with smaller

but unkown amounts of sulphur oxides, volatile hydrocarbons and partially oxidized

compounds would enter the air. Local air would be severely degraded for the

duration of the fire. The extent of degradation is indeterminate, but it is unlikely

that it would be high enough to affect land resources or human health.

These exploratory activities are not expected to harmfully affect water

quality cr interfere with commercial fishing operations, recreational activities or

shipping traffic.
