HOUSTON DRILLERFrom the President
As sum-mer comes to an end and schools reopen, I
began writing this newsletter as Hurricane Ike barreled across the Gulf of Mexico. Being the procrastinator that I am, I failed to finish the final rendition be-fore Ike slammed into Galveston Bay and marched up through East Texas. For the next week, we along with many others suf-fered through days and nights without electricity while oth-ers went without power much longer. The day immediately following landfall, we drove up Hwy 59 to Lufkin and witnessed firsthand the devastation of fallen trees, downed power lines and smashed homes. In fact, not one light was observed burning from The Woodlands to Lufkin Texas. With the passing of the storm, oil companies and drill-ing contractors alike scrambled back into the Gulf of Mexico to survey potential damage caused by Ike. As of this writ-ing, the MMS reports that 55%
of the oil production is shut in along with 46.1% of the natural gas production in addition to 49 destroyed platforms. We in the “patch” are not new to the destruction caused by these storms having vivid memories of Hurricanes Katrina and Rita. As with any storm or hurricane, give it the respect and proper planning that it deserves.
Now, let’s get down to some chapter business! Our Septem-ber meeting was a great success providing a platform for a joint luncheon with the IADC and the AADE Houston Chapter. Over 225 combined members were present proving once again that you can “pack the house”. Jim Thompson with Marathon Oil Company delivered a dynamic and comprehensive overview on the evolution in drilling and completion in the Bakken Shale Resource play of North Dakota.
The September Luncheon was my début as President and in my haste to close timely, I failed to recognize our past President, Rusty Ritz and all his contribu-tions to the Houston Chapter.
As you are all aware, Rusty has presided over our organiza-tion for the past two years and has done an outstanding job organizing, structuring and leading our chapter. He along with other board members, steering committee members, event committee members and a host of member volunteers have worked tirelessly to trans-form the Houston Chapter into the premier organization it is today. Immediately following the luncheon, the board pre-sented Rusty with a beautiful crystal globe in appreciation for all his time and efforts.
AADE has and will continue to support educational endeav-ors at the local high school level. One such program adopt-ed by our chapter is the Milby Academy of Petroleum and E & P Technology. On August 28, 2008, the Houston Inde-pendent School District invited members from our chapter along with others to participate in a recognition award cer-emony.

Commissioner Elizabeth Jones spoke on the severe shortage of young professionals entering the oil and gas industry and the wide gap in replacements that we are currently experiencing.
On the technical side of the business, we have two splen-did groups at the forefront of drilling and completion related issues. The Deepwater and Emerging Technologies Group (DETG) tackle a wide variety of issues associated with drilling and completion operation while the Fluid Management Group (FMG) focuses on the fluid related aspects of similar opera-tions. The next meeting for the FMG is scheduled for October 22 at the WestLake Club fol-lowed by the DETG meeting on November 19 at the same site.
In regards to other Chapter business, we have Dr. Michael J. Economides scheduled to speak
at our November 6 luncheon. His topic is titled “The Domi-nance of Energy in Today’s Russia” and offers insight into Putin and the re-Sovietization of the country using energy sources as a means of national empowerment. Also, coming up shortly is the ever popular Fin-Feather-Fur-Fun Festi-val on November 13 at the Humble Civic Center. Please mark your calendars and make plans to join us at this event.”
In closing I would like to take this opportunity to thank each and every one of you selecting me to head such a splendid Chapter. Being cho-sen to represent the AADE Houston Chapter as President is a great honor and one which I accept with deep gratitude and severe conviction.

Rockit – Directional Steering Control System
A Canrig product, Rockit, addresses slide drilling prob-lems using precision pipe rotation and oscillation, im-proving drilling efficiency. Rockit is a patented software add-on to the company’s AC top drive control systems.
Applications:In slide drilling, solving the
problems of toolface setting and control are fundamental to successful projects. The system solves both these prob-lems in a manner the driller and directional driller can readily understand and use. Highly deviated wellbores produce sidewall and low side frictional forces which render slide drilling less effective than rotary drilling. This system provides a drillpipe oscillation program which reduces these frictional forces and improves the efficiency of slide drilling.
This system adds efficiency to the drilling process in reduc-ing rig flat time caused while
establishing downhole toolface settings for directional control, delivering more effective weight on bit in highly deviated direc-tional wellbores and it providing a digital method of controlling downhole toolface while drill-ing. The HMI toolface setting procedure removes the need for directional personnel to chalk drill pipe and spend time on the rotary table, working with the driller to achieve the required pipe rotation and toolface.

High-Performance Large-Diameter PDC Saves Operator More Than $1 MillionFor 16 in. and larger hole, Hughes Christensen’s Big Quan-tec™ PDC bits comprise the latest advances in PDC cutter tech-nology and bit stability to drill further and faster consistently.
PDC drilling in large-diam-eter hole is challenged by high torque and excessive vibra-tion. These problems result in shorter runs at low ROP and damaged BHA components.
This new PDC addresses these challenges with strategi-cally engineered technology.
Diamond volume manage-ment optimizes the profile and cutter position for minimal vibration. Patented EZSteer™ depth-of-cut control technol-ogy offers excellent directional control, reducing bit reactive torque to manageable levels. Patented Lateral Movement Mitigator™ delivers second-ary stability. Computational fluid dynamics maximizes hydraulic performance.
The bits are equipped with the latest high-performance application-specific cutters, appropriate for the formation.
A 26-in. high-imbalance-designed Big Quantec test bit with EZSteer technology and enhanced hardfacing—in deep-water Gulf of Mexico—drilled 1,822 ft. (~600 ft. of salt) at an

average ROP of 45.7 ft/hr. This 26-in PDC single-run footage record combined with the same bit’s first run—without repairs between the runs—saved the customer over $1.2 million.
Recently, this PDC de-sign set another 26-in PDC record, drilling 2,166 ft. (~730 ft. of salt) at 46 ft/hr.

New Spacer System Improves Displacement EfficiencyBaker Hughes Drilling Flu-ids has introduced MICRO-PRIME, a new spacer system with revolutionary technol-ogy designed to optimize the wellbore cleanup process when displacing oil and syn-thetic-based mud prior to the completion process. This new technology utilizes advanced Mesophase technology that will clean and water-wet all surfaces, even at high levels of contamination with oil and synthetic-based mud.
Displacement of the drilling or drill-in fluid to clear brine
has become a very important process in the overall wellbore completions program leading to optimized hydrocarbon recovery. Poor displacements can lead to less than planned production rates due to formation damage. Other consequences of an in efficient displacement include stuck packers, completion tool setting problems, increased rig and filtration time, increased dis-posal costs, and increased corro-sion pitting. The removal of film and solids from the well through displacement and cleanup tech-niques is essential to the suc-cessful completion of the well.
Unlike competitive systems, MICRO-PRIME is a two spacer system designed to maximize cleaning efficiency and minimize waste generation. The lead push spacer is dual function, pilot-ing the displacement and pro-viding improved cleaning and wetting capacity. The tail spacer completes the process, cleaning and water-wetting the metal. The two-spacer package allows operators to maximize wellbore cleaning efficiency while manag-ing risks associated with chal-lenging completions operations.

Smith Services Introduces Its High-Performance, Cost Effective Vertical Drilling SystemSmith Services recently in-troduced the Verti-cal Drilling System (VDS), specifically designed to solve the complex chal-lenges associated with maintaining vertical borehole trajectory. In vertical and near verti-cal drilling, crooked hole tendencies can cause abrupt wellbore angle changes, creat-ing a number of costly drilling and comple-tion problems.
The Vertical Drill-ing System (Figure 1) is designed to maintain wellbore angle and tra-jectory utilizing packed hole assembly technologies along with the latest positive dis-placement motors for opti-mized drilling performance. Proprietary BHA prediction modeling software analyzes and fine-tunes the BHA de-

sign and drilling parameters for each specific application, helping reduce project costs.
The VDS is designed with the latest, most innovative synthetic diamond protection technol-ogy on all system stabilization points for maximum gauge pro-tection and superior wellbore quality. The combination of a stiff, packed hole assem-bly/motor results in time and cost savings for the operator.
Case Study: In a recent well, the VDS
achieved an ROP increase of 40% compared to conventional packed hole assemblies used in the area. Drilling hours were reduced by 27% and bit life was increased by 154%. Wellbore inclination remained dead-on vertical with a negligible deviation of just 0.5 degrees.

Smith’s “Outlaw” PDC Bits Rede-fine Anadarko Ba-sin Performance StandardsInconsistencies drilling the vertical 7-7/8" hole section with PDC bits through Penn-sylvanian overburden to top
of Granite Wash (GW) in the Anadarko Basin was driv-ing up drilling costs. Since 2003, when operators started regularly utilizing PDCs from surface casing to top of GW, achieving consistent perfor-mance has been a problem. Issues included bit balling, lost circulation, plugged nozzles, low hydraulic energy, wellbore deviation, variations in operat-ing parameters, bit instability and abrasive wear. In many cases, 2-3 PDC bits were re-quired to reach the top of GW at approximately 11,000 ft.
Engineers set an objective of using one bit to drill-out the 9-5/8" casing shoe, then continue on to the GW at an average ROP of 50 ft/hr. Using Smith’s sophisticated IDEAS simulation modeling software, engineers developed new op-
timized bit designs that would achieve the desired results.
The comprehensive R&D ef-fort yielded the “Outlaw” PDC product line, which combines advanced cutter technology with new cutting structure designs. The bit body is de-signed to remain dynamically stable in all formations encoun-tered in the target interval.Since their recent introduction in the region, the new PDC bits (Figure 1) have set five sepa-rate county ROP records and three county footage records in the Texas Panhandle and western Oklahoma. Aver-age Outlaw ROP in the gen-eral study area is 68.3 ft/hr (13 runs), 37% faster then the target objective of 50 ft/hr.

rate of penetration, improved hole quality and more accurate wellbore placement to hot-hole environments for the first time.
When a major operator recently tapped Sperry Drilling Services to drill a high-temper-ature field appraisal campaign in the central sector of the U.K. North Sea, Sperry for the first time ran its SOLAR Geo-Pilot® XHP rotary steerable system which, combined with the SOLAR quad-combo set of logging-while-drilling (LWD) tools, successfully achieved all well objectives while increas-ing rate of penetration by 24 percent compared to offsets.
The RSS is ruggedized to withstand temperatures as high as 347°F (175°C) and pressures to 30,000 psi; with survival tem-peratures up to 392°F (200°C). Complementing it, is a suite of M/LWD sensors rated to 347°F
(175°C) and 25,000 psi. Proven in nearly 600 high-temperature runs and more than 35,000 feet of high-pressure hole last year alone, the suite provides accurate directional data in HTHP condi-tions for precise well placement, wireline-quality reservoir data while drilling and optimum log quality for effective, economic reservoir characterization.

Formation Testing And Fluid Sampling While DrillingWireline formation testers used for fluid sampling and perme-ability prediction (from pres-sure transient data) have been adopted for “formation testing while drilling” application by oil service companies. Single, dual and multi-probe tools, and oval pad and straddle packer con-figurations are available. Crucial operational questions arise. Pumping time needed for perme-ability prediction? Are there fast methods for tight zones? Time needed for clean samples? Can pump time be reduced? Focused probes? What factors control in-vasion and multiphase cleaning?
Effects of dip angle, layering, anisotropy, flowline storage and skin? Gas versus liquid pump-ing differences? Sampling while versus after drilling? Dozens of new forward and inverse mod-els addressing these issues are offered in the new book Forma-tion Testing Pressure Transient and Contamination Analysis, detailing a decade of research
and software model development sup-ported by four prestigious DOE Small Business In-novation Research awards. Numerous
calculated examples provide the “physical feel” that drillers and log analysts need to perform real-time sampling and perme-ability modeling accurately. Visit www.stratamagnetic.com for detailed Table of Contents and software offerings – book may be ordered from website.

ented microemulsion technol-ogy for the treatment of drill-ing waste in North America.
The drill cuttings cleaning system (MISTTM) is capable of washing the produced drill cuttings at the well site and enables safe disposal of the cleaned drill cuttings. Capable of keeping up with the rate of drilling, the system reduces the need for drilling waste handling and transportation and allows for the return of the recovered drilling fluid to the mud system.
The system works at ambient temperatures, uses biodegrad-able microemulsion products and, importantly, is mobile.
In addition to the treat-ment of the solid drilling waste generated, the system is equally capable of handling the liquid slop wastes resulting from all surface and down-hole cleaning operations.
With recovered oil returned to the mud system and wa-ter recovered for recycling or safe disposal, the end re-sult is a reduction in waste for disposal of 50 – 95% with reduced transportation costs and simplified logistics.
