U.S. DRILLING TO RISE UNLESS OIL PRICES SLUMP

Jan 28, 1991 G. Alan Petzet Exploration Editor U.S. well completions will post a strong increase in 1991 unless oil prices drop sharply. Gas drilling supported by federal tax credits will remain active in 1991. But the high crude oil prices that revived shallow oil drilling in second half 1990 may not persist. Oil & Gas Journal's latest estimate is that the industry drilled more wells in 1990 than either the 31,700 estimated in January 1990 or the 34,320 forecast in July 1990.

PLANS ADVANCE FOR U.S. GAS PIPELINE PROJECTS

Jan 28, 1991 Three proposed U.S. pipeline expansions have passed federal regulatory milestones in efforts to move a combined 3 bcfd of gas to West Coast markets. Here is a progress report:

ARKLA EXPLORATION TO DRILL TIGHT SANDS IN EAST TEXAS

Feb 4, 1991 Directors of Arkla Exploration Co., Shreveport, have approved an 80 well, $90 million tight sands drilling program to be conducted in East Texas during the next 2 years. The program is in response to tax reform contained in the recently enacted federal budget bill. When the tight sands program is completed, the company's resulting volumes are expected to account for 1520% of Arkla Exploration's annual gas production.

OHIO OPERATORS SETTING SIGHTS ON OBJECTIVES IN CAMBRIAN, ORDOVICIAN

Feb 4, 1991 G. Alan Petzet Exploration Editor Exploration for gas in rocks of Cambrian and Ordovician age is on the upswing as the Devonian Clinton and Medina tight gas sands play starts to wind down in the Ohio portion of the Appalachian basin. The area's intrepid independent operators refer to the objective formations as Ordovician Trempealeau dolomite, Rose Run sandstone, Copper Ridge dolomite, Knox dolomite, Beekmantown dolomite, and Cambrian Rome and Mount Simon sandstones. Rose Run drilling is

GAS TRANSMISSION PROJECTS PACE PIPELINE CONSTRUCTION

Feb 11, 1991 A.D. Koen Gulf Coast News Editor Warren R. True Pipeline/Gas Processing Editor Construction of petroleum and natural gas pipelines worldwide this year and beyond will continue at a pace set in recent years. This prospect seems likely despite upstream uncertainties caused by war in the Middle East. Again leading in projected mileage are gas gathering and transmission lines, especially in the U.S., Canada, Europe, and the countries of the Asia-Pacific region. Additionally, petroleum product

CIG SCHEDULES UTAH-COLORADO GAS PIPELINE

Feb 18, 1991 Colorado Interstate Gas Co. has applied to the Federal Energy Regulatory Commission to lay 223 miles of 20 in. pipeline from eastern Utah through Northwest Colorado to its main system in Southwest Wyoming. The proposed $85 million pipeline will enable CIG to move 178 MMcfd of gas from fields in Utah and Colorado to its existing system in Wyoming and on to the Colorado Front Range area and other pipelines. Connections will provide service to the Midwest and California.

GAS INDUSTRY SLUGGISHNESS SEEN PERSISTING

Feb 25, 1991 The U.S. natural gas market quandary won't go away. Demand growth potential remains huge for what some call the fuel of the future. But prices at the wellhead seem never to get the message. Kenneth L. Lay, chairman and chief executive officer of Enron Corp., has an explanation: predatory pricing by large companies. "I strongly doubt that it has been intentional," he told a Cambridge Energy Research Associates seminar in Houston this month.

FRAC HEIGHT MAY INCREASE AWAY FROM WELL BORE

Feb 25, 1991 Ercill Hunt Ercill Hunt & Associates Inc. Houston Well logs with deep investigation capabilities are necessary to determine accurately the height of hydraulically produced fractures. Logs with shallow investigation capability will indicate the height of the fracture near the well bore, but as shown in a test in an East Texas well, fracture height in some formations can be substantially greater away from the well bore. In the East Texas test, sponsored by the Gas Research Institute (GRI), six

WESTERN PROCESSORS NEAR END OF EXPANSION

Mar 4, 1991 An expansion program under way since 1987 by Western Gas Processors Ltd., Denver, will culminate this month when the company completes the $36 million purchase of Amoco Production Co.'s Edgewood, Tex., sour gas treating plant. As part of the package, Western will buy Amoco's Jurassic Smackover crude oil and condensate production in the area. Production last year was about 2,000 b/d. The Edgewood plant, about 100 miles east of Dallas, is rated at 70 MMcfd processing capacity and 350

EXPLORATION PACE FAST IN MISSISSIPPI, ALABAMA

Mar 4, 1991 G. Alan Petzet Exploration Editor Exploration in northern and southern Mississippi and adjacent northwestern Alabama is off to a fast start in 1991. A sample of activity in the area includes a potentially significant Cambro-Ordovician Knox dolomite play building in northern Mississippi in and west of the Black Warrior basin. ARCO Oil & Gas Co. has abandoned one wildcat in northwestern Mississippi.

HORIZONTAL DRILLING TECHNOLOGY ADVANCES

Mar 4, 1991 Horizontal drilling technology is making further advances in the Texas Austin chalk play as such drilling continues to spread in many U.S. land areas. Union Pacific Resources Co., Fort Worth, has completed a Cretaceous Austin chalk oil well with the longest horizontal well bore in Texas and what at 1 1/6 miles is believed to be the world's longest medium radius horizontal displacement. UPRC's 1 Borchers Trust, 8 miles northeast of Gonzales in Gonzales County, flowed 1,162 b/d of oil and

OGJ NEWSLETTER

Mar 11, 1991 It will take 5 years to complete the reconstruction of Kuwait's oil industry, says a Kuwait Oil Co. official. Ali al-Qabindi, coordinator of KOC's well fire containment campaign, gave that gloomy outlook after an extended tour of the burning oil fields (see story, p. 30).

HORIZONTAL DRILLING TECHNOLOGY KEEPS ADVANCING

Mar 11, 1991 Guntis Moritis Drilling/Production Editor The upward surge in horizontal drilling projects shows no signs of slackening and innovative applications of the technique continue. Dual horizontal laterals are the latest innovation that may accelerate the spread of horizontal drilling.

HORIZONTAL WELLS DRILLED SUCCESSFULLY UNDER TURNKEY CONTRACT

Mar 11, 1991 Bill Johnson Forwest Inc. Houston Eric Hajas Horwell Engineering & Services Rueil-Malmaison, France Horizontal drilling technology has advanced to the point that turnkey drilling contracts can be successfully completed. Forwest Inc., Houston, drilled two such turnkey horizontal wildcat wells for Union Pacific Resources (UPRC) in Dunn County, N.D. Forwest realizes the dangers of turnkey contracts. But with a good rig, good people, and services, horizontal wells can be drilled profitably. The

JET-ASSISTED DRILLING NEARS COMMERCIAL USE

Mar 11, 1991 Mike Cure Grace Drilling Co. Dallas Pete Fontana FlowDril Corp. Kent, Wash. Recent changes in a high-pressure, jet-assisted drilling system have been successfully tested in several East Texas wells. These encouraging results will help move the system from the test stage into commercial application. The higher the formation angle or the harder the rock, the better the test for the high-pressure, jet-assisted (Fig. 1) drilling system. Grace/FlowDril, a joint venture between Grace Drilling of

STRIPPER WELL PRODUCTION INCREASED WITH MEOR TREATMENT

Mar 18, 1991 Sidney J. Nelson, Phillip D. Launt RAM Biochemicals Inc. Raleigh, N.C. Stimulation of single wells by microbial injection has proved to be an effective technique for improving marginal oil production. Microbial stimulation is particularly suited for stripper wells because of the relatively low cost for process development and testing, and even lower cost for subsequent well treatments.

NONPRODUCING HAYS COUNTY, TEX., SITE OF REMOTE ELLENBURGER WILDCAT

Mar 18, 1991 G. Alan Petzet Exploration Editor A Houston independent has staked a rare, remote wildcat in nonproducing Hays County, central Texas, in the frontal portion of the buried Ouachita Thrust Belt. Portsmouth Resources Inc. plans to drill 1 Bittick et al. to 9,500 ft or Cambro-Ordovician Ellenburger 2 miles south-southwest of Dripping Springs and 27 miles west of Austin. Location is in Stiles J. Fowler survey #31, A-174.

SPEARS TRIMS FORECAST OF U.S. DRILLING ACTIVITY

Apr 1, 1991 Forecasts of 1991 U.S. drilling activity continue to slide as oil markets shed their jitters in the wake of a very short Persian Gulf ground war. In its quarterly review late last month, Spears & Associates Inc., Tulsa, cut its projected U.S. average rig count for this year to 960. In its previous quarterly forecast, Spears expected the 1991 rig count to average 1,050. Baker Hughes Inc. earlier trimmed its predicted average of U.S. active rigs to 1,104, while Salomon Bros. forecast 1,060 (OGJ,

HORIZONTAL DRILLING SPREADING OUT IN SEVERAL U.S. STATES

Apr 1, 1991 Horizontal drilling in relatively mature U.S. onshore reservoirs continues in several states. For example, American Exploration Co., Houston, 2-15 Midway Field Unit, in Lafayette County of South Arkansas flowed at rates of as much as 900 b/d of oil through a 20/64 in. choke with 450 psi flowing tubing pressure from Jurassic Smackover open hole at 7,149-80 ft. The well, given a light acid treatment, is expected to produce a sustained 450 b/d of oil. Site is 8 miles north of Lewisville.

FRONTIERS, MATURE AREAS SHARE ONSHORE SPOTLIGHT IN LOWER 48

Apr 8, 1991 G. Alan Petzet Exploration Editor Onshore exploration in the Lower 48 east of California is busy in frontier as well as mature areas. And the action isn't confined to high-visibility horizontal and coalbed methane drilling, important as they have become to activity levels and reserves additions. Here are some highlights: The first regional seismic line, complete with geological interpretation, of the planned 16,000 line mile Megaregional Project designed to cover the entire contiguous U.S.
