CO2 AND HC INJECTION LEAD EOR PRODUCTION INCREASE

Apr 23, 1990 Guntis Moritis Drilling/Production Editor Oil production from CO2 and low-molecular-weight hydrocarbon miscible/immiscible (HC) gas injection projects is rapidly increasing in the U.S., as,,the Journal's exclusive worldwide survey in this issue shows. Since OGJ's previous worldwide biennial EOR survey in 1988 (covering the situation at the beginning of 1988), enhanced oil production has more than doubled from HC projects and increased by 49% from CO2 projects (Table 1).

LIKELY CAUSE OF GULF ACCIDENT PINPOINTED

Apr 23, 1990 A compressor on a subcontractor work boat probably ignited a mixture of natural gas and liquid hydrocarbons expelled when an 18 in. riser pipe was purposely cut last year in the Gulf of Mexico. The resulting explosion killed seven persons and destroyed ARCO Oil & Gas Co.'s Platform B on South Pass Block 60. Those are the findings of a Minerals Management Service, U.S. Coast Guard, and Office of Pipe Line Safety investigation of the incident.

REFORMULATED FUELS-CONCLUSION OPTIONS TO MEET 1990S FUEL COMPOSITION RULES LIMITED

Apr 23, 1990 George H. Unzelman HyOx Inc. Fallbrook, Calif. Reduction of aromatics in gasoline and diesel fuel, and reducing gasoline vapor pressure below current levels while maintaining fuel quality at current levels required by the consumer, will be tough challenges for U.S. refiners. A study of the current U.S. gasoline pool composition implies that processing changes are feasible to reduce average summer Rvp to 9 psi, and to reduce gasoline aromatics content from 32 to 30 vol % (close to 28 vol % if

UNION CARBIDE DETAILS ANTIPOLLUTION PROGRAM

Apr 23, 1990 Union Carbide Chemicals & Plastics Inc. has achieved major cuts in pollution emissions and waste in recent years and plans more such cuts in the near term. Ronald Van Mynen, Carbide vice-president for health, safety, and environmental affairs, outlined progress in the company's pollution prevention programs before the U.S. Senate subcommittee on environmental protection earlier this month.

PLACID HALTS ULTRADEEPWATER PROJECT IN GULF

Apr 23, 1990 Rick Hagar Gulf Coast News Editor Placid Oil Co. and partners have shut down their pioneering Green Canyon Block 29 floating/subsea drilling and production system in the Gulf of Mexico. Operations to plug and abandon the ultradeepwater site have begun in the wake of the Apr. 16 shutdown. The project's export pipeline bundle, Ship Shoal Block 207 processing platform, and Green Canyon 29 subsea drilling/production template will be mothballed in place.

INTERNATIONAL BRIEFS

Apr 23, 1990 ZIMBABWE hopes to inaugurate its chemical industry with a $110 million polyvinyl chloride plastics plant. PVC Polymer Zimbabwe Pvt. Ltd. let contract to Foster Wheeler Energy Ltd., Reading, U.K., to complete by yearend a second phase feasibility study for the project, tentatively scheduled for completion in 1993. If approved, the plant would produce 20,000 metric tons/year of PVC, as well as caustic soda, chlorine gas, sodium hypochlorite, and hydrochloric acid.

BP TO DRILL WILDCAT AT SITE OFF PHILIPPINES

Apr 23, 1990 BP Petroleum Development Ltd. plans a wildcat on a block off Palawan in the Philippines on a farmout from Crestone Energy Corp., Denver. Under the farmout agreement, BP received from Crestone 55% interest and operatorship of Geophysical Survey and Exploration Contract 54, a 5,822 sq mile block off western Palawan Island in the South China Sea. Crestone was awarded GSEC 54 last fall. Under the GSEC, Crestone received a 60% interest with remaining interests allocated to a combine of Philippine

CANADIAN OIL COMPLETIONS SHOW BIG DECLINE FOR 1989

Apr 23, 1990 Oil drilling activity in western Canada in 1989 slid to the lowest level of the 1980s, reports Canadian Oil Patch Analyst Inc. (COPA), Calgary. COPA figures show the industry completed only 1,803 oil wells in the region last year, compared with 4,251 in 1988. Natural gas completions were up slightly in 1989 at 2,349 wells from 2,337 wells in 1988. "The consensus is that there are no more 'elephant' size oil fields to be found in western Canada, and thus gas drilling has supplanted oil

METHOD ANALYZES PRESSURE FOR SHORT FLOW TIMES

Apr 30, 1990 Mohamed Soliman Halliburton Services Duncan, Okla. Kevin Petak Halliburton Reservoir Services Dallas Pressure build-up after short producing times and pressure surges can be analyzed. The method employs the derivative plot and does not require prior knowledge of initial reservoir pressure that may be calculated using a Cartesian plot. Field use of the new technique has proven its superiority to previously used methods, and has shown the necessity of using highly accurate data to achieve desired

INTERNATIONAL BRIEFS

Apr 30, 1990 THAILAND AND MALAYSIA signed a draft agreement covering joint oil and gas exploration and development of overlapping territorial claims in the Gulf of Thailand. The agreement, to be ratified by parliaments in both countries, calls for production from the area to be shared equally based on a modified production sharing system drafted from the Thai concession system and the Malaysian production sharing contract.

ALYESKA MAPS BIG CORROSION REPAIR PROGRAM ON TRANS-ALASKA CRUDE LINE

Apr 30, 1990 Alyeska Pipeline Service Co. plans the petroleum industry's most expensive corrosion repair campaign on its Trans Alaska Pipeline System (TAPS) carrying North Slope crude oil to a tanker terminal near Valdez in southern Alaska. "We are in no danger of an immediate leak, but it's something we need to address," Bill Howitt, Alyeska's manager of engineering, told Oil & Gas Journal. In addition to external corrosion along portions of its 800 mile, 48 in. main line system, Alyeska has

DEVELOPMENT PROJECTS MUSHROOM IN GULF

Apr 30, 1990 Gulf of Mexico area operators are setting a brisk pace in exploration and development. In the most expensive operation, Exxon Co. U.S.A. has decided to proceed with two significant ultradeep water gas development projects. Its plans involve: Mississippi Canyon Block 354, to be developed with a multiwell subsea system set in 1,500 ft of water. The project, known as Zinc, has been on the shelf since 1986 due to low prices and poor markets (OGJ, May 30, 1988, p. 32).

DATA SKETCHY ON LITHUANIA'S OIL RESOURCES

Apr 30, 1990 The Soviet Union's breakaway republic of Lithuania is not completely lacking in petroleum resources, as it has often been portrayed during its struggle for independence and resulting cutoff of Russian fuel deliveries. Instead, Lithuanian territory accounts for the largest area of what Moscow calls the Baltic oil province. At least 10 oil fields have been discovered in Lithuania, most of them during the late 1960s and the 1970s.

SOVIETS' CASPIAN SEA DRILLING ACTIVITY FALLS

Apr 30, 1990 The Soviet Union's Caspian Sea drilling in first quarter 1990 fell to its lowest point since the 1950s, and this year's footage most likely will be far short of target. Renewed ethnic unrest in Azerbaijan caused much of the sharp drop in Caspian drilling early this year. Problems were compounded by failure of the big fabricating yard near Baku to provide jackets for platforms as scheduled. The Soviets had hoped to increase Caspian Sea drilling by 40% in 1986-90 compared with 1981-85,

THE HAZARDS OF SOVIET BUSINESS

Apr 30, 1990 Oil companies seeking opportunities in the Soviet Union escaped calamity last week. President Bush, with support from U.S. allies, declined to cancel trade talks with the Soviet Union in retaliation for Moscow's economic embargo of Lithuania. For many reasons-among them the need for a trade pact affording some legal framework for business conduct in the U.S.S.R.-Bush made the proper call. And his handling of the matter offers a lesson to western companies certain to face Soviet crises of
