PROCEDURE REDUCES PROBLEMS AND COSTS OF CHEMICALS IN GAS SYSTEMS

May 14, 1990 Yulin Wu Phillips Petroleum Co. Bartlesville, Okla. Efforts to evaluate problems associated with chemicals used in natural gas and NGL transportation and processing have lowered costs for one segment of an NGL system operated in Texas by Phillips Petroleum Co., Bartlesville, Okla. Phillips' procedure consisted of two steps: Scientifically evaluating chemicals and the problems they generate Following experience and expertise in selecting chemicals and solving problems. If experience and

INTERNATIONAL BRIEFS

May 14, 1990 MARATHON PETROLEUM IRELAND LTD. spudded the first delineation to a Celtic Sea oil and gas strike off southern Ireland. Its 48/24-3 discovery well flowed 1,600 b/d of oil and 5.4 MMcfd of gas about 16 miles south of Kinsale Head gas field. Drilled to 8,475 ft in 331 ft of water, the well was suspended pending evaluation. It was the last of five wells Marathon committed to in order to settle a long dispute over gas pricing. Marathon has an option to drill another five wells.

MONITORING SYSTEM TESTED DURING LPG TANKER UNLOADING

May 14, 1990 A specially developed computer-based hazardous-materials monitoring system was successfully field tested late last year. The test of the portable system occurred during the unloading of 45,000 metric tons of LPG from a 740-ft tanker at the petroleum dock of a plant along the Mississippi River. The function of this system is to detect, report, alarm, and record unacceptable concentrations of hazardous vapors during marine-transfer operations.

OPTIMIZATION AT WYOMING GAS PLANT IMPROVES PROFITABILITY

May 28, 1990 Lynn E. Saha Amoco Production Co. Houston Andrew J. Chontos Amoco Production Co. Evanston, Wyo. David R. Hatch ChemShare Corp. Houston Amoco Production Co. has implemented a computer-aided manufacturing system for on-line optimization at the Painter complex (Wyoming) gas-processing plant. The system is based on rigorous process modeling techniques using real time data. Early results show significant potential for improving the plant's profitability.

OGJ GROUP'S RESERVES STABLE IN '89 BUT LIQUIDS PRODUCTION, DRILLING DIVE

May 28, 1990 Robert J. Beck Economics Editor Joan Biggs OGJ Energy Database The Oil & Gas Journal group of 22 large U.S. oil and gas companies produced more gas, less oil and natural gas liquids, and drilled 22.7% fewer net wells in 1989 than in 1988, analysis of their annual reports shows. The group's world gas reserves were slightly higher at yearend 1989 and world liquids reserves slightly lower than at the end of 1988. The group's crude runs to stills were up a combined 0.9% from the 1988

OPERATORS BOOST OFFSHORE ACTION WHERE LEASES, PERMITS AVAILABLE

Jun 4, 1990 Bob Tippee Managing Editor-Economics and Exploration Bob Williams Senior Staff Writer Offshore exploration and development activity is growing in the shrinking U.S. area where it is allowed. The Gulf of Mexico remains the nation's busiest offshore drilling arena. Brisk leasing during the past several years, the need to replace rapidly depleting natural gas reserves, and the promise of world class oil reserves in water deeper than 1,000 ft drive the action.

FINDING, REPLACEMENT COSTS FALL IN ALBERTA

Jun 4, 1990 Canadian Energy Research Institute (CERI) estimates for 1988 long term oil equivalent finding and replacement costs in Alberta show a sharp 5 year decline. Gas finding and replacement costs also have declined greatly in the same 5 year span, CERI figures show. The decreases in Alberta crude oil finding and replacement costs, although not as abrupt as those for gas and oil equivalent, reflect the same downward trend.

INDIA'S STATE FIRMS PRESS CAMPAIGN TO HIKE OIL AND GAS FLOW

Jun 4, 1990 India's state oil and gas companies are stepping up efforts to find and develop more hydrocarbons. The state companies and petroleum ministry are shifting their strategy on exploration in India for the early 1990s. Impetus for the shift comes mainly from the recognition that India's reserves additions in recent years have lagged production. India projects its energy demand will soar as a result of population growth and efforts to maintain the pace of industrialization. Thus, the

SOVIET VENTURE MAY INCLUDE TENGIZ

Jun 11, 1990 More action on upstream joint ventures with the Soviet Union is surfacing. Among the latest developments: A protocol of intentions could add giant Tengiz oil field to a proposed Chevron Corp.-Soviet joint venture in exploration, production, and development in the Northeast Caspian Sea region. Tengiz is the largest oil field discovered in the world in the last 10 years, said Leonid 1. Filimonov, Soviet oil and gas minister.

SHELL'S RESID FCC TECHNOLOGY REFLECTS EVOLUTIONARY DEVELOPMENT

Jun 11, 1990 Mart J.P.C. Nieskens, Frank H.H. Khouw Shell Internationale Petroleum Maatschappij B.V. The Hague Martin J.H. Borley Shell U.K. Ltd. Ellesmere Port, U.K. Karl-Heinz W. Roebschiaeger Koninklijke/Shell-Laboratorium Amsterdam Commercial operating experience has been gained on conversion of long residues by fluid catalytic cracking (FCC) in a long-residue catalytic cracking unit at Shell U.K. Ltd.'s Stanlow refinery in Ellesmere Port, U.K. The unit design is the result of many evolutionary

EPA TO TOUGHEN RVP LIMITS FOR SUMMER 1992

Jun 18, 1990 The U.S. Environmental Protection Agency plans further reductions in gasoline volatility for summer 1992. EPA said the new rule will reduce national emissions of volatile organic compounds (VOCs) by nearly 7% and reduce formation of smog. It estimated the tougher rule will cost refiners $464 million/year and increase retail gasoline prices by about 1 o/gal. EPA added that would be offset partially by benefits, including greater fuel economy, estimated at $234 million/year.

TENGIZ HOLDS PROMISE, PROBLEMS FOR SOVIETS

Jun 18, 1990 The U.S.S.R.'s Tengiz oil field near the northeast coast of the Caspian Sea in western Kazakhstan has posed the Soviet Union's most difficult problems in evaluating and developing a supergiant reservoir. Tengiz probably will not be developed enough to permit an accurate determination of reserves until 1995, Soviet geologists say. However, it's possible the timetable could be advanced if a joint venture between Moscow and Chevron Corp. goes into operation and includes Tengiz (OGJ,

NEW AND MODIFIED PROCESSES AND CATALYSTS NEEDED FOR NEW FUELS

Jun 18, 1990 Reformulated gasoline and diesel fuel will stretch existing refining processing configurations to the limit, and they will likely require some new processes. As a result, refineries could look substantially different by the end of the 1990s. Reduced gasoline aromatics, olefins, and benzene contents and lower gasoline vapor pressure will mean that major gasoline producing processes, such as fluid catalytic cracking (FCC) and catalytic reforming, will have to change. Other processes, such as

FUEL REFORMULATIONS, ALTERNATIVES COVER BROAD SPECTRUM

Jun 18, 1990 Transportation fuel composition has been targeted as a major factor in the type and quantity of vehicle emissions. Gasoline vapor pressure and its benzene, aromatics, olefins, and oxygen contents, and diesel fuel sulfur and aromatics contents can all be factors in overall air quality in the U.S. The issues surrounding these and other factors were introduced in the first article of this report.

SEVERAL U.S. GAS PIPELINE PROJECTS ADVANCE

Jun 18, 1990 A number of gas pipeline projects are on the move in the U.S. Valero Energy Corp., San Antonio, disclosed plans for a 105 mile extension of its partnership's North Texas line, to cost about $58 million. Saginaw Bay Pipeline Co., a unit of MCN Corp., Detroit, broke ground at Kalkaska, Mich., for a 126 mile line to carry Cambro-Ordovician Prairie du Chien production. Oklahoma-Arkansas Pipeline Co., which was joined by Sabine Pipe Line Co., Houston, received 535 MMcfd in precedent contracts
