GAS INJECTION AT RISER BASE SOLVES SLUGGING, FLOW PROBLEMS

Feb 26, 1990 T.J. Hill BP Research Sunbury Research Centre Sunbury-on-Thames, U.K. Test-rig studies and operating experience by BP International have shown that riser-base gas injection can help prevent severe slugging and smoothen start-up transients in subsea pipelines. The studies were based on predictions that multiphase lines proposed as part of the Forties field extension would be subject to severe slugging.

SHELL WESTERN ENLARGING CO2 FLOOD IN WASSON FIELD

Feb 26, 1990 Shell Western E&P Inc. has begun work to expand its carbon dioxide flood in Wasson field's Denver Unit, Yoakum and Gaines counties, Tex., to include the western portion of the unit as well as the eastern. Shell expects the expansion, which will cost about $100 million, to boost recovery to about 60% of original oil in place and extend field life by at least another 25 years (OGJ, Feb. 12, Newsletter). The Denver Unit CO2 flood is the world's largest in terms of enhanced production.

INDUSTRY PRESSES PROGRAM TO BOOST OIL AND GAS PRODUCTION IN NIGERIA

Feb 26, 1990 Roger Vielvoye International Editor Nigeria, West Africa's biggest oil producer, has started a major spending program to boost its oil flow in the mid-1990s. The goal is to take advantage of an expected increase in demand for oil from members of the Organization of Petroleum Exporting Countries. Money also is being plowed into gas development. Nigeria's biggest single investment in the early 1990s aims to turn the country into West Africa's first gas exporter.

NPRA O&A-1 1990S FUEL SPECIFICATIONS WILL REQUIRE PROCESS CHANGES

Feb 26, 1990 Increased demand for higher-quality fuels and tougher air-quality regulations will substantially alter the specifications for gasoline and diesel fuels in the 1990s. Higher-octane gasoline with lower vapor pressure, and diesel fuel with lower sulfur and aromatics, will require process changes to produce. These altered fuel specifications prompted several questions at the most recent National Petroleum Refiners Association annual question and answer session on refining and petrochemical

SURFACE AREA APPROACH KEY TO BOREHOLE STABILITY

Feb 26, 1990 Roy D. Wilcox Baroid Drilling Fluids Inc. Houston Clay stability models based on surface-area, equilibrium water-content pressure relationships,' and electric double-layer' theory can successfully characterize borehole stability problems. Because borehole problems are complex, a total systems approach to their solution is required.
