Quadrant Energy has begun drilling the offshore Outtrim East-1 well, located in the WA-155-P(1) exploration permit in Australia’s North West Shelf. The company will explore for additional hydrocarbon-bearing sands to the north and east of the hydrocarbon reservoir seen at the 1984 Outtrim-1 oil discovery approximately 0.6 miles away. Outtrim East-1 will be drilled to a 4,265-ft measured depth just above the Pyrenees formation, which was oil-bearing in the Outtrim-1 well. The company plans to obtain about 295 ft of conventional core before drilling the well’s final section to a 4,724-ft total depth. Quadrant is the operator with a 71.5% interest in the permit. Carnarvon Petroleum holds the remaining interest.
