Pogo Producing Company Drills Second Exploratory Well on Benchamas Seismic Structure in Gulf of Thailand

Strategic Insights -

Pogo Producing Company, in partnership with Rutherford-Moran Oil Corporation and Maersk Olie og Gas As, has successfully drilled and tested a second exploratory well on the large Benchamas seismic structure located on Block B8/32 in the Gulf of Thailand. The company plans to immediately drill additional Benchamas wells to further explore the potential of the structure. The recent well has yielded promising results, with four drill-stem tests conducted on the sands encountered, showing calculated cumulative daily flow rates of 33.3 million cubic feet of natural gas and 7,575 barrels of oil or condensate per day.

Key Takeaways:

  • The second Benchamas well has shown significant promise, with four drill-stem tests yielding calculated cumulative daily flow rates of 33.3 million cubic feet of natural gas and 7,575 barrels of oil or condensate per day.
  • The tests were conducted on various intervals, with gas rates ranging from 10 to 20 million cubic feet per day, and oil and condensate rates ranging from 5,000 to 7,500 barrels per day.
  • The wells were tested at an average flow rate of 1,632 feet of water column with a total flowing wellhead pressure of 1,250 pounds per square inch (psi).
  • The first Benchamas exploration well, drilled in May 1995, showed calculated cumulative daily rates of 44.7 million cubic feet of natural gas and 4,835 barrels of oil or condensate per day.
  • Pogo and its joint venture partners, Rutherford-Moran Oil Corporation and Maersk Olie og Gas As, hold a combined 63.34% working interest in the Benchamas area, operated by Maersk Olie og Gas As.
  • The Siam Commercial Bank has announced plans to drill additional exploration wells in the Bachamas area, following the positive results of the recent test.
