Touchstone Exploration has announced final production test results from the #1ST1-Cascadura well in Trinidad’s Ortoire exploration block. Two sections were tested: an upper zone from 5,570 ft to 5,915 ft and a lower zone from 6,056 ft to 6,218 ft. The upper zone (Cruse and Herrera) had an absolute open flow rate of 390 MMcf/d of gas and averaged 5,472 boe/d (86% gas). The lower test (Herrera) flowed 92 MMcf/d with an average of 5,157 boe/d (87% gas). Both tests were limited by the capacity of surface test equipment.
Exxon Mobil Corp. has mobilized a drillship to drill and perform an exploratory test in offshore Guyana’s Kaieteur Block. The venture, #1-Tanager, is targeting prospective resources of 256.2 MMbbl of oil. Current estimates for the site range from 135.6 MMbbl to 451.6 MMbbl of oil. The planned depth is 8,000 m, targeting the stacked Maastrichtian to Turonian reservoir intervals in the southern part of the block. The #1-Tanager is the first well in a potential multiwell drilling campaign being operated by Exxon Mobil on the Kaieteur and Canje Blocks over the next six to 12 months. This campaign will evaluate high-impact, Upper Cretaceous prospects in the Liza play fairway with possible multiple stacked reservoir targets.
