Tajikistan: Field well workover exceeds 500 b/d of oil

By OGJ editors

Tethys Petroleum Ltd. reperforated and acidized the BST20 well in Beshtentak field in Tajikistan and after applying natural gas lift obtained a flow of 533 b/d of 38° gravity oil and 441 Mcfd of gas on a 25/64-in. choke with 377 psi flowing tubinghead pressure.

The well is being placed on production and the gas tied into the local grid. Sales agreements are being finalized. Beshtentak field, which has gross prospective resources of 11.7 million bbl of oil and 16.1 bcf of gas, has other workover candidates.

Elsewhere in Tajikistan, tests on the East Olimtoi-09 oil discovery continues with acidizing about to be carried out on the Upper Bukhara-Lower Alai carbonate sequence. Transportation and logistics issues have slowed arrival in country of nitrogen lift equipment, now expected in early November.

The Persea PER01 exploratory well is drilling ahead at 1,573 m and expected to reach total depth of 2,700 m. It targets a four-way dip closed prospect at Alai and Bukhara levels near the town of Kurgon-Teppa. If successful it could be brought on stream quickly.
