Tethys Petroleum has declared that drilling operations have been started at the AKD07 exploration/appraisal well located in Kazakhstan. The company has begun the additional seismic acquisition in Tajikistan.
The appraisal well, which lies to the Doris field’s south-eastern part, is specifically designed to focus on a potential downdip field expansion at the Cretaceous Aptian sand level, and appears to be a portion of a huge, separate sheet sand or sand fan system. The well includes a deep Jurassic level target that was analyzed from the three-dimensional seismic.
The company is expected to take around 55 days to drill the well to a proposed depth of 2,540 m with the help of its ZJ70 "Telesto" rig. As part of the seismic program, the company has started seismic data acquisition in Tajikistan.
The preliminary analysis of the aerial graviometry survey data, which was completed last year end together with regional seismic and well data, showed many potential regions with the occurrence of huge deep sub-thrust and sub-salt prospects in the Bokhtar production sharing contract (PSC) region.
The currently acquired additional seismic will focus on the best regions and give the last data in a detailed program. The program is specifically designed to discover a potential drill site for the preliminary deep well, which is expected to be drilled next year.
The seismic program includes the purchase of new seismic in the Dushanbe Step and Vaksh Valley. The program has been specifically designed to concentrate on these regions, as the data have discovered them to host huge deep prospects that contain prospective Jurassic reefs. Jurassic reefs form most productive fields located in the Amu Darya basin. The Amu Darya basin is productive and contains oil, condensate and gas fields. These data shows considerable potential in other portions of the PSC regions.
This recent seismic program is expected to validate the high prospective in the Tethys Bokhtar PSC acreage, wherein the company holds 85% interest. The company is discussing with several potential farminees in order to finalize a contract by year-end.
Additionally, the company has begun the proposed workover program at the Beshtentak field including preparation of well location for the initial two candidate wells, and is expecting results during the fourth quarter of 2012.
