PTTEP plugged and abandoned a new-field wildcat, SBP-B01 (BA) (Sarabop-B01 (BA)), in the S1 Reserved Area, onshore Phitsanulok Basin, on 30 June 2020, as a dry well. Spudded on 9 May 2020, it is the first well for batch drilling of two exploration wells within the area. SBP-B01 (BA) was drilled to a total depth (TD) of 4,460 m using the â50151HDâ land rig, likely targeting sandstone reservoirs of the Lan Krabu Formation.   The previous exploration drilling activity in the block was WMG D-01 that was suspended on 2 April 2020, as an oil well. The appraisal well was drilled to a TD of 2,386 m, using the â50151HDâ land rig.  The Phisanulok Basin has proven to be a prolific oil province in onshore Thailand. New oil accumulations have been found in the heavily faulted geology over the years of exploration by PTTEP. Although new accumulations could be small, early and cheaper monetisation is possible due to mature extensive network of development in the surrounding area.  The S1 Reserved Area, which also contains the Sirikit field, is operated by PTTEP with 100% interest.  Background Information  PTTEP acquired the operatorship of the Block S1 (Sirikit) complex on 30 December 2003, when it agreed to buy the entire right holdings of Thai Shell for around USD 205 million.  Shell drilled the Sarabop A-1 wildcat on 21 May 1984. The well was plugged and abandoned at a TD of 4,950 m with oil shows. It is the deepest well drilled in the country.  The S1 Reserved Area consists a total of 33 fields, including the Sirikit Complex which is under improved recovery regime. The field contributes the largest onshore crude oil production in the country.  The Phitsanulok Basin is a north-south trending intracratonic rift, covering an area about 6,000 sq km over the central plains of Thailand. The basin fill comprises alluvial fan, fan delta, alluvial plain, lacustrine delta and open lake deposits, with sediments up to 8 km thick at the western of the basin. Thai-Shell and PTTEP carried out extensive exploration and the production activities of this basin and in particular at the Sirikit Field which originally contained over 100 MMboe (P+P) of recoverable reserves.
