Drilling of 1st Shallow Light Oil Exploration Well Under Way in Kyrgyzstan
Manas Petroleum reported that the drilling of an exploration well at the North Ayzar -1 (Tuzluk license) prospect by the Kyrgyz joint venture, SPC (South Petroleum Company) is under way. The North Ayzar- 1 is to test tertiary-aged (Palaeogene) clastics and carbonates reservoirs between 1650 and 1900m. Projected total dept of this well is 1950m and it is expected to take from 20 to 30 days to drill.
Following the drilling of the North Ayzar-1, the drill rig is scheduled to be moved to a second deeper prospect called the Huday Nazar in the Soh license area where drilling would commence approximately 2 weeks later. Should drilling be sufficiently encouraging, testing and completion of the wells would be made following the drilling of the Huday Nazar.
The offset analogue field to the North Ayzar prospect is the Beshkent-Togap Field (10 MMBO) which is 5km (3 miles) to the Southwest. The P50 mapped closure on North Ayzar prospect is 3 square km while the net thickness of the targeted reservoirs (using the productive limestone and sandstone strata from analogue fields) is estimated according to calculations by RPS Scott Pickford to be 12 meters with 17.83% porosity.
The P50 mapped closure for the Huday Nazar prospect is approximately 6 square km and the planned depth of the well is 2400m. The Huday Nazar prospect was generated as a result of the processing of seismic shot in a recent 2D seismic program by SPC. Analogue fields for the Huday Nazar are the North Rishtan (1 MMBO) and North Soh (13 MMBO, 130 BCF). The Huday Nazar replaces the previously planned drilling of the smaller and shallower East Chongora prospect which is also in the Soh License area.
Acquisition of a total of 800 km of 2d seismic within the SPC licenses was completed as of late May 2009 and seismic processing is on-going. Preparations are under way for 2010 deep drilling program which is expected to commence early 2010.
