Following an earlier frac-test on a zone between 2,048mt and 2,058mt true vertical depth sub-sea (mTVDSS), the L27/43 block partners will conduct a second frac-testing programme for the Phu Kheng-1 well. This program will target two shallow intervals in the Phu Kradung sandstones.
The company said that both of these zones exhibited good gas shows during drilling and subsequent log analysis suggest better porosity and permeability characteristics than seen in the deeper zone. A hydraulic workover unit has been secured and operations are expected to restart in early March. The company holds a 27.2% interest in the L27/43 block.
APICO, the L13/48 operator, has suspended the Si That-3 well following the completion of a Production Logging Tool (PLT) survey. Despite gas flow to surface being measured during testing, no free gas flow was detected by the PLT tool from the reservoir above the water zone.
The company said that the gas seen at surface during testing is believed to be coming out of solution, and will be dissolved under reservoir conditions. Following the results of the PLT survey, the operator will now conduct a review of the remaining prospectivity of the L13/48 licence. The company has 16.3% working interest in the well.
The preparations of the Bang Nouan-1 well site have now been completed and the majority of trucks transporting the Century 26 rig have arrived on site. The rig is now being constructed and the well is expected to spud in the coming days.
