The wells, TGT-4P to 7P, were drilled in ‘batch’ mode, rather than drilled separately in sequence and the preliminary analysis suggests that the wells have confirmed the reservoir model.
The TGT-4P well, drilled in the southwest area of the northern fault block found the top of the target reservoir horizon lower than expected but encountered previously unmapped hydrocarbons in the Oligocene ‘C’ reservoir.
The TGT-5P well, drilled to the northern part of the field encountered the main reservoir, while the TGT-6P, drilled to the southern part of the northern fault block, encountered the main reservoir high to prognosis.
The TGT-7P well, drilled to the central area, also discovered the main reservoir horizon although it encountered a thicker pay section than expected.
Hoang Long Joint Operating Company (JOC), the operator of Block 16-1, is now drilling an eighth development well on the Te Giac Trang development.
The TGT-8P well, targeting the central area of the H1.2 fault block, near the TGT-1X discovery well, will take approximately 30 days to drill and complete.
Once the well has been completed, the rig will be released to allow for the commencement of installation operations for the in-field pipelines and FPSO to commence.
All wells are being suspended and will become producing wells upon start-up of production in August 2011.
