LONDON -- The GS01-M1 exploratory well offshore India has been drilled to a total depth of 4,326 m (14,193 ft) TVDRT to explore the Oligocene and Eocene carbonate targets, according to Hardy Oil and Gas. Porosity development was observed in the Oligocene target but no proper seal was present.
Gas shows with heavier end hydrocarbons were recorded while drilling the mid-Eocene target zone over a 20 m (66 ft) interval, the company says. However, the middle Eocene carbonate could not be drilled in its entirety due to pressure limitations of the rig. Well logs showed reservoir development but the MDT tests were inconclusive and a conventional DST was not conducted. The well has now been plugged and abandoned.
The joint venture is planning to continue to evaluate the M1 prospect by carrying out advanced processing of the 3D seismic data and integrating the new drilling data.
Scheduled drilling of the GS01-B2 appraisal well has been delayed and further drilling on the block is not expected to begin until the latter part of 2009.
