Carnarvon Petroleum drilling infill well for its onshore Thailand oil field
PERTH -- Carnarvon Petroleum has commenced drilling its infill well (NSE-B2) in the Na Sanun East (NSE) oil field. The well will be drilled to a total depth of 900 m TVD and is expected to take around 12 days to complete.
The well is targeting the NSE main volcanic in a structural high position with interpreted pay zone of around 106 m thickness based on new interpreted analysis of the 3D seismic data. If successful, the well will be placed on production within 5 to7 days following the completion of the well and production from this well is planned to be restricted to preserve low rates and maximize recovery rates.
This is an infill well into the NSE which has produced around 5 MMbbl to date and, based on December 2011 Gaffney Cline reserve report, still has around 2 MMbbl of reserves. Dependent on the results of this well, one further infill well into the NSE reservoir, based on revised seismic interpretation of fracture analysis, is being considered for the 2012 drill program.
