The review revealed that oil has been found in all 'valid' wells drilled in the area and is extensive throughout Greater Wichian Buri. To this point in time 19 wells have been drilled in the Wichian Buri sub-basin of which all 15, drilled on valid structures, have found oil or gas.
The most likely size of the resource is estimated to be around 200 million barrels of oil in place. The Estimated Ultimate Recovery (EUR) of oil over the life of the field has a most likely or 'P50' value of some 23 million barrels of oil (MMBO).
The EUR ranges from a proved volume of 11 MMBO (P90) to a possible 45 MMBO (P10). To date approximately 0.6 MMBO has been produced from the field so that the most likely remaining volume of oil that can be recovered from the field is 22 MMBO.
L44/43 encompasses the existing oil discoveries at the producing Si Thep Oil Field and the Na Sanun Oil Field as well as the gas discovery at Bo Rang. The block encompasses all of the southern part of the Wichian Buri Sub-Basin portion of the Phetchabun Basin.
Carnarvon has a 40% interest and the operator, Pacific Tiger, has the remaining 60%.
