Results of G4/50-10 Exploration Well

Ophir announces that it has completed operations on the G4/50-10 exploration well that was testing the Soy Siam prospect. The well reached a total depth of 1,627 metres (True Vertical Depth Sub-Sea) and encountered the primary Miocene reservoir targets on prognosis in terms of both reservoir quality and depth. However, all reservoirs were dry and no hydrocarbon shows were encountered. The well has therefore been plugged and abandoned as a dry hole. Preliminary well failure analysis suggests that the structure had no access to charge, which was identified pre-drill as one of the key risks. The rig will now move to drill the Parichat South West prospect. This well is independent of Soy Siam as it is testing a different petroleum system. The Parichat complex is a cluster of four fault blocks located 30 km south of the Bualuang field that have potentially been charged from deeper in the South Western Sub-Basin. Each fault block has multiple stacked, Miocene and Oligocene reservoir targets. The South West fault block is the initial target with a mean prospective resource of 25 MMbo and a 32% chance of success. If successful, the Parichat South East fault block would form an immediate follow on location.

Ophir Energy begins new exploration campaign in Thailand

Ophir Energy Plc (“Ophir”) has announced that it has commenced a two well exploration drilling program in Block G4/50, in the western Gulf of Thailand with the spud of G4/50-10 exploration well on the Soy Siam prospect. The G4/50 Block partly surrounds Ophir’s producing Bualuang oil field and spans a series of Tertiary aged sub-basins in the western Gulf of Thailand. The two well program will test whether there is a working hydrocarbon system in one of these, the presently undrilled South Western Sub-Basin. The main play risk is considered to be charge, specifically source distribution and maturity. The Soy Siam Prospect comprises a single fault block which has potentially been charged from both the Bualuang and South Western Sub-Basins. The G4/50-10 well is targeting Miocene sandstones that are the age equivalent of the producing reservoirs in the Bualuang oil field, located 15 km to the north. The Soy Siam Prospect has 25 MMbo of mean prospective resource and a 21% chance of success. On completion of the G4/50-10 well, the rig will move to drill the Parichat South West (SW) prospect. The Emerald Driller jackup rig is being used for the G4/50 drilling programme. The estimated cost of the two well program is USD18 million and it is expected to take approximately 50 days to complete.
