No hydrocarbons for Ophir from first offshore Thailand well

Offshore staff

LONDONOphir says its G4/50-10 exploration well on the Soy Siam prospect in the Gulf of Thailand was a dry hole.

The well encountered the primary Miocene reservoir targets on prognosis in terms of both reservoir quality and depth. Preliminary analysis suggests the structure had no access to charge, which was one of the risks identified pre-drill.

Ophir will relocate the rig to drill the Parichat South West prospect, testing a different petroleum system. The Parichat complex is a cluster of four fault blocks 30 km (18.6 mi) south of the company’s producing 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. Initially Ophir is targeting the South West fault block, with prospective resources of 25 MMbbl.

If successful, the Parichat South East fault block would be next up for a well.
