Far East-1 Well Update

Salamander Energy provides an operational update on testing operations at the Far Eat prospect in its operated B8/38 licence, Gulf of Thailand. Further to the announcement on 26th June 2012, a barefoot DST was conducted over a zone of potential oil pay in the Ratburi carbonates. The test results are conclusive, analysis of produced fluids point to formation water being present in the tested section. The Far East-1 well will now be plugged and abandoned as a dry hole and the rig is being prepared for release. The Bualuang North West Terrace exploration well will now be drilled later in the year as part of the wider exploration programme across both the B8/38 and G4/50 licence areas.

Bualuang Far East-1 Exploration Well Spud

Salamander Energy plc announces the spud of the Bualuang Far East-1 (“FE-1”) exploration well in Block B8/38, Gulf of Thailand. The Bualuang Far East prospect is located approximately 7km to the northeast and up-dip of the Bualuang oil field. The FE-1 well will be drilled to a total vertical depth of 1,452 metres subsea. The primary target is the T5 Miocene sandstones with secondary targets comprising an underlying Permian-age Ratburi carbonate and a T4 Miocene sandstone stratigraphic trap. The main T5 objective has potential mean recoverable resources of 20 million barrels of oil. The well will be drilled by the Ensco-53 jack up rig and is expected to take approximately 20 days to complete on an untested basis. Salamander has a 100% interest in, and is the operator of, the B8/38 production licence. This contains the Bualuang oil field and East Terrace oil discovery.
