The Coaster exploration well on UK Block 28/10 will be abandoned as a dry hole, while the Benteng-1 well on the Buton block in Indonesia will be plugged and abandoned after making a small oil discovery, which the company said could potentially be commercial.
Good oil shows were encountered in over a 111 feet interval in Benteng-1 and log analysis indicated a 15 feet oil bearing reservoir, making it the first well to discover hydrocarbons in the frontier Buton basin.
The results of this well will be integrated into the existing data base to determine whether the discovery is commercially viable and if there is follow on potential in the shallow play type across the basin.
“The Coaster and Benteng wells were both assessed as very high risk pre-drill,” said chief executive of Premier Simon Lockett.
“The Benteng-1 results are encouraging as they have established a working petroleum system in a previously unproven basin.”
The next exploration well to be drilled by Premier in Asia is the Chim Sao Northwest appraisal well, which is due to spud in July, while the next well in the North Sea, the company plans to start drilling the Spaniards East well on UK block 15/25a in September.
Shares in Premier dropped one percent to 336 pence by 8:35am, giving it a market cap of £1.78 billion.
