UKCS: Disappointment for Cairn, Success for Premier

Tolmount East

The 42/28d-14 well located in P1330, Block 42/28d (Premier 50% operated interest) UK Southern Gas Basin, was targeting 38 MMboe (P50 gross resource), in an undrilled area 4 km east of the 88 MMboe Tolmount gas field.

The well penetrated 73 m of gas-bearing high-quality Lower Permian Leman sands with NtG ratio of 71%, porosity of 16% and gas saturation of 82%.

The quality and thickness of reservoir sands encountered are at the upper end of expectations and no gas-water contact was penetrated.

This well result also has positive implications for other targets within the Greater Tolmount area, including Tolmount Far East and the Mongour discovery.

Tolmount East will be tied back to Tolmount to ensure the infrastructure is kept at full capacity. Early concept work has been completed so that an accelerated Tolmount East development could be pursued.
