Chrysaor drills non-commercial discovery in southern North Sea

Chrysaor Norge AS drilled a non-commercial discovery in the Jerv well in production license (PL) 973 in the southern North Sea.

Well 15/12-25, the first exploration in PL973, was drilled by the COSL Innovator rig in 86 m of water (OGJ Online, Feb. 18, 2021). The well was drilled to a total depth of 2,795 m below mean sea level and targeted petroleum in reservoirs of Paleocene age (Ty formation), terminating in limestone, also assumed to be of Paleocene age.

The well encountered a 40 m gas condensate column in a reservoir with good to very good quality. No gas-water contact was observed. The well was not formation tested but coring, sampling, and data acquisition were performed including pressure data. Reservoir pressure is highly depleted, and remaining resources are interpreted to be insufficient for development.

Chrysaor is operator of PL973 (50%) with partners OKEA (30%) and Petoro AS (20%).
