Independently Certified Resource

Netherland, Sewell and Associates (NSAI) have independently re-certified an unrisked prospective resource of up to 910 MMBBL and 3,105 BCF gas (446 MMBBL oil and 1,521 BCF gas* to Petrel’s 49% net interest).

The update to the initial January 2015 resource certification by NSAI integrates recent amplitude versus offset (AVO) analysis of seismic data from the 2014 597 kilometre 2D seismic acquisition programme. AVO anomalies particularly at the top of structural highs may represent the presence of gas-filled sandstone reservoirs.
