Time to review exploration DSTs: Second Chance oil discovery – the Tarbat oil field story

Abstract

The first well drilled (Tarbat 1) was plugged and abandoned over the Hutton Sandstone after an on-depth, mechanically sound DST flowed 1080 BWPD 1% oil. Tarbat 2 was drilled 7 years later, the Hutton DST flowed 2037 BOPD and no water. This talk discusses how a valid DST test can be misleading and encourages a discussion regarding a Surat basin oil project where a re-evaluation of seismic and exploration well’s DSTs has justified a 3-D seismic which has changed the area's prospectivity.
