Santos, Drillsearch Make Second Gas Discovery in Cooper Basin

Santos and Drillsearch Energy have made second wet gas discovery in PEL 513 in Australia’s Cooper Basin.

Yarowinnie South-1 well was drilled to a total depth of 3,142 metres as an exploration well, southwest of the Varanus South-1 discovery announced last month, Drillsearch said Friday.

Drillsearch’s preliminary interpretation of wireline logs has confirmed an aggregate best estimate of almost 15 metres of net gas pay over several intervals in the Patchawarra Formation totalling a gross Patchawarra interval of 410 metres.

Drillsearch has 40 percent stake while Santos owns 60% and is the operator.   

Year-to-date, Drillsearch has drilled 20 exploration, appraisal and development wells as part of its 2015 work program, with Yarowinnie South-1 the 15th successful well in the campaign and the fifth new oil or wet gas discovery for the year.
