Drillsearch, Santos JV hits gas at Yarowinnie South-1 well

Drillsearch said it has made the second wet gas discovery by its PEL 513 joint venture with Santos.

The 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 made last month. 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. The well has been cased and suspended as a future producer.

Year-to-date, Drillsearch has drilled 20 exploration, appraisal and development wells1 as part of its FY2015 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.

In addition, Drillsearch said that Senex Energy, it’s partner and the operator in PEL 182 completed a successful production test of the Vanessa-1 wet gas discovery.

During the test, gas flowed to surface at an average rate of 5.0 million standard cubic feet per day (mmscf/d) from the Epsilon and Toolachee formations on a 65% choke (42/64ths inch). Condensate was also produced at a rate of 15 barrels per mmscf/d.

The joint venture plans to bring the well online and then consider further appraisal and development opportunities.
