Senex continues development in Surat and Cooper basins

Senex Energy has continued to deliver its Surat Basin natural gas development projects on schedule, reporting “excellent progress” at Project Atlas and Roma North.

The company has completed the drilling of 15 wells across the two sites, including five at Project Atlas and 10 at Roma North.

Project Atlas’ drilling results saw net coal intersections of up to 43 metres while at Roma North, the first pod of four wells tied into the site’s gas compressor station has resulted in immediate gas contribution.

The first Roma North compression train is also operating at maximum capacity and above eight terajoule’s per day.

Senex’s managing director Ian Davies said the results from the initial drilling campaign demonstrate good progress in the Surat Basin.

“We continue to deliver our Surat Basin gas developments on schedule, on budget and with excellent safety and environmental performance,” he said

“The initial results from both Roma North and Atlas production areas are of high quality and are a great start to the campaign.”

The update follows Senex’s recent announce that it has completed the production test of the Gemba-1 exploration well in the Cooper Basin, enabling the well to be brought online by the end of this year.

Following a seven-stage hydraulic fracturing program, a five-day production test was completed in August this year.

Gemba-1 produced at a stable flow rate of five million standard cubic feet per day on a 28/64 inch choke.

Senex has reported that production logs show gas contribution from all of the seven stimulated zones and a condensate to gas ratio of approximately 14 barrels per million standard cubic feet of gas.

Gemba-1 is expected to be tied into the Santos-operated gas gathering network in late 2019, with processed sales to then be sold into the domestic South Australian market.

Senex received a plan for accelerating exploration (PACE) gas grant of $5.26 million from the South Australian Government to progress the Gemba project.

Davies said the production test confirmed the company’s views on the gas discovery.

“Test results have proved very encouraging and we are now focused on bringing this gas discovery into production,” Davies said.

“We will see new gas supply from the Gemba field delivered to the South Australian market by the end of 2019, and we look forward to fully appraising the extent of the Gemba field.”

The wholly-owned Senex project is on the southwest margin of the Allunga Trough, five kilometres from existing infrastructure and approximately 37 kilometres south west of the Moomba processing facility.
