Solid flow boosts ARC confidence in Xyris

ARC Energy is confident of a commercial find with its Xyris-1 well after perforating a 24 metre i...

The flow was run without a separator so all figures are company estimations. The test has, however, allowed optimum design of the production test which will be undertaken shortly to obtain reserves information and provide more accurate confirmation of these initial results once a suitable separator is available.

The clean up flow was conducted using a series of choke sizes up to a maximum of 36/64 inch with the well head flowing pressure at this choke size being 1993 psi. Field gas composition measurements indicate the gas to be low in CO2 and hence of good quality.

The well has now been shut-in pending the commencement of the production test.

“This is an outstanding result for the first gas exploration prospect to be drilled in the 3D seismic grid. The gas is of good quality and the reservoir can obviously deliver at high rates. Although it will be necessary to wait for the results of the production test for final confirmation of the reserves volume, we are confident the field is of commercial size, and we will be moving to develop it as soon as possible,” said managing director Eric Streitberg.

“After the Century 11 rig completes the Jingemia 4 well in the adjacent EP 413 permit, it will be coming back to L1 to drill the next gas exploration well, Apium 1, which is on a similar structure to Xyris and we look forward to that with confidence.”

The Xyris 1 well is located 6.5 kilometres east of the Hovea Production Facility and 1.2 kilometres northwest of the Mondarra Gasfield.

Participants in L1 and L2 (excluding the Dongara, Mondarra and Yardarino fields) and Xyris 1 are ARC Energy 50% (Operator) and Origin Energy Developments 50%.
