Senex Begins Fracture Stimulation at Kingston Rule-1

Orca Energy, in an update with respect to its exploration for unconventional gas in the Southern Cooper Basin, has said that the Operator of PEL 115, Senex Energy has now commenced fracture stimulation operations at Kingston Rule-1.

Work over and zone perforation operations have also commenced at Hornet-1 in preparation for fracture stimulation to begin there next month. Kingston Rule-1 is the second well in a fracing program that includes other Senex 100% owned wells, with both Kingston Rule-1 and Hornet-1 located in PEL 115 (Orca 20%, Senex 80%).

The fracture stimulation program over these wells will be completed over a two-month period, with flow testing to continue into the June quarter 2013.

Kingston Rule-1 was drilled by Senex in late 2012 and intersected a total of 53 metres of net gas pay, with 9 metres in the Epsilon Formation and 44 metres in the Patchawarra Formation tight gas sands.

The multi-stage fracture stimulation of this well will target tight gas sands within the Patchawarra and Epsilon formations. To date, three of a total of six zones have been fracture stimulated with bridge plugs set between each zone. The forward operation will be to perforate and fracture stimulate the remaining three zones, drill out the bridge plugs and then flow the well to recover the frac fluid and test for gas flow from the well. Orca will continue to report when material data is available.

Hornet-1 was drilled by Victoria Petroleum in 2004 and intersected gas shows in the Epsilon Formation and 28 metres of net gas pay in the Patchawarra Formation.
