Ansila Energy NL (ANA) has successfully completed the pumping of a hydraulic fracture stimulation of the Siciny-2 well, prior to the well test.
Following yesterday’s announcement, Halliburton has successfully completed the pumping of a hydraulic fracture by pumping water, frac gel, ceramic proppant into the Carboniferous reservoir across two perforated intervals.
The intervals were at 3,413 metres and 3,272 metres. The frac program was pumped with a stable pump rate and pressure throughout.
Once the frac was completed, the well was shut in and then later opened up. The flow-back of the frac fluids from the reservoir has started and the well is currently flowing back the frac fluids to surface.
ANA said this will continue for a few days, prior to the testing.
“With successfully pumping the frac we have hit another major milestone in the appraisal of the tight gas Carboniferous reservoir in the Siciny-2 well,” Technical Director Chris Lewis said.
Following the flow back, the well will be shut-in for a period to run in production tubing, a packer and downhole pressure gauges via the Ekranpol workover rig in preparation for the isochronal well test.
After the isochronal test, there will be a longer flowing period and a long-term transient pressure build-up test to gather reservoir data over an extended period.
The pressure build-up data, together with the flow rate data – will confirm the potential commerciality of the Siciny-2 well.
“We are now looking forward to flowing the well and gathering data later this month and into 2020,” Chris added.
On market close, ANA is down 4.88 per cent and is trading at 3.9¢ apiece.
