Ansila accelerates to the start line for Polish flow test

Special Report: Ansila Energy (ASX:ANA) is looking to get the new year off to a running start with flow isochronal (multi-rate) testing of its Siciny-2 well in the Gora licence, Poland, due to start this week.
The test consists of a series of drawdown and build-up sequences at various flowrates to measure the deliverability and inflow performance characteristics of the well.
It will be followed by a longer flow test period and a long-term pressure build-up test to gather reservoir data over an extended period to confirm the commerciality of Siciny-2.
The Gora licence is believed to hold up to 1.6 trillion cubic feet of gas (equivalent to about 270 million barrels of oil).
All work to date has been positive with the company reporting last month the successful flowback of fracture stimulation fluids with minimal proppant returned.
This indicates that the proppant, which prevents the fractures opened by the frac from closing, has remained within the fracture created by the operation.
Siciny-2 was drilled in 2012 and had encountered 1,460m of tight Carboniferous sandstone with good and consistent gas shows throughout, while analysis of an injection test indicated good commercial potential through horizontal fracture stimulated development wells.
Ansila is earning up to 35 per cent in the Gora gas and Nowa Sol oil concessions in Poland from Gemini, which is the operator, by spending a total of $6.1m on facture stimulation and test work.
