(MENAFN - ProactiveInvestors - Australia) Hawkley Oil & Gas (ASX: HOG) is preparing to carry out a series of 24 hour production tests at its Sorochynska-202 development well in Ukraine.
This follows perforations of three horizons and cleaning out the well bore.
Sorochynska-202 was drilled to provide an additional production location for the Upper B18 sand.
While reservoir development of the Upper B18 appears to be slightly less than prognosed at this location, it is mitigated by the improved development of the Lower B18 with the total pay in both B18 sands being close to expectation.
The secondary objective was appraisal of the Lower B19 sand which flowed gas on test in legacy well Sorochynska-469 and in which Moyes and Co believed held a significant contingent resource.
A cased hole test of the Upper B19 had produced gas, confirming that the Lower B19 was gas saturated.
While this was not at a commercial rate, the cause of this is currently unclear and could be due to either a reservoir quality issue or possibly formation damage.
The core sample from Sorochynska-202 is being analysed and this will be integrated with well test data to determine the appropriate technology and /or well stimulation techniques to exploit this resource successfully.
Sorochynska 202 could double Hawkley's production from the Sorochynska field.
Production for the September 2012 quarter from the Sorochynska-201 well totalled 445 million cubic feet of gas and 11,902 barrels of condensate.
