Gas Flows for Aurelian's Trzek-2
Aurelian Oil and Gas has announced hydraulic fracturing operations for first Siekierki Multi Fracced Horizontal Well ("MFHW") Trzek-2 have been successfully completed.
An initial production rate of 17mmscf/d was recorded on Trzek-2 on a short-term test, compared with an initial production rate of 7.5mmscf/d recorded for the Trzek-1 vertical well on a similar short-term test in 2007.
Ten separate zones were successfully fracture stimulated along the 1350m of horizontal wellbore.
Aurelian plans to plans to flow the well for a further 30 days once the clean-up process is completed on order to ascertain a stabilized flow rate, to be used by the Company to estimate an ultimate recovery from the well.
The Company currently estimates that Trzek-2 will be completed in line with its original budget estimate of €18.2 million.
Trzek-3, the second Siekierki MFHW, drilling ahead as planned
Trzek-3 is currently drilling ahead at approximately 2500 metres, with the vertical pilot hole and the horizontal section expected to be completed by late May or early June 2011. Hydraulic fracturing operations will then follow, with stabilized flow test results expected by late June or early July.
Trzek-3 is targeting a separate high in the Siekierki structure with a recoverable resource estimated at between 16 and 28 bcf.
The Siekierki project is located on the Poznan licences, which are 100%, held by Energia Zachόd Sp. z.o.o., a company owned 90% by Aurelian and 10% by Avobone N.V.
Rowen Bainbridge, Aurelian Chief Executive commented:
"Aurelian is the first company to successfully use Multi Frac Horizontal Wells in Tight Gas reservoirs in Poland and to produce a very good initial flow rate is a great result. This represents an important step forward in the delivery of Aurelian's plan to develop our 346 bcf project at Siekierki. Our second Multi Frac Horizontal Well, which spudded on the 26th of January, is also making good progress and I look forward to providing further updates on this core asset in the coming months."
