Aurelian Oil & Gas PLC is suspending plans for a sidetrack at the Trzek-2 well and reviewing the possibility of gas sales from the existing three wells at its Siekierki tight gas project near Poznan in west-central Poland.
Initial data indicate that gas recovery from the Trzek-3 multiply fractured horizontal appraisal well could be 4-8 bcf rather than the 16-20 bcf the company expected. Flow tests will continue to the end of September.
The Permian Rotliegendes sandstone reservoir below 3,000 m has a midcase 1.6 tcf of gas in place and covers 150 sq km, of which only 2.5 sq km has been appraised (OGJ Online, Mar. 1, 2010). The company plans to protect capital until it understands the reasons why gas rates are lower and water rates higher than anticipated.
Energia Zachod Sp. z.o.o., a company owned 90% by Aurelian and 10% by Avobone NV, owns 100% interest in the Poznan licenses.
