Eastern Baltic basin well has multizone gas, oil shows

By OGJ editors

Talisman Energy Inc. has set production casing at an indicated multizone discovery in Poland’s eastern Baltic basin.

Partner San Leon Energy PLC said the Rogity-1 well on the Braniewo S concession went to 2,788 m and encountered continuous gas shows over more than 500 m of the Lower Silurian, Ordovician, and Middle Cambrian sections. The rich gas shows consisted of heavy hydrocarbons, including C1-nC8, San Leon said.

The richness of the gas shows is consistent with a wet gas system, confirming the company’s regional model of the eastern side of the basin being in the oil window, San Leon said. The strongest gas shows, along with indications of oil, were encountered in the Lower Silurian interval, estimated to be more than 100 m thick. Oil shows were also found in Ordovician limestones and shales and in Middle Cambrian sandstone.

Talisman cut 334 m of continuous core to evaluate the reservoir properties and mechanical properties of the Lower Silurian, Ordovician, and Middle Cambrian sections. In addition an extensive open hole logging program was also performed to further evaluate the potential of the well. Evaluation and interpretation of the core and logs is expected to take 3-4 months in preparation for continued operations later in 2012, San Leon said.

Future operations could include pressure testing of the formations (DFIT test) and a possible vertical frac across several intervals. Future operations in the concession are expected to include a long horizontal well as well as a multistage frac.

Talisman will next move the rig to the Szczawno concession to drill the Szymkowo-1 well.
