Europe and North Africa-focused San Leon Energy announced Friday the successful completion of its second shale gas exploration well in Poland's Baltic Basin.
The Talisman Energy operated Rogity-1 well, on the Braniewo S Concession in Poland, has been drilled to a depth of 9,150 feet (2,788 meters). During drilling continuous gas shows were encountered over more than 1,600 feet (500 meters) of the Lower Silurian, Ordovician, and Middle Cambrian sections.
The rich gas shows consisted of heavy hydrocarbons, including C1-nC8. 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. The strongest gas shows, along with indications of oil, were encountered in the Lower Silurian interval, which is estimated to be over 320 feet (100 meters) thick.
Oil shows were also encountered in Ordovician limestones and shales, and in Middle Cambrian sandstone.
1,090 feet (334 meters) of continuous core were taken in the well 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 between three and four months in preparation for continued operations later in 2012.
The well was completed and cased for future operations, which could include pressure testing of the formations (DFIT test) and a possible vertical frac across several intervals. Future operations in the Braniewo S Concession are expected to include a long offset horizontal well as well as a multistage frac.
Talisman will next move the rig to the Szczawno concession to drill the Szymkowo-1 well.
"We are excited by the successful drilling and significant data gathering at the Rogity-1 well. Our initial results show the regional variability of the basin and have confirmed our model of a more liquids rich system on the eastern edge of the basin," said San Leon Chairman Oisin Fanning.
"This is yet another milestone for San Leon and our successful partnership with Talisman Energy. Our continued systematic approach towards evaluating our geographically and geologically diverse unconventional gas acreage in Poland is paying off."
