San Leon Identifies Potential Shale Zones in Poland
San Leon Energy has announced that it has identified a number of potential shale gas zones following the drilling, evaluation and casing of the Siciny-2 well in Poland.
During drilling, San Leon identified four potential shale intervals, which made continuous gas shows (C1-C3). Another continuous gas show was seen through a tight sandstone interval. The fourth prospective shale interval was newly discovered during the drilling and had not been seen before. This, together with the tight gas sandstone , was encountered below a depth of 3,200 metres.
The Siciny-2 well is located on the Gora Concession, in the SW Carboniferous Basin, a licensing area that covers approximately 880,000 acres to the south of the city of Zielona Gora. San Leon is the 100 per cent shareholder in the licence.
The well was drilled to a depth of 3,520 metres after penetrating more than 1,000 metres of Carboniferous section. The company took over 265 metres of continuous core from the three known prospective intervals identified in the Siciny-1 well. Rock analysis will now be performed on the core to assess the shale gas and tight gas's potential for commercial production. The evaluation is expected to take between three and four months and will reduce drilling time in the future, after giving the company valuable data into the structure of the section.
Oisin Fanning, Chairman of San Leon Energy, called the results a "milestone" for the company.
"We are encouraged by the initial results of the Siciny-2 well showing four potential zones for unconventional gas production, including a newly identified interval," he said. "In total we encountered more than 500 meters of potential reservoir for further analysis and possible testing.
"The complex nature of the Carboniferous source rock, including natural fracturing, shows real promise for gas production. Based upon these initial results we have completed the well for future testing operations.
"The successful drilling and completion of the Siciny-2 well is another milestone in proving our operating capabilities and the potential of our diverse exploration portfolio."
