The Ministry of the Environment announced the latest update on shale gas exploration concessions in Poland. The number of shale gas exploration and/or appraisal concessions has slightly decreased and is now equal to 53 (as of 1 January 2015).
The concessions were awarded to 17 Polish and foreign entities (concession holders). In terms of concessions held, PGNiG is the leader with 12 concessions, followed by Orlen Upstream Sp. z o.o. with 9 of them and Lotos Petrobaltic SA with 7 offshore concessions.
Comparing with the last month, there are 3 less concessions: Chevron relinquished two (Kraśnik i Frampol) and Lotos Petrobaltic one of them (Sambia W offshore concession). New shale gas exploration and/or appraisal concessions were not awarded.
Since 2010, 68 shale gas exploration wells, including 16 directional/horizontal ones, have been completed in Poland. To wells are in drilling:
- Pęclin - OU1 well in the Mazowsze Province (Otwock District, Wiązowna Commune) drilled by Orlen Upstream Sp. z o.o. at the Wołomin Concession,
- Rawicz 12-SL-1 well in the Wielkopolska Province (Rawicz District, Rawicz Commune) drilled by San Leon Rawicz Sp. zo.o. at the Rawicz Concession.
In the past years, the progress of shale gas exploration drilling was as follows:
• 2010 - 3 wells,
• 2011 - 12 wells,
• 2012 - 24 wells,
• 2013 - 14 wells,
• 2014 - 15 wells.
Special jobs have been performed in some of the wells to initially assess the shale gas production potential. Hydraulic fracturing was performed in 25 wells (37% of all wells drilled), including 12 horizontal legs.
DFIT (Diagnostic Fracture Injection Test) was performed in 4 wells. Special jobs are still to be made in 39 wells.
Four wells are scheduled for drilling in the near future, namely: Lubocino-4H, Jackowo LEp-1, Lewino-2H in the Pomerania Region and Zwierzyniec-2 (Lublin Region).
