Shale gas exploration status as of October 2015

As of 30 September 2015, there were 33 active oil/gas exploration and/or appraisal concessions that covered also the shale gas. The concessions were awarded to 10 Polish and foreign concession holders, who have drilled a total of 71 exploratory wells by 30 September 2015.

Comparing with the record year of 2012, when 113 concessions were in effect, as much as 80 concessions ave been relinquished.

September saw a change in exploration leadership in terms of concessions held. Currently three companies hold 7 concessions: Orlen Upstream Sp.z o.o., Shale Tech Energy Sp. z o.o.  and LOTOS Petrobalti SA (the latter holds solely offshore concessions). PGNiG SA, the previous leader, has relinquished as much as seven concessions and now holds only 4 of them. The relinquished concessions are:

  • Kock - Tarkawica in the Lublin and Mazowieckie Provinces,
  • Wiszniów - Tarnoszyn in the Lublin Province,
  • No. 172 in the Mazowieckie and Kujawsko – Pomorskie Province,
  • No. 173 in the Mazowieckie Province,
  • No. 193 in the Mazowieckie Province,
  • Tomaszów Lubelski in the Pokarpackie and Lublin Provinces,
  • Pakosław - Krotoszyn in the Dolnośląskie i Wielkopolskie Provinces.

The total concession area shrank  to 26,300 km2, or 8.5% of Poland's surface, while in 2012-1013 the total area under concessions was 90,000 km2, or almost 30% of Poland's surface.

Concession holders drilled 71 appraisal wells, including 17 directional/horizontal and 54 vertical boreholes, by 3 September 2015. One well – Wysin-2H at the “Stara Kiszewa” Concession, Pomeranian Province – is being drilled by United Oilfield Service for  PGNiG. Three shale gas exploratory wells (Pęclin - OU1 i Rawicz 12 SL-1 and Wysin - 2H) were completed in 2015.

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 9 wells. Special jobs are still to be made in 41 wells. No hydraulic fracture stimulation nor DFIT jobs have been performed in 2015.

In the past years, the number of hydraulic fracture stimulation and DFIT operations was as follows:

  •         2010 - 2 wells fracture stimulated and 1 DFIT,
  •         2011 - 7 wells fracture stimulated,
  •         2012 - 8 wells fracture stimulated and 7 DFIT,
  •         2013 - 4 wells fracture stimulated and 1 DFIT,
  •         2014 - 4 wells fracture stimulated.
