CHEVRON will collaborate with Polish state-controlled oil and gas company Polskie Górnictwo Naftowe i Gazownictwo (PGNiG) in shale exploration in Poland’s south east.

The companies will work together in appraising shale gas deposits in four exploration licence areas in Poland’s south east – two owned by PGNiG (Tomaszów Lubelski and Wiszniów-Tarnoszyn) and two belonging to Chevron (Zwierzyniec and Grabowiec).

The detailed scope and schedule of exploration work will be determined by a Joint Technical Committee appointed by both parties, with at least one exploration well to be drilled, PGNiG said.

The two companies will also share geological data and the experience they have gathered as part of their respective exploration activities.

PGNiG management board president Mariusz Zawisza said the collaboration would see PGNiG draw on extensive shale gas exploration experience, and was part of a new policy of openness to other shale gas explorers.

“We hope that this partnership will be beneficial to both parties by allowing us to optimise the costs and improve the effectiveness of our exploration efforts,” he said.

The news came as PGNiG started drilling the exploratory Tępcz 1 vertical borehole, in Luzino, within the Wejherowo licence area, to investigate the hydrocarbon potential of shale deposits.

With a target depth of 3,380 metres, the work is expected to continue for around two months, with drilling work performed by Exalo, a PGNiG Group company, using the MASS 6000E rig.

PNGiG is also carrying out 3D seismic work over the Kochanowo-Tępcz-Cząstkowo area which will help define the company’s 2015 drilling campaign area.
