Polskie Górnictwo Naftowe i Gazownictwo (PGNIG) has discovered a tight gas deposit in the Poznań area at the Pniewy-4 well (Wronki licence), which is one of the first discoveries of such unconventional gas accumulations in western Poland.

According to initial estimates, the deposit holds 1-1.5 billion cubic metres of natural gas. The Company is beginning a well production test to determine the deposit parameters, the results of which will help it make decisions on further work related to the development of the Pniewy site.

Geological data verification, more accurate reservoir estimates and planning of further work will take several months.

The Pniewy-4 well was drilled in the period from April to June 2013 to confirm the natural gas accumulation in the examined structure. The tests performed on the Rotliegend formations confirmed saturation of the reservoir with tight gas, and a hydraulic fracturing treatment was performed in late November to obtain commercial gas flows.

Tight gas deposits require larger expenditure throughout the exploration and appraisal phase due to their worse
production parameters. Production of tight gas involves additional technical operations.
