Gaz ziemny o największym w Polsce ciśnieniu złożowym
Abstract
GAS WITH THE HIGHEST DEPOSIT PRESSURE IN POLAND
Summary
The borehole Unisław IG 1, made at the contact of the Warsaw and Pomeranian basins by the Geological Institute, revealed a new gas-bearing zone in the Polish Lowlands. The gas-bearing horizon, encountered in rocks tentatively assigned to the Carboniferous - Lower Permian (depth 4549.5-4561.0 m), is characterized by anomalously high deposit pressure: 823 at (807 • 103 hPa) - the highest in Poland and one of the highest in Europe.
The lack of high-pressure exploitational head made it necessary to estimate gas output with reference to the intensity of gas appearance, rapid vertical increase of pressure curve up to 95% of its value, and fairly good porosity of rocks. The estimations showed that the output is medium-high as for commercial gas occurrences and chemical composition of the gas from the borehole Unisław IG 1 was found to be fairly advantageous.
