Giant energy companies like Chevron have found Poland to be a new potential market for shale gas. In order to release the gas from the stone, highly pressurized water enriched with chemicals and quartz is injected into the borehole. The process is called "fracking." Here, a drilling rig is shown near the village of Lesniowice in southeastern Poland.
