hydraulic gas drainage drilling machineindex

Generally, a hydraulic drilling equipment spread has a smaller footprint than a conventional drilling rig. This is, in part, because hydraulic drilling usually involves smaller hole sizes requiring smaller drill string diameters, smaller OD and lighter BHAs, and smaller mud systems and pumps that require only the circulation rates necessary to clean the hole.

Fracking | What is Fracking? | Shale Oil and Natural Gas | …

Hydraulic fracturing is a proven drilling technology used to extract oil or natural gas from deep underground. Fracking has been safely used in the U.S. since 1947 and on more than 1.7 million wells. Is fracking a threat to public health? No. In fact, there is ample evidence that increased natural gas use — made possible by fracking — has improved public health by dramatically improving ...
