Texas – Oil – fracking – Permian Basin

According to the Texas Railroad Commission, more than 7,000 oil fields now dot the Permian Basin, and recent increased use of enhanced-recovery practices (like like hydraulic fracturing, also known as fracking) has resulted in “a substantial impact on U.S. oil production.” In the meantime, a team of researchers from Southern Methodist University (SMU) in Dallas, Texas, has made… Continue reading Texas – Oil – fracking – Permian Basin

Fracking and Earthquakes – West Texas

New research links a rise in seismic activity in West Texas with increased oil and gas development over the past 20 years and, in particular, the past decade.   The study, published 4 November and conducted by the University of Texas (UT) as well as several other universities, leverages old, unmined data to track seismic activity… Continue reading Fracking and Earthquakes – West Texas

Hidroliese breking – Fracking

Groot hidroliese masjinerie word gebruik om diep in die aarde te boor voordat 'n hoëdruk watermengsel op die rots gerig word om die gas binne te laat. Water, sand en chemikalieë word teen hoë druk in die rots ingespuit, waardeur die gas na die kop van die put kan vloei.   Hidrouliese breuk is 'n wel bevorderingstegniek… Continue reading Hidroliese breking – Fracking
