| 9:00a | Техас: последствия нефтедобычи (до массового внедрения горизонтального бурения и гидроразрыва) June 15, 2016 Texas: Giant unstable sinkholes are growing, could be on verge of catastrophic collapse http://www.ibtimes.co.uk/texas-giant-un Two giant sinkholes in Texas are getting bigger and are at risk of collapsing – the effects of which could be "catastrophic", scientists have warned. The sinkholes, found in the towns of Wink and Kermit, have been observed via satellite, and images indicate major changes could be underway. The two sinkholes are currently a mile apart. The first one – Wink 1 - appeared in 1980, while the second – Wink 2 – opened up in 2002. They were caused by intense gas and oil extraction in the region from the 1920s to the 1960s. Wink 1 is currently 110m across, while Wink 2 can reach up to 270m.

Наиболее близкие к поверхности месторождения, возможно даже обнаруженные по выходу на поверхность нефти. ii/ Вероятно было поддержание пластового давления путем закачки воды в пласты и вероятные минигидроразрывы пластов iii/ Современные гидроразрывы на много более мощные и проводятся многократно, поэтому возможны различные ситуации.
