2021-3-14 The oil shale industry is an industry of mining and processing of oil shale—a fine-grained sedimentary rock, containing significant amounts of kerogen (a solid mixture of organic chemical compounds), from which liquid hydrocarbons can be manufactured. The industry has developed in Brazil, China, Estonia and to some extent in Germany and Russia. Several other countries are currently
In 2014, a muscular, middle-aged Ohio man named Peter took a job trucking waste for the oil-and-gas industry. The hours were long — he was out the door by 3 a.m. every morning and not home until
2021-3-18 Petroleum (/ p ə ˈ t r oʊ l i ə m /), also known as crude oil and oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is commonly refined into various types of fuels.Components of petroleum are separated using a technique called fractional distillation, i.e. separation of a liquid mixture into fractions differing in boiling
2021-3-18 Hydraulic fracturing, also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing, is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore
2018-6-20 Plan, direct, or coordinate the operations of public or private sector organizations. Duties and responsibilities include formulating policies, managing daily operations, and planning the use of materials and human resources, but are too diverse and general in nature to be classified in any one functional area of management or administration, such as personnel, purchasing, or administrative
Explore a Fracking Operation Virtually. Modern oil and gas extraction no longer involves just a well, pump, and tank. The process can be so overwhelmingly complex that in lieu of taking a tour in person, it helps to explore each stage through photos.
2 天前 Resource extraction, including oil and gas drilling, timber harvesting, etc., is generally not permitted on these lands. The NPS requires oil and gas operators to obtain approval of their extraction plans before oil and gas activity can occur. If a plan is approved and the operator gets a reclamation bond, drilling can occur. Federal laws
Unconventional oil and natural gas play a key role in our nation's clean energy future. The U.S. has vast reserves of such resources that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies.. These technologies enable greater access to oil and natural gas in shale formations.
2 天前 Shale gas and oil is found in a large number of small pockets and a different technique is needed to get them to the surface, hydraulic fracturing. This involves drilling down vertically 2 km or more below the surface before gradually turning horizontal and continuing drilling for as much as another 3 km.
2019-12-28 Completion Components . Oil and gas well completions require not only a good well design, but also many components and different types of equipment to ensure the safe and efficient flow of oil
