Hydraulically fractured horizontal wells accounted for sixty nine percent of all oil and natural gas wells drilled in the United States, and 83 percent of the whole linear footage drilled, in 2016, the U.S. Power Info Administration reported Tuesday.

Baiji oil refinery - WikipediaThe mix of horizontal drilling and hydraulic fracturing, or fracking, has elevated the rate of current U.S. crude oil, lease condensate and natural gas production in Pennsylvania and different states, the EIA stated.

Hydraulically fractured horizontal wells grew to become the predominant methodology of new U.S. crude oil and natural gas growth in October 2011, when complete footage (in linear ft) surpassed all other drilling and completion strategies.

The mixture of horizontal drilling and hydraulic fracturing has contributed to will increase in crude oil and natural gas manufacturing within the United States, that are anticipated to succeed in record levels in 2018 .

File manufacturing levels are largely attributable to elevated manufacturing of natural fuel and crude oil enabled by the use of fracking techniques in tight rock formations, the EIA said. The agency expects increases in natural gasoline production to be the main contributor to total fossil fuels production development in 2018.

Though horizontal drilling has been used for practically a century, its use as a source of U.S. oil and natural gas production began growing within the early 2000s. The process entails drilling a properly vertically to a certain depth after which bending the trail of the drilling until it extends horizontally.

In 2016, total drilled footage reached almost 13 million ft, about 10.7 million of which had been hydraulically fractured and horizontally drilled, the EIA stated.

Fracked horizontal wells have accounted for most of all new wells drilled and accomplished since late 2014. As of 2016, about 670,000 of the 977,000 producing wells have been hydraulically fractured and horizontally drilled.

Hydraulic fracturing entails forcing a liquid under excessive pressure from a wellbore towards a rock formation until it fractures. The injected fluid comprises a proppant small, solid particles, usually sand or a man-made granular strong of comparable size that wedges open the increasing fractures and allows hydrocarbons akin to crude oil and natural gas to stream more easily.
