Sentences with phrase «horizontal oil and gas wells»

The ability to drill horizontal oil and gas wells and to «frack» shale by injecting pressurized sand and chemicals into the rock has enabled a huge boom in natural - gas production over the past decade.

Not exact matches

The pace of oil and gas production gains has consistently surprised forecasters since horizontal drilling and hydraulic fracturing, better known as «fracking», were pioneered in U.S. shale rock formations about ten years ago.

PDC has successfully drilled the equivalent of 20 - 22 horizontal wells per 640 - acre section, to more efficiently capture the large oil and gas resources in - place in the Niobrara and Codell formations, which contain over 300 feet of combined reservoir rock.

Paterson noted the bill, which was passed by both the Senate and Assembly during the recent extraordinary session (although it was not on the governor's agenda), goes well beyond horizontal hydraulic fracturing and effectively would result in a moratorium on all new oil and gas well drilling.

He said that an amendment was already planned that would extend the ban to include wastewater from vertically drilled oil and gas wells (which is being used elsewhere in the state for deicing roads), as well as those using horizontal fracking techniques.

Until now, estimates of shale gas production have primarily relied on models established for conventional oil and gas wells, which behave differently from the horizontal wells in gas - rich shales.

Modern hydraulic fracturing combined with horizontal drilling allows multiple wells to be drilled from one spot, reducing the size of the drilling area above ground by as much as 90 percent.4 Fracking is the key to unlocking vast U.S. shale resources, freeing up oil and natural gas that previously was inaccessible while protecting groundwater supplies and the environment.

Historically, fracturing in California has been used in vertical wells — not in combination with the horizontal drilling techniques that have wrested oil from North Dakota's Bakken and natural gas from the Barnett shale of Texas or Marcellus shale in Pennsylvania.

The Federal Court of Canada has ruled against a Calgary - based oil and gas services company ensuring there is no monopoly on a fracturing technology used in horizontal drilling and well completion systems in the sector.
