tight gas

Most of the gas-producing formations are considered tight gas, having low natural permeability.

The transaction included East Resources' tight gas fields.

The petroleum industry turned to the new massive hydraulic fracturing technique as the way to recover tight gas.

The Gas Plus regime applies to new discoveries and to "tight gas" fields.

Tight gas is gas in low-permeability rock.

Tight gas reservoirs are generally defined as having less than 0.1 milli darcy (mD) permeability.

Mr. Bell worked for Amoco as a production engineer on drilling and completing tight gas wells.

There is currently a boom in sales of tight gas and shale gas from the USA.

Projects include investigations into superconductivity, lean burn engines, biofuels, offshore wind power, and tight gas deposits.

They have criticized him for not bucking the industry's lobbying against tighter gas mileage requirements, which have not been increased much since the 1980's.

This increase in stimulation zones has been the key to unlocking tight gas formations as the zones can be individually treated to increase overall production.

Tight gas is natural gas produced from reservoir rocks with such low permeability that massive hydraulic fracturing is necessary to produce the well at economic rates.

Drayton Valley's Cardium and Liquids Rich Tight Gas are a couple of large resource fields in the country.

The natural gas industry is extracting an increasing quantity of gas from challenging resource types: sour gas, tight gas, shale gas, and coalbed methane.

Gas (Tight Gas, Shale Gas, Coalbed Methane)

Gas permeability of reservoir rock and source rock is important in petroleum engineering, when considering the optimal extraction of shale gas, tight gas, or coalbed methane.

This mixture is injected at high pressure into faults to release petroleum, natural gas (including shale gas, tight gas, and coal seam gas), or other substances for extraction.

Now a substantial small car, the Civic remains a leader in high mileage and low emissions, and the redesigned 2001 model is arriving at a time of tight gas supplies and high prices.

Central America continues with its biofuels and unconventional (tight gas, shale gas and coalbed methane) programmes, releasing it from ultra deep and deep water drilling in the Gulf of Mexico.

Innovation in the area of hydraulic fracturing has opened huge reserve potential in the area of nonconventional gas with reservoirs of various geologic types including shales, tight gas and coal beds.

Potential tight gas resources in a frontier province, Jurassic through Tertiary strata beneath the Brooks Range foothills, Arctic Alaska U.S. Geological Survey Open-file Report 2006-1172.

Tight gas supplies in the United States pose a threat to economic growth, said Alan Greenspan, chairman of the Federal Reserve, which lowered interest rates today in response to general weakness in the American economy.

Madam President, Commissioner, I am pleased that the European Parliament has managed to initiate a debate on the possibility of exploiting gas from non-conventional energy sources, such as shale gas, tight gas and coalbed methane.

Injected volumes tend to be much smaller than those of either tight gas wells or shale gas wells; a 2004 EPA study found a median injected volume of 57,500 gallons for coalbed methane wells.

Despite successfully demonstrating non-combat uses for nuclear explosives, (i.e., for rock blasting and stimulation of tight gas), negative impacts from Project Plowshare's 27 nuclear projects led to the program's termination in 1977, due in large part to public opposition.
