Coalbed methane, coalbed gas, or coal seam gas (CSG) is a form of natural gas extracted from coal beds. In recent decades it has become an important source of energy in United States, Canada, Australia, and other countries.
Consol Energy Inc. is an American energy company with interests in coal headquartered in the suburb of Cecil Township, in the Southpointe complex, just outside Pittsburgh, Pennsylvania. In 2017, Consol formed two separate entities: CNX Resources Corporation and CONSOL Energy Inc. While CNX Resources Corp. focuses on natural gas, spin-off Consol Mining Corporation, now Consol Energy Inc. focuses on coal. In 2010, Consol was the leading producer of high-BTU bituminous coal in the United States and the U.S.'s largest underground coal mining company. The company employs more than 1,600 people.
China National Coal Group Co., Ltd., known as China Coal Group, is a Chinese coal mining conglomerate that was supervised by the State-owned Assets Supervision and Administration Commission (SASAC) of the State Council. It was the second largest state-owned coal mining enterprise in the mainland China, and the third largest in the world, just after Shenhua Group in 2008, according to a website quoting Xinhua News Agency. It is engaged in coal production and sales, coal chemicals, coal mining equipment manufacturing, coal mine design and related engineering services.
Shale gas is an unconventional natural gas that is found trapped within shale formations. Since the 1990s a combination of horizontal drilling and hydraulic fracturing has made large volumes of shale gas more economical to produce, and some analysts expect that shale gas will greatly expand worldwide energy supply.
The Sacred Headwaters is a large subalpine drainage basin centred around Klappan Mountain of the Klappan Range in northern British Columbia. It is the source of three wild salmon rivers: the Skeena River, Nass River, and Stikine River. It is also referred to as the Klappan Valley, although the Klappan—a tributary of the Stikine River—is only one of the area's watersheds. Local Tahltan people call the area Klabona, which is loosely translated as "headwaters".
The Klappan Coalbed Methane Project is a gas project owned by Shell Canada that looks to develop the coalbed methane from an area in northern British Columbia, near the source of three rivers: the Skeena River, Nass River, and Stikine River, and also the namesake Klappan River. The area is known in environmental politics and native lore as the Sacred Headwaters or Kablona. The project is the source of controversy and is opposed by First Nations groups and non-governmental organizations. If developed, the project will include a network of gas wells connected by roads and pipelines, as well as a pipeline to deliver the gas to market.
Questerre Energy Corporation (QEC) is an international energy exploration company headquartered in Calgary, Canada, and listed on the Toronto Stock Exchange and the Oslo Stock Exchange. It holds the largest acreage position in the Utica Shale in the Saint Lawrence Lowlands. Questerre also have operations in Saskatchewan and in the Montney Formation in Alberta.
The inclusion of unconventional shale gas with conventional gas reserves has caused a sharp increase in estimated recoverable natural gas in Canada. Until the 1990s success of hydraulic fracturing in the Barnett Shales of north Texas, shale gas was classed as "unconventional reserves" and was considered too expensive to recover. There are a number of prospective shale gas deposits in various stages of exploration and exploitation across the country, from British Columbia to Nova Scotia.
Shale gas is an unconventional natural gas produced from shale, a type of sedimentary rock. Shale gas has become an increasingly important source of natural gas in the United States over the past decade, and interest has spread to potential gas shales in Canada, Europe, Asia, and Australia. One analyst expects shale gas to supply as much as half the natural gas production in North America by 2020.
Fracking in the United Kingdom started in the late 1970s with fracturing of the conventional oil and gas fields near the North Sea. It was used in about 200 British onshore oil and gas wells from the early 1980s. The technique attracted attention after licences use were awarded for onshore shale gas exploration in 2008. The topic received considerable public debate on environmental grounds, with a 2019 high court ruling ultimately banning the process. The two remaining high-volume fracturing wells were supposed to be plugged and decommissioned in 2022.
San Leon Energy plc is an independent oil and gas exploration company and is Europe's leading shale gas company by acreage. San Leon has built up a portfolio of assets located in Poland, Morocco, Western Sahara, Albania, Ireland, Spain and Italy. The company's portfolio across these geographies is made up of both conventional exploration and shale assets.
Fracking has become a contentious environmental and health issue with Tunisia and France banning the practice and a de facto moratorium in place in Quebec (Canada), and some of the states of the US.
Cuadrilla Resources is an oil and gas exploration and production company founded in 2007. It is headquartered in Bamber Bridge, Lancashire, and has operations in the United Kingdom. The company intend to develop shale gas in the UK by using hydraulic fracturing. Its chairman is Roy Franklin, who is also deputy chairman of Equinor. Its chief executive is Francis Egan.
There are many exemptions for fracking under United States federal law: the oil and gas industries are exempt or excluded from certain sections of a number of the major federal environmental laws. These laws range from protecting clean water and air, to preventing the release of toxic substances and chemicals into the environment: the Clean Air Act, Clean Water Act, Safe Drinking Water Act, National Environmental Policy Act, Resource Conservation and Recovery Act, Emergency Planning and Community Right-to-Know Act, and the Comprehensive Environmental Response, Compensation, and Liability Act, commonly known as Superfund.
Shale gas in the United Kingdom has attracted increasing attention since 2007, when unconventional onshore shale gas production was proposed. The first shale gas well in England was drilled in 1875. As of 2013 a number of wells had been drilled, and favourable tax treatment had been offered to shale gas producers.
The Balcombe drilling protest occurred when test drilling and possible fracking for petroleum were proposed in 2012 near Balcombe, a village in West Sussex England. Local residents protested and anti-fracking environmentalists in the UK made it a focus of attention. The drill pad is located in a wooded area known as Lower Stumble Wood.
The 2017 production of coalbed methane in the United States was 0.98 trillion cubic feet (TCF), 3.6 percent of all US dry gas production that year. The 2017 production was down from the peak of 1.97 TCF in 2008. Most coalbed methane production came from the Rocky Mountain states of Colorado, Wyoming, and New Mexico.
Great Eastern Energy Corporation Limited is a Coalbed methane (CBM) production company, located in Asansol district of West Bengal. With two CBM blocks, one in Raniganj, West Bengal, and the other in Mannargudi, Tamil Nadu. Great Eastern Energy Corporation has played an important role in providing methane gas. The wells dug in the respective blocks are well connected with gas gathering stations and the gas is fed into its dedicated steel pipeline network to maintain the supply.
Natural gas was the United States' largest source of energy production in 2016, representing 33 percent of all energy produced in the country. Natural gas has been the largest source of electrical generation in the United States since July 2015.
Unconventional reservoirs, or unconventional resources are accumulations where oil and gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialised measures for evaluation and extraction.
