The inclusion of unconventional shale gas with conventional gas reserves has caused a sharp increase in estimated recoverable natural gas in Canada. [1] 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. [2]
The US Energy Information Administration estimated in 2013 that there were 573 trillion cubic feet (tcf) of technically recoverable natural gas in Canada. [3]
Sir John A. Macdonald had already maintained in an 1880 Parliamentary debate that the British North America Act of 1867 vested the control of the inland and sea-coast fisheries of Canada in the Dominion Government, who incurred all the expense incidental to their protection. [4]
By virtue of the insertion in 1982 of Section 92A of the BNA Act, "(1) In each province, the legislature may exclusively make laws in relation to (a) exploration for non-renewable natural resources in the province;..." The geographical limits of the jurisdiction of the provinces had been tested by the Supreme Court of Canada in Reference Re: Offshore Mineral Rights, a 1967 case which involved all of the provinces that border on the ocean. [5] The decision of the court was that the Dominion of Canada has authority over the sea and seabed; and this was later reflected by the insertion of Section 92A.
There are three major zones identified in Ontario: [6]
While Ontario in 2010 had 1,200 active oil wells and 1,400 active onshore and offshore natural gas wells, [6] there was no major shale gas production as of early 2011.
In 2012, a campaign against fracking was launched in Ontario. [7]
The Ordovician Utica Shale in Quebec potentially holds 4×10 12 cu ft (110×10 9 m3) at production rates of 1×10 6 cu ft (28,000 m3) per day [8] [9] From 2006 through 2009 24 wells, both vertical and horizontal, were drilled to test the Utica. Positive gas flow test results were reported, although none of the wells were producing at the end of 2009. [10] Gastem, one of the Utica shale producers, has announced plans to explore for Utica Shale gas across the border in New York state. [11]
The Utica shale is a black calcareous shale, from 150 to 700 feet (210 m) thick, with from 3.5% to 5% by weight total organic carbon. The Utica Shale play focuses on an area south of the St. Lawrence River between Montreal and Quebec City. Interest has grown in the region since Denver-based Forest Oil Corp. announced a significant discovery there after testing two vertical wells. Forest Oil said its Quebec assets may hold as much as four trillion cubic feet of gas reserves, and that the Utica shale has similar rock properties to the Barnett shale in Texas.
Forest Oil, which has several junior partners in the region, has drilled both vertical and horizontal wells. Calgary-based Talisman Energy has drilled five vertical Utica wells, and began drilling two horizontal Utica wells in late 2009 with its partner Questerre Energy, which holds under lease more than 1 million gross acres of land in the region. Other companies in the play are Quebec-based Gastem and Calgary-based Canbriam Energy.
The US Energy Information Administration estimated in 2013 that there were 31 trillion cubic feet (tcf) of technically recoverable natural gas in the Utica Shale in Quebec. [3]
On 26 August 2015, CBC reported that the British Columbia regulator was aware of a magnitude 4.4 earthquake which had been caused by Progress Energy, a subsidiary of the Malaysian state-owned enterprise, Petronas. [12]
The Devonian Muskwa Shale of the Horn River Basin in northeast British Columbia is said to contain 6×10 12 cu ft (170×10 9 m3) of recoverable gas. Major leaseholders in the play are EOG Resources and Ovintiv [13]
The government of British Columbia announced lease proceeds for 2008 to be in excess of CDN$2.2 billion, a record high for the province, with the majority of the proceeds coming from shale gas prospects. The British Columbia government has granted royalty credits to companies for drilling and infrastructure development in the area.
The US Energy Information Administration estimated in 2013 that there were 145 trillion cubic feet (tcf) of technically recoverable natural gas in the Muskwa Shale. [3]
The Montney Shale play is in east-central British Columbia. [14] The Montney Formation has a sandy facies in Western Alberta, where oil is produced in the Sturgeon Lakes and Saddle Hills areas. Natural gas is extracted from siltstone reservoir in the Dawson Creek and Pouce Coupe areas and gas rich silty shales occur in the northern and western fringes of the deposit. [15]
The Duvernay Formation is considered the source rock for the Leduc reefs light oil play. Shale gas and condensate is produced from the Duvernay Formation in central Alberta using horizontal drilling and multi-stage hydraulic fracturing. [16]
On 16 June 2015, Andrew Nikiforuk wrote that Chevron Canada had confirmed that "a magnitude 4.4 seismic event was recorded by seismic monitoring arrays operated by Chevron Canada and Natural Resources Canada" in the Duvernay shale near Fox Creek, Alberta. [17] Nikiforuk is a journalist who has followed the Canadian oil and gas industry since the late 1990s. [18]
In 2009, Triangle Petroleum Corporation completed two gas wells in the Horton Bluff Formation, of the Windsor Basin, Nova Scotia. [19]
The US Energy Information Administration estimated in 2013 that there were 3.4 trillion cubic feet (tcf) of technically recoverable natural gas in the Horton Bluff Shale. [3]
New Brunswick oil and gas exploration first began in 1859 in the Moncton sub-basin. [20] The first efforts for commercial production in New Brunswick were in the Stoney Creek oil field, this begun in 1909. [20] [21] As of November 2011, nine companies had 71 different leases to search and explore for shale gas deposits across the province and not just in the southern part of New Brunswick. [22] The province expected in 2011 to receive $21 million in royalties. [20] Between 1990 and 2010, government statistics show 40 natural gas wells and 40 oil wells had been drilled. Another 49 wells had undergone hydraulic fracturing and nine of the wells had been drilled horizontally. [20]
Companies operating in southern New Brunswick also have relatively close access to the Maritimes & Northeast Pipeline, which was built in 1999 to transport natural gas from Sable Island to New England. [20]
Corridor Resources announced in 2010 that it had found more natural gas in place in southern New Brunswick than is available in all of western Canada's proven reserves, and that it had nearly overlooked the gas deposit because it had considered the well a dud at first and it was abandoned for the previous 11 years. [20] Apache Canada was in 2010 one of the first companies that began drilling horizontal wells to tap the Frederick Brook shale deposit. [23]
In June 2011 and in the wake of months of protests by citizens, Natural Resources minister Bruce Northrup unveiled new regulations on exploration that were to force producers to: [24]
Also in June 2011, Grand Chief Harry LaPorte of the Maliseet First Nation worried that the controversial mining process of hydro-fracking should not be allowed in New Brunswick over fears it could harm the water supply: [25]
Hydro-fracking has a very, very good chance to leak into our water system. That's not only our drinking water but it's also our lakes, our rivers, our streams. And the chemicals that they put in, I'm told are very poisonous... My position is just to stop it all: stop it all. Do we need it? Do we need the shale gas? Does other parts of the world need the shale gas? But at what expense are we willing to go through to supply other people with what we have here?
In August 2011, SWN operations in New Brunswick were subject to vandalism, [26] and in November, a teepee was erected by protestors, who were said to number 600, on the front lawn of the legislature in Fredericton. [27] The Conservative New Brunswick government of David Alward at the time refused to put a moratorium on shale gas development in the province; [27] Natural Resources minister Bruce Northrup seemed to be sympathetic to shale gas development in August, but seemed not to have clarified in his own mind the distinction between public and private property. [26]
Also in August 2011, protesters at Stanley, New Brunswick, between Fredericton and Miramichi at the intersection of Route 107 and Route 620, blockaded seismic trucks. Protesters, who were concerned that the seismic testing could lead to hydro-fracking in their communities, came from various communities, such as Penniac, Taymouth, Stanley, Rogersville and several First Nations, and began singing traditional First Nations songs once the Royal Canadian Mounted Police (RCMP) arrived. [28]
In November 2011, the New Brunswick Department of Natural Resources filed a complaint with the RCMP against Windsor Energy Inc. for allegedly violating the Oil and Natural Gas Act. [29] The Calgary-based company was accused of directing a contracted company to conduct geophysical exploration within the boundaries of the town of Sussex, New Brunswick without the town's permission, according to a statement by Natural Resources Minister Bruce Northrup. Under regulation 86–191 of the Oil and Natural Gas Act, a municipality's written permission is required before geophysical activity can be conducted inside the boundaries of an incorporated municipality. Northrup has previously said it is clear Windsor Energy broke the rules and did so intentionally. Its contractor, Seismotion, originally asked for town approval to do tests within the community, and councillors arranged a special meeting in October, just ahead of the company's scheduled arrival, the department found, but when Seismotion crews arrived in Sussex two days ahead of schedule, the company decided not to wait for town consent. [30]
Over the year 2012, SWN Resources increased its leasehold from 1 million hectares to 2.5 million hectares. It named new regions the Marysville Formation, the Cocagne Formation. [31] It appeared that the lower third or quarter of the province had by then been claimed. The province measures in total 7.165 million hectares.
The Elsipogtog First Nation was subject to controversy when it protested with blockades the fracking activity of SWN Resources in 2013. This protest attracted international attention, and was one of the reasons why fracking was a major issue in the 2014 New Brunswick general election.
A week before the 2014 elections, Windsor Energy sued Northrup and the Government because of the statements Northrup made in 2011 to the effect that Windsor violated the province's Oil and Natural Gas Act when it conducted seismic testing in the town of Sussex. Windsor claimed Northrup was libellous when he issued a press release in November of that year, following an incident in which a Windsor subcontractor did seismic tests along Highway 1 inside Sussex town limits. Northrup said Windsor did not have permission to do the tests and had violated the act. The province then filed a complaint with the RCMP. In the statement of claim, Windsor recounts how it was cleared by the RCMP and alleges Northrup's press release was false, misleading and defamatory, and that the negative publicity drove potential investors away from his company. [32] [33] It was not immediately apparent how an apology issued by the company in 2011 to the mayor, councillors and people of Sussex would affect the suit. [29]
On 24 March 2015, the Gallant government appointed a three-member panel to study the hydraulic fracturing process and report back to cabinet within one year on whether the government's conditions for shale gas development can be met. Energy and Mines Minister Donald Arseneault said that the government has a responsibility to consider the controversial method of natural gas extraction as a possible way to create jobs. Gallant appointed Guy Richard, former chief justice of the Court of Queen's Bench, to lead the commission. [34] Richard is the father-in-law of Dominic LeBlanc, a federal MP and Gallant's campaign manager in the 2014 provincial election. [35] The conditions of the government were reported to be: [34]
On 29 May 2015, Richard stepped down as head of the commission, and was replaced by Marc Leger, a career civil servant and former clerk of New Brunswick's Executive Council. The other two members are John McLaughlin and Cheryl Robertson. [36]
New Brunswick has an estimated 80 trillion cubic feet of gas locked more than a kilometre beneath the ground in the Frederick Brook Shale formation in the southern part of the province. This formation, which was created more than 300 million years ago, runs along the south shore of New Brunswick from the Hampton area all the way to Sackville. [22] [37]
In June 2010, Apache Canada began drilling a horizontal well to tap the Lower Carboniferous Frederick Brook Shale, near Sussex, New Brunswick. Apache is in a joint venture with Halifax-based Corridor Resources Inc., which has extensive leasehold in the province. Corridor has drilled two vertical wells that tested gas from the Frederick Brook. [38]
In 2013, Corridor Resources proposed a phased Environmental Impact Assessment (EIA) for the expansion of the McCully Field in 2013 and 2014. Phase 1 was to expand the F-67 well pad by October 2013 and phase 2 began exploration and development by November 2014. [39]
In 2015, it was revealed that Contact Exploration Inc., had plans to do oil and gas exploration in Salem, near Hillsborough, New Brunswick in the marshlands of the Petitcodiac River. The proposed Phased EIA was under review by the Government of New Brunswick. [40]
Natural gas is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) in addition to various smaller amounts of other higher alkanes. Traces of carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Methane is colorless and odorless, and the second largest greenhouse gas contributor to global climate change after carbon dioxide. Because natural gas is odorless, odorizers such as mercaptan are commonly added to it for safety so that leaks can be readily detected.
Ovintiv Inc. is an American petroleum company based in Denver. The company was formed in 2020 through a restructuring of its Canadian predecessor, Encana.
The Elsipogtog First Nation, formerly called the Big Cove Band, is a Miꞌkmaq First Nations band government in New Brunswick, Canada. The First Nation's territory comprises Richibucto Reserve #15, lying 8 kilometres (5.0 mi) southwest of Five Rivers, New Brunswick on the Richibucto River off of Route 116. It also comprises Soegao Reserve #35, lying 5 kilometres (3.1 mi) west of Moncton, New Brunswick. As of April 2023, the registered Elsipogtog population is 3,574, with 2,736 living on reservations and 798 living off reservations.
Expand Energy Corporation is a natural gas exploration and production company headquartered in Oklahoma City. It was previously known as Chesapeake Energy Corporation.
The Barnett Shale is a geological formation located in the Bend Arch-Fort Worth Basin. It consists of sedimentary rocks dating from the Mississippian period in Texas. The formation underlies the city of Fort Worth and underlies 5,000 mi2 (13,000 km2) and at least 17 counties.
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 Bakken Formation is a rock unit from the Late Devonian to Early Mississippian age occupying about 200,000 square miles (520,000 km2) of the subsurface of the Williston Basin, underlying parts of Montana, North Dakota, Saskatchewan and Manitoba. The formation was initially described by geologist J. W. Nordquist in 1953. The formation is entirely in the subsurface, and has no surface outcrop. It is named after Henry O. Bakken (1901–1982), a farmer in Tioga, North Dakota, who owned the land where the formation was initially discovered while drilling for oil.
Shale gas in the United States is an available source of unconventional natural gas. Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas. Largely due to shale gas discoveries, estimated reserves of natural gas in the United States in 2008 were 35% higher than in 2006.
The Utica Shale is a stratigraphical unit of Upper Ordovician age in the Appalachian Basin. It underlies much of the northeastern United States and adjacent parts of Canada.
Fracking is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants hold the fractures open.
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.
Southwestern Energy Company was a natural gas exploration and production company organized in Delaware and headquartered in Spring, Texas. In October 2024, the company merged into Expand Energy.
Range Resources Corporation is a natural gas exploration and production company, the headquartered is in Fort Worth, Texas. It operates in the Marcellus Formation, where it is the largest land owners.
The Vaca Muerta Formation, commonly known as Vaca Muerta, is a geologic formation of Late Jurassic to Early Cretaceous age, located in the Neuquén Basin in northern Patagonia, Argentina. It is well known as the host rock for major deposits of shale oil and shale gas.
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.
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.
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 Marcellus natural gas trend is a large geographic area of prolific shale gas extraction from the Marcellus Shale or Marcellus Formation, of Devonian age, in the eastern United States. The shale play encompasses 104,000 square miles and stretches across Pennsylvania and West Virginia, and into eastern Ohio and western New York. In 2012, it was the largest source of natural gas in the United States, and production was still growing rapidly in 2013. The natural gas is trapped in low-permeability shale, and requires the well completion method of hydraulic fracturing to allow the gas to flow to the well bore. The surge in drilling activity in the Marcellus Shale since 2008 has generated both economic benefits and considerable controversy.
Fracking in Canada was first used in Alberta in 1953 to extract hydrocarbons from the giant Pembina oil field, the biggest conventional oil field in Alberta, which would have produced very little oil without fracturing. Since then, over 170,000 oil and gas wells have been fractured in Western Canada. Fracking is a process that stimulates natural gas or oil in wellbores to flow more easily by subjecting hydrocarbon reservoirs to pressure through the injection of fluids or gas at depth causing the rock to fracture or to widen existing cracks.
American Energy Partners, LP, also known as AELP, was an American natural gas and oil company founded in April 2013 by Aubrey K. McClendon. The company managed affiliates responsible for natural shale gas and oil production and exploration in the United States, as well as management of assets, minerals, royalties and non-operated properties. It was headquartered in Oklahoma City, Oklahoma, and employed over 450 people as of August 2015. AELP announced on May 18, 2016, two months after McClendon's death, that it would end operations and close by the end of summer 2016.
