House Mountain

Covering 21,320 hectares 20 kilometres south of Lesser Slave Lake, the House Mountain Field is a perfect example of Apache Canada’s use of new technology in the rejuvenation of a field once thought to be near the end of its lifespan.

Upon acquiring House Mountain from Shell Canada Ltd. in 1999, Apache Canada worked to expand the original 1960s-era development, adding 7.5 MMBbls of production. Beyond ensuring high production, the majority of wells in the project have been granted Good Production Practice status, meaning that they are also operated to optimize conservation and environmental stewardship.

House Mountain is a mature project that is closely linked both economically and historically to nearby communities and First Nations, where Apache Canada Ltd. is a proud sponsor of many community initiatives.

Recent advancements in drilling and production technologies have allowed Apache Canada Ltd. to rejuvenate the House Mountain wells, enhancing production while reducing surface footprint and CO2 emissions.  New wells drilled in the winter of 2008, 2009 and 2010 were an overwhelming success, proving the enduring potential of the House Mountain field and extending the life of the project for years to come.


The Kaybob project develops the Montney and Bluesky formations in central Alberta, northwest of Edmonton.
Historically, Kaybob has accessed deep gas formations; however, recent developments in horizontal drilling technology have enabled access to significant tight gas formations, increasing production while reducing environmental impact.

Development continues at Kaybob and Apache is confident the project will be a site of continued growth well into the future.  This expansion will not only enhance Kaybob’s production, but also strengthen its relationship with neighbouring communities, First Nations and the provincial government.


The Leduc field, located in central Alberta about 10 minutes south of Edmonton, has excellent potential for development.  Leduc is a mature oilfield boasting low-cost production and a good response to enhanced oil recovery techniques. 

Located among rural acreages and farm land, the success of the Leduc field demonstrates the strength of both Apache’s work to limit its environmental footprint and efforts put into cultivating healthy relationships with its neighbours.


Apache acquired its 100-percent working interest in the Noel area from BP in October 2010.

Noel is also the first full gas field development in Canada to apply a solar photo-voltaic system where solar electricity is generated on site and stored in batteries to help provide a permanent energy supply. A thermal electric generator is used when there is reduced sunlight for more than a week.

Carbon reductions at Noel involve a near-zero emissions well site design using solar energy and electrifying compressors where 84 per cent of the power is hydro-generated.

By drilling long-reach, open-hole horizontal wells at depths exceeding 2,200 metres to produce the tight gas formation, the potential well count was significantly reduced. Drilling multiple wells on a single site has also decreased the number of well pads to 85, minimizing the amount of land disturbed, enhancing economics and addressing stakeholder concerns by helping limit traffic, noise and visual impacts.

With an 85-percent reduction in greenhouse gas (GHGs) and 70 per cent reduction in surface land use, Noel has set a new industry benchmark for responsible and balanced resource development.

On March 15, 2010, the Noel Major Project received the President’s Award from the Canadian Association of Petroleum Producers (CAPP). It also earned the 2010 Steward of Excellence Award and the Best Practice Award at the 2009 World Gas Conference.


The Provost field covers roughly 600,000 acres near Coronation in east-central Alberta. Provost is a mature asset producing 55 million cubic feet of natural gas and 2,450 barrels of oil daily. Though well-developed with extensive infrastructure, Provost remains in the primary phase of oil production, meaning that it will remain a valuable and productive property for the foreseeable future.

Virginia Hills

The Virginia Hills project is located in northwestern Alberta near Swan Hills. Initially envisioned as a gas field during its development in the early 1970s, recent development has allowed Virginia Hills to produce oil from the Permian Belloy Sandstone. This dual production focus permits Virginia Hills to access estimated reserves of 3.2 million barrels of oil and 43 billion cubic feet of gas.


The Wapiti field is located in in western Alberta, just south/southwest of the city of Grande Prairie, where Apache’s operations center is located.

Production comes from 12 Cretaceous-era formations, producing oil, natural gas liquids and sweet natural gas, this vertically stacked production comes from an Apache land base of 116,480 acres. This extraordinary diversity of products, acreage and producing formations, creates many new development opportunities enabled by both new and established technologies. Apache operations are located in forested lands that have seen five decades of oil and gas exploration and development.

West 5

The West 5 operating area in west –central Alberta extends north from Sundre through James River, Stauffer and Willesden Green to Buck Lake. Accessing the Glauconite, Cardium, Viking, Rock Creek and Ellerslie formations, West 5’s wells produce the equivalent of 21,742 barrels of oil every day. In addition to these oil-producing wells, West 5 is home to gas and oil facilities, and employs a total of 70 people from the neighbouring communities.


The Zama pilot project uses a novel enhanced oil recovery method to produce oil from what were once thought to be exhausted wells. Located near Trout Lake in Northern Alberta, Zama accesses the Keg River Basin, a collection of more than 800 pinnacle reefs. Due to previous development, these formations were no longer productive using traditional methods. In 2004, Apache selected one such depleted pool, then used for waste gas disposal, and by modifying the flow of gases was able to once again produce oil from it.
