Overview
Petrobank Energy and Resources was a Canadian oil and gas company headquartered in Calgary. Its activities combined conventional exploration and production with the development of technologies intended to recover heavy oil and oil-sands bitumen in situ. The company operated through several business units and subsidiaries, including PetroBakken Energy in Canada, Petrominerales in Colombia and Peru, HBU in heavy oil, and Archon Technologies, which developed and commercialized the company's THAI and CAPRI extraction technologies. The company adopted the name Petrobank Energy and Resources Ltd. in 1986, having previously been known as Petrobank Energy Resources Ltd. During the period described in the available reference material, its portfolio included Canadian light-oil and natural-gas assets, international exploration and production interests, and a large contingent heavy-oil resource base. PetroBakken focused on Canadian light oil, including the Bakken and Cardium plays, as well as other Canadian resource areas. Petrominerales held exploration and production interests in Colombia and Peru, including assets in the Llanos and Magdalena Valley basins in Colombia and exploration acreage in Peru. HBU and the related Whitesands operations focused on heavy oil and bitumen resources in Western Canada. Petrobank's principal technological proposition was Toe-to-Heel Air Injection, commonly abbreviated THAI. The process combines a vertical air-injection well with a horizontal production well. Air is injected into the reservoir to sustain a combustion front that moves along the horizontal well, heating and partially upgrading viscous heavy oil so that it can flow toward the production well. Petrobank presented THAI as an alternative to steam-assisted gravity drainage because it used air rather than large volumes of injected steam and could potentially reduce water requirements. The company also associated CAPRI with the process as an in-reservoir upgrading configuration. The technology was tested or applied at a number of heavy-oil locations, including Kerrobert, Saskatchewan, and projects in Alberta. Petrobank expanded its Canadian position through the 2009 acquisition of Tristar Oil & Gas Ltd. The acquired Canadian operations were combined with Petrobank's existing Canadian assets to create PetroBakken Energy, in which Petrobank retained a majority interest. Petrobank also adjusted its ownership of Petrominerales and subsequently reorganized that relationship. The reference material states that the Petrominerales separation was completed on December 31, 2010, with Petrobank shareholders receiving shares in the newly independent Petrominerales entity rather than a cash payment. In heavy oil, Petrobank acquired interests associated with the Kerrobert and Dawson projects in 2010 and obtained Alberta approval to produce oil-sands bitumen at Dawson using its fireflooding approach. The company described the Whitesands resource as potentially containing between 1.8 and 2.6 billion barrels of oil, although such figures represented estimated resources rather than established production or sales. By the first half of 2010, Petrobank's reported business was considerably larger than in the comparable period of 2009, with growth attributed substantially to PetroBakken and Petrominerales. Only PetroBakken was identified in the source material as producing natural gas. The available references do not establish the company's later corporate status, final ownership, or current operating activity.
History
Petrobank Energy and Resources developed as a Canadian oil and gas enterprise with a base in Calgary. In 1986, the company changed its name from Petrobank Energy Resources Ltd. to Petrobank Energy and Resources Ltd. Its business eventually extended beyond conventional oil exploration and production into international operations and heavy-oil technology. The company's operating structure included four principal areas described in the available reference material. PetroBakken Energy was a majority-owned Canadian subsidiary focused on light oil and related production, including the Bakken and Cardium areas. Petrominerales operated internationally, with interests in Colombia and Peru. HBU was Petrobank's wholly owned heavy-oil business, established in 2006. Archon Technologies served as the technology arm associated with THAI and CAPRI, Petrobank's proprietary heavy-oil recovery and upgrading processes. Petrobank's Canadian conventional portfolio included light crude production in southeastern Saskatchewan and resource positions in British Columbia's Montney and Horn River Basin areas. PetroBakken was also identified as the only Petrobank unit producing natural gas in the supplied material. Petrominerales held Colombian interests covering numerous exploration blocks and approximately two million acres, with activity in the Llanos Basin, the Magdalena Valley Basin, and the Putumayo Basin. Its Colombian portfolio included the Corcel and Guatiquia areas, cooperation with Ecopetrol at Neiva, and the Orito discovery. In Peru, Petrominerales held exploration blocks in the Ucayali and Titicaca basins. A central part of Petrobank's identity was its attempt to commercialize alternative heavy-oil recovery methods. Its THAI process used a vertical air-injection well and a horizontal production well. After ignition, an underground combustion front advanced along the horizontal well, heating heavy oil and reducing its viscosity. The company argued that the process could require substantially less water than steam-based methods such as steam-assisted gravity drainage. CAPRI was associated with additional in-reservoir upgrading of the produced heavy oil. Testing and development were reported at Kerrobert, Sutton, Whitesands, May River, Dawson, and Conklin, among other locations. The company enlarged its Canadian production platform in August 2009 through the purchase of Tristar Oil & Gas Ltd. The transaction was reported at approximately C$2.24 billion. Petrobank combined Tristar's Canadian operations with its own Canadian assets and established PetroBakken Energy, retaining a majority stake. In the same broad period, Petrobank reduced its interest in Petrominerales. The source material records a reduction from 76.9% to 66.8% in May 2009. Heavy-oil development became more prominent in 2010. Petrobank acquired interests connected with the Kerrobert and Dawson projects, advanced work at Kerrobert, and began expansion and construction activity there. It also acquired a 50% interest in Dawson from Shell Canada and received Alberta approval to produce bitumen at the site using fireflooding. These projects were intended to demonstrate the company's heavy-oil technology while expanding its resource base. The supplied reference describes strong year-over-year growth in the first half of 2010. Revenue was approximately C$1.1 billion compared with C$415 million in the first half of 2009, while conventional oil production rose from about 42.5 thousand barrels per day to 83.9 thousand barrels per day. The same reference attributes much of the increase to PetroBakken and Petrominerales. These figures are historical reported operating data and do not establish present-day performance. Petrobank's relationship with Petrominerales was reorganized at the end of 2010. The supplied material states that Petrominerales became independent on December 31, 2010, with Petrobank shareholders receiving 0.614 shares of the new Petrominerales for each Petrobank share, while pre-reorganization Petrominerales shareholders received one share of the new company. The available material does not document the company's subsequent corporate history sufficiently to determine its final status, successor, or current brand use.

Products and positioning
An integrated oil and gas company distinguished by its combination of conventional production assets, international exploration interests, and proprietary heavy-oil recovery technology.
Heavy-oil recovery technology
THAI
Toe-to-Heel Air Injection is an in-situ combustion process designed for viscous heavy oil and bitumen. It uses a vertical air-injection well positioned near the toe of a horizontal production well. Air sustains a combustion front that moves toward the heel, heating and partially upgrading oil so it can flow toward the production well. Petrobank promoted THAI as a lower-water alternative to steam-intensive recovery methods.
In-reservoir oil upgrading technology
CAPRI
CAPRI was associated with Petrobank's THAI technology as an in-reservoir upgrading configuration. Its purpose was to improve the quality and mobility of heavy oil during underground recovery by promoting upgrading reactions around the production well. The available reference material identifies Archon Technologies as the technology unit connected with THAI and CAPRI.
Oil and gas production
Canadian light-oil production
Through PetroBakken, Petrobank held Canadian light-oil operations in areas including the Bakken and Cardium formations and southeastern Saskatchewan. The business also included Canadian resource positions in the Montney and Horn River Basin areas. The reference material identifies PetroBakken as the Petrobank unit that produced natural gas.
Oil-sands and heavy-oil production
Heavy-oil and bitumen projects
