Petrobank was an oil exploration, development, and production company based in Calgary, Canada. It operates through 4 units/subsidiaries, PetroBakken Energy (58% owned subsidiary)〔(【引用サイトリンク】title=Petrobank Reports Q1 2010 Net Income of $82.5 Million And Provides Progress Update For Heavy Oil Business Unit )〕 in Canada, ''Petrominerales Ltd'' (was 65% owned until December 31, 2010 when both company's parted ways through a reorganization) in Peru and Colombia, HBU (100% owned subsidiary started in 2006) in the heavy crude oil business, and its technology unit Archon Technologies Ltd (THAI and CAPRI). In 1986 the company changed its name from Petrobank Energy Resources Ltd. to Petrobank Energy and Resources Ltd.〔(【引用サイトリンク】title=petrobank energy and resources )〕 Though it has a significant resource base its ten patents for heavy oil extracting technology are becoming increasingly valuable to the company.〔(【引用サイトリンク】title=Petrobank's THAI Technology Expands Exploitable Bitumen In Place )〕 In December 2010 the company received permission from the government of Alberta to produce oil sands bitumen at a new location in Dawson using a technique known as fireflooding, the third Petrobank operation that will use it; the 50% interest in Dawson was acquired in October from Shell Canada.〔(【引用サイトリンク】title=Petrobank gets approvals for Dawson oilsands project )〕 Revenue was about three times higher (1.1 versus 0.415 billion) and conventional oil production rate twice as much (83.9 versus 42.5 thousand bbl/d) in the first half of 2010 compared to the first half of 2009 (the large increase in total revenue during that period can be credited equally to PetroBakken and Petrominerales, each rising 160-170%). Compared to the last quarter of 2009 the second in 2010 had 40% more revenue, 60% more operating income and a 24.1% rise in asset value compared to only 4.6% for long term debt.〔(【引用サイトリンク】title=Petrobank )〕 PetroBakken operations produced 3.5% more barrels of oil equivalent than Petrominerals in the first half of 2010 compared to 4.6% less a year earlier (by the third quarter PetroBakken 40,095 boe per day (most light oil) .〔(【引用サイトリンク】title=Petrobank Second Quarter 2010 Results )〕 Though not yet a significant producer when compared to PetroBakken and Petrominerales, the HBU heavy oil division has the largest contingent resource base in terms of both net present value and total resources. Every year since 2006 the share of Petrobank's total resources attributable to Petrominerales has grown progressively smaller (mostly because of PetroBakken's more rapid growth (145% growth in net present value in 2009 compared to 69% for Petrominerales).〔(【引用サイトリンク】title=Petrobank Energy and Resources 2010 Third Quarter Report )〕 Its Whitesands operations (subsidiary Whitesands Insitu Inc, HBU heavy oil) may contain 1.8-2.6 billion barrels of oil.〔(【引用サイトリンク】title=petrobank plans 225 million oil sands project )〕〔(【引用サイトリンク】title=Petrobank announcement )〕 Only PetroBakken produces natural gas. ==Acquisitions/Divestments== *In May 2009 the parent company reduced its ownership in petrominerales from 76.9% to 66.8%. *In August 2009 Petrobank purchased tristar oil and gas ltd in a 2.24 billion dollar deal. It then formed PetroBakken by combining its Canadian operations with the tri star oil and gas division. *In the third quarter of 2010 the company purchased the 50% interest Baytex Energy Ltd.’s and Shell Canada had in Kerrobert and Dawson's heavy oil projects and advanced operations at Kerrobert (phase 1 expansion was started, phase 1 production grew to 380 bpd in November, phase 2 construction began). Petrobank's advanced and patented (holds multiple THAI technology related patents abroad) heavy oil extraction technology gives it a strong interest in enlarging its heavy oil asset base.〔 *On October 19, 2010 it was reported that Petrobank Energy purchased half of the Dawson heavy oil project from Shell Canada. The transaction (which included a couple other assets) cost C$15 million in net cash.〔(【引用サイトリンク】title=Petrobank acquires oil assets from Baytex, Shell )〕 *As of December 31, 2010 Petrobank's spinoff of its 65% Petrominerales stake will be completed. The new independent company will be called New Petrominerales. Rather than being compensated with cash Petrobank shareholders will each receive 0.614 shares of New Petrominerales for each Petrobank share they own while each shareholder of Petrominerales (before the reorganization) will receive 1 share of the new company.〔(【引用サイトリンク】title=Petrobank and Petrominerales Confirm Timing of Reorganization )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Petrobank Energy and Resources」の詳細全文を読む スポンサード リンク
