Colorado Interstate Gas (CIG) is a major producer of natural gas, connected to major supply basins in the Rocky Mountains and production areas in the Texas Panhandle, western Oklahoma, western Kansas, and Wyoming. Originally an independent company, CIG is now a subsidiary of El Paso Corp. ==History== In 1927, three companies with the natural gas leases, the market and the money combined with the know-how, came together to form the Canadian River Gas Company, which produced the gas from the Panhandle Gas Field and piped it to Clayton, New Mexico, where Colorado Interstate Gas Company purchased it and transported it to Denver.〔CIG The Gasser, January 1978, p. 8〕 CIG began service on 1 June 1928 and gas first reached Pueblo, Colorado, on 19 June, and Denver on 22 June on a route established by John Paul (Mr. Mac) McClintock.〔CIG The Gasser, January 1978, p. 8〕 In 1928, CIG has 428 miles of pipeline and 105 employees.〔CIG The Gasser, February 1978, p. 9〕 The original pipeline was 20-22 inches in diameter, five hundred miles long, trenched by ditching machines but some portions dug by hand, linked by Dresser coupling rather than welded, and limited to 50 psi.〔CIG The Gasser, January 1978, p. 8〕 The Bivins Compressor Station, using three Worthington Corporation compressors of 1000 HP each, was the first soon followed by Clayton and Devine and the introduction of electric welding.〔CIG The Gasser, January 1978, p. 9〕 In 1938, CIG has 633 miles of pipeline and 145 employees.〔CIG The Gasser, February 1978, p. 9〕 Corporate headquarters were in Colorado Springs and the company introduced a group life insurance program and a death benefit plan in the early 1930s, followed by a retirement income plan in 1939, a medical plan in 1940,〔CIG The Gasser, January 1978, pp. 9-10〕 and a credit union〔CIG The Gasser, April 1978, p. 10〕 The Cimarron Station came on line in 1941, followed by the Apishipa Station in 1943.〔CIG The Gasser, January 1978, p. 10〕 The McClintock Station was operational in 1944 followed by the East Denver and Lakin Stations in 1947, the latter connecting Denver to the Hugoton Gas Field.〔CIG The Gasser, January 1978, p. 10〕 The company was using shortwave radio communication and airplane pipeline patrols by 1948.〔CIG The Gasser, January 1978, p. 10〕 The Kit Carson Station was online by the end of the decade.〔CIG The Gasser, January 1978, p. 10〕 In 1951, The Canadian River Gas Company merged with CIG, and the Fourway Station came online in 1952.〔CIG The Gasser, January 1978, p. 10〕 The Springfield, Keyes, Sanford and Morton Compressor Stations came online in 1953.〔CIG The Gasser, January 1978, p. 11〕 In 1957, the Mocane and Laverne stations came online.〔CIG The Gasser, January 1978, p. 12〕 In 1958, CIG has 3470 miles of pipeline and 951 employees.〔CIG The Gasser, May 1978, p. 5〕 In 1960, the company opened the Rawlins Compressor Station and introduced an employee Thrift Plan.〔CIG The Gasser, January 1978, p. 12〕 CIG changes its name to CIC to reflect its four major businesses, Pipeline, Chemical (Wycon), Petroleum and Manufacturing (Marsh acquired in 1956, Metal Forge and DeZunk acquired in the early 70's).〔CIG The Gasser, June 1978, p. 2〕 In 1972, CIG merged with Coastal States Gas Corporation.〔CIG The Gasser, January 1978, p. 12〕 CIG's deepest wildcat, Johnson #1, drilled in the Texas Panhandle at 14,000 feet.〔CIG The Gasser, June 1978, p. 5〕 In 1976, CIC changes its name back to CIG (Manufacturing division was sold to General Signal Corp. in 1972).〔CIG The Gasser, June 1978, p. 2〕 In 1978, CIG has 5185 miles of pipeline and 1142 employees.〔CIG The Gasser, February 1978, p. 9〕 Coastal merged with El Paso Corp. in 1999, which was bought by Kinder Morgan in 2011. 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「Colorado Interstate Gas」の詳細全文を読む スポンサード リンク
