The original project started on 15 March 1995 when an inaugural memorandum of understanding between the governments of Turkmenistan and Pakistan for a pipeline project was signed. This project was promoted by Argentinian company Bridas Corporation. The U.S. company Unocal, in conjunction with the Saudi oil company Delta, promoted an alternative project without Bridas' involvement. On 21 October 1995, these two companies signed a separate agreement with Turkmenistan's president Saparmurat Niyazov. In August 1996, the Central Asia Gas Pipeline, Ltd. (CentGas) consortium for construction of a pipeline, led by Unocal, was formed. On 27 October 1997, CentGas was incorporated in formal signing ceremonies in Ashgabat, Turkmenistan, by several international oil companies along with the Government of Turkmenistan.
