India invited to participate in Turkmenistan-Afghanistan-Pakistan pipeline By Oil and Gas Journal editors HOUSTON, Apr. 16 -- Oil and gas ministers from Pakistan, Turkmenistan, and Afghanistan formally invited India on Apr. 9 to participate in their proposed Turkmenistan-Afghanistan-Pakistan natural gas pipeline project (OGJ Online, Feb. 27, 2003) reported OPEC News Agency. Participants said New Delhi's participation in the $2.5-3.2 billion project would make it more viable, providing significant additional gas markets. The pipeline, estimated in various reports as 1,300-1,600 km long, would carry 20-30 billion cu m/year of natural gas and likely would be constructed to Pakistan's Sui field, from which existing infrastructure could be tapped to supply major local markets (OGJ, Oct. 7, 2002, p. 21).
