There are three major gas pipeline networks in India operated by GAIL, RGTIL, and GSPL, totaling over 15,800 km. GAIL operates the largest network at around 10,000 km, transporting gas from offshore fields and imported LNG. RGTIL's 1,469 km East West Pipeline connects fields in Andhra Pradesh to markets in Maharashtra and Gujarat. GSPL's network of around 2,200 km is focused in Gujarat. The gas transported comes from various offshore fields in the KG-D6 basin, Mumbai, Cambay, and others, as well as imported LNG.

1. Gas Pipeline Networks in India
1. Existing Pipeline Network
There are presently three major pipeline entities in gas transportation across the
country namely GAIL, RGTIL and GSPCL. GAIL is operating HVJ & DVPL
trunk pipeline to evacuate gas like APM , JV gas from ONGC and R-LNG from
PLL, consisting about 10977 km (about69.44%) including Dabhol-Banglore-
Pipeline. RGTIL is operating 1469 km (about 9.29%) East West pipeline (EWPL)
to evacuate gas from KG-D6 gas in Andhra Pradesh. This pipeline passes through
Andhra Pradesh, Maharashtra and Gujarat and integrated with GAIL’s and GSPL’s
network to reach Northern and Western Indian market. GSPL is mainly focused in
the state of Gujarat consisting about 2198 km (about 13.90%). In addition GAIL
also operates regional gas pipeline networks across India in Maharastra,
K.G.Basin, and South Gujarat.
The spread of pipeline network of different transporter is given as under:
Transporter (Length in KM) (% share)
1 GAIL 10977 69.44%
2 RGTIL 1469 9.29%
3 GSPL 2198 13.90%
4 AGCL/OIL* 1000 6.33%
5. IOCL 142 0.90%
6. ONGC 24 0.15%
Total 15808 100%
* Approximately
The natural gas is primarily sourced from KG-D6, Mumbai offshore, Cambay
Basin, Ravva Offshore, KG Basin, Cauvery basin and Imported LNG.
