East West Gas Pipeline abbreviated as EWPL is a project implemented to transport gas from Kakinada (Andhra Pradesh) to Bharuch (Gujarat) including various spurs and interconnects on the way. EWPL traverses through the Indian states of Andhra Pradesh, Karnataka, Maharashtra and Gujarat. EWPL has been authorized as a common carrier pipeline.
The East West Gas Pipeline supplies Natural gas to RIL's vast petrochemical complex at Gujarat and delivers gas to numerous customers via branch line connections along its length. The pipeline system features multiple compressor stations, numerous metering facilities at branch take-offs and an advanced control and communications network. The project is the first and largest privately owned cross-country pipeline in India and the backbone of India's burgeoning natural gas grid.

Gas source
The current gas source for EWPL is KG-D6 gas block located in Krishna Godavari Basin, 30 to 50 km offshore of the east coast of India. RIL has set up an Onshore Terminal at Gadimoga near Kakinada.
System configuration
EWPL is a 48 inch uniform diameter (API 5L Grade X-70) pipeline across the entire trunk length of around 1375 km with wall thicknesses 17.2, 20.7 and 25.4 mm depending on the code requirement. The pipeline is 3LPE (three layer polyethylene) coated; internally epoxy lined, helically spiral submerged arc welded (for 17.2 mm) and longitudinal submerged arc welded (for 20.7 mm and 25.4 mm). Impressed current cathodic protection system has been provided to supplement the coating system for protection against external corrosion. Maximum Allowable Operating Pressure (MAOP) of the pipeline is 98.0 bar(g).
Gas price
Recently, Indian government fixed the natural gas price at producer end (on shore point) as 5.61 US$ per mmbtu on net calorific value (NCV) basis compared to earlier price of 4.2 US$ per mmbtu on gross calorific value basis. However the enhanced price would be applicable only after compensating the shortfall gas in the previous years. The earlier price of 4.2 US$ per mmbtu on gross calorific value (GCV) basis is calculated already at maximum price cap of Brent crude (US$ 60/bbl) under the applicable formula linking the price of gas per mmbtu (GP) to the price of oil:
GP = 2.5 + (OP – 25) ^0.15
where OP is the annual average Brent crude price for the previous FY, with a cap of USD 60/bbl and a floor of USD 25/bbl. As the annual Brent price has always been above US$ 60 since 2007, the revised gas price at 5.61 US$ during the year 2014 is in excess of the applicable price by nearly 20%.
