Project Profile
Value: $1,450 Million
Start-up year: 2015
Upstream Gas Reserves: 622 billion ft³
The project involves a two well appraisal drilling programme for the CY-D5 discovery, located in deep water Cauvery Basin. During testing over two intervals the well flowed 550 bopd and 1MMscf/d (million square cubic feet per day) of gas in zone one, and in zone two flowed, 31 MMscf/d of gas and 1,200 barrels of condensate per day. Base case estimates peg gas reserves in the area at 622 Bcf and condensate reserves at 11 mmboe.
The development concept being considered involves a subsea tieback to an onshore terminal through a 48km pipeline. The flowlines from wells will be connected to a manifold to be installed at a water depth of 1,000m. The installation of a subsea compressor station has been envisaged near the manifold, at a later stage, when the tubing head pressure declines and becomes insufficient to transport the produced hydrocarbons to the onshore terminal. A separate power umbilical will be required to meet the power requirements of subsea compressor and pumps.
