Scope of Work - Letang Tengah Rawa Optimization (LTRO) Project

· The Letang, Tengah, and Rawa fields are three of eight gas fields located in the Corridor Block in South of Sumatra, Indonesia. Letang, Tengah & Rawa Fields are dedicated for the Chevron GSA.

Rawa  station  is  currently  in  operation,  producing  oil,  and  the  compression system is currently used for gas reinjection.

It is  envisaged  that the  Rawa  compression  facilities  has  sufficient discharge head to deliver dehydrated gas to Grissik CGP.

The  gas  outlet  from  the  dehydration  system  will  thus  be  diverted as  sales gas instead of for gas reinjection.

The  total  produced  gas is  then  delivered  to  Grissik  via  newly built  12”  gas pipeline.

· The LTRO  development scenario is to reactivate Letang Tengah wells and flowline (which had been shut-in since 2003, currently in mothballed condition).

Reactivation of Letang and Tengah fields will  also  generate of  condensate which will require additional liquid handling facilities to supplement the existing facilities installed at Rawa Station  likes:  install  condensate  stabilization  unit & storage tank and  upgrade  safety / shutdown / utilities  system at  Rawa  Station, tie-ins modification in Grissik CGP and Letang Tengah Station.
