NFPS Compression Project FEED
1 INTRODUCTION
The reservoir pressure in Qatar’s North Field has been declining due to continuous production since
the early 1990s. The North Field is the world’s largest natural gas field and accounts for nearly all of the
state of Qatar’s gas production. The principal objective of the NFPS project is to sustain plateau from
existing QG South Operation – RL Dry Gas, RGE Wet gas and existing QG North Operation – QG1 &
QG2, production areas by implementing an integrated and optimum investment program consisting of
subsurface development, pressure drop reduction steps and compression. Refer to Figure below for a
schematic of North Field.

NFPS Compression Project FEED
Drilling and Looping Investments #1 and #2 are in execution phase and are being executed by I1P1
EPC, EPCO and EPCL projects with the exception of WHP13N, which will be part of NFPS
Compression project execution. The NFPS Compression Project involves the installation of large
offshore compression facilities at multiple locations. The compression facilities will be installed after the
completion of the Drilling and Looping Projects.
Qatargas Operating Company Limited is leading the development of the North Field Production
Sustainability (NFPS) Project. The principal objective of the NFPS project is to economically sustain
plateau from existing QG South (RGE, RL) and QG North (QG1 & QG2) production assets by
implementing an integrated and optimum investment program consisting of subsurface developments,
pressure drop reduction steps and offshore compression facilities installation.
CONTRACTOR is awarded to perform FEED for NFPS Compression Project – RGE, RL and QG2
Facilities.
