INTRODUCTION
The North Field is the world’s largest natural gas field and accounts for nearly all the State of Qatar’s gas production. The principal objective of the NFPS projects is to sustain plateau from existing QatarEnergy LNG Operation – S1, S2, S3, N1 and N2, production areas by implementing an integrated and optimum investment program consisting of subsurface development, pressure drop reduction steps and compression.
NFPS projects comprise 3 main investment programs:
- Investment #1: Drilling and Associated Facilities [WHP12S/ WHP13S/ WHP14S/
WHP12N/ WHP13N]
- Investment #2: Trunk line Looping and Intra-field pipeline looping [32” PL1LN, 32”
PL1LS, 38”PL610LS]
- Investment #3: Compression Complexes and associated facilities [Phase 1 CP6S & CP7S; Phase 2: CP8S & CP4N; Phase 3: CP4S & CP6N Phase 4: CP1S & CP1N]
Drilling and Looping, Investments #1 and #2, projects are in execution phase and are being executed as I1P1, EPCOL Projects except for WHP13N, which will be part of NFPS Compression Projects execution which compromises total up to 9 COMPs.
