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]
