INTRODUCTION

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 reservoir pressure in the North Field has been declining due to continuous production since the early 1990s. The principal objective of the NFPS Project is to sustain the 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 the figure below for a schematic of the North Field.
