Wells drilled and completed following the approved field developed plan (FDP) may not yield satisfactory performance results as predicted at the FDP phase. The gap could be due to accumulation of various uncertainties and risks encountered in each phase of field development planning from reservoir characterization, flow dynamic properties, well reservoir penetration and production optimization, well design, drilling and completion, to well support surface facilities design and implementation.

This paper delineated the issues/challenges in each key task of field development planning focusing on three key areas for improving quality assurance in (1) reservoir simulation, (2) drilling and completion, and (3) production system. Real field example cases were used to illustrate the need to improve integration of pre-during-post FDP strategies and approaches. The paper also provides simple and short check lists on requirements and workflow for helping to assure FDP well production throughout the field life.
