QPT has extensive experience and techniques to assess and develop engineering solutions for Well Rejuvenation
1) Scope of Work
a. Revisit well-by-well plan for existing producing wells.
b. Analyze idle wells history and performance, and propose reactivation plan.
c. Analyze gas lift utilization and propose for improvements.
d. Scrutinize on the surface facilities limiting factors and initiatives identified to overcome it.
e. Assessment on the metering and well test issues.
f. Explore new technology application suitable for selected field
2) Deliverables
a. Systematic short-term and medium-term strategy
b. Stepwise approach implementation plan:
– Rankings and prioritizations
– External input
c. Clear guideline to address gas lift constraint and gas lift distribution.
d. Findings on operational problems and recommendations to resolve the problems.
e. Idle well reactivation plans.
f. Expected production gains, deferment reduction or operational benefits from each of the recommendations.
g. Clear pre and post implementation data acquisition plan.
h. Estimates of implementation cost, monitoring plan and team members for all the recommendations.
