Reservoir Optimized Conformable Sand Control Completion in OilReservoirs

摘要

In recent years,shape memory polymer materials(SMP)and conformable sand control technology haveshown significant advantages to conventional gravel packing or expandable screen solutions by providingthe right combination of operational simplicity,total conformance,wellbore stability,and superior filtrationrequired for long-term sand control and effective production inflow from reservoirs.Contrary to gravelpacking that requires most of the wellbore length to be covered by screen to help dehydrate the slurry,the shape memory material may be placed selectively across the sweet spots.This has led to the questionabout how much of the intervals would need to be covered to get maximum productivity with the minimumSMP coverage,thereby impacting the overall completion cost.This paper utilizes reservoir modeling basedwell completion simulation to evaluate the impact of the SMP cartridge design configuration and reservoirproperties on well production performance and provide optimized screen design solutions to maximize wellproduction in oil reservoirs.The reservoir model and horizontal well completion with the SMP cartridge modules are built in areservoir simulator.Three categories of simulation cases are performed to investigate their impact onproduction:the number of cartridges per well segment,cartridge locations and spacing,and reservoirproperties such as permeability and capacity.These case results are compared with a base case where conventional standalone screen is used.Thecomparisons are used to define maximized and/or most economical sand control solutions.The resultsprovide an effective optimization solution for maximized cumulative well production in oil reservoirs.In low rate wells,the simulation results also provide a more economical solution for cost sensitive wellcompletions.Simulation results demonstrate significant production improvements with conformable SMPtechnology over conventional screens and provide a useful workflow to optimize completion designs fordifferent reservoirs.
