PUMPABLE SEAT ASSEMBLY AND USE FOR WELL COMPLETION

摘要

An assembly and process for fracturing, stimulating and producing a wellbore having a plurality of oil or gas producing zones is provided comprising introducing into the well the pumpable seat assembly comprising a generally cylindrical tube having an outer diameter and an inner diameter with an upper end forming a ball seat; setting the pumpable seat assembly below an oil or gas producing zone to be produced; introducing a dissolvable ball into the well, said dissolvable ball having a sufficiently large enough outer circumference so that it can sit on the ball seat and temporarily restrict a flow of fluids to the portion of the wellbore located below the pumpable seat assembly; and fracturing the oil and gas producing zone to stimulate oil or gas production; whereby the biodegradable ball is configured to dissolve within a predetermined period of time so that when it dissolves any oil or gas produced from zones below the pumpable seat assembly can flow through the cylindrical tube.
