The technique of Sequential Re-completions does not require pre-installed isolation tools on the liner nor does it require plugs in the liner after the re-completion is depleted.
It is designed to perforate, stimulate, and put the well on pump in one run.
Inflow from the perforated interval is contained such that sand & oil inflow is delivered directly into the pump intake.
The pump is landed at the perforations to provide maximum drawdown maximizing sand inflow and oil recovery.
Well servicing and flush-by operations can be carried out by equipment readily available locally.
Besides re-completing currently non-productive horizontal wells, there are about a half dozen more opportunities for using sequenced re-completions to restore productivity and value to cold heavy oil assets.
