METHOD FOR MANAGING THE PRODUCTION OF A WELL

摘要

The current invention provides a method for isolating selected downhole zones of a wellbore. The method utilizes pre-perforated conduit wherein the perforations have been temporarily sealed prior to positioning downhole. A resin-coated particulate, which forms a permeable solid mass to filter and prevent the introduction of formation sand or fines during well production and is used to secure the pre-perforated casing in the wellbore. The pre-perforated casing, permeable solid and formation are perforated and the resulting perforations filled with a curable composition which cures as an impermeable solid. The impermeable areas define individual downhole zones. Devices such as straddle packers or expandable tubes encapsulated in impermeable sleeves are used to isolate the resulting zones.
