Downhole Electronic Valve & Mud Pulse Telemetry Integration for Multizone Open Hole Gravel Pack Deployment Optimization

Abstract The deployment of multizone Open Hole Gravel Packs (MZ-OHGP) with hydraulically set isolation packers generally would require two runs. This system has been streamlined to a single trip operation via integration of a Downhole Electronic Valve with mud pulse (DEV-MP) telemetry. Field F is a field comprising of three wells, with each well containing four distinct zones of interest with the need of sand control, gave rise to a trial of a single trip MZ-OHGP system through modification of existing shunted screen technology in combination with the DEV-MP. In a two runs MZ-OHGP system, the first trip is performed to convey the screen bottom hole assembly (BHA) to depth followed by setting the gravel pack (GP) and isolation packers. The second trip is then run to convey the service string consisting of the GP tool and diverter valves to initiate shunt packing. With the combination of the DEV-MP and modifications to the service string the packer setting and GP operations can now be optimized into a single trip via conversion of the packer setting tools to GP tools upon actuation of the DEV-MP.
