STRADDLE RECOVERY

Objective
The well is a gas producer with a deviation of 48° that was completed with 5" completion in 1985. It had ceased production due to a sand plug on top of the straddle in the well. The primary objective was to retrieve the straddle without killing the well on the formation, set a plug in the tail pipe and replace the leaking Cr-13 completion.Location
The well side is located in an environmentally-sensitive part of a protected dune area. The use of the HWO unit will have a major impact on how operations affect the local environment:- Significant reduction in trucking operations to rig up and rig down the HWO unit compared to a normal drilling unit
- Reduced visibility of the HWO unit (no derrick structure)
- Lower noise level than a normal drilling unit
Planned Execution
- Successfully retrieved the straddle
- Completion recovery and packer milling successfully carried out
- Compliments from nearby residents on minimal disturbance
- Well is producing as expected
