Pre-P&A with Interwell`s Intelligent Barrier Valve
Having been drilled and completed in April 1997, with 5,5” 23 lbf/ft production tubing, the well was ready for P&A after producing hydrocarbons for almost 22 years. To improve cost efficiency, the aim was to do the job off-line. The requirement was to set a deep plug, cut deep, and circulate heavy brine before completing a shallow cut. In line with the NORSOK standard, a shallow plug had to be set to prevent hydrocarbons from migrating to the surface.
The client wanted the ability to kill the well with a heavier fluid if a pressure increase was observed. To reduce cost this needed to be done remotely, off-line if possible.
Intervention free Subsea Completion
Many subsea installations are planned to operate with a vertical x-mas tree (VXT). Installing VXT’s from a semi-submersible is costly and time consuming. Efficiency can be improved in large subsea fields, both in the drilling and completion phase, by performing these operations in batches. By temporarily abandoning the well after the completion is installed and the BOP has been pulled, the rig rate cost is kept at a minimum. Installation of the VXT’s is then carried out by a Light Well Intervention (LWI) vessel or an Inspection Maintenance and Repair (IMR) vessel.
