During the well production lifecycle, particularly in the Permian basin, a well can start producing high levels of water. This minimizes the amount of hydrocarbons that can be recovered without increasing the level of processing. Traditional methods often used for resolving this issue include abandoning the well and drilling a new one which is costly and time consuming.
On a project in Wyoming, USA, production logs highlighted a cluster on an 18 stage completion was producing water. Our ReLine MNS cased hole patch system was chosen as an effective solution to shut-off the section.
The internal patch provides reliable mechanical wellbore isolation to allow efficient production of the well to continue, with no restrictions created within the wellbore.
The expandable patch was deployed across the cluster producing water at 12,085ft as well as the neighbouring cluster at 12,018ft to prevent water breakthrough in the future. Three seals joints were installed along the patch for complete zonal isolation.
The ReLine MNS successfully expanded over two clusters in one trip, with no requirement for a shoe drill out.
Benefit
- Eliminated the requirement for costly and time consuming abandonment
- Rig time savings achieved with no shoe drill out required
- Corrosion interval successfully isolated
- System pressure tested to more than 10,000psi
