Remedial Sand Control

Restore production and completion integrity in unconsolidated formations

Eliminate plugging and repair damaged screens and casing

Sand management efforts are most effective when engineered and deployed early in the life of the well, but early water breakthrough or high drawdown in a mature well can lead to unexpected sand and fines that hinder production and damage lifting equipment. In addition, even the most robust, well-engineered sand control technologies require remediation after many years of corrosion, erosion, or plugging damage.

Choose technologies to suit your well economics 

From conventional straddle packers that shut off a damaged screen to state-of-the-art chemical systems that stabilize sands with little permeability impairment, we have a full range of technologies to help you restore production and completion integrity and prevent further damage. 

WellWatcher Flux multizonal reservoir monitoring system
Sand Screen Cleanout
Fluids are pumped to wash or dissolve sand, fines, and scale from a plugged sand screen or gravel pack. These operations may use a high-energy jetting tool on coiled tubing to ensure deep penetration.
Chemical Sand Treatment
Artificial tackifying chemicals (agglomerants) or binders (conglomerants) are injected to stabilize formation material while maintaining sufficient permeability to enable production.
Through-Tubing Gravel Pack
A filter is created across the perforated intervals to retain formation sand and prevent jetting damage to the completion (including new through-tubing screens or casing patch).
Through-Tubing Screen or Patch
A new sand screen or casing patch is deployed into the well through the existing tubing or damaged screens and hung across or above the perforated interval.
