Control sand production and maintain well performance with a rigless solution
Talk to an ExpertSand production can limit how a well performs. As solids enter the wellbore, operators often reduce drawdown, increase cleanouts, or shut in production to avoid equipment damage. In many cases, the well still has value but cannot be produced at its full potential.
The SandTrap® XL formation consolidation service addresses this challenge by stabilizing sand at the source. Strengthening the near-wellbore region helps sustain production while keeping the impact on flow minimal.
Formation consolidation can be applied early to prevent production loss or later to restore output in wells already affected by solids.
Unconsolidated formations begin to produce sand when they can no longer withstand drawdown. As formation grains shift, solids enter the wellbore and lead to erosion, equipment wear, and repeated intervention, and costly sand treatment at surface.
A low-viscosity, externally activated resin bonds formation grains in place. Consolidation strength increases, while permeability reduction remains minimal.
Once placement is complete, a short shut-in period allows the treatment to set before the well returns to production.
Placement consistency often determines whether a treatment performs as planned. With internally catalyzed solutions, curing begins during pumping, which can limit how far the treatment can travel.
Separating placement from activation gives operators more control during execution. The resin remains pumpable during placement, helping improve coverage across the intended interval before consolidation begins.
Greater flexibility during pumping supports longer intervals and more consistent results in wells with changing conditions.
Well conditions can limit the effectiveness of traditional sand control methods. High temperatures and exposure to reactive fluids are common challenges.
The consolidation chemistry performs in temperatures up to 550°F (288°C) and resists acid, hydrogen sulfide, and carbon dioxide. Thermal operations such as steam injection also benefit from improved formation stability.
These capabilities support application in wells where high temperatures or reactive fluids can limit other sand control methods.
Access and cost often determine whether sand control is feasible. Mechanical solutions frequently require a rig, adding cost, time, and operational complexity.
A rigless placement option allows treatment through existing completions using bullheading or coiled tubing. No additional downhole hardware is required, which makes it practical in wells where screens or gravel packs are not an option.
Mechanical sand control systems, such as screens or gravel packs, block sand from entering the wellbore. While effective, those approaches can limit access to the formation by creating a mechanical restriction in the well, making follow-up treatments more difficult.
The base pipe in mechanical systems can also limit direct access to the sand face, which may reduce the effectiveness of future treatments.
Formation consolidation strengthens the formation instead of blocking it. Solids are controlled while the wellbore remains accessible for future work.
Both primary and remedial applications are supported, including wells where mechanical methods have not performed as expected.
Formation composition plays a key role in consolidation performance. Higher clay content can reduce the effectiveness of many treatments.
Design parameters support formations above 50 mD, with applicability in reservoirs containing up to 20% clay, which is typically higher than many conventional approaches. This broadens the range of wells where consolidation can deliver consistent results.
