RXSOL SwellPolymer LCM is primarily designed for:
- Horizontal directional drilling (HDD)
- Horizontal drilling operations
- Drilling-fluid loss control
- Fracture sealing
- Highly permeable formations
- Unconsolidated formations
- Gravel and void zones
- Caving zones
- Lost-circulation zones
- Annular loss control
- Borehole stabilization
- Temporary plugging applications
How to use and control Lost Control Material
- Determine the severity and approximate size of the loss zone.
- Select an appropriate particle-size grade.
- Add the required quantity slowly into the circulating drilling fluid.
- Maintain sufficient agitation to achieve uniform dispersion.
- Circulate toward the loss zone.
- Allow sufficient residence/contact time for hydration and swelling.
- Monitor returns and fluid-loss reduction.
- Repeat treatment if required.
- Fill a clean mixing tank with compatible water.
- Start moderate agitation.
- Slowly add RXSOL SwellPolymer LCM.
- Allow the polymer to hydrate and swell.
- Continue mixing until a uniform swollen polymer slurry/gel is obtained.
- Pump or place the swollen material into the designated loss zone.
- Allow sufficient static contact time for formation of the sealing plug.

How does LCM Lost Circulation Material work in drilling?
When the dry polymer comes into contact with water, the cross-linked polymer network rapidly absorbs water.
The polymer particles expand and form a swollen, cohesive mass.
Dry polymer → Water absorption → Rapid swelling → Particle expansion → Fracture/void filling → Loss reduction
The cross-linked structure prevents the polymer from simply dissolving into the drilling fluid. Instead, the material maintains its three-dimensional polymer network while retaining absorbed water.
Key Features of using RXSOL LCM Swelling Polymer
- Rapid water absorption and swelling
- Can be pre-hydrated before application
- Swells several hundred times its dry volume under suitable conditions
- Helps seal fractures, voids and permeable formations
- Effective in unconsolidated and caving formations
- Useful for horizontal drilling and HDD operations
- Non-fermenting polymeric material
- Easy to handle, mix and apply
- Economical compared with many conventional LCM systems
- Remains as a cohesive swollen mass after hydration
- Particle size can be selected according to loss-zone characteristics
