SwellPolymer LCM
RXSOL SwellPolymer LCM is a cross-linked, water-swellable polyacrylamide-based polymer designed for use as a Loss Circulation Material (LCM) in horizontal drilling, HDD and drilling-fluid applications.
The dry polymer rapidly absorbs water and expands to many times its original volume, producing a soft, cohesive and highly swollen polymer mass. When placed into permeable zones, fractures, voids or unconsolidated formations, the swollen material helps bridge, seal and reduce fluid losses.
Unlike conventional water-soluble polyacrylamides, RXSOL SwellPolymer LCM is cross-linked and insoluble in water. It retains its polymeric structure while absorbing and holding large quantities of water.

Precautions & Remarks
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.
Procedure
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.

Keywords
How to control lost circulation?
Depending on the particle size and concentration used, RXSOL SwellPolymer LCM can work through several mechanisms:
Particle Bridging
Polymer particles enter openings and bridge across fractures and permeable pathways.
Swelling
Following water contact, particles expand and occupy additional pore/fracture volume.
Plug Formation
Swollen particles consolidate into a flexible plug that restricts further drilling-fluid movement.
Formation Stabilization
The swollen polymer can help bind loose or unconsolidated material and reduce fluid invasion.
