Product Short Description: Water soluble polymer for use as Loss Circulation Material in drilling work
Product Description:

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.

Product Application:

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

RXSOL SwellPolymer LCM may be introduced directly into the drilling fluid or used as a pre-hydrated treatment.
 
Method A - Dry Addition
  • 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.
 
Method B - Pre-Hydration
 
Pre-hydration can be used where rapid swelling and plugging are required.
  1. Fill a clean mixing tank with compatible water.
  2. Start moderate agitation.
  3. Slowly add RXSOL SwellPolymer LCM.
  4. Allow the polymer to hydrate and swell.
  5. Continue mixing until a uniform swollen polymer slurry/gel is obtained.
  6. Pump or place the swollen material into the designated loss zone.
  7. Allow sufficient static contact time for formation of the sealing plug.
 
Do not add large quantities of dry polymer at once, as rapid hydration can cause lump formation and uneven dispersion.

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.
