DrillWall™ – Lost Circulation Material (LCM)

DrillWall, Lost Circulation Material, LCM, kenaf, hemp, oil drillingIndustrial Hemp Manufacturing LLC (IHM) is a wholly owned subsidiary of Hemp, Inc. that produces lost circulation material (LCM) and spill absorbents for the oil and gas industries.

About Lost Circulation Material (LCM)

In oil or gas well drilling, lost circulation occurs when drilling fluid, known commonly as “mud”, flows into one or more geological formations instead of returning up the annulus. Lost circulation can be a serious problem during the drilling of an oil well or gas well.

All types of materials are used to stop fluid loss in the drill-hole as it leaks out into cracks, fissures, sand, salt and other porous formations. Lost Circulation Material (LCM) is a term for substances added to drilling fluids when drilling fluids are being lost to the formations downhole.

Some of the commonly used lost-circulation materials include fibrous (tree bark, shredded cane stalks, mineral fibers and animal hair), flaky (mica flakes and pieces of plastic or cellophane sheeting) or granular (ground and sized limestone, carbonates or marble, wood, nut hulls, formica, corncobs and cotton hulls).

The cost of lost circulation materials varies from $.20 cents a pound for sawdust to over $10 dollars a pound for synthetic loss circulation materials with special polymer compounds. Most drilling fluid engineers have a LCM formula that uses a mixture of several materials even for drilling through rock formations that are low loss (very few holes, cracks or porous areas).

lost circulation materialDrillWall™ is insoluble in water, non-toxic, biodegradable drilling fluid additive used in oilfield drilling applications. It acts as a borehole stabilizer, a lubricating agent, as well as preventing differential sticking.

The DrillWall™ product is a mixture of micronized organic cellulose fibers and provides excellent seepage and loss circulation control.

DrillWall™ has been field-proven for all types of drilling fluid formulas including water-based fluids (WBM), oil based fluids (OBM), synthetic based fluids (SBM) and constant rheology fluids (CR-SBM). It has been used in all types of high loss geology formations including sand, fractured shale, pre-salt, pea gravel and other highly porous formations. It can be mixed through the mud hopper or directly into the mud tank at the agitation point.

The DrillWall™ Lost Circulation Material (LCM) product works faster to plug the leaks and is cost competitive with most LCM materials. It is non-toxic to the workers and it works with any type of drilling fluid. On a cost-performance basis it is superior to most LCM’s in the market place.

The DrillWall™ LCM product has been tested and used by many of the world’s largest oil and gas companies including: Chevron, Aramco, Petrobras, Ultra Petroleum and others.

DrillWall™ is priced from $1.75 to $3.00 per pound (depending on whether polymer additives are used in our formulation). This places DrillWall™ in the middle price range. However it works faster and better than many of the LCM products that cost $9 to $12 per pound.

DrillWall™ LCM ships in standard 40 foot shipping containers. It is not restricted and is not considered a hazardous material that requires specialized handling. The product is packaged in 25 pound multi-ply, paper bags on flame treated wood pallets and is wrapped for moisture protection.
