Engineering Solutions for Today's

Heavy-Duty Challenges

Our proven line of cutting-edge HDD additives was developed to solve some of the industry’s most challenging problems: inadvertent returns, unstable formations, and extreme drag. Through the use of our proprietary lubricants, sealants, and inhibitors, we assist our customers in completing their crossings on time and under budget.

Built for the Toughest Crossings

Our advanced line of HDD additives is designed to handle the conditions that slow projects down and drive up costs, including inadvertent returns, unstable formations, excessive torque, and high-drag environments. Proven in the field, these solutions combine high-performance lubricants, sealants, and clay inhibitors to strengthen the borehole, improve fluid efficiency, and maintain consistent drilling conditions. The result is a more controlled operation that helps crews reduce risk, protect the wellbore’s integrity, and complete crossings on schedule and within budget.

Viscosifiers

Core Chemistry

RheoXanD

Core Chemistry

A dry powder viscosifier that provides superior viscosity, enhancing cuttings suspension and hole cleaning. Compatible with bentonite and other drilling chemicals, it can be used standalone or alongside other additives and mixes easily with good agitation.

Core Chemistry

ThinGuard

Fluid Thinner

A highly active aqueous thinner and deflocculant that rapidly reduces viscosity and gel strengths at low concentrations. Also assists in fluid loss control and can be circulated as a concentrated slug to remove wall cake and mud buildup from the bore, rods, and tooling.

Core Chemistry

HydropH⁺

pH Control

A general water conditioner that raises pH and treats out hardness in make-up water, allowing for optimal bentonite hydration and greater yield. Should be added to make-up water prior to bentonite, it mixes easily with good agitation and is compatible with other drilling chemicals.

Sand, Clay, and Shale Solutions

Heavy-Duty Series

HydroForce

Clay Hydration Inhibitor

A proprietary blend of liquid clay stabilizers designed to stabilize water-sensitive formations and prevent hydration, it inhibits clays by suppressing the swelling and hydration associated with water absorption. Prevents bit balling at ultra-low concentrations while maintaining superior cuttings integrity.

Heavy-Duty Series

HydroDET

High-Performance Detergent

A water-soluble blend of surfactants that prevents clays and shales from sticking to rods and tooling, delivering strong detergency and effective performance at low concentrations. Compatible as a standalone product or alongside other additives.

Heavy-Duty Series

RheoBore

Clay & Shale Inhibitor

A soil stabilizer, viscosifier, and friction reducer that delivers excellent cutting encapsulation of clays and shales, while enhancing hole cleaning and providing lubricity to the bore.

Heavy-Duty Series

RheoPac

Fluid Loss Controller

A dry powder fluid loss control additive that reduces fluid loss to the formation while forming a thin, slick filter cake for consistent borehole stability. Free of fillers or cutting agents, RheoPac delivers the highest quality PAC available, with the regular version also providing additional viscosity to the drilling fluid.

Heavy-Duty Series

DrillSeal HDD

Loss Prevention

A blend of natural fibers whose deformable, compressible particles conform to pores and fractures to create a lasting seal against fluid loss and inadvertent returns.

Specialty Products For Challenging Bores

Heavy-Duty Series

LiftGuardDRY

Cuttings Transport Optimizer

A dry blend of oxides and pH buffers that enhances shear-thinning properties in bentonite-based fluids, providing exceptional cuttings suspension and transport in heavy sand, gravel, and cobble conditions.

Heavy-Duty Series

HydroSlide

Premium Lubricant

An environmentally friendly, hydrocarbon-free lubricant that coats rods and tooling to provide superior lubricity, reducing torque and drag during drilling and pullback while preventing clay adhesion. Compatible with bentonite and other drilling chemicals.

Heavy-Duty Series

HDD Defense

Inadvertent Return Sealant

A blend of environmentally safe sealants and swellable materials designed to remediate frac outs and inadvertent return events, compatible with any drilling fluid.
