DRILLING FLUIDS SELECTION GUIDE
CLAY CUTTER: Used on any size HDD bore to greatly reduce or eliminate clay
cuttings from sticking to each other and to the drilling tools. Swelling of the
bore will be reduced or eliminated; rotation and pullback pressures will be
significantly reduced.
CLAY CUTTER PRO: Dry, concentrated, non-hazardous, proprietary clay inhibitor
that can be used with either polymer or bentonite drilling fluid systems. An ideal
additive for HDD bores in reactive clay soils, and can be used in recycling systems.
DRILL-TERGE: Liquid solution of nonionic surfactant formulated to increase
detergency and wetting properties of drilling fluids. Designed to work in fresh
or saltwater to reduce torque and drag.
HERCUL-EZ: Proprietary additive used in conjunction with bentonite-based
drilling muds. With proper formulation, the system will produce a unique drilling
fluid with excellent shear thinning characteristics. At low shear or at rest, the fluid
will gel and allow for suspension of large cuttings, yet thins immediately under
pumping conditions. At rest, the fluid looks and behaves like a semi-solid but
when sheared, even slightly, reverts back to a thin, almost water-like consistency.
NSF/ANSI Standard 60 certified.
INSTA-VIS DRY: Highly concentrated, granular polymer ideal for sticky and swelling
clays, and shale. Increases rate of penetration and stabilizes the borehole, while
improving cohesion in sandy soil. Can be used in saltwater, such as tidal conditions.
INSTA-VIS LOW VISCOSITY: Easy-mixing, dry, water-soluble polymer used in
horizontal and vertical drilling applications. Compatible with recycling equipment.
INSTA-VIS PLUS: Liquid polymer designed to improve drilling efficiency in
both horizontal and vertical drilled holes through its rapid field mixing, viscosity
development, and clay and shale inhibition. Can be used with VERSAFOAM PLUS
to stiffen, and in brackish water. NSF/ANSI Standard 60 certified.
MACRO-FILL: Granular, super-absorbent, solidification and loss circulation
material. Rapidly absorbs and retains large volumes of water from aqueous
solutions, but only expands 1% in volume.
PUREGOLD CLEANDRILL: For drilling operations where clay-based drilling fluids
are restricted and a biodegradable drilling fluid is recommended. Industry standard
for use in horizontal and vertical remediation wells.
REL-PAC: Natural cellulosic, granular polymer designed for building a low-solids
drilling fluid with increased stability. Forms a tight, thin filter cake that reduces
fluid loss to the formation.
REL-PAC XTRA-LOW: Helps increase borehole stability by lowering filtrate and
fluid loss more effectively than other polyanionic cellulose (PAC) polymers. Aids
cleaning by not significantly raising viscosities and impeding flow. Helps control
reactive formations by reducing available water, and controls unconsolidated
formations by reducing whole fluid loss.
SHORE PAC: Easy-mixing, water-soluble, polymer supplied as a granular powder
designed for preparation of viscous earth-reinforcing fluids or slurries in a variety
of drilling applications.
SLURRYBOND: Powdered, inorganic mineral formula used for the solidification of
high-solids drilling slurries. Made from non-biodegradable mineral designed for
use on waste slurry that fails to pass a Paint Filter Liquids Test (PFLT).
SLURRYBOND 200: Proprietary, solid, granular, super-absorbent polymer that
rapidly absorbs and retains aqueous matter. Made from non-biodegradable
polymer designed for use on waste slurry that fails to pass a Paint Filter Liquids
Test (PFLT) or slump test.
SLURRYBOND 2000: Powdered, inorganic mineral and polymer formula used
for the solidification of high-solids drilling slurries. Made from a nonbiodegradable mineral and polymer mixture designed for use on waste slurry
that fails to pass a Paint Filter Liquids Test (PFLT) or slump test.
SLURRYBOND 2000 G: Granular, inorganic mineral and polymer formula used
for the solidification of high-solids drilling slurries. Made from a nonbiodegradable mineral and polymer mixture designed for use on waste slurry
that fails to pass a Paint Filter Liquids Test (PFLT) or slump test.

SUPER PAC: Multi-purpose, liquid polymer designed for minimizing fluid loss
to the formation. Enhances properties of bentonite drilling fluids and creates
optimum drilling efficiency through filtration control.
SUPER PAC XTRA-LOW: Low-viscosity polymer that aids in the control of reactive
and unconsolidated formations by reducing filtrate and whole fluid loss. Assists
hole cleaning in HDD work and increases penetration rates in vertical wells by not
significantly raising viscosities.
SUPER THIN: Highly concentrated additive engineered to reduce drilling fluid
viscosity and assist in settling solids. It offers immediate thinning action, reduces
gel strength and is more cost-effective than traditional thinners. NSF/ANSI
Standard 60 certified.
SUSPEND-IT: Dry biopolymer used to increase suspension and removal of larger
drilling cuttings, gravel and cobble in difficult formations. Enhances gel strength
without significantly increasing viscosity.

Drilling Mud Direct LLC, (720) 489-0300, www.muddirect.net
Barakade DWD Solidify: Effectively solidifies leftover slurry and cuttings. Allows
for disposal via dump truck instead of vac truck, reducing overall volume to be
disposed and disposal costs.
DMD Lubra Star: Our most popular liquid additive, it reduces torque and friction,
prevents sticking, lubricates many aspects of the bore, and is invaluable as an
additive for pipe pull.
DMD Power PAC L/DMD Power PAC R: Dry, polyanionic-cellulose (PAC) polymer
that improves filtrate/water-loss control and improves borehole stability. Available
in "L" grade (viscosity neutral) and "R" grade (boosts viscosity).
DMD Power XAN: Premium-quality biopolymer used as a suspension enhancer
and hole cleaning aid. Helps suspend cuttings, sand and gravel.
DMD Soda Ash: Boosts pH level of make-up water to improve bentonite mixing
and performance.
Power DET: Drilling detergent formulated for HDD. Low foaming, it helps
manage bit balling and prevents sticking tendencies of clay.
Power Swell: Plugging and sealing granular polymer that absorbs water
to swell to 200 times its original particle size. Effective LCM for HDD.
Power Thin: Clay-thinning agent, mud thinner. A liquid that helps combat swelling
clays and will also reduce the viscosity of a thick slurry. Helps manage clay problems.

CLAY-KATCH: Very-low-molecular-weight, liquid polymer with a high-cationic
charge. Used for clay inhibition instead of potassium chloride. Lower mud
densities can be achieved by causing drill solids to be enmeshed with CLAYKATCH additions, and removed with hydrocyclones and decanter centrifuge
liquid-solids separation equipment.
KEM-VIS: Medium-molecular-weight, anionic polyacrylamide in emulsion form
that is specifically developed as a viscosifier/friction reducer additive for waterbased drilling fluids. Environmentally safe, contains no alkylphenols and has a
category C toxicity classification.
KEM-THIN: Liquid thinner used to control viscosity in high-solids, high-viscosity
drilling fluids. A sulfonated copolymer in liquid form providing quick and efficient
reduction of viscosity and gel strengths in drilling fluids containing moderate
levels of calcium and salts, while subjected to high botto- hole temperatures.
Environmentally safe antiscalant featuring rapid solubility and better performance,
it is less toxic than traditional dispersants containing heavy metals. Contains no
alkylphenols and has category-C toxicity classification. Stable up to 350 degrees F.
RHEO-CLAY: Provides a high-inverted yield point (YP)/plastic viscosity (PV) ratio
for improved rate of penetration, optimum hole cleaning and greater liquid/
solids separation efficiency from hydrocyclones. It differs from sodium bentonite
(montmorillonite) by having lower cation exchange capacity and greater yield in
the presence of high hardness (Ca++ / Mg++) and sodium (Na+) values.
