Water-based fluid

A clay-free system Designed for maximum shale inhibition

in highly reactive formations

Helps eliminate or reduce many

problems caused by gumbo-like clay

Stable up to 163oC, with good return

permeability data (>86%)

Developed in response to the need for a WBF

that would approach the operationalperformance of invert emulsion fluids

For use in environmentally sensitive areas

Helps minimize low gravity solids content

Colloidal solids are commercially flocculated

and removed (SCE>85%)

The unique polymer combination provides

a well lubricated gauge wellbore

Solutions to Reactive Clays & Shale

Minimum requirements for a high performance water-based mud:

Low colloidal content Highly inhibitive

Non-dispersed Shear thinning rheology

The HYDRO-GUARD

system is created

by combining the

following polymeric

encapsulators.

Each component

targets unique clay

types producing a

near gauge wellbore.

HYDRO-GUARD

High Performance Inhibitive Water-Based System

Replacement for Invert in Environmentally Sensitive Areas

CLAY SYNC

Linear Swell Kit:

The linear swell meter (LSM) system isused to determine shale hydration or

dehydration by measuring the increase

or decrease in length over time of

reconstituted or intact shale cores.

Capillary Suction Timer:Measures shale hydration and dispersion

properties by simulating the shear and

chemical forces of drilling. Shale-solids

content and mixing time are fixed, with

chemical characteristics such as pH

and salinity providing the variables.

Malvern Mastersizer 2000:Accurately determines particle size of test

specimens from 0.02 2000 micrometers.

SpecialtyTesting & Procedures

With the development of high performance water-base fluids (HPWBM)

comes the need for additional testing. Along with the ongoing monitoring of

standard properties, colloidal content and active inhibitor product concentrations

can be monitored while the well is being drilled. In the pre-planning phase,

studies can be conducted on the clay and shale to be drilled, using industry

recognized tools that give reliable performance measurements. This data is

collected via several instruments. One example is the Hand Crank Centrifuge

(not pictured). Other examples are shown below.

PA Test Kit:Attached to the standard HPHT

cell, this device allows for accurate

determination of CLAY SYNC shale

stabilizer and CLAY GRABBER

flocculant concentrations in the

active drilling fluid.
