Shur-Drill

Shur - Drill^®

SHUR-DRILL is a unique proprietary liquid polymer designed for use in rotary drilling and horizontal directional

drilling operations. It conditions drilling fluids to control fluid loss, prevent formation clays from swelling, and will

keep tools clean by preventing bit balling. Unlike many commonly used polymers, SHUR-DRILL actually aids in

the effective operation of solids control equipment by dropping silts and sands from the fluid. Similarly it is tolerant

of brackish and harsh water conditions which adversely affect many other polymers. SHUR-DRILL is environmentally

safe and non-fermenting.

SHUR-DRILL ADVANTAGES:

Safe: Non-polluting, Non-fermenting

Controls fluid loss

Coats and inhibits clays

Builds viscosity

Mixes easily

Performs in saline environments

Reduces friction — drag and torque

3 EASY STEPS FOR EFFECTIVE DRILLING FLUIDS:

(1) Treat make-up water with soda ash to a pH of 8 to 9. (2) Add bentonite product― HIGH YIELD BENTONITE or

TRU-BORE. (3) Add SHUR-DRILL.

In air-drilling operations, SHUR-DRILL can be added to stabilize shale and clay formations. Add 1 pint per 100

gallons of water upstream from SHUR-FOAM or SHUR-FOAM II injection.

Below are typical application rates for SHUR-DRILL^® and other products for use in certain drilling conditions.

For 500 Gallons of Make-up Water: Add approximately ¼ pound of soda ash to bring water a pH of 8 to 9 In any

fluid, always add bentonite products before adding the polymer.
