The Mud Cooling International Inc. Cooling System can be
used in any Application where drilling safety or efficiency is
enhanced by cooling the drilling fluid, such as:
• Maintaining circulating temperatures below formation
temperature to prevent thermal hole sloughing and to
maximize hole stability while drilling long-reach horizontal
heavy oil and/or SAGD
• Lowering the circulation temperature in deep, high temperature foothills
wells to lower mud costs and reduce potential operational problems with
bits, motors and down hole tools
• Lowering the circulation temperature in deep, high temperature
geothermal drilling

Case Study – CFO Forest Mount Coty 2K-02
In 2003, Canadian Forest Oil
(CFO) drilled the second
deepest on land well in the NWT,
approximately 4,500 meters.
The well, 2K2, is located in the
SW corner of the NWT near the
community of Fort Liard in an
area know for hot temperatures.
During the well planning phase
CFO approached Impact Drilling
about the drilling fluid cooler’s
ability to reduce high
temperatures.

8. Drilling Fluid Cooler Results
• Bottom Hole Temperature increased 29% from 135 to 190 degrees
over the approximate 1,500 Meters the Impact Drilling Fluid Cooler
was active in the Drilling Program

Drilling Fluid Cooler Results
• During the entire Drilling Program, Cooler Temperatures Out
are consistently 22 Degrees Celsius above the Ambient Air
Temperature
• Increases in Bottom Hole Temperatures failed to increase
the temperature of Cooled Drilling Fluid

Drilling Fluid Cooler Results
• During the entire Drilling Program, Shaker Temperatures are
consistently within 20 Degrees Celsius of Cooled Drilling
Fluid
• Increases in Bottom Hole Temperatures failed to substantially
increase the Temperature of the Drilling Fluid demonstrating
the effectiveness of the Drilling Fluid Cooler system

Drilling Fluid Cooler Results
• Safety – Reduction of Shaker Temperatures creates a Safer
Environment for Floor Hands and Mud Engineers who are
working with 60 Degree Drilling Fluid
• Drilling Fluid Life – Reduced Temperatures increase the life
and overall cost of expensive Oil Based Drilling Fluid
• Directional Tools – Reduced Temperatures increase the
life and accuracy of Directional Drilling Equipment
