- Oil & Gas Drilling Test Program
- A number of tests have been
undertaken in the United States on rock drilling
equipment. While the tests are incomplete in that they are still to be conducted in all mediums of ground
makeup, the tests have given an
excellent insight into the improvements effected by treatment with the COLDfire Thermal Cycling process.
- Testing is currently being conducted
in both land and offshore Oil and Gas
mining in the United States, Desert Oil mining in the Middle East and Underground Gold mining in
- The rock drilling bits tested and
reflected in the initial results all have rotating sealed bearings with
Tungsten Carbide bits and cutters embedded
into the OD of the rotating heads. All the bearings are all of Timken design.

- Control Drills were changed after
drilling was completed.
- *The COLDfire treated drill was used
to drill a further 1620 feet in a 12 hour shift
of Test Protocols
- With the
second use of the treated drill to another 1610 feet on a second
well that was started at 2000’, below the profile depths of rock
shale and sand formations so no direct comparison or conclusions of
wear or penetration rate are valid to the tests. However, it is a
significant factor that we drilled a total of 3955 feet between both
wells with little deterioration in the exterior appearance of the
bit (i.e. no buttons missing and in gauge).
- Given the
performance of the treated carbide bits bettering the performance of
the diamond bits we would like to conduct further testing with a set
of diamond bits.
Natural Gas Drilling bits are more basic in design and are used to
hammer as well as turn as they are pushed into the ground. They are
also designed with
carbide buttons on the heads to improve their wearability.
