Particle Impact Drilling (PID)
Technology
The patented Particle Impact Drilling (PID)
technology is a mobile system that readily adapts to
typical conventional drilling rigs. The system will be
provided and operated by PDTI as a service to the oil
and gas company for drilling certain rock intervals;
specifically in wells where penetration rates decrease
due to extreme compressive strength of the formations
being drilled. Tests have shown that the PID
system is capable of drilling through rock formations at
rates multiple times faster than current conventional
techniques.
The system relies on readily
available hydraulic energy combined with round hardened
steel particles entrained in the drilling fluid to
rapidly excavate the rock formation being drilled.
Unlike conventional drilling techniques, the process
does not rely on weight-on-bit and torque to
mechanically break the rock. Steel particles are
introduced into the drilling fluid at a point downstream
from the rig pumps, thus not interfering with the normal
operation of the rig pumps. These particles then flow
down the drill stem and are accelerated through the
nozzles of a specially designed fixed-cutter bit,
striking the formation at high velocities. The particles
and cuttings are circulated to the surface by the
drilling fluid where a shot-extraction device captures
the particles for re-injection. The PID application
results in significant rate-of-penetration gains,
thereby reducing the amount of time the operator spends
on location to drill the well. Value is generated by
savings in labor, fuel, rentals, rig time and other
variable well costs, resulting in a much more efficient
and cost-effective drilling process.
The PID system is protected by U.S. Patents 6,386,300
B1 and 6,581,700 B2. Other U.S. patents and
foreign patents are pending.
The
reduction in drilling time and reduction of other
drilling problems resulting from the utilization of the
PID system represents estimated savings between 35% and
50% of conventional drilling costs.
