Another effort at increasing rates of penetration by taking advantage of hydraulic horsepower available at the bit is disclosed in U.S. Pat. No. 5,862,871. This development employed the use of a specialized nozzle to excite normally pressured drilling mud at the drill bit. The purpose of this nozzle system was to develop local pressure fluctuations and a high speed, dual jet form of hydraulic jet streams to more effectively scavenge and clean both the drill bit and the formation being drilled. It is believed that these hydraulic jets were able to penetrate the fracture plane generated by the mechanical action of the drill bit in a much more effective manner than conventional jets were able to do. ROP increases from 50% to 400% were field demonstrated and documented in the field reports titled �DualJet Nozzle Field Test Report-Security DBS/Swift Energy Company,� and �DualJet Nozzle Equipped M-1 LRG Drill Bit Run�. The ability of the dual jet (�DualJet�) nozzle system to enhance the effectiveness of the drill bit action to increase the ROP required that the drill bits first initiate formation indentations, fractures, or both. These features could then be exploited by the hydraulic action of the DualJet nozzle system.
FIG. 24 depicts a graph showing a comparison of the results of the impact excavation utilizing one or more of the above embodiments (labeled �PDTI in the drawing) as compared to excavations using two strictly mechanical drilling bits�a conventional PDC bit and a �Roller Cone� bit�while drilling through the same stratigraphic intervals. The drilling took place through a formation at the GTI (Gas Technology Institute of Chicago, Ill.) test site at Catoosa, Okla.
The table below shows actual drilling data points that make up the PDTI bit drilling curve of FIG. 24. The data points shown are random points taken on various days and times. For example, the first series of data points represents about one minute of drilling data taken at 2:38 pm on Jul. 22, 2005, while the bit was running at 111 RPM, with 5.9 thousand pounds of bit weight (�WOB�), and with a total drill string and bit torque of 1,972 Ft Lbs. The bit was drilling at a total depth of 323.83 feet and its penetration rate for that minute was 136.8 Feet per Hour. The impactors were delivered at approximately 14 GPM (gallons per minute) and the impactors had a mean diameter of approximately 0.100″ and were suspended in approximately 45� GPM of drilling mud.
