01/02)drilled with turbines Drill through the Silverpit and Barren Red formations with the Xtreme motor and a PDC bit Complete the section with a M4XL/Impreg combination after penetrating the coal measuresProject Results Ketch 03:The Xtreme motor drilled significantly faster than turbines(2443 ft within 77,9 hrs in two runs)One round trip was required due to a bit failure The Xtreme motor with the PDC bit drilled the coal measures(31 ft/hr)faster than the turbines(12 ft/hr)with an impreg.bit Turbines have proved unable to drill the coal measures with PDC bitsCase history for Ketch wells

SandstoneMotorvsTurbineComparisonSummaryMudMotor:Stable RPM at constant flow rateVery clear pressure indication of varying torqueVery clear indication of stallProvides more power to the bitPower output independent of mud wtGreater torque capabilitiesLower pressure drop across the tool allows higher flow rates,enhanced bit life and hole cleaningShorter lengthExcellent steerabilityTemperature limitationsProven technology(reliable)Turbine:Un-stable RPM at constant flow rateUn-clear pressure indication of varying torqueUn-clear whether stalledProvides less power to the bitPower output function of mud wtLower torque capabilitiesHigher pressure drop across the tool uses lower flow rates,reduced bit life and hole cleaningLonger lengthVery stiff poorer steerabilityHigher temperature rating(almost only reason to use)Proven technology(reliable)ThankYou
