Paper presented at the IADC/SPE Drilling Conference and Exhibition, March 1–3, 2016
Paper Number: SPE-178765-MS
... the CDE's thick diamond table essentially doubles its impact strength and provides approximately 25-30% more wear resistance compared to a conventional premium PDC cutters ( Figure 5 ). These properties suggest CDE bits have vast potential to improve run lengths and penetration rates in impact-prone...

Paper Number: SPE-178822-MS
... From the introduction of CDE bits into the TF1 application in October 2014 to March of 2015, 15 different operators in the Williston Basin combined to use CDE for a total of 116 runs. During the same time span, 528 conventional PDC bit runs from the top three bit companies in the basin took place...

... exercise, modeling confirmed the balanced profile equates to less lateral force per cutting element on CDE bits compared to conventional PDCs mitigating shock and vibration ( Figure 9 ). The increased bit/BHA stability would translate into higher ROP and footage totals while prolonging the operating life...
