... and steerability of the bit. TSP cutters were placed on the gage pad to improve bit resistance against formation abrasiveness. Pre-job simulation and actual result in MDR and KLL wells showed the performance differences of these bits. The CDE 716 drilled with much higher ROP than CDE 816 but pulled out...

... kicked off in June 2019. On review of the offset wells, bit selection comprised of 4 and 5 bladed designs with 19mm PDC cutters to maximize ROP through these anticipated soft formation. After the first 19 wells were drilled, it was evident a rethink of the drilling process was required. High ROP's were...
