... WOB as the minimum WOB needed to fully engage all cutters on the bit and maximize depth of cut. The efficient WOB changes with both bit state and formation strength, so an indication of bit wear can be used to predict formation strength. Deployment of the bit dull grade predictor enables...

... was necessary for the drilling operation to address the dull conditions, maintain a competitive rate of penetration (ROP), provide smooth borehole quality, and maintain low vibration levels. A new PDC bit was designed using patented multilevel force balancing technology: a new theory of PDC cutter layout...

... The mechanical cutter tool was run in hole to 6,717 ft depth before correlating and positioning the tool at 6,565 ft. The well was then pressured up to 22 bar and the cut performed flawlessly, or as the operator stated, quote: “A cut worthy of a King!” Results Cutting time: 3 hrs Complete wireline...
