... Bit "A" (left) and Bit "B" (right). Both bits were 216 mm diameter and used 16 mm diameter PDC cutters. Fig. 13 Bit "A" in configuration 1. This bit was previously run in the field, so it had a dull condition representative of normal running conditions. The rightmost image shows cutters...

.... The client saved multiple trips of PDC bit runs and drilled 50% farther, double rate of penetration (ROP) than the best PDC bit run in the offset wells. The revolutionary bit cutter design works well regardless of any hole size and BHA configuration. This study will present an analysis of the drilling data...

...Historical Performance The 6" hole sections on 49/22-N2z and N3 wells were drilled utilising turbine and conventional PDM technology combined with diamond impregnated, PDC and TCI drill bits. On the N3 well a variety of assembly stabilisation configurations were utilised depending...

... Abstract A polycrystalline diamond compact (PDC) bit was used to drill a northern Kuwait well. The typical casing design for this field calls for the 16-in. section to be the longest section in the well, which extended from 1,230 ft to 6,000 ft for a total of 4,770 ft in this particular well...
