Paper presented at the SPE Asia Pacific Oil & Gas Conference and Exhibition, October 17–19, 2022
Paper Number: SPE-210624-MS
... In general, there were two different designs run in KLL and MDR wells, shown by Figure 3 . The first bit design was seven-bladed bit with 16 mm PDC cutters as the leading cutting structures and 14 mm conical diamond element placed behind those cutters (CDE 716). The CDE were placed strategically...

... with several existing offset wells using a 12¼-in., five-bladed, 19-mm (519) drill bit design, and a concept bit developed using 25-mm diameter cutters while maintaining comparable ancillary features. This was tested in the same field on both vertical and S-shape sections using the same bent-housing motor...

... cutters in XX development wells in offshore Sarawak. Based on historical drilling data from offset wells around the XX Field, multiple bit trips were required on each section from 17-1/2" until 8-1/2" holes. Various bit manufacturers had come up with several bit designs to drill this field. Post-run bit...
