...°. The highly abrasive formation is causing inconsistent PDC bit performance while drilling the 5 7/8-in. horizontal section resulting in exceeding the authorization for expenditure (AFE) of the wells. Saudi Aramco, in collaboration with the bit company, analyzed the field data, which showed extensive cutter...

... assembly required steadily increased force to drive the cutter the same distance. Examination of the rolling cutter's dull condition clearly indicated significantly improved durability and cutting efficiency. The recent introduction of a new rolling cutter PDC bit that utilizes the entire 360° of diamond...

... With laboratory testing of single CDEs complete, the next challenge was to determine how to incorporate the element into a PDC cutting structure. The study focused on a conventional PDC bit's problematic center cutting structure, or cone area which presents several distinct design challenges...

... Abstract The introduction of new, wear-resistant polycrystalline diamond compact (PDC) bit cutter technology in recent years has dramatically increased the demand for increased torque output from the positive displacement motor (PDM). The commercial introduction of pre-contoured (i.e...

... of this technology, several new design features were successfully tested in Sultanate of Oman in traditional PDC applications. Once the new technologies were fully developed, an effort was made to test these PDC bits in historically non-PDC drillable applications. One of the first applications identified...

... of tripping, as well as lower rates of penetration (ROP) as a result of vibration. Conventional positive displacement motors (PDM) were typically used in this offshore application. Polycrystalline diamond compact (PDC) bits were run with the PDMs because of their longer life and increased ROP through...

... Abstract Historic performance in slim hole rotary steerable (RS) applications in the Middle East was held back by severe torsional and lateral vibration issues. A new family of slim hole polycrystalline diamond compact (PDC) bit designs, specifically matched to the rotary steerable systems (RSS...

... requiring three PDC bits to complete the section subsequent to the roller cone run. The main challenge has been the highly abrasive Zubair formation with UCS in the 12,000–15,000 psi range. Traditionally, drilling abrasive formations with PDC has been challenging even in smaller hole sizes (8-1/2" etc). 2...

... a polycrystalline diamond compact (PDC) drill-bit/mud-motor combination for use on Russian-made rigs to achieve performance improvement. Issues included tool face control, initial cost of PDC drill bits, and in-country rigs incapable of delivering adequate torque and hydraulic horsepower to the PDC bit. Applied...

... of pyrite in the top Zubair. The Zubair is usually drilled with average 3–7 insert bits which quickly dull and lose gage, requiring many trips to change bits. For RA-206, the enhancement introduced to this section was the first successful PDC bit application of drilling Zubair in Kuwait, and which...

.... Due to the collaborative effort, the operator completed the demanding 16" hole section for the first time in one run using the new BHA/PDC bit combination. The application of this new technology has reduced cost/foot from $195.84 to $121.59 for a total saving of $365,681 over 4,925 ft and 226 drilling...

...Drilling Objectives After conducting a field study, the team of engineers from Saudi Aramco and the service company began the process of addressing the directional challenges. Roller cone bits and PDC bits were benchmarked. For TCI the average performance per bit was 380 ft at 12.4 ft/hr...
