Baker Hughes, a GE company (BHGE),recently introduced the Navi-Drill DuraMax motor, which deliver increased power to the drill bit for higher rates of penetration (ROPs). In a recent application in North Dakota’s Williston’s Basin, the motor was used to improve drilling time by 40% and increased rate of penetration (ROP) by 35%. In this video with Thomas Jaeger, Senior Product Manager for Drilling Motors with BHGE, at the 2019 SPE/IADC International Drilling Conference on 5 March in The Hague, Mr Jaeger discusses the motor’s development and key features that distinguish it from others on the market.
Navi-Drill? DuraMax? motors provide increased reliability and durability for longer runs and extended laterals—letting you drill the curve and lateral in one run.
The motors high weight-on-bit (WOB) and flow-rate capability help it deliver increased horsepower and torque for faster penetration rates. And, these motors deliver that increased power to the drill bit while minimizing the energy needed to drill—helping you reach total depth with maximum speed and efficiency.
This latest-generation of high-performance positive displacement motors has been completely redesigned by BHGE engineers using state-of-the-art technology. The redesigned motors’ short bit-to-bend configuration allows higher build-up rates while delivering superior WOB and durability. The simulation-driven design also enables predictive maintenance, mitigating motor failures and reducing non-productive time.
Push your drilling limits with a stronger lower end and power sections that deliver 15% greater torque. The higher flow rate range permits more options when it comes to RPM, leading to 40% more horsepower at the bit. And, you can run with less differential pressure while still achieving desired? penetration rates. This new motor platform delivers the output you need to maximize your drilling performance.
Navi-Drill DuraMax saves customer 3 days of rig-time in the Permian Basin
An oil producer in the Permian Basin of west Texas, USA, contacted Baker Hughes, a GE company (BHGE), to help provide a solution that would reduce the amount of time spent in drilling curve and lateral hole sections. The wells in this area typically require a steerable motor with a highadjustable kick-off (AKO) setting to achieve the build-up rate (BUR) necessary to drill the curve section. However, a high AKO setting can compromise the rate-ofpenetration (ROP) in the lateral section.
The BHGE team recommended their new Navi-Drill? DuraMax? steerable drilling motor to improve performance and reduce the number of trips made for new motors and bits through the curve and lateral sections. The ruggedized DuraMax motors, with a shorter bit-tobend, successfully drilled the high BUR curve section. The rugged motor design also enabled the operator to rotate the drill sting at a higher RPM and a high weight-on-bit (WOB), compared to offset runs, and delivered optimized performance in the lateral section.
The 5-?-in. Navi-Drill DuraMax D75- 5095C motor drilled the 6-?-in. curve and lateral section in the Wolfcamp A formation. The DuraMax motor drilled 7,652 ft (2,332 m) in 80 drilling hours and maintained an average ROP of 114 ft/hr (35 m/hr). The motor delivered a consistent BUR in the curve, exceeding expectations. By drilling 3,127 ft (953 m) laterally in one day, BHGE provided a 30% improvement in overall ROP, which saved the customer 3 days in rig-time。
Navi-Drill DuraMax improved drill time by 40% and ROP by 35%
An operator in North Dakota’s Williston Basin was developing a lateral Three Forks well. Drill bit consumption was reducing performance, with 8 drill bits damaged on 14 previous wells. Baker Hughes, a GE company (BHGE), had been using the BHGE 5-in. Xtreme eXtend motor with various bits with reasonable success but experienced moderate vibration levels, impacting measurement while drilling (MWD) reliability.
The BHGE team decided to use its new 5-?-in. Navi-Drill DuraMax? motor with the BHGE Dynamus? drill bit to reduce vibration and improve production and ROP. This proved to be a winning combination. The team completed the lateral section 2 days faster than with offset wells, a 40% improvement. This combination also helped to reduce the vibrations by 20% to help complete the section in a single run.
BHGE drilled a 6-in. lateral of 10,294 ft (3138 m) in 46.3 drilling hours?a record performance?on the first attempt. The total time from the pick-up to the laydown of the BHA was 3.3 days. This compared favorably to the operator’s average Three Forks well time of 5.2 days and 68 hours per 10,000 feet (3048 m) drilled. Drilling days were reduced by 40% and ROP increased 35%
