It is generally known that rate of penetration (ROP) is one of main factors having an influence
on cost-performance characteristics of drilling. The Near Bit Ejector Unit (NBEU) is an efficient device for drilling rate increases. It can improve the bottomhole flow field and make full use of
hydraulic power to crack the formation. It can be used on rotary drilling, on drilling with PDM and on turbine motor drilling. It is an anti-balling device. We can guarantee that by fulfillment
of our technology you can increase the rate of penetration (ROP) and bit footage from 40% and more. These factors help reduce the timetable, capital and power inputs.
Advantages of NBEU:
1. The
rate of penetration (ROP) is increased
2. Drilling time is decreased
3. Saving
of bits quantity and trips for bit’s replacement
4. Bits
status: suitable for further use.
