NEI-Drilling Motors
NEI-Drilling Motors is special developed for RSS, usually, it is longer than normal motor, the speed rate is slow but the torque is high than normal motor. It’s very suitable for direction well when use RSS.
It can provide slow speed rate (90~140rpm @ 6.75” motor) and high torque (maximum torque 14000Nm @ 6.75” motor)
Sizes: 2 7/8 – 10 1/4
Stages: As per request
Well Construction
NEI-FLOAT EQUIPMENTS
NEI-FLOAT EQUIPMENTS offers a wide range and variations of dependable Floating Equipment for application in various geologies and operating requirements. Float Equipment are equipped with various valve (s) and insert (s) as per the application. Large
flow area for higher flow rates. All equipment is PDC drillable, thereby reducing drill-out times.
High compressive strength cement is used.
Features/Benefits:
- Fast drill-out
- No metal parts-will not damage PDC bits.
- Free-floating ball abrades evenly.
- No springs.
- Operator-controlled buoyancy-regulated by Filling casing at surface.
- Cost effective.
- Available in sizes from 3 1/2 – 30

NEI-DVM-II Mechanical Stage Tool
NEI-DVM-II Mechanical Stage Tool has been designed for stage cementing operations that require the tool to be opened mechanically.
The tool features two internal sleeves that shift during the stage cementing operations. The bottom sleeve is shifted open by dropping an opening dart and allowing it to set on the opening seat.
Closing the stage collar is achieved by pumping a closing plug behind the second stage cement and applying pressure upon completing displacement.
Sizes: 4 1/2 – 9 5/8
Material: Carbon Steel / Chrome
Internal Components: PDC or Tricone Bit Drillable
NEI-DVH-II Hydraulic stage tool
NEI-DVH-II Hydraulic stage tool meets the challenges of cementing holes at any angle with a hydraulically opened port system stage tool designed specifically for horizontal completion.
It is specifically used for Primary cementing in deep vertical or high deviated horizontal-well conditions. It reduces total hydrostatic pressure on weak formations to prevent lost circulation during cementing. Clear surface indications of opening and closing pressures provide safer and more efficient operations. The opening pressure of the stage tool can be adjusted at rig site to meet well requirements, providing operational flexibility.
Sizes: 4 1/2 – 9 5/8
Material: Carbon Steel / Chrome
Internal Components: PDC or Tricone Bit Drillable
