Extreme power downhole drive for RSS assist

General Description

Positive displacement motor (downhole drilling motor) is designed for driving the bit downhole adding more RPM and torque to be able to cut formations more efficiently and faster.

Motors can also be used for workover and well cleaning operations, as well as coil tubing and through tubing applications.

SDT company is capable to manufacture all the motor sizes, however our initial focus is to design and develop most robust and efficient slim size motors ranging from 2 7/8” to 5” size including RSS assist applications.

Features & Benefits

High-quality materials for the manufacture of all parts and components

Reinforced axial multi-row bearings

Heavy duty drive shaft of in-house design

Proprietary in-house developed rubber compounds from leading manufacturers with highest properties

Use of high quality adhesives

Most cost effective motors available on the market
