The DynaMic™ variable temperature motor power section has a unique, deviated stator profile designed to reduce heat generation in the power section, extending motor life in high temperature environments and extended reach wells.

Challenges Downhole

Today, many operators are forced to plan unnecessary trips to change the motor in extended reach wells. The power section’s drilling efficiency decreases with increasing temperature. Often, the tighter fit power section, which is required to begin drilling the interval, is not effective in deeper parts of the well.

As a result, customers must make multiple trips to pick up new motors with unique power sections. These trips result in excess drilling time and operations cost. The requirement for custom power sections also leads to inefficiencies and lack of tool availability for motor rental companies.

Improvement in Performance

While high temperatures elastomers help to increase downhole performance, their benefits are often limited specific temperature intervals and drilling conditions. The DynaMic power section provides an improvement in performance across a large range of downhole temperatures.

The unique, deviated stator profile in the DynaMic power section significantly reduces the heat generation in the lower end, prolonging motor life while also providing optimal power output throughout the duration of the run interval.
