With the rapid development of coiled tubing drilling techniques, downhole motors have become increasingly compact for well drilling and repair applications. Small diameter downhole motors designed for coiled tubing operations are gaining prominence in well repair, micro-borehole drilling, side drilling, and re-drilling of existing wells.

Since coiled tubing cannot rotate during drilling operations, compact downhole motors serve as an optimal solution for downhole drilling tools in coiled tubing applications and well repair scenarios. These motors are widely used in operations including well flushing and sand cutting.

Beyond coiled tubing applications, these compact downhole motors are also utilized in radial drilling operations.
