WILLIS, Texas – R&M Energy Systems has unveiled the Moyno ERT Power Section, an even rubber thickness stator that improves the overall performance of power sections used in downhole drilling applications.

R&M Energy Systems’ experience in stator engineering, manufacturing, and product application enabled the development of stators with internal contours that are precision-machined, rather than hydraulically formed. The resulting tubes feature durability and tolerance that optimizes the benefits of even rubber thickness technology, the company says.

Applying an even thickness of rubber to the stator contour and supporting each lobe with steel minimizes the rubber’s degree of dimensional change during use due to temperature, chemical attack, and loading. This design allows Moyno ERT Power Sections to reliably produce up to 100% more power output compared to conventional stators. For the user, this higher power density and improved reliability translate to higher ROPs, the company says.

An additional benefit of the ERT’s high power density is the ability to use shorter power sections with performance outputs comparable to that of longer conventional product. This can improve the motor’s directional response as well as MWD and LWD measurement quality by placing their sensors closer to the bit. Moyno ERT Power Sections can also be used to drive RSTs.
