Description

FIELD OF THE DISCLOSURE

[0001] Embodiments disclosed herein relate generally to stators used with positive displacement drilling motors. More specifically, embodiments disclosed herein relate to a fiber reinforced stator, and compositions for forming the fiber reinforced stator, wherein the fiber is easily incorporated and well dispersed throughout the elastomeric matrix.BACKGROUND

[0002] Moineau style hydraulic motors and pumps are conventional in subterranean drilling and artificial lift applications, such as for oil and / or gas exploration. Such motors make use of hydraulic power from drilling fluid to provide torque and rotary power, for example, to a drill bit assembly. While downhole drilling motors fall into the general category of Moineau-type motors, they are generally subject to greater working loads, temperatures, and more severe chemical and abrasive environments than Moineau motors and pumps used for other applications. As such, the demands on drilling motor components (roto...
