Latest Patents

Rohling holds a patent for a "Wellhead with hydraulic pump actuator." This wellhead assembly is particularly suited for oil wells and features a wide working pressure range. It employs three components that fit together to seal the well casing, hold the tubing against high wellhead pressures, and provide a connection to the tubing through which the sucker rods are operated. The primary casing seal is formed by the mating contact of metal surfaces that are not subject to deterioration. The actuator for the subsurface pump is a vertically disposed hydraulic cylinder unit aligned with the sucker rods, forming the uppermost section of an elongated cylindrical housing. This housing also includes a lowermost section on the wellhead that provides the outlets for the fluid pumped from the well, and an intermediate control section that contains a spool valve for controlling the hydraulic actuator. The spool is shifted by the piston and rod of the hydraulic actuator at the upper and lower limits of their stroke to reciprocate the sucker rods and operate the subsurface pump.
