Abstract: Systems and methods for providing a hydraulic lift device for use in producing a subterranean well. In some cases, the hydraulic lift device includes a hydraulic cylinder having a first cylindrical sleeve slidably coupled to a second cylindrical sleeve, wherein the first and second sleeves define a hollow channel to accommodate passage of a polished rod. In some cases, the first cylindrical sleeve includes a surface for securing a portion of the polished rod. Additionally, in some cases, the lift device includes a port in fluid communication with the hollow channel, wherein the port is configured to receive an inlet line from a hydraulic pump. In some cases, the lift device also includes a guidance system disposed at least partially outside the hydraulic cylinder, wherein the guidance system is configured to prevent axial rotation of the first cylindrical sleeve with resect to the second cylindrical sleeve. Other implementations are described.

Abstract: Systems and methods for providing a pump driving unit for driving an above ground pump. The pump driving unit utilizes a single prime mover and a drive train for actuating multiple components required to drive the above ground pump. Some implementations of the pump driving unit include phase separation devices, filtering units, and cooling units that may also be actuated by the drive train of the unit. Some implementations of the pump driving unit further include an enclosure and a platform for containing the unit and simplifying on-site installation.
