Benefits of technology

[0016]The hydraulic pumping apparatus of the present invention is inexpensive, durable and simple to operate. Further, the hydraulic pumping apparatus of the present invention has a small footprint and can be directly mounted to wells having shallow to medium depths or, alternatively, skid supported for

Problems solved by technology

However, depending on the depth of the reservoir and density of the fluid(s), the reservoir may not have sufficient reservoir pressure to push the fluid to the surface.
However, as a well continues to produce, reservoir pressure will often decrease as a reservoir depletes.
Further, in many reservoirs, formation water will eventually encroach into the wellbore, causing the lifting requiremen

Embodiment Construction

[0038]Referring to the drawings, FIG. 1 depicts a front perspective view of support tower assembly 200 of hydraulic pumping apparatus 10 of the present invention. Elongate support tower assembly 200 is capable of being mounted to the upper end of a well that extends into the earth's crust. Said tower assembly 200 has substantially planar upper plate member 201 having optional central aperture 205, lower substantially planar plate member 202 having cut-out section 203 and elongate column support members 204 extending between said upper and lower plate members. Support tower assembly 200 provides a rigid support frame for supporting at least one hydraulic cylinder assembly 300. In the preferred embodiment, said elongate tower assembly 200 (and said at least one hydraulic cylinder assembly 300 supported therein) are mounted in substantially axial alignment over a well.

[0039]As depicted in FIG. 1, tandem cylinder assemblies 300 are mounted within support tower assembly 200. Each of said...

Abstract

A fluid balanced hydraulic pump has a support tower that can be mounted over a well. At least one cylinder assembly is pivotally mounted within the support tower. A prime mover provides hydraulic fluid to the at least one cylinder assembly through a wedge spool control valve that provides precise speed control with minimal maintenance requirements. Stroke speed can be easily and quickly adjusted without the need for expensive, troublesome or complicated electronic equipment.

Description

STATEMENTS AS TO THE RIGHTS TO THE INVENTION MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0001]NONEBACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention pertains to a hydraulic pumping unit. More particularly, the present invention pertains to a hydraulic pumping unit that provides precise rod speed control with minimal maintenance requirements.[0004]2. Brief Description of the Prior Art[0005]Liquid-producing subterranean reservoirs all have some level of energy or potential, frequently referred to as “reservoir pressure” that will force fluid (liquid, gas or a mixture) to areas of lower energy or potential. If a well penetrates such a reservoir, and if the pressure inside such a well is decreased below the reservoir pressure, fluids will feed into the well from said formation. However, depending on the depth of the reservoir and density of the fluid(s), the reservoir may not have sufficient reservoir pressure to push the fluid to the surfa...
