Benefits of technology

The present invention is a well intervention assembly that includes a hydraulic jack assembly with an expanded work window, making efficient use of space. The modular work platforms are portable and provide a stable and secure work environment for personnel, while eliminating the need for suspended personnel. Hydraulic tongs are secured on a hydraulically operated track system, making it easy to position the tongs and move pipe. The present invention improves personnel safety by automating movement of pipe and reducing hand-to-iron contact.

Problems solved by technology

When a conventional drilling or workover rig is used to perform such operations, a well is frequently “killed” using drilling mud or other drilling fluids.
In certain circumstances, it may be impractical or undesirable to kill a well (that is, to offset reservoir pressure with hydrostatic pressure in order to put the well in a pressure-balanced state) prior to performing well intervention operations.
However, in order to perform such operations in a pressurized well system, specialized well intervention equipment is required.
As a result, snubbing units or HWU's are often viewed as a means of last resort, thereby negatively impacting the perception of such systems.
Further, such conventional snubbing units and HWU's suffer from a number of practical and operational limitations.

Embodiment Construction

[0032]FIG. 1 depicts a perspective view of a jack assembly 10 of the modular well intervention assembly of the present invention installed on an upper end of a conventional BOP assembly 100, which is itself disposed on the upper opening of a well that extends into the earth's crust. It is to be observed that modular well intervention assembly of the present invention, in general, and jack assembly 10, in particular, can be installed on any number of different well configurations. As such, the depiction of modular well intervention assembly of the present invention installed on BOP assembly 100 is illustrative only, and is not intended to be, and should not be construed as, limiting in any way. As depicted in FIG. 1, BOP assembly 100 comprises a plurality of ram assemblies 101, as well as a top flange (not depicted in FIG. 1) disposed at the upper extent of said BOP assembly 100.

[0033]Still referring to FIG. 1, jack assembly 10 of the present invention comprises substantially planar ...

Abstract

A modular well intervention assembly includes a jack assembly having increased stroke length that can be installed directly over a well or above a BOP assembly. Modular work platforms and a telescoping mast assembly can be installed and secured in place around the jack assembly. Tongs can be suspended from a hydraulically operated “track system”, eliminating the need for a conventional tong pole and spring. Pipe can be manipulated relative to the well intervention assembly using a hydraulically powered pipe handling device.

Description

CROSS REFERENCES TO RELATED APPLICATION[0001]Priority of U.S. Provisional Patent Application Ser. No. 61 / 764,075, filed Feb. 13, 2013, incorporated herein by reference, is hereby claimed.STATEMENTS AS TO THE RIGHTS TO THE INVENTION MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT[0002]NoneBACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]The present invention pertains to a modular assembly for conducting intervention operations on oil and / or gas wells. More particularly, the present invention pertains to a modular assembly for conducting operations on wells including, without limitation, work over operations and snubbing operations.[0005]2. Brief Description of the Prior Art[0006]Intervention operations have been performed on oil and / or gas wells for many years. When a conventional drilling or workover rig is used to perform such operations, a well is frequently “killed” using drilling mud or other drilling fluids. In such instances, the hydrostatic pressure exe...
