Benefits of technology

The present invention relates to a rigless well intervention apparatus and method for performing various well workover and intervention operations. The invention provides a way to conduct well interventions without the need for a rig, which can save time and money. The invention can be used in a variety of well completion processes, such as drilling, snubbing, and well workover operations. The invention also includes a method for setting up and rigging down the equipment required for the well intervention operations. Overall, the invention allows for more efficient and cost-effective well interventions.

Problems solved by technology

A well that is not producing to its full potential may require service or workover.
Casing can be damaged by corrosion, abrasion, pressure, or other forces that create holes or splits.

Embodiment Construction

[0041]The rigless intervention apparatus of the present invention is a substructure frame created to handle pipe and perform many and varied well workover and intervention operations. Such operations can pertain to a range of products, services and techniques associated with running or pulling pipe, or alternately, associated with the servicing or repair of the production tubing or other aspects of an oil or gas well. The rigless intervention apparatus of the present invention is especially adapted for running or pulling pipe on salt leaching, geothermal, or suspended wells.

[0042]The substructure frame of the rigless intervention apparatus and method of the present invention includes hydraulic jacks and strain gauges for accurately controlling the positioning and movement of the pipe or other well components.

[0043]The rigless intervention apparatus of the present invention provides a moveable framework adapted for movement mechanically, hydraulically, using any type of fluid pressur...

Abstract

The present invention relates generally to a rigless well intervention apparatus and method for well completion, recompletion, servicing, workover and intervention. Specifically, the present invention relates to a rigless well intervention apparatus and method for performing various well completion, recompletion, servicing, workover and intervention operations that pertains to a range of products, services and techniques whether designed to be run through, or conducted within, the production tubing of an oil or gas well, or not, ranging from the ability to operate within a restricted diameter tubular with live-well intervention when the tubing is in place to the ability to drill the well.

Description

FIELD OF THE INVENTION[0001]The present invention relates generally to a rigless well intervention apparatus and method. Specifically, the present invention relates to a rigless well intervention apparatus and method for performing various well workover and intervention operations that pertains to a range of products, services and techniques designed to be run through, or conducted within, the production tubing of an oil or gas well ranging from the ability to operate within a restricted diameter tubular with live-well intervention particularly, for running or pulling pipe on salt leaching, geothermal or suspended wells.BACKGROUND OF THE INVENTION[0002]Oil well completion is a generic term used to describe the assembly of downhole tubulars and equipment required to enable the safe and efficient production from an oil or gas well. The point at which the completion process begins may depend on the type and design of the well. However, there are many options applied or actions performe...
