Abstract: A downhole releasable tubing connection includes a joint between two tubing strings, wherein one of the two tubing strings is radially expanded and plastically deformed by an expansion device. When the expansion device is moved adjacent to the joint, a mechanism in the joint reacts to the radially outward forces of the expansion device and releasably expands, separates, breaks, or otherwise provides a release between the two tubing strings. One tubing string and the expansion device can then be removed to the surface of the well bore while the expanded tubing remains installed in the well bore.

Abstract: Aspects of this invention include a method for deploying a small diameter submersible pump in a deviated wellbore. The submersible pump is first lowered into the production tubing under the influence of gravity. The pump includes a sealing member deployed thereabout which provides a releasable seal with an interior surface of the production tubing. The pump is then forced deeper into the production tubing (e.g., into a deviated section of the wellbore). This is accomplished via introducing a column of liquid (such as water) into the production tubing above the pump. The liquid exerts a force on the pump and sealing member so as to force the pump deeper into the well, thereby drawing one or more power lines into the wellbore with the pump. The invention advantageously enables a small diameter submersible pump to be economically deployed in a highly deviated wellbore. The invention also advantageously enables deployment into partially obstructed and/or damaged tubing.

Abstract: A bottom hole assembly in a casing-while-drilling operation is retrieved by displacing the fluid in the casing string with a less dense fluid than the fluid in the annulus.

Displaced fluid flows out of the casing string and through a restrictive orifice of a choke. The flow area of the orifice is varied as the bottom hole assembly moves upward to control the rate at which the bottom hole assembly moves upward.

Abstract: A tool for extracting well pipe casings resembles an enlarged pipe-thread tap. The tool is designed to be suspended under and driven by the traveling rotary table and hydraulic vertical drive system of a conventional drilling rig. By this means, well pipe casings are withdrawn from wells by engaging the tops of such well pipe casings, and unlike the prior art, which grapples well pipe casings at their very bottom, and at the end of a cable. Unlike withdrawing casing by a cable pull, wherein cables stretch and unstuck casings might launch like projectiles, the extractor tool manages to withdraw well pipe casing in a recoilless manner, which is more controlled, and safer.
