An expandable tubular liner includes a first tube, a second tube, a mechanical coupling for coupling the first and second tubes, and an insert coupled to the mechanical coupling. The insert is capable of forming a metallurgical bond with at least one of the tubes when energy is injected into the insert.

Expandable connection

Radial expansion system

Expandable tubular

A method of testing a tubular member and selecting tubular members for suitability for expansion by subjecting a representative sample the tubular member to axial loading, stretching at least a portion of the tubular member through elastic deformation, plastic yield and to ultimate yield, and based upon changes in length and area calculating an expandability coefficient indicative of expandability of the tubular members and selecting tubular members with relatively high coefficients indicative of good expandability.

A self-lubricating expansion mandrel includes a system for lubricating the interface between the self-lubricating expansion mandrel and a tubular member during the radial expansion of the tubular member.

Self-lubricating expansion mandrel for expandable tubular

A lubrication system for lubricating an interface between one or more expansion surfaces of an expansion device and one or more interior surfaces of a tubular member during a radial expansion of the tubular member using the expansion device.

A method of forming a wellbore casing within a borehole that traverses a subterranean formation, is provided by assembling a tubular liner by coupling a multi-layer tubular insert assembly to a threaded portion of a first tubular member, and coupling a threaded portion of a second tubular member to the threaded portion of the first tubular member and the multi-layer tubular insert. The tubular liner assembly is positioned within the borehole; and the tubular liner assembly within the borehole is radially expanded and plastically deformed. The multi-layer tubular insert includes a first tubular insert having a first modulus of elasticity; and a second tubular insert coupled to the first tubular insert having a second modulus of elasticity. The first modulus of elasticity is different from the second modulus of elasticity.

A method of forming a wellbore casing within a borehole that traverses a subterranean formation includes the steps of assembling a tubular liner by coupling a threaded portion of a first tubular member to a threaded portion of a second tubular member and coupling a tubular sleeve to the threaded portions of the first and second tubular members. The method further includes positioning the wellbore casing within the borehole and radially expanding and plastically deforming the wellbore casing assembly within the borehole. The step of coupling the tubular sleeve through the threaded portions of the and second tubular members includes applying impulsive magnetic energy to the tubular sleeve.

The present invention provides a protein polymer material and a method for preparing the protein polymer material involving applying an energy such as electrical energy or gravitational energy to a protein to cause the protein to assemble in a controlled arrangement. The protein used in this method may be any suitable fibrillar protein capable of self-assembling.

A surface capacity parameter is determined for a surface of an article having irregularities therein that can be characterized by peaks and valleys relative to a reference point. Initially, an area of interest on the surface of the article and a lateral resolution of that area of interest are determined. An apparatus generates a visual representation of the area of interest on the surface of the article. A deflection contact part factor for the article is calculated, and a bearing ratio curve level is determined based upon the calculated deflection contact part factor and the magnitude of the height or distance between the tallest peak and the lowest valley on the surface of the article. The volume of the material comprising the peaks in the surface of the article and the volume of the space in the surface of the article that is available for the retention of a fluid, such as a lubricant, are determined. Lastly, a surface capacity parameter is calculated as the ratio of the volume of the material comprising the peaks in the surface of the article to the volume of the volume of the space comprising the valleys in the surface of the article.

Method and apparatus for measuring, analyzing, and characterizing irregularities on a surface of an article

A method for measuring irregularities on the outer surface of an article employs an apparatus to obtain qualitative information regarding a first portion of the outer surface of the article, which can be used to generate a visual representation of a first portion of the outer surface of the article. Then, the article is moved by a predetermined amount, and the apparatus is again used to generate a visual representation of a second portion of the surface of the article. This process is repeated to obtain a plurality of visual representations that together span across a predetermined amount of the surface of the article. Then, the plurality of visual representations are processed to generate a single comprehensive enlarged visual representation of a relatively large surface area of the article, which is preferably shaded, colored, or otherwise highlighted to illustrate the irregularities that are formed therein. The single comprehensive enlarged visual representation can be used to analyze the nature of such irregularities.

An apparatus for manufacturing a case hardened journal cross includes an inductor having an open side to allow the journal cross to be inserted and withdrawn from the induction process with relative ease. The conductive frame of the inductor is shaped in a cross-like pattern that outlines the outer perimeter of a journal cross on each side of the journal cross. Because the induction coil passes across both sides of the journal cross, heat treating may be enhanced at specific locations of the outer surface of the journal cross by adjusting the distance of the induction coil from the journal cross. Also, a method for manufacturing such a journal cross includes determining the maximum stress distribution for the journal cross and, based thereon, determining the desired depth and location of the case hardening. The depth of the case hardening throughout each of the trunnions is calculated based upon the stress distribution as being greater than or equal to one-fourth of the outer diameter of the trunnion less the inner diameter of the lubrication passageway formed through the trunnion. A heat treatment is performed using the apparatus described above to achieve the desired case hardened layer throughout the trunnion.

A structure and method of manufacturing an outer surface of a shaft avoids the creation of a preferential lead and thereby minimizes leakage through an annular seal assembly when such shaft is rotated or otherwise moved relative thereto during use. The outer circumferential surface of the shaft is formed having a plurality of relatively small irregularities that are evenly distributed thereabout. Such irregularities may be defined by relatively higher portions and relatively lower portions that are formed in an intersecting, cross hatched pattern or in a circumferentially extending undulating or oscillating pattern. To form the cross hatched pattern, an apparatus can be operated to engage the outer circumferential surface of the shaft in two sequential passes in opposite axial directions while the shaft is being rotated. To form the undulating pattern, an apparatus can be operated to engage the outer circumferential surface of the shaft in an axially reciprocating manner while the shaft is being rotated. By varying the feed rate of the apparatus, the rotational speed of the shaft, and the magnitude of the force applied by the apparatus against the outer circumferential surface of the shaft, the size, shape, and depth of the surface irregularities can be varied as desired.

A method for joining ductile iron with steel includes the steps of depositing a metallic material between a first ductile iron component, and a second steel component. The joint formed by the method has an interface disposed between the two components and the first and second components are welded thereto. The interface includes the metallic material.
