    Abstract: A method of repairing tubulars downhole is described. A swage is secured to a force magnification tool, which is, in turn, supported by an anchor tool. Applied pressure sets the anchor when the swage is properly positioned. The force magnification tool strokes the swage through the collapsed section. The anchor can be released and weight set down on the swage to permit multiple stroking to get through the collapsed area. The swage diameter can be varied.

    Abstract: A downhole debris filtering apparatus has the flow diverter retracted as the tool is run in. Settling velocity is the rate at which debris will fall through the fluid. Settling velocity is dependent on the density of the fluid and the debris density. If the fluid velocity exceeds the settling velocity, the debris will rise. The restricted annular area outside the screens raises the fluid velocity. Above the cup sleeve, the annular area increases significantly and the fluid velocity is reduce to below the settling velocity to allow debris to settle to the bottom of the tool. On run in, the fluid merely bypasses on the outside of the filter. Large debris will settle into the tool as described. When pulled out of the hole the swab cup/flow diverter is actuated into casing or liner wall contact and a large passage is opened to allow flow though the filter. Small debris that has risen above the tool will be captured as the fluid is filtered through the screen. Another embodiment with a non-retractable cup uses a sliding sleeve valve with a large open area.

    Abstract: A method for applying cutting elements to a tool for cutting or milling a metal item in a well is disclosed, along with the cutting element used in the method. The tool can include one or more blades extending outwardly or downwardly from the tool for cutting a metal item such as the wall of a casing string, or for removing a predetermined length of a casing string in a cutting action. The blade or blades have cutting elements positioned on the leading faces of the blades to engage the casing string or other metal item in the bore hole. Each cutting element is composed of a plurality of effective cutting faces. Each cutting face can have a substantially triangular shape, or a substantially square shape, or some other geometric shape. The cutting elements can be arranged in a random pattern. Each cutting element can be oriented in a random orientation relative to the blade. The cutting elements are shaped so that, regardless of the positioning or orientation of a given cutting element, it will continually present a sharp cutting edge to the metal object being cut. Each cutting face of each cutting element can also have one or more surface irregularities to cause the metal chips cut from the casings to break off at short lengths.

    Abstract: The present invention provides a downhole cutting tool for cutting materials at a worksite in a wellbore. The cutting tool includes a cutting end that is adapted to discharge a high pressure fluid therefrom. A power unit in the tool includes a plurality of serially arranged pressure stages, wherein each such stage increases the fluid pressure above its preceding stage until the desired high pressure has been obtained. The high pressure fluid is discharged through the cutting end to effect cutting of a material. A pulsar in the tool is provided to pulse the fluid before it is discharged through the nozzle, which enables the use of lower pressure compared to the pressure required without pulsation of the fluid. A control unit controls the position and orientation of the cutting end relative to the material and may be programmed to cut the material according a predetermined pattern provided to the control unit. An imaging device may be included in the downhole cutting tool to obtain images of the worksite prior to and after the cutting operations.

    Abstract: A tool for cutting or milling casing in a well is disclosed. It includes a plurality of blades extending outwardly to a substantially radial position for cutting the walls of casing strings and removing a predetermined length of the casing strings in a cutting action. The blades have cutting elements positioned on leading faces of the blades to engage the casing strings in a cutting action without tripping or removal from the bore hole. The cutting element has surface irregularities to cause the metal chips cut from the casings to break off at short lengths. The cutting element can also have stress relieving grooves to prevent the propagation of a crack across the face of the element.
