Abstract: A downhole abrading tool has a body with a first end for connection to a drill string, a cutting end, an exterior surface, a drilling fluid passageway, a valve, and a chamber. Upon exposure of the chamber to a wellbore fluid pressure due to excessive wear on the cutting end, the valve opens. The opening of the valve permits drilling fluid to flow from the drilling fluid passageway, through the exterior surface and into the wellbore. The flow of drilling fluid through the exterior surface causes a pressure drop that is detected at the surface by an operator of the downhole abrading tool. The valve movement may also cause the release of taggants, or indicators, into the drilling fluid that may also be detected by the operator, either visually or with the aid of detection equipment.

Abstract translation: 井下研磨工具具有主体，其具有用于连接到钻柱，切割端，外表面，钻井流体通道，阀和腔室的第一端。 当由于切割端上的过度磨损而使室暴露于井筒流体压力时，阀打开。 阀门的开启允许钻井液从钻井液通道流过外表面并进入井眼。 钻井液通过外表面的流动导致由井下研磨工具的操作者在表面检测到的压降。 阀门运动还可能导致标记物或指示器释放到钻井液中，钻井液也可以在视觉上或借助于检测设备被操作者检测到。

Abstract: A lateral exit in a casing is formed by starting with a shaped charge to produce a semi-circular cut of about 180 degrees in the casing. A spreader tool pushes in opposed directions at opposed ends of the cut making some of the casing wall at the cut curl inwardly. A wedge shaped tool is advanced behind the curled metal to force it to collapse on itself to create a long tapered ramp that act as would a whipstock. A one trip operation is contemplated. The drill is then guided by the doubled and tapered casing wall right into the formation without having to mill a window in the casing wall.

Abstract: A connection to a stub downhole is accomplished in a variety of ways. A string has a tapered lower end inserted into the stub and expansion occurs from within the tapered lower end into the stub to leave a connection without reduction of the internal diameter. An overshot fitting can be lowered outside the stub and the stub expanded from within against the overshot. Both options in a single tool can be used to get sealing around the inside and the outside of the stub. An adjustable swage can be used with the overshot configuration where the overshot has an internal groove. The adjustable swage expands from within the stub into the surrounding groove in the overshot.

Abstract: Milling in casing that is over 4½ inches is done with coiled tubing that is anchored against torque reaction. An improved debris catcher is part of the bottom hole assembly to capture cuttings from the milling. A thruster can be used to maintain weight on the mill during the milling. The coiled tubing supports a mud motor to drive the mill. Return fluid is separated from the cuttings and returned to the surface.

Abstract: A downhole abrading tool having a body with a first end for connection to a drill string, a cutting end, a drilling fluid passageway, a restrictor disposed within drilling fluid passageway, and an indicator chamber is disclosed. Upon exposure of the indicator chamber to a well environment due to excessive wear on the cutting end, the restrictor is actuated. Actuation of the restrictor restricts the flow of drilling fluid from the drilling fluid passageway into the well environment. The restriction of flow of drilling fluid from the drilling fluid passageway causes a pressure increase in the drilling fluid flowing through the well that can detected by an operator of the downhole abrading tool. The pressure increase provides an indication to the operator of excessive wear on the cutting end of the downhole abrading tool so that the downhole abrading tool can be removed from the well and replaced.

Abstract: A downhole abrading tools has a body with a first end for connection with a rotating component of a drill string and a cutting end for rotation in unison with the body. The downhole abrading tool also includes a passage through the tool for circulating a drilling fluid. Disposed within the drilling fluid passageway is a taggant injection assembly having one or more taggants disposed therein that facilitates injection of taggants into the drilling fluid upon the cutting end experience excessive wear. The taggants are then transported to the surface location along with the drilling fluid for detection by the operator of the downhole abrading tool.

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.
