Abstract: Downhole tools with a topographical pattern, and anti-balling material over the topographical pattern. The topographical pattern may be defined by at least one of a plurality of recesses extending into a surface of a body of the tool and a plurality of protrusions protruding from the surface. Downhole tools include an insert disposed within a recess in a body, and the insert comprises an anti-balling material having a composition selected to reduce accumulation of formation cuttings on the tools when the tools are used to form or service a wellbore. Downhole tools include anti-balling material disposed over a porous mass provided over the surfaces of the tools. Methods of forming downhole tools include providing anti-balling material over features on and/or in a surface of a body of a tool. Methods of repairing downhole tools include removing an insert therefrom and disposing a replacement insert therein.

Abstract: Earth-boring tools may include a body and a passively adjustable, aggressiveness-modifying member secured to the body. The passively adjustable, aggressiveness-modifying member may be movable between a first position in which the earth-boring tool exhibits a first aggressiveness and a second position in which the earth-boring tool exhibits a second, different aggressiveness responsive to forces acting on the passively adjustable, aggressiveness-modifying member.

Abstract: Cutting elements, earth-boring drill bits having such cutting elements and related methods are described herein. In some embodiments, a cutting element for an earth-boring tool may include a diamond table having an indentation in a cutting face thereof and a shaped feature in a substrate at the interface between the diamond table and the substrate, the shaped feature corresponding to the indentation in the cutting face of the diamond table. In further embodiments, a cutting element for an earth-boring tool may include a sacrificial structure positioned within an indentation in a diamond table. In additional embodiments, a method of forming a cutting element may include positioning a sacrificial structure in a mold, positioning a powdered precursor material over the sacrificial structure, and pressing and sintering the powdered precursor material to form a diamond table having an indentation in a cutting face formed by the sacrificial structure.

Abstract: A sealing element is flanked by wedge-shaped extrusion ring assemblies. The rings climb a ramp on an adjacent pedestal ring on the way out to the borehole wall. Depending on the dimension of the gap to be spanned the extrusion rings slide part way up the pedestal ring ramp or to the top of the pedestal ring. An anchor ring is initially forced up an opposite ramp of the pedestal ring. If the sealing gap is short the anchor ring touches the borehole wall to act as an anchor for the plug while remaining spaced apart from the extrusion ring assembly. For larger gaps the anchor ring moves out far enough to the borehole wall and in contact with the extrusion ring located on top of the pedestal so that reaction forces are directed to keep the anchor ring wedged in position for support of the extrusion ring assembly.

Abstract: A method of forming a casing bit includes positioning a cutting element adjacent an outer surface of a casing bit body. The cutting element has a superhard material and a bonding material that is used to bond the cutting element to a body of the casing bit. The bonding material may be a weldable or brazable metal alloy, and a welding process or a brazing process, respectively, may be used to bond the cutting elements to body of the casing bit. Casing bits fabricated using such methods may exhibit reduced bond strength between the cutting elements and the casing bit body.

Abstract: An ECM method involves the use of a thin hollow electrode assembly that carries the electrolyte within and that is advanced relatively to the workpiece. The small profile of the electrode results in a minimal removal of metal in forming the desired rotor or stator shape. The electrode profile allows significant power consumption reduction or increased machining speed for a given rate of power input. The electrode can be a unitary ring shape or can be made of segments that are placed adjacent each other so that a continuous shape is cut. Not all the lobes of the stator or rotor have to be cut in the same pass. Electrode segments can be used to sequentially provide the desired lobe count in separate passes. The lobe shapes in the electrode can be slanted to get the desired rotor or stator pitch or they can be aligned with the workpiece axis.

Abstract: A fishing tool for a fishing arrangement to remove a stuck fish or object from a wellbore. The fishing tool includes an overshot housing which defines an interior chamber. An inflatable bladder element resides within the interior chamber and is inflatable radially inwardly to capture a portion of the stuck fish. The fish is removed as the fishing arrangement is pulled out of the wellbore.
