Abstract: A tool, known as FM/WL Tool, utilized with a wireline adaptor kit would be secured to the lower end of a wireline setting tool. The adaptor kit would release from the tool when sufficient setting force is applied, and is retrieved with the wireline setting tool. The wireline setting tool provides for a telescoping action and sufficient force in order to push the outer parts down from the top as the inner mandrel of the tool and the stinger, top sub and bottom sub are pulled upward. The upward pull is transferred to a sleeve by a plurality of lugs on bottom sub assembly. This action causes the packer tool to set by compressing rubber elements and holding the elements compressed by a first upper set of slips and a second lower set of slips wedged between the casing and the upper cone and the lower cone. During the setting action, the pickup sleeve and parts attached will move down until the top slips are wedged against the top cone.

Abstract: An outboard guard assembly includes a support tube, barrier panel attached to the support tube, and reinforcing brace attached to the barrier panel. The outboard guard assembly is mounted on each of a pair of outboard crop divider structures of an existing multi-row crop gathering header used to harvest crops planted in rows, such as corn. When installed on the outboard crop divider structures at either end of the multi-row corn header, the outboard guard assembly improves the effectiveness of the multi-row crop gathering header and reduces yield loss caused by variation in row spacing and bent and tangled corn stalks.

This mill is can rapidly penetrated casings without requiring excessive torque. The milling can be accomplished with a single trip.

Abstract: A method for improving the productivity of a well by separating and disposing of at least a portion of the water which is produced from a subterranean producing formation. The water is allowed to separate from the produced fluids under the influence of gravity while in the wellbore. The separated water is then disposed without removing it from the wellbore by flowing it into a subterranean disposal formation which has a pressure less than that of said producing formation. Preferably, the well is completed with an inclined wellbore which significantly aids in the gravity separation of the water from the produced fluids (e.g. hydrocarbons).

Abstract: A blade assembly for a brush cutting machine. The blade assembly comprises two blades, each blade having a two sided cutting edge on both a first and second ends. The four sided cutting edge blades are rotatable from the first end to the second end and invertible from the upper surface to the lower surface to take advantage of all four cutting edges on each blade. A first blade is attached to the bottom surface of a first end of the crossbar. A second blade is attached to the bottom surface of a second end of the crossbar. The blades are attached to the bottom surface of the crossbar with counter-bored holes in the blades that correspond to counter-bored holes in the crossbar. Counter-bored holes in the bottom surface of the blades recess the head of the attaching bolt so that the top of the head of the attaching bolt is flush with the bottom surface of the blades.

Abstract: A rotary cone drill bit for forming a borehole having a one-piece bit body with a lower portion having a convex exterior surface and an upper portion adapted for connection to a drill string. The drill bit will generally rotate around a central axis of the bit body. A number of support arms are preferably attached to pockets formed in the bit body and depend therefrom. Each support arm has an inside surface with a spindle connected thereto and an outer surface. Each spindle projects generally downwardly and inwardly with respect to the longitudinal axis of the associated support arm and the central axis of the bit body. A number of cone cutter assemblies equal to the number of support arms are mounted respectively on each of the spindles. The spacing between each of the support arms along with their respective length and width dimensions are selected to enhance fluid flow between the cutter cone assemblies mounted on the respective support arms and the lower portion of the bit body.

Abstract: A method of cleaning an oil or gas well includes mixing a caustic with a saline solution to precipitate hydroxide species from the saline solution and form a milky suspension. The suspension is contacted with contaminants in a well bore to entrap the contaminants. A polymeric flocculant is then mixed with the suspension in the well bore to aggregate the hydroxide species and the entrapped contaminants into flocs. The flocs are extremely strong and can withstand the highly turbulent flow existing in the well bore and can be readily flushed out of the well bore.

Abstract: A wear-resistant sheath for a cylindrical drill string component, includes a cylindrical fiber-reinforced matrix snugly embracing the drill string component. Embedded in the sheath is a spaced array of hard substantially cylindrical pins, each of which has a body having an opposed pair of ends. The pins are disposed substantially radially of the sheath, with one end of each pin disposed substantially at the outer surface of the sheath, the other end being preferably disposed in contact with the component and embedded therein to lock the sheath to the component.

Abstract: A rotary mower includes a housing which contacts a ground surface to be mowed, a blade mounted for rotation in the housing a motor mounted to the housing for driving the blade, and an actuator mechanism for disabling rotation of the blade when the housing is displaced a predetermined distance from the ground surface.

Abstract: A method for fracturing and propping a thick and/or non-homogeneous fracture interval of a subterranean formation which is traversed by a wellbore. A workstring is lowered into the wellbore and a fracturing fluid is flowed into one end of the fracture interval annulus (i.e. that portion of the well annulus which lies adjacent the fracture interval) to initiate a fracture. The flow of fracturing fluid is ceased and a slurry containing proppants is flowed into said one end of the fracture interval annulus. During flow of fracturing fluid and slurry into said one end of the annulus, both are delivered through alternate flowpaths to different levels within said fracture interval. Alternate slugs of fracturing fluid and slurry is continued through the same end of the annulus until all of the levels or zones within the fracture interval have been fractured and propped and in some instances, also gravel-packed.

Abstract: A conventional header of a combine is modified by the addition of a second sickle knife positioned rearwardly of the pan of the header. The second sickle knife is mounted on a bar which is connected to a pair of arms extending under the pan to a forward end pivotally mounted just behind the conventional sickle knife of the header. The arms and the second sickle knife can thus pivot upwardly and downwardly and are mounted on suspension springs carried on the frame of the header. A simple drive from the conventional shaft of the header is connected through a belt to a drive wobble box carried on the second sickle knife at a position partway along its length.

Abstract: The present invention is a method and apparatus for inserting electric wireline tools into a wellbore using an apparatus comprising pipe assembled from sections and coiled tubing having a coaxially inserted wireline. The method includes the steps of attaching a first part of a submersible electrical connector to one end of the coiled tubing and to the wireline inside the coiled tubing. A second part of the submersible connector is attached to one end of the wireline tools. A first part of a selectively operable latching mechanism is attached to the same end of the wireline tools. A second part of the latching mechanism forms part of a latching sub which is attached to one end of the pipe. The tools are attached to the pipe by engaging the first and second parts of the latching mechanism, and the tools are inserted into the wellbore to a predetermined depth by assembling the sections of the pipe. The coiled tubing is then inserted into the interior of the pipe until the submersible connector is engaged.
