Abstract: A downhole equalization assembly permits selective and remote opening of at least one downhole port or pathway to allow communication of pressure and/or fluid flow from inside a pressure containing system (such as, for example, a tubular pipe or other pressure containment system) to the outside of the containment system, or vice versa. A control device generating a magnetic field is inserted into a well and conveyed to a downhole equalization assembly. When the control device passes through an equalization assembly, an electrical current is generated that triggers an electronic counter. When a predetermined counter number is reached, a sliding sleeve is shifted, thereby exposing ports and/or pathways extending between the inside and outside of the equalization assembly. No physical contact or mechanical interference is required between the control device and any other components in order to actuate the equalization assembly.

Abstract: A system and method for selectively stimulating a plurality of producing zones in a wellbore in oil and gas wells. The system includes a plurality of modules connected in a string that may be selectively actuated to stimulate a producing zone. Each module may be adapted to engage a tubing run ball seat. After installation of the string within the wellbore, a ball seat may be run into the well and positioned to selectively engage a desired module. The ball seat may be used to open a sleeve of the module permitting the stimulation of the producing zone. After stimulation of the producing zone, the ball seat may be removed from the wellbore rather than needing to drill out the ball seat. The sleeve may include a profile adapted to engage a shifting tool permitting the selective closure of the sleeve after stimulation of the producing zone.

Abstract: A method and apparatus for use in a subterranean well is described. The apparatus typically includes a mandrel and a packing element. The mandrel may have an outer surface and a non-circular cross-section and the packing element may be arranged about the mandrel, the packing element having a non-circular inner surface matching the mandrel outer surface such that concentric rotation between the mandrel and the packing element is precluded. The apparatus may include slips having cavities to facilitate removal of the apparatus. The apparatus also may include a valve for controlling upward fluid flow through a hollow mandrel. The valve may include a flapper having at least one tab to engage at least one recession in the mandrel such that rotation between the mandrel and the valve is precluded when the valve is in a closed position. The apparatus may further include a central member which is releaseably attached to the mandrel by a release mechanism.

Abstract: This invention is drawn to a weighted fishing hook assembly. The hook assembly includes a substantially flat deflector, with a slightly arcuate cross section. Slightly rearward of center a hook is attached which depends downwardly from the deflector. Directly beneath the hook attachment point is a weight. A lure is attached to the hook and the hook assembly is ready for use with the enclosed method.

Abstract: A deer lure and method is presented whereby urine from a domestic goat is utilized. An absorbent cotton is saturated with undiluted urine and is suspended in a substantially triangular type area configuration whereby the sides of the triangle are each about twenty yards in length with absorbers at the points of the triangle. Additional urine is placed on the ground in the center of the triangle. Both buck and doe are attracted as the scent producing urine as it permeates the atmosphere. A method of collecting urine from domestic goats and apparatus is also provided utilizing a mesh covered pan.
