摘要： A sliding sleeve for frac operations or the like has a housing, a sleeve, and a shock absorber. The sleeve is movable within the housing's internal passage relative to flow ports. The shock absorber, which can have a cylindrical body, positions partially in the sleeve's internal passage and has a distal end that extends beyond the sleeve. A lip on the sleeve's end is engageable with the internal shoulder. When a ball is dropped on the sleeve's ball seat and pumped fluid forces the sleeve to an open position, the shock absorber absorbs the movement of the sleeve. To absorber the movement, the shock absorber breaks one or more shear pin connections with the sleeve, interposes its lip between the sleeve's distal end and the internal shoulder, and fractures at least a portion of its distal end from the impact with the sleeve.

摘要： Sliding sleeve mechanisms including protective sheaths for debris protection are disclosed. Protective sheaths can be formed from materials such as composites, metal, foil, rubber, plastic, glass, ceramic, wire mesh, tape, etc. The protective sheaths can be substantially cylindrical shells (having one or more pieces), plugs in the flow ports, and/or tape or wire wrappings. The protective sheaths can be retained by recesses in the sliding sleeve or mechanical fasteners such as screws, pins, rivets, snap rings, bands, and buckles. The protective sheath can be outside or inside the sliding sleeve. The protective sheath can protect the sliding sleeve from debris by retaining grease that has been packed into the sliding sleeve for that purpose or positively preventing entry of debris into the sliding sleeve. The protective sheath can be cleared by permitting fluid flow through the sliding sleeve, which can act to destroy and/or wash away the protective sheath.

摘要： The present invention generally relates to controlling the flow of fluids in a wellbore. In one aspect, a valve for selectively closing a flow path through a wellbore in a first direction is provided. The valve includes a body and a piston surface formable across the flow path in the first direction. The piston surface is formed at an end of a shiftable member annularly disposed in the body. The valve further includes a flapper member, the flapper member closable to seal the flow path when the shiftable member moves from a first position to a second position due to fluid flow acting on the piston surface. In another aspect, a valve for selectively closing a flow path through a wellbore in a single direction is provided. In yet another aspect, a method for selectively closing a flow path through a wellbore in a first direction is provided.

摘要： A fluid conditioning system designed to be installed between the well perforation and the intake of a pump used to effect artificial lift is used to filter and chemically treat production fluids. The fluid conditioning system is an apparatus that provides scale inhibitors and/or other chemical treatments into the production stream. In some embodiments, the fluid conditioning system may be a part of the production stream filter wherein the filtering material is comprised of a porous medium that contains and supports the treatment chemical. In other embodiments, the chemical treatment may be accomplished by the gradual dissolution of a solid phase chemical. The treating chemical may be recharged or replenished by various downhole reservoirs or feeding means. In yet other embodiments, the treating chemical may be replenished from the surface by means of a capillary tube. In certain other embodiments, the apparatus may be retrievable from the surface thereby permitting recharge or replenishment of the chemical in the apparatus on an as-needed basis. The filtration apparatus may incorporate a bypass valve that allows fluid to by-pass the filter as sand or other particulate matter fills up or blocks the filter.

摘要： A method of producing hydrocarbon includes introducing the hydrocarbons into a tubular for transport to a surface and introducing a gas into the tubular, wherein the gas is introduced as miniature bubbles for mixing with the hydrocarbon. The method also includes mixing the bubbles with the hydrocarbons, thereby reducing a hydrostatic pressure in the tubular and flowing the hydrocarbons toward the surface. In one embodiment, the gas is introduced at one or more gas lift entry points along the tubular.
