Abstract: A polyamide suture includes an elongate core formed of multiple twisted and heat set filaments formed of a first polyamide material and a sheath formed of a second polyamide material surrounding the core along its length, the second polyamide material having dispersed therein non-absorbable radiopaque nanoparticles comprising 15-25% by weight of the second polyamide material. The melting point of the first polyamide material is at least 30° C. greater than the melting point of the second polyamide material. The core may also include or be formed of previously extruded bundles of first polyamide filaments overcoated with a second polyamide sheath. The suture is made by coextruding the core and a molten organic material formed of the second polyamide material and dispersed radiopaque nanoparticles. Desirably, the first polyamide material is Polyamide 66 and the second polyamide material is Polyamide 6.

Abstract: A valve for use in fracing through cement casing in a well allows for flow of cement down the well during the cementing process and in the open position allows for fracing fluid to be directed through the cement casing for fracturing the formation adjacent the valve. The valve is constructed so as to reduce the likelihood of the valve to jam as a result of cement or other foreign material.

Abstract: Apparatuses and methods used for actuating downhole tools in which a ball is dropped from a surface of a wellbore until it contacts a ball seat of a downhole tool. The ball seat moves axially downward within the downhole tool and an expandable ball seating surface of the ball seat radially expands to pass the ball. The ball seat then moves axially upward within the downhole tool.

Abstract: A valve includes: a housing; a mandrel disposed in the housing; a rupture disk disposed in a passageway of the mandrel; a sliding sleeve disposed between the housing and the mandrel; and a ball seat disposed in the mandrel. A method for actuating a valve includes: flowing a fluid through the valve; dropping a ball; seating the ball in the ball seat and blocking fluid flow through the mandrel; flowing fluid through the passageway to the sliding sleeve; moving the sliding sleeve axially within the valve; and exiting fluid through the openings of the housing and mandrel. A valve includes: a housing having an opening; a mandrel disposed in the housing; a sliding sleeve disposed between the housing and the mandrel; and a ball seat disposed in the mandrel blocking fluid communication between the mandrel and the passageway.

In one aspect, a method of selectively isolating a zone in a wellbore is provided. The method includes the step of positioning a downhole tool in the wellbore. The downhole tool includes a bore with a first flapper member and a second flapper member disposed therein, whereby each flapper member is initially in an open position. The method also includes the step of moving the first flapper member to a closed position by rotating the first flapper member in one direction. Further, the method includes the step of moving the second flapper member to a closed position by rotating the second flapper member in an opposite direction, whereby each flapper member is movable between the open position and the closed position multiple times. In another aspect, an apparatus for isolating a zone in a wellbore is provided.
