Abstract: A substrate for emitting a volatile material, the substrate comprising a first woven layer, a second woven layer, and a third layer. The first woven layer has a first weave pattern. The second woven layer has a second weave pattern that is different than the first weave pattern. The third layer is disposed between the first woven layer and the second woven layer. Further, the substrate is configured to provide a steady state weight loss of the volatile material between about 1 mg/day and about 10 mg/day over a time of at least 30 days.

Abstract: A multi-layer article including a first non-active state and a second active state, the multi-layer article comprising an outer layer having a first side and a second side, an inner layer adjacent to at least a portion of the outer layer and including a volatile material, and an upper layer including a first side and a second side, the first side of the upper layer being adjacent to at least a portion of the inner layer. The multi-layer article is folded upon itself in the first non-active state so that at least a first portion of the second side of the upper layer is disposed on a top of a second portion of the second side of the upper layer, and the first portion and the second portion of the upper layer are heat sealed in the non-active state.

Abstract: A system for consistently emitting a volatile material, the system including a dispenser having at least one aperture, a substrate adapted to fit within the dispenser, and a volatile material. The substrate includes a first woven layer having a first pore size, a second woven layer having a second pore size, and a third, non-woven layer that extends between the first woven layer and the second woven layer. Further, the system has a steady state weight loss of the volatile material over a time greater than 30 days.

Abstract: A downhole tool and method of operation thereof is provided. The downhole tool may be configured to permit fluid communication between a combined flowbore of the casing string and the downhole tool and the subterranean formation or wellbore, or both, after a pressure test has been completed, a second threshold pressure is reached or applied, and a third threshold pressure has been applied to the downhole tool.

Abstract: A downhole shifting mechanism having an inner tubular member, an outer tubular member, a piston, a first set of teeth, a sliding block, a body lock ring, a first flow path, and a second flow path is described herein. A downhole assembly can include the downhole shifting mechanism with a downhole tool connected to a second end of the downhole shifting mechanism. Also described is a method for shifting a downhole tool disposed within a wellbore.
