Abstract: A method and apparatus that provides a quick connection for a hydraulic fracturing plug to a drill string mandrel. In an embodiment, the hydraulic fracturing plug includes one or more pins for connecting to one or more corresponding connection points on the drill string mandrel. The connection points may include a first section and a second section, where the second section may include an end point for receiving a pin on the hydraulic fracturing plug. The connection between the hydraulic fracturing plug and the drill string mandrel may also include a master pin.

Abstract: An improved plug with shuttle valve is disclosed. The improved plug has a bore in which a shuttle valve travels between stops in the bore. The traveling shuttle valve serves to reduce wellbore pressure across at least portions of the plug, thereby at least reducing the possibility of damage resulting from undue wellbore pressure and leak spots.

Abstract: Plugs for use in hydrocarbon recovery operations having lower and upper anchor slip assemblies with individual anchors, upper and lower elements, a shoe and tubular mandrel.

Abstract: A method of production of a frac plug is disclosed comprising providing a blank defining an interior of the frac plug, placing a glass material around the blank such that a fiber reinforcement within the glass material is off axis to a longitudinal axis of the frac plug and wherein the placing forms a glass material blank, removing the blank from the glass material blank and performing at least one mechanical processing of an exterior of the glass material blank.

Abstract: A method and apparatus that provides a quick connection hydraulic fracturing plug that allows the hydraulic fracturing plug to connect to a mandrel of a drill string with installation of a single shear pin to establish a connection.

Abstract: A multi-function mandrel system that is used for setting downhole devices and for capturing restriction elements while downhole as opposed to having to flow back restricted elements to surface.

Abstract: An arrangement for visually identifying cuttings from different stages in a well is provided. In aspects of the disclosure, plugs may have different markers according to their respective position in a well, thereby allowing operators to visually identify locations in a well.

Abstract: This cord tensioning device allows for the easy attachment of an item needing to be secured, such as a tent or tarp to various types of anchor points without the ability to tie knots. The device includes: a body portion having a major surface said body portion having a distal section and a proximal section; at least two openings dimensioned to receive a cord, one of said openings located in the proximity the proximal section and the other of said openings located in proximity of the distal section. The proximal section further includes a head section and two arm sections and a slot between each of the head and arm sections. The slots are sized to be smaller than the interior shoulder portion and will frictionally hold a cord within the slot.

Abstract: The present invention relates to electronic locks and electronic locking systems, to electronic locking systems which use remotely encoded keycards and, in particular, to an electronic locking system which utilizes public key cryptography.
