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: 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: 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: 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.
