Abstract: A plunger for an artificial lift system and embodiment of the plunger includes a solid body adapted to travel within a production string positioned in a wellbore. At least one sealing ring connected about the body. The at least one sealing ring having an inner surface, an outer surface, a width and a thickness. The width is sufficient such that when the body is disposed in the production string the outer surface contacts and substantially forms a seal between the body and an inner wall of the production string. The at least one sealing ring having an outside diameter greater than the inner diameter of the production tubing within which the body is adapted to travel such that when the body is disposed within the production string an interference fit causes the sealing rings to roll-form into a constricted shape and diameter that exerts the sealing contact with the production string.

Abstract: A well optimizing system and method for lifting fluid that accumulates and retards production in a well. The system includes a plunger having a piston and a detachable plugh. The piston has a sealing section and a retrieval end and defines a passage through the length thereof. One or more pads are radially extendable from the sealing section. The detachable plug is positional in the retrieval end in a position to substantially block the flow of fluid through the passage from below the plunger. The system may further include a production control system.

Abstract: A method and system for controlling a producing cycle in a well, during the production cycle, for optimizing production from the well including disrupting fluid in a wellbore with a pulse generator to create a pressure pulse transmitted through the fluid in the wellbore, detecting the pressure pulse created and the pressure pulse reflected from objects located within the wellbore, wherein the objects may include a liquid/gas interface and a producing apparatus such as a plunger, converting the detection of the pressure pulse and the reflected pressure pulses to a signal, computing the signals to determine the well status and controlling production of the fluid from the wellbore based on the well status.
