  • Patent number: 11891879
    Abstract: A downhole valve, such as a safety valve or sub-sea safety valve (SSSV). The downhole valve comprising: a housing; a flow path between a valve inlet and a valve outlet; a valve mechanism; and a piston member; wherein the valve mechanism is operable by actuation of the piston member to selectively open and close the flow path between the valve inlet and valve outlet; and the piston member is actuatable by a pressure differential between an annulus pressure at the valve and a pressure at the valve outlet and/or in a portion of the flow path closest to the valve outlet. The valve can comprise an opening for receiving the annular pressure that is isolated from the valve inlet and valve outlet. The downhole valve can be configured such that it prevents operation of the valve mechanism to open and/or close the flow path by a pressure differential between the valve inlet and valve outlet.

  • Patent number: 11773690
    Abstract: A technique facilitates operation of a valve system a having combined valve such as a combined formation isolation valve and a circulating valve. In well operations, the valve system is deployed downhole into a wellbore on a tubing string. The formation isolation valve and the circulating valve are operable independently via inputs, e.g. hydraulic inputs provided through less than three hydraulic control lines. The formation isolation valve and the circulating valve may be coupled by a mechanical linkage, which enables operation of the two valves via the hydraulic control lines. In some embodiments, the formation isolation valve and the circulating valve may be operated via an integrated shifting tool.

  • Patent number: 10184317
    Abstract: A check valve has a valve member flexibly attached to a seat with resilient members that fold in response to flow above a predetermined value to shut the valve. The flexibly extending members store potential energy that is released to separate the valve member from the seat when the pressure applied against the seated valve member declines to the point that the potential energy stored in the flexible members is able to move the valve member off the seat. The valve assembly including the valve member, the seat and the flexible members can be a common material, or can be all one or more nonmetallic materials or involve composites or other easily drilled materials that are compatible with the operating conditions of pressure differential, temperature and composition of the well fluid. The check valve assembly can be pushed with pressure when closed to operate a subterranean tool.

  • Patent number: 10082012
    Abstract: A re-fracturing method involves placement and centralization of a liner string that has shaped charges at predetermined locations that are externally isolated with packers. The shaped charges can be set off in a desired order and re-fracturing can then take place in new locations. In a bottom up order for perforating sequentially larger balls can be landed on seats and developed pressure or component movement generated by applying pressure can be used to set a shaped charge and isolate portions of the borehole below. The balls and even the seats can be later milled out or just allowed to disintegrate or dissolve with well fluids that are present or later added to clear the liner for subsequent production. Alternatively, the liner could be removed by release of the packers before production or injection begins.

  • Patent number: 10060210
    Abstract: A downhole tool includes a housing and a mandrel glidingly arranged within the housing, wherein the mandrel is formed as a piston. The flange is acting on a spring arranged around the mandrel. In a first position of the mandrel, a fluid flow can run 100% through the tool via a first nozzle at a first end of the housing, the inside of the mandrel and a second nozzle at a second end of the housing. At a predetermined flow rate and with the help of a passage arranged in the housing wall and connecting the first side of the tool with the space or ring room on the non-spring side of the mandrel and a side port in the mandrel on its spring side, the mandrel will be moved towards the second nozzle due to sufficient force acting on a flange of the mandrel thus overcoming the spring resistance.

    Abstract: A drill stem test string may include a tubular body having an axial bore formed at least partially therethrough. An axial flow valve may be coupled to the first tubular body and allow fluid to flow axially through the first tubular body when in an open state and prevent fluid from flowing axially through the first tubular body when in a closed state. A radial flow valve may be coupled to the first tubular body and allow fluid to flow radially through the first tubular body when in an open state and prevent fluid from flowing radially through the first tubular body when in a closed state. A seal assembly may be coupled to an outer surface of the first tubular body and positioned between a lower end of the first tubular member and the first radial flow valve.

  • Patent number: 9810343
    Abstract: The annular space surrounding a flow tube in a subsurface safety valve is sealingly isolated at opposed ends of the flow tube and pressure compensated to the tubing pressure. The subsurface safety valve is inserted and aligned in an outer housing so that hydraulic operating connections are sealingly aligned with opposite hand split ring seals that are properly compressed when the safety valve is secured in its surrounding housing. The assembly is then able to meet high pressure, heavy debris, and marine environment service requirements for subsea conditions with minimal reconfiguration for what would otherwise serve as a borehole subsurface safety valve.
