Abstract: A rupture apparatus (50) often deployed within a wall of a casing string (53) of an oil and gas well, comprising a housing (51) defining a housing bore (54) with a bore inlet and a bore outlet; a carriage carrying a rupturable component (12) the carriage being moveable in the housing bore between a rupturable position, an open and a closed position. Thus the bore can be opened or closed or closed subject to rupture of the rupturable component (12). Moreover, after rupture the bore can still be closed. Wireless signals are normally used to for control, especially electromagnetic or acoustic signals. A pressure balancing port (6) may be defined in a wall of the housing allowing fluid communication between at least a portion of the housing bore, and an outside of the housing which can pressure-balance the carriage such that it remains stationary unless actuated.

Abstract: A well (10) in a geological structure (11), the well (10) comprising: a first casing string (12a) and a second casing string (12b) inside the first casing string (12a) and defining a first inter-casing annulus (14a) therebetween. A wirelessly controllable valve (16a), in the second casing string (12b) provides fluid communication between the first inter-casing annulus (14a) and a second casing bore (14b). The first or second casing string are less than 250 meters longer in length than the second or first casing string respectively and may be the same length. The distal ends of the first and second casing strings may be in a substantially impermeable formation (11). A number of benefits can be realised from such an arrangement. For example, in the event of a “blow-out”, kill fluid may be introduced into the well bore without the need to drill a relief well.

Abstract: A method of pressure testing a casing system (12) comprising deploying an apparatus (110) with a container (68) formed from drill pipe or production tubing, on a string of drill pipe or production tubing into a well, such that a port (61) thereof is provided in an isolated section of the well. The isolated section of the well has a higher pressure than the pressure of a gas sealed in the container (68). The port (61) is opened and pressure in the isolated section is monitored to assess its integrity. Communication with the apparatus is achieved by wireless means sending pressure data, control signals for controlling the port and/or other data or commands.

Abstract: A method to manipulate a well, comprising running an apparatus (60a) having a container (68a) with a volume of gas at a higher pressure than a surrounding portion of the well. The well is isolated, and a wireless control signal, such as an electromagnetic or acoustic signal, is sent to operate a valve assembly (62a) to selectively allow or resist fluid exit from a portion of the container (68a), via a port (61a). Some of the pressurised gas may itself be expelled in to the surrounding portion of the well, or it may be used to drive a fluid out of the container, such as an acid.

Abstract: A method to manipulate a well comprising providing an apparatus (60) in a well (14) below a packer (22) or other annular sealing device, the apparatus comprising a container (68) having a volume of gas which is sealed at the surface and nm into the well, such that the pressure in the container (68) is at a lower pressure than the surrounding well. When the apparatus is below the packer, a wireless control signal, is sent to operate a valve assembly (62) to selectively allow fluid to enter the container whereby at least 50 litres of fluid is drawn into the container. In this way, the apparatus can be used independent of perforating guns, to clear perforations or other areas in the well or may be used for a variety of tests such as an interval test, drawdown test or a connectivity test such as a pulse or interference test.

Abstract: A well (10) in a geological structure, the well (10) comprising a first casing string (12a) with a second casing string (12b) partially inside, and a third casing string (13c) partially inside the second casing string (12b). A first inter-casing annulus (14a) is defined between the first (12a) and second casing strings (12b), and a second inter-casing annulus (14b) is defined between the second (12b) and third casing strings (12c). A primary fluid flow control device (16a), such as a wirelessly controllable valve, on the second casing provides (12b) fluid communication between the first inter-casing annulus (14a) and the second inter-casing annulus (14b); and a secondary fluid flow control device (16b), such as a second wirelessly controllable valve, on the third casing string (12c) provides fluid communication between the second inter-casing annulus (14b) and a bore of the third casing (14c). In the event of a “blow-out”, a kill fluid can then be introduced into an annulus and the fluid flow control devices used to allow the kill fluid to cascade down the well to control it. Accordingly, the time taken to drill a relief well may be mitigated or obviated which can reduce the time and cost to control the well and can mitigate environmental impact of hydrocarbon loss caused by the blow-out.
