摘要： 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.

摘要： 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.

摘要： 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.
