Abstract: Signal communications at a drilling system generally includes communicating upwards or downwards from the rig floor. For example, signal communications upwards may comprise the control of a cementing head operation (e.g., actuating cementing head). Signal communications downwards may comprise the activation of tools and their confirmation (e.g., hole opening tools, liner hangers, and packers). Actuation may be performed via umbilicals, for example, via pressure spikes or the dropping of balls, darts, or radio-frequency identification (RFID) tags. However, issues may arise wherein, for example, a ball may not properly land to close a circulation valve. As another example, a cementing head could be over 100 feet above the rig floor, which may make it difficult for signal communications via an umbilical. Accordingly, what is needed are techniques and apparatus for activation of tools and their confirmation by a remote communication system.

Abstract: An apparatus for setting a liner (1) in a casing (2) comprises a liner hanger (LH) and a running tool (100). The running tool (100) is provided with a valve seat (5) obstruction of which, in use, allows fluid pressure to be developed to set the liner hanger (LH) in the well casing (2). After the liner hanger (LH) has been set, the application of further pressure will displace the valve seat (5) to release (or at least enable) the running tool (100) to be released and to allow fluid flow through the running tool (100).

Abstract: A packer, and operation of the same, which forms elastomeric seals and non- elastomeric seals. The packer may be constructed from a non-elastomeric tubular core having a frustoconical shaped inner diameter. The outer diameter of the core may be substantially smooth and carry one or more elastomeric sealing elements. The packer is set by causing the diametrical expansion of the tubular core. The construction of the tubular core is preferably such that its diametrical expansion causes the formation of radial raised portions (upsets) on the outer surface. These raised portions form the non-elastomeric seals and also prevent extrusion of the elastomeric sealing elements.

Abstract: Disclosed herein is a temporary well isolation device, which is sealingly disposable in downhole tubing, and which has a housing with an axial passage . The temporary well isolation device also has frangible barrier element withi n the housing, where the frangible barrier element is sealingly engaged in the passage blocking fluid flow through the passage. The frangible barrier element bears a load from fluid pressure. The temporary well isolation device also has a disengagable constraint in contact with a frangible barrier element so as to redirect the load on the frangible barrier element from a first component of the load to a second component of the load, thereby preventing rupture of the frangible barrier element. Also disclosed herein is a method for disintegrating a frangible barrier element disposed in a passage of a temporary well isolation device.

Abstract: A connector arrangement used for connecting and locking tubular members. The connector consists of two tubular members and a coupling member. The tubular members are threaded together to create a threaded connection. The locking arrangement is provided by a pathway formed on the tubular member whereby a locking member can be inserted in to the pathway to lock the threaded connection. The locking arrangement is also provided by a plurality of castellation members disposed on each tubular member. The connector also has a separate coupling member which has opposite right-hand and left-hand threaded ends to threadedly mate with the threads of the two tubular members.

Abstract: A temporary well isolation device has an axial passage 104 in fluid communication above and below the device. A frangible barrier 108 seals the passage to block fluid flow through the passage and thereby bears a load from fluid pressure. A structural element acts on the frangible barrier to selectively redirect the load on the frangible barrier element, thereby preventing or facilitating rupture. The structural element may be a disengagable constraint formed by a movable sleeve 112 that forms a compression-loaded structure when in contact with the frangible barrier. Upon disengagement, the frangible barrier bears a primarily tensile load that facilitates its rupture. The frangible barrier may be hemispherical.
