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.

Method of incorporating remote communication with oilfield tubular handling apparatus

Apparatus and corresponding method for remotely communicating with a device in a wellbore, comprising: an oilfield tubular handling apparatus (); partial toroidal coil sections () integrated with the oilfield tubular handling apparatus, wherein the partial toroidal coil sections form a toroidal coil upon a tubular member () with the handling apparatus; and a microcontroller for communicating with the device via at least one of signals transmitted or received through the tubular member using the toroidal coil.

A method of completing a subsea wellbore includes providing one or more conductor anchoring assemblies on an outer surface of a conductor; forming the subsea wellbore; positioning the conductor in the subsea wellbore; and energizing the one or more conductor anchoring assemblies into contact with the subsea wellbore, thereby stabilizing the conductor in the subsea wellbore. In yet another embodiment, the method further includes extending the subsea wellbore; positioning a casing inside the conductor, wherein the casing includes a casing anchoring assembly; and energizing the casing anchoring assembly into contact with the conductor.
