| A method of fracturing a wellbore formation that includes positioning an end of a coiled tubing string adjacent a first location within a wellbore, pumping fluid down the wellbore to fracture the formation, and monitoring a pressure within the wellbore during the procedure with at least one sensor connected to a communication line. The fracturing procedure may be a re-fracturing of the wellbore. The method may include actuating a single isolation element or two isolation elements to isolate a portion of the wellbore to be fractured. The method may include modifying the fracturing procedure in real time based on data from monitoring the pressure during the procedure. A system for fracturing a wellbore includes coiled tubing, a communication line within the coiled tubing, and at least one pressure sensor connected to the communication line. Pressure sensors may be connected to both the exterior and interior of the coiled tubing. | ||||||

| 196 | METHOD OF INCORPORATING REMOTE COMMUNICATION WITH OILFIELD TUBULAR HANDLING APPARATUS | US15257384 | 2016-09-06 | US20160369573A1 | 2016-12-22 | Sorin Gabriel TEODORESCU; Hallvard Svadberg HATLOY; Tarald GUDMESTAD; Lev RING |
| 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. | ||||||
