Abstract: A method of performing a coiled tubing application using feedback includes conveying a coiled tubing string along a borehole and obtaining vibration measurement data based on vibrations within the coiled tubing string. The method further includes providing, during the coiled tubing application, feedback based on the vibration measurement data. The method further includes using a mechanical controller to adjust a variable element of the coiled tubing application based on the feedback.

Abstract: A system and method for underground gasification. A system for underground gasification system may comprise a recovery system, a supply line, and a downhole ignition device operable to ignite an underground energy source. The downhole device may be connected to the supply line and the supply line may be connected to the recovery system. The system for underground gasification may further comprise an information handling system that may be operable to control the downhole device. A method for igniting an underground energy source may comprise disposing a downhole ignition device into an injection well, positioning the downhole ignition device within the underground energy source, activating the downhole ignition device, igniting the underground energy source, and recovering a gas from the underground energy source.

Abstract: A system may include a downhole tool conveyable into a wellbore on a conveyance, and a plurality of sensing devices positioned at a distal end of the downhole tool to emit wave energy in an axial direction within the wellbore. At least a portion of the wave energy are reflected by one or more wellbore hazards and received by the plurality of sensing devices. The system further includes a data acquisition system communicatively coupled to the downhole tool to receive and process reflected wave energy and thereby identify the one or more wellbore hazards.

Abstract: A combined fluid pressure transducer and temperature sensor (10) has a housing (12) containing a variable capacitor (14) having a rigid substrate (14a) and attached flexible diaphragm (14b) in sealed, spaced apart relation. The capacitor is mounted in the housing so that the outer face surface of the diaphragm is exposed to a fluid pressure chamber (12k). A temperature responsive sensor element (28) is disposed on the outer face surface of the diaphragm and covered by a thin protective layer. A fluid flow diffuser (30) is disposed in the fluid pressure port (12b) for directing fluid flow across the temperature sensor.
