Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to wirelessly configuring bottom hole assemblies (BHAs) for use in coiled tubing well operations. For example, certain embodiments of the present disclosure include a method that includes wirelessly communicatively coupling at least one user computing device to a wireless access point of a wireless access module of a BHA. The method also includes wirelessly receiving one or more command signals from the at least one user computing device via the wireless access point of the wireless access module of the BHA. The method further includes adjusting one more operating settings or procedures of one or more downhole tool components of the BHA based at least in part on the one or more command signals.

Abstract: A technique facilitates use of an actuator with a locking feature enabling selective locking of the actuator in a desired operational position. For example, the actuator may comprise a mandrel which can be used to shift a tool between operational positions. The mandrel is surrounded by a housing which creates a cavity. A magneto rheological fluid is disposed within the cavity and operates in cooperation with the mandrel to enable selective locking of the mandrel at a desired operational position or positions. Magnetic field can be generated via an electromagnetic coil or a permanent magnet to selectively increase the viscosity of the magneto rheological fluid to lock the mandrel at the appropriate operational position.

Abstract: An element is deployed within tubing extending to a downhole tool. The downhole tool includes a hydraulic tool and a valve coupled between the conveyance string and the hydraulic tool. The valve includes a valve seat having a passage directing the fluid from the conveyance string to the hydraulic tool. Deploying the element includes landing the element on the valve seat such that the element substantially obstructs flow of the fluid through the valve seat passage. The valve is opened to direct the flow of the fluid around the hydraulic tool, wherein opening the valve utilizes pressure generated in response to the element obstructing the flow of the fluid through the valve seat passage. At least a portion of at least one of the element and the valve seat is then degraded by an amount sufficient to permit the element to pass through the valve seat passage.

Abstract: Pumps for conveying fluid at a wellsite, such as fracturing or other stimulation pumps, are instrumented with sensors to measure or estimate pump parameters. In some instances, pump sensors are used to detect wear or failure or assess remaining useful life of pump components. The sensors can also or instead be used to assess, and in some cases optimize, pump performance.

Abstract: An assembly for inclusion in a tool string conveyed via coiled tubing within a wellbore. The assembly includes a mandrel having a passage for receiving fluid via the coiled tubing. The assembly further includes a packer disposed about the mandrel and expandable into sealing contact with a wall of the wellbore in response to receiving the fluid from the passage. The assembly also includes a flow control device controlling flow of the fluid from the passage into the packer. The flow control device includes a degradable material that is reactive to the fluid.

Abstract: A downhole tool conveyed via tubing within a wellbore at a wellsite comprises a hydraulic tool driven by fluid pumped to the hydraulic tool via the tubing. The downhole tool further comprises a valve in fluid communication between the tubing and the hydraulic tool. The valve is configurable in the wellbore between an expanded position, establishing a bypass diverting at least a portion of the pumped fluid away from the hydraulic tool, and a compressed position, closing the bypass.
