Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to the use of flow modeling to generate flow-related data that cannot be measured in order to take re-al-time decisions and real-time predictions on the outcome of future potential actions to be taken by engineers or artificial intelligence to optimize operation performance together with a general method for parameter inference for any uncertain parameters deemed important when designing cleanout operations. In certain situations, a pre-conditioning method for the determination of a reservoir pressure parameter may be used to reduce the effect of its uncertainty on design fidelity. In addition, in certain situations, a pre-conditioning method for the determination of a reservoir inflow performance parameter may be used to reduce the effect of its uncertainty on design fidelity.

Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to coiled tubing simulators that capture decades of expertise. In particular, the various simulators are formulated as a simulator graph search problem that enables optimal querying of the simulators (e.g., maximizing confidence and efficiency). The representation for a simulator graph is built and integrated with AI planning, constraint satisfaction programming (CSP), reinforcement learning (RL), and execution, which includes three main steps: (1) creation of a simulator graph that encodes the relations between inputs and outputs of different simulators. (2) integration of the simulator graph with an AI planner, CSP and RL, and (3) plan execution and monitoring of the plan with dynamic re-planning, as needed.

Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to the use of mechanical models for the automation of such coiled tubing operations in the oil and gas industry. In particular, a framework is presented that includes three main building blocks: (1) a probabilistic tubing force and depth estimation package; (2) an anomaly detection package; and (3) a mechanical failure check package, each of which are software packages executable by a surface processing system.

Abstract: Systems and methods are provided for detecting potential failures in logging winch systems to enable efficient maintenance are provided. An example of such a system may include a logging winch system that conveys a downhole tool into a wellbore on a cable and a data processing system. The logging winch system may include sensors that measure observed quantities relating to operation of the logging winch system. The data processing system may determine correlation signatures that relate the observed quantities to the operation of the logging winch system and may identify when one or more of the correlation signatures indicates abnormal operation.

Abstract: A winch controller for a hoisting apparatus for a wireline operation operates as a closed loop controller. The winch controller is adapted to control a winch or, if included, a winch and a capstan in a coordinated manner. The winch controller may utilize process variables including the tension of the cable between the winch and the capstan. The controller is coupled to a power pack adapted to power the winch and capstan. The power pack and controller are configured such that the capstan may be selectively removed from the system when it is not needed.

Abstract: Oil field services apparatus and method. The apparatus comprises a conveyance system operable for lowering and retrieving a downhole tool in and out of a wellbore. The conveyance system comprises a drum operable for rotating and receiving a line connectable with the downhole tool, a motor-generator mechanically connected with the drum, and an energy storage electrically connected with the motor-generator. The motor-generator may be operable for receiving electrical energy to impart torque to the drum and receiving torque from the drum to generate electrical energy. The energy storage may be operable for storing electrical energy received from the motor-generator.
