Abstract: Systems and methods presented herein facilitate coiled tubing operations, and generally relate to automatically improving performance of coiled tubing operations in substantially real time by inferring reservoir pressure based on initial coiled tubing run conditions. For example, a method includes performing a coiled tubing operation via a coiled tubing system at least partially disposed within a wellbore. The method also includes detecting data relating to operating parameters of the coiled tubing operation via sensors of the coiled tubing system during the coiled tubing operation. The method further includes determining an initial wellbore fluid distribution in the wellbore based on the detected data prior to pumping fluid into the wellbore from a surface location relative to the wellbore. In addition, the method includes inferring a reservoir pressure of a hydrocarbon-bearing reservoir through which the wellbore extends based on the initial wellbore fluid distribution in the wellbore.

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 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: Methods of performing a stimulation operation at a wellsite are disclosed. The wellsite is positioned about a subterranean formation having a wellbore therethrough and zones thereabout. The method involves establishing at least one objective for stimulating production of reservoir fluid from the subterranean formation and into the wellbore. The stimulating involves placing a stimulating fluid along the zones of the wellbore. The objective is based on wellsite data. The method also involves identifying at least one constraint for the stimulating, determining target distributions of the stimulation fluid based on the objective(s) and the constraint(s), and selecting operational parameters for the stimulating based on the constraint(s) and the target distributions. The method may also involve stimulating the subterranean formation using the target distributions and the operational parameters, monitoring the wellsite during the stimulating, and adjusting the stimulating based on the monitoring.
