Abstract: Methods, systems and products for evaluating a downhole component condition for a drilling assembly in a borehole. Methods include estimating a bending moment on the component at a selected depth along the borehole; estimating a number of rotations of the component at the selected depth; and estimating the condition of the component using the estimated bending moment and the estimated number of rotations at the selected depth. Estimated bending moment may be derived from a borehole model using an estimated deviation on a selected length of the borehole about the selected depth. The condition may be accumulated fatigue or estimated remaining useful life. Estimating the condition may include tracking a total estimated number of rotations wherein the component is subjected to bending moment values in a corresponding moment window, which may be greater than a predetermined threshold bending moment. Weight factors may be associated with at least one moment window.

Abstract: Systems and techniques are described for performing workflow-based project management. An embodiment can receive a scope tree and a sequence of steps, stages, and/or phases that one or more items in the scope tree go through. The embodiment can then generate a set of subprojects, streams, and/or tasks based on the received scope tree and the sequence of steps, stages, and/or phases. Note that each subproject, stream, or task is associated with an item in the scope tree and an item in the sequence of steps, stages, and/or phases. Next, the embodiment can generate a set of interdependencies between the set of subprojects, streams, and/or tasks based on the scope tree and the sequence of steps, stages, and/or phases. The embodiment can then create the project plan that includes the set of subprojects, streams, and/or tasks and the set of interdependencies between the set of subprojects, streams, and/or tasks.

Abstract: A method on a computer for providing critical chain-based project management is disclosed. The method includes receiving at least one project plan for a project comprising a plurality of tasks and calculating a task priority for each of the plurality of tasks based on the at least one project plan. The method further includes receiving at least one sub-task for a first task of the plurality of tasks and assigning the at least one sub-task a task priority identical to the task priority of the first task. In one alternative, the method further includes receiving a new task priority for the first task, assigning the new task priority to the first task and assigning the new task priority to the at least one sub-task of the first task. The method may also include an interface to allow starting of sub-tasks only when the parent task is started.
