Abstract: Methods, systems, and computer-readable storage media for resource-efficient generation of a workover rig schedule by receiving well data and workover rig data for wells, each well producing oil, determining sets of schedules by, for each schedule in a set of schedules, incrementally: calculating a virtual gain for each well in a set of remaining wells, each virtual gain being a function of a production gain for a respective well, a travel time of a workover rig to travel from a current well to the respective well, a workover time for the respective well, a first parameter applied to the workover time, and a second parameter applied to the travel time, and selecting a well as a next well in a schedule based on a respective virtual gain; identifying, from the sets of schedules, a schedule having a maximum cumulative gain, and outputting the schedule as an optimal schedule.

Abstract: Technologies are described for determining a loading arrangement for hollow circular pipes. Determining the loading arrangement can comprise determining an optimal telescopic arrangement for a plurality of hollow circular pipes. Determining the optimal telescopic arrangement can comprise determining a concentric telescopic arrangement and determining a radial telescopic arrangement. Groups of hollow circular pipes can be generated based on the concentric telescopic arrangement and the radial telescopic arrangement that specifies which of the hollow circular pipes will be arranged within each other concentrically and which of the hollow circular pipes will be arranged within each other radially. The loading arrangement can be determined that includes the optimal telescopic arrangement. The loading arrangement can also indicate how the groups of hollow circular pipes will be loaded into a container for shipment.
