Abstract: A method of modeling an oilfield network can include identifying a well and a tying point, identifying locations of the well and tying point, identifying elevations of the well and tying point, creating a model pipeline along a path between the well and the tying point, such as a straight line path between the well and the tying point, defining a length of the path, calculating an elevation difference between the well and the tying point, determining whether an obstacle exists in the path, and defining a length of the pipeline. A method can include creating a second path that circumvents the obstacle and adjusting a length of a pipeline accordingly. A method can include implementing one or more nudging algorithms and incrementally adjusting the length of a pipeline. A method can include defining one or more limits for adjusting a length of a pipeline model.

Abstract: Calculating wellbore energy. At least some of the illustrative embodiments are methods including: calculating an expected wellbore energy for a planned wellpath, the calculating by a computer system; calculating an expected tortuosity of the planned wellpath; calculating a first value indicative of probability of occurrence of a drilling event for drilling along the planned wellpath, the first value based on the expected wellbore energy and the expected tortuosity; and then drilling a wellbore along at least a first portion of the planned wellpath if the first value indicates the probability of the drilling event is less than a predetermined threshold.
