The faster a certain operation is performed without jeopardizing safety- the better. The caveat is that most of the operations are performed by human operators who go by their “gut feeling”. There is no way to guarantee that they would produce aconsistently good result, as they can get distracted, tired or just have a bad day. Using statistical inference, we were able to predict the optimal speed of a pump-down gun during perforation+fracturing (at 1 meter intervals throughout thewell), based on a record of prior pump-down operations, well shapes and geological information.Using the well geometry and the velocity probability distribution, we estimated time saved between the median of the run to the optimal run.
