Abstract
A method involves obtaining a current production rate, obtaining a current wellhead pressure, computing a current smoothed production rate from the current production rate, computing a current smoothed wellhead pressure from the current wellhead pressure, predicting based on the current smoothed production rate, the current smoothed wellhead pressure, and the current surface choke size, a future smoothed production rate and a future smoothed wellhead pressure, computing a change of the future vs the current smoothed production rate, and computing a change of the future vs the current smoothed wellhead pressure. The method further involves comparing the change of the future vs the current smoothed production rate against a first pre-specified threshold production rate derivative, comparing the change of the future vs the current smoothed wellhead pressure against a first pre-specified threshold wellhead pressure derivative, and based on an outcome of the comparison, determining whether future sanding is detected.
