Abstract: In this paper, we address the problem of inaccuracy in evaluating bottom hole circulating pressure (BHCP) in the petroleum industry by proposing a new predicting scheme. This scheme utilises a modified version of the stem cells algorithm (MSCA), recently introduced as a powerful meta-heuristic optimisation method, along with the back propagation (BP) training strategy to build a three-layer artificial neural network (ANN) as a predictive scheme. This new method is able to predict the complex relationship between inputs and outputs of a highly nonlinear system such as BHCP more accurately. The results by applying the proposed method compared with those by applying previous predicting methods used for BHCP demonstrate the superiority of the proposed method in terms of accuracy and time consumption.
