Traditionally, well costs are estimated by using a deterministic calculation procedure with time and cost inputs, or by using probabilistic methods. Because in many cases the estimate determines whether or not the well will be drilled, the credibility of the estimated cost is crucial.This paper describes the development of a support vector machine (SVM) -based application. In addition to estimating the cost, this application also indicates the percentage of accuracy in the prediction, thereby proving the credibility of the predicted cost estimate. The proposed methodology enables drilling industry personnel to estimate the risk of the project during well planning and during drilling. The analysis from such a model is based on the constraints of different drilling variables. Extensive simulations have been carried out and are reviewed in this paper. The paper also includes two case studies of well cost estimation where the SVM methodology successfully the predicted risk involved in the completion of the wells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
