This paper intends to show how two different methodologies, a Monte Carlo simulation method and a connectionist approach can be used to estimate the total time assessment in drilling and completion operations of oil wells in deep waters. The former approach performs a Monte Carlo simulation based on data from field operations. In the later one, correlations(More)
Scale deposition can damage equipment in the oil & gas production industry. Hence, the reliable and accurate prediction of the scale deposition rate is critical for production availability. In this study, we consider the problem of predicting the scale deposition rate, providing an indication of the associated prediction uncertainty. We tackle the problem(More)
The present work focuses on the development of a simulation method which provides an engineering tool for managing the risks associated with the development of an oil field. The developed method consists of performing discrete simulation based on data from field operations. The paper reports and discusses the simulation results of a real field development(More)
Data-driven learning methods for predicting the evolution of the degradation processes affecting equipment are becoming increasingly attractive in reliability and prognostics applications. Among these, we consider here Support Vector Regression (SVR), which has provided promising results in various applications. Nevertheless, the predictions provided by SVR(More)
In order to comply with safety requirements and due to the increasing demand on oil production, failure prediction of the related systems (e.g. oil wells) has become an important task. An analytical modelling of the reliability behaviour of these systems is often impractical and this justifies the use of data-driven learning methods like Support Vector(More)
This article presents an ongoing research that addresses the optimization of the cost of drilling wells in environments of high complexity and risk such as those related to the pre-salt region offshore Brazil. The minimization of these costs is directly related to the maximization of ROP (Rate of Penetration). The metric cost, i.e., the cost per meter of(More)
Nearly every well installation process nowadays relies on some sort of risk assessment study, given the high costs involved. Those studies focus mostly on estimating the total time required by the well drilling and completion operations, as a way to predict the final costs. Among the different techniques employed, the Monte Carlo simulation currently stands(More)
