Advanced Nodal Analysis for Production Engineers

Based on data coming from a material balance or the own production of a well, it is possible to predict the future production behavior of a well as a function of time and decide the proper selection of design variables such as tubing sizes for example, or make the decision to install or not any particular artificial lift system. Unlike a conventional nodal analysis, all decisions from a sensitivity analysis is carried out and planned in the future considering the reservoir pressure changes that happens with time.
