Abstract
Historically, oilfield development has been technically and economically challenging, primarily as a result of more complex reservoirs and difficult environments. One of the roles of a reservoir engineer who encounters these challenges is to provide fast and accurate scenario analyses for management to use for making decisions. During a reservoir scenario analysis process, data management tasks required to get all results in context for successful analysis are always a challenge for engineers to respond in a fast and accurate way, besides the numerical simulation time that is already highly time consuming.
This paper presents a workflow and an environment, developed and implemented for an offshore asset in Brazil, to support reservoir and planning engineers in the generation and analyses of operational scenarios and their management. The goals of this workflow include reducing time-consuming tasks with an automated process, and to facilitate and accelerate the flow of information among key decision makers.
The scope of this work includes case study requests, updating key files in the process, running simulations, processing results, and supporting historical scenarios management. It also incorporates an alternative for conventional numerical simulation with the use of proxy models that aid in the search for an optimum scenario of production and injection profiles.
The effect of the work is primarily focused on the support provided to the engineers to reduce the time required for data management tasks and to locate requested solutions more quickly. The time reductions are highly visible, especially in data management tasks, but they are significantly more important in optimization workflows, reducing the number of regular simulations required to determine the best operational profiles.
