Digital Assistants for 3D Geomechanical Modeling: an Application for a Pre-salt Carbonate Field

Abstract

Summary Reservoir geomechanical studies support important decision makings, as operational security limits and production optimization, bringing value to the petroleum company that owns the referred field. The reliability of the geomechanical analyses is dependent on both premises and methodologies chosen to model and fit the problem, as well as the representativity of the hard data used to fit the model. Over the last 15 years, Petrobras has developed important digital tools and software solutions with great impact on reservoir geomechanical studies. Even though, the construction and update of a geomechanical model is still a costly task. Petrobras has developed digital modeling tools integrated with the company’s databases, implying the enhancement of the specialist work responsible for the model construction. This paper describes the application of one of these digital tools, the one that generates finite element meshes, applied to a pre-salt carbonate field. With this digital tool, a mesh can be generated in only 15 minutes, resulting in more flexibility and agility to the geomechanical model construction process.
