The investigation and prediction of fractured systems for the analysis of non-conventional reservoirs are considered a challenge for geoscientists and engineers because data directly related to fractures are scarce. During the exploratory phases, fracture evaluation is even more critical.
This lecture discusses the utilization of tools and techniques more suitable to evaluation of fractures during exploration, considering that the approach commonly used in fractured reservoir studies during production is not applicable because the lack of well data and dynamic information. In order to avoid unrealistic DFN models, robust conceptual models become necessary for fracture prediction on exploratory stage. The models must take into account the deformation mechanism and evolution of the main structures associated with fracturing.
We will present a Petrobras case study on evaluation of Albian fractured carbonate oilfield at Campos Basin, in Eastern Brazilian continental margin, using a limited number of wells. The main purpose of this lecture is to point that during exploratory phases the integration of several methods allows the generation of a conceptual structural model, which can be used as a guideline for the development of the petroleum accumulation that depends strongly on fracture intensity and distribution.
About the lecturer
Raphael Hatushika graduated in geology in 2004 in Rio de Janeiro. He earned a master in stratigraphy with emphasis on tectonic and sedimentation in 2008. He joined Petrobras in Brazil in 2006 and has since worked with structural geology and tectonic analysis in the exploratory group of the company.
Who should attend
This lecture should be interesting to exploratory geologists and geophysicists, and also to geoscientists and engineers that works on fractured reservoir characterization.
