Análise petrofísica da área nordeste do campo de Peregrino, Bacia de Campos Brasil

Abstract

The present work aims to identify electrofacies based on profile profiles in the northeast area of the Peregrino field, Campos Basin, Brazil. This oil field is located of Cretaceous sandstones of the Carapebus Formation (Upper Cretaceous) deposited in great majority directly on the Gp. Macaé by gravitational flows (turbidity and debris) in distal marine environment. The characteristics of these sands vary substantially throughout the strike of the field, from hardened layers of clean sandstones with high porosity and permeability with thin layers and highly bioturbated. The material available was logging while drilling of eleven horizontal wells, wireline data and some laboratory analyzes, as well as production test data from an exploration well, were available for this work, EXP-1-RJS. Eight horizontal wells are in production, three of these horizontal wells were abandoned and the exploration well was drilled by Petrobras being the first well in the field. The workflow consisted in the identification and characterization of these electrofacies based on the profiles and calibrated with the data of profiling and laboratory of the exploratory well. Concluding possible geological models for the Peregino oil field
