Mineralogical Characterization for Optimizing Production of Reservoirs Azulita and Caparo Ceuta Field

Abstract

The detailed methodologies for the mineralogical characterization is valuable and should be taken into account in the optimization of oil over the life of the reservoir. This study included mineralogical and diagenetic analysis in units B-6, B-7, C-2 and C-3 Training Misoa, Campo Ceuta. We performed a detailed microscopic analysis in 3 cores to determine the mineralogical composition and intrinsic changes affect the productivity and quality of rocks and reservoir. The quality of rock is influenced by the clay, as well as post- depositional changes. The base unit B-6, have good quality rock, but it has kaolinite as clay migration and is the cause of low productivity in well AZ-1. AZ-2 Well, sanding presents problems due to instability in the quartz particles, presence of clay mixed between contacts, which makes the rock this low cohesion between the particles. Well AZ-3, introduced rock quality problems due to sediment compaction experience which decreases the porosity and permeability, and the possible presence of a bituminous material.
