Abstract
Here, we show the processes carried out and results of a diagenetic process analysis and geophysical characterization of pore types in Jurassic and Cretaceous carbonates in the TS oil field, Gulf of Mexico. In order to make predictions, we carried out a rigorous petrophysical evaluation and used borehole image interpretation, core analysis and thin section observations. This information was used in the construction of rock physics models that consider various arrangements of pore shape and fracture concentration. Once the physical links between the micro structural properties (type and shape of the pores) and elastic properties were established, we proceeded to make connections with attributes obtained by seismic inversion processes. These connections were formed using a probabilistic approaches where the results are volumes of intercrystaline porosity, dissolution porosity and fracture porosity.
