Abstract:
Wide changes in reservoir quality and abundant heterogeneity in reservoirs lead to the inherent difficulty of production and enhanced oil recovery from these reservoirs. This difficulty is the result of the influence of related parameters, including facies and sedimentary environment, diagenesis processes and tectonic transformation and basin morphology. The reservoir quality of a formation depends on diagenetic processes in addition to initial conditions of deposition. In fact, diagenesis is an important controlling factor in many hydrocarbon reservoirs. Many changes in the distribution of facies during diagenesis cause heterogeneity in oil and gas reservoirs. Investigation of diagenesis processes shows that the most important diagenesis processes affecting a geological formation are several generations of fractures and burial pressure dissolution and cementation, dolomitization and micriteization, compaction and compression (mechanical and chemical). Diagenesis, the process of transforming sediment into sedimentary rock, involves significant geochemical changes that are studied using geochemical methods. In this paper, effects of diagenesis processes on reservoir quality of a geological formation will be discussed.
