MEDINA-ERAZO, Oscar et al. Disaggregation and discretization methods for formation damage estimation in oil and gas fields: an overview. Dyna rev.fac.nac.minas [online]. 2020, vol.87, n.213, pp.105-115. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v87n213.84377.

Formation damage could potentially impede production and injection operations. Hence, characterization and discretization processes of formation damage should be connected to quantification and disaggregation techniques, relying on characterization fundamentals that consider chemical and physical changes in the fluid and rock system through the field productive life. This document presents a review of different disaggregation, quantification and discretization methods for the formation damage estimation in oil and gas fields. This review is mainly divided into three main sections, namely: i) Formation damage diagnosis, ii) Formation damage quantification, and iii) Formation damage disaggregation. This document will aid in the alignment of the academic and industrial sectors to incentivize the prevention and inhibition of formation damage, as well as the optimal design of remediation mechanisms.
