Selección de tratamientos químicos para recobro mejorado a partir de metodologías multicriterio
, 2019 This research presents a decision methodology to select a chemical treatment for enhanced oil recovery in a specific field. The proposed decision algorithm combines Analytic Hierarchy Process (AHP), Fuzzy Logic (FL), and Genetic Algorithms (GA) for determining the relative importance of criteria, and then with the Technique for Order of Preference by ...

Perfil de invasión de un surfactante aniónico en procesos de recobro mejorado
, 2019 The retention of surfactant in the porous medium is one of the factors that affect the development of an EOR process because the greater amount of the surfactant remains in the vicinity of the face of the well preventing it from acting in depth, which It represents high costs for the realization of this type of projects.

, 2019 Surfactant flooding is a common procedure for enhancing oil recovery. However, this chemical-based oil recovery method is affected by the large quantity of chemical loss inside the reservoir. This work proposes the use of mesoporous silica nanoparticles (MSNPs) widely studied in nanomedicine as carriers for active compounds to controlled delivery and ...
