New model presented for kinetic aquathermolysis

A paper saw light in Petroleum Science and Engineering.

A kinetic model is of great importance for future digital modeling of deposits. Moreover, the case in this paper helps adjust catalysts, predict reactions, and calculate the use of reagents.

“The work comprises our analysis of the distribution of reaction products to determine kinetic parameters for a better correlation with experimental data,” explains co-author Guillermo Félix, Research Associate of the In-Situ Combustion Lab.

The novelty of the study lies in the approach to the analysis of changes in heavy components (asphaltenes). The work provides an understanding of the interaction of oil with water vapor during its in-situ upgrading.

The research is coordinated by Professor Jorge Ancheyta of the Mexican Petroleum Institute. He notes, “We have examined in detail the changes in various fractions of oil. The innovative component of the kinetic model lies in the extensive disclosure of the composition of the liquid fractions of heavy oil, which until now remained unknown in aquathermolysis reactions.”

“The developed kinetic model can be used to predict changes in flow rates and composition of liquid products during in-situ upgrading of unconventional resources, including heavy, extra-heavy oil and natural bitumen, as well as to create a suitable hydrodynamic model of the well,” adds Junior Research Associate Ameen Al-Muntaser.
