About:

Dr. Emami-Meybodi’s research and teaching centers on the fluid flow and transport phenomena in porous media, spanning both highly applied and fundamental aspects. His research focus is on the development and application of analytical and numerical methods aiming at enhancing fundamental understanding and on developing solutions, with a particular emphasis on applications to carbon capture, utilization, and storage (CCUS) and development of unconventional resources. He has conducted research on solutal and thermal natural convection, diffusive transport in tight rocks, dispersion in porous media, production data analysis for unconventional reservoirs, solvent injection in tight rock, waterflooding, chemical enhanced oil recovery (EOR), hydraulic fracturing, and asphaltene precipitation.

Research Projects: 

Solvent Injection in Ultra-tight Reservoirs
This project investigates a new and radically different approach to predict field-scale recovery for both the primary production period and any subsequent solvent-injection process in the ultra-tight reservoirs based on diffusion-dominated transport conditions within the matrix. In this project, the fluid transport in ultra-tight rock was considered as a diffusion process that should be modeled based on Fick’s law instead of the commonly used Darcy’s law. Although, the form of the equations for transport for both Fick’s and Darcy’s law are similar, the mechanism for transport is different in its nature: hydraulic conductivity controls transport in the Darcy’s law while molecular diffusion coefficient controls transport in Fick’s law and therefore any process that increases the diffusion coefficient will aid recovery. This is of critical importance because, unlike hydraulic conductivity, diffusion coefficient can be enhanced by selecting solvents that increase diffusion coefficients. In addition, the mechanism for hydrocarbon recovery is based solely on density and concentration gradients.

Capillary Trapping Controlled by Geochemical Reactions in Porous media
The purpose of this project is to develop and apply theoretical and experimental tools to understand nonwetting phase trapping controlled by the interplay of geochemical, dissolution, and multiphase flow processes at the pore scale by conducting long-term experiments at geologic pressure and temperature. Multiphase flow in porous media is constituted by a rich set of phenomena that are commonly expressed as hysteresis and irreducible residual saturations of wetting and nonwetting phases during primary drainage and imbibition. Extensive characterization has been carried out on the primary flow processes. However, the geochemical impacts on partially miscible flow processes where some species from the nonwetting phase can be dissolved in the wetting phase are not well understood beyond the primary flow processes.

Production Data Analysis of Unconventional Reservoirs
This project aims at the development of analytical solutions to flow equations used in the rate transient analysis (RTA) techniques by relaxing some of the assumptions previously made, such as single-phase flow and using of simple fracture geometry. The emphasis will be placed on low- (tight gas) and ultra-low-permeability (shale gas) reservoirs. The main areas of focus are (1) multi-phase flow that includes the transition of fluid flow from single-phase (gas or oil) to two-phase (gas and condensate or oil and gas) and three-phase (inclusion of water) flow, (2) multiphase flowback RTA, and (3) more complex conceptual models that represent real scenarios. Accurate and large-scale numerical simulations of hydrocarbon production and analysis of well performance are computationally very expensive. Therefore, the development of analytical and semi-analytical models that can be used to accurately evaluate and predict the reservoir performance is of critical importance.
