My current research

My research topic is mainly focused on the carbonate reservoir heterogeneity inversion by employing a pore structure parameter defined in Sun Model of poroelasticity. For a carbonate reservoir, diagenesis of carbonate rocks during deep burial greatly changes the depositional rock properties, and complicates the reservoir heterogeneity which will greatly influence ultimate field production. My investigation is to find out how to link permeability with seismic data so that after pore structure inversion the reservoir connectivity in inter-well regions can be better delineated for optimal reservoir management to maximize oil/gas production.

During the past academic years, I mainly worked on two aspects. The first one is the rock physics analysis based on the well logs data. The analysis shows that porosity, pore type and pore structure are the primary factors influencing the sonic velocity of carbonate rocks. For the same pore type, sonic velocity and porosity have a negative correlation. At a given porosity, carbonate rocks with vuggy pore type tend to have higher sonic velocity than those with inter-particle or inter-crystal pore type. Such difference results in different values of pore structure parameter. Thus by combining porosity and pore structure parameter, reservoir rocks can be mapped and their heterogeneity features can be understood. The second one is how to estimate porosity and pore-structure parameter simultaneously from pre-stack seismic data through inversion which is on-going.
