Project Description

The project is developing improved tools and techniques to assess and validate fluid flow in tight, fractured reservoirs resulting in an ability to better characterize and determine the storage capacity for CO2 and enhanced oil recovery (EOR) potential of tight oil formations. Specifically, the project is developing methods to better characterize fractures and pores at the macro-, micro-, and nanoscale levels, identifying potential correlations between fracture characteristics and other rock properties of tight oil formations, correlating core characterization data with well log data to better calibrate geocellular models, and evaluating CO2 permeation and oil extraction rates and mechanisms.

Project Benefits

This research will better assess and validate CO2 transport and enhanced oil recovery in tight oil formations using the Middle Bakken reservoir as an analogue for assessing EOR and storage in fractured tight reservoirs, and the oil-wet shales of the Upper and Lower Bakken will be used to assess the CO2 retention and EOR ability of similar shale formations throughout the world. Improved understanding of the factors that control CO2 transport and EOR operations within tight oil formations and the incorporation of those factors into geologic and simulation models will develop a more accurate prediction of CO2 EOR potential, CO2 storage capacity, CO2 storage efficiency, and CO2 storage permanence. Specifically, this project will develop tools to identify and evaluate fracture networks, correlate fracture networks with other geochemical and geomechanical factors, evaluate CO2 transport within a tight oil formation, and assess oil-wet rocks as confining zones for permanent CO2 storage.
