Abstract Inaccessibility to direct pore scale observation in hydrocarbon recovery of tight shale formations poses a great challenge to water-energy nexus initiatives and necessitates the use of high throughput technologies to emulate environmentally friendly processes. Herein, we employ a precise glass micromodel fabrication and visualization method to isolate the supercritical CO2 bubbles surrounded by CO2-water lamella prepared in saline produced water stabilized with molecular complexation of...

Abstract Huff-n-puff (HnP) gas injection has proven to be effective for recovering more liquid hydrocarbons from shale oil reservoirs. However, effective simulation of HnP requires a better understanding of the complex microstructure of shales and the multi-scale pore systems. An integrated workflow is developed that identifies multicomponent grains and pores types in the Lower Eagle Ford (LEF) shale at different depths, and distinguishes depositional kerogen from migrated organic matter (bitume...

Abstract Fracture complexity, variation in fluid properties, variations in rock types and diffusion of gas from the fracture into the oil-saturated nano-pores are the main contributing factors in oil recovery using gas huff-n-puff injection. Limited research has been conducted to define diffusion coefficients coupled with rock tortuosity resulting in calculation of effective diffusion. The objective of this work is to conduct a comprehensive experimental and simulation study on lower Eagle Ford ...

Abstract Injection of modified salinity brines (MSB), i.e. brine with seawater-like salinity (SWS) and low salinity water (LSW) in oil-wet carbonate rocks has proven to be relevant to improved oil recovery operations. Many reports in the literature related the underlying mechanisms to rock-fluid interactions such as ionic exchange and electrical double layer expansions, which caused wettability alterations at the rock surface. Little attention appears to have been paid to fluid-fluid interaction...

Abstract This review analyses the fundamental thermodynamic theory of the crude oil-brine-rock (COBR) interface and the underlying rock-brine and oil-brine interactions. The available data are then reviewed to outline potential mechanisms responsible for increased oil recovery from low salinity waterflooding (LSWF). We propose an approach to studying LSWF and identify the key missing links that are needed to explain observations at multiple length scales. The synergistic effect of LSWF on other ...
