A Robust Model for Integration of Sand-Arch Stability and Fractal Wormhole Network in CHOPS and post-CHOPS Process Simulation
DownloadSpring 2024
Cold heavy-oil production with sand (CHOPS) is a primary recovery process in unconsolidated heavy-oil reservoirs. The recovery factor typically ranges from 5% to 15% of the initial oil in place (OOIP). Approximately 90% of crude oil is left underground with considerable exploitation potential...

Development of Solvent Selection Criteria Based on Diffusion Rate, Mixing Quality, and Solvent Retrieval for Optimal Heavy-Oil and Bitumen Recovery at Different Temperatures
DownloadFall 2015
Heavy-oil and bitumen recovery requires high recovery factors to offset the extreme high cost of the process. Attention has been given to solvent injection for this purpose and it has been observed that high recoveries are achievable when combined with steam injection. Heavier (“liquid”) solvents...

Spring 2016
Solvent injection is a widely used method to enhance oil recovery (EOR). Mixtures of reservoir oil and solvents can exhibit complex multiphase behavior at temperatures typically below 120°F, in which a third solvent-rich liquid (L2) can coexist with the oleic (L1) and gaseous (V) phases. Reliable...

Fall 2017
As a follow-up method after CHOPS (Cold Heavy Oil Production with Sands), CSI (Cyclic Solvent Injection) was widely accepted in the oil industry. After injected gas solvents with high pressure are dissolved in a heavy-oil reservoir, produced oil shows dispersed gas-phase in the oil, which is...

Stability and Mobility of Foam Generated by Gas-Solvent/Surfactant and Gas-Solvent/Nanoparticles under Reservoir Conditions
DownloadFall 2016
Foam can be a feasible means to remedy the low sweep efficiency of solvent flooding (e.g., CO2 and/or C3H8) resulting from viscous fingering and gravity segregation. It works as a good mobility control agent that decreases the mobility difference between the displaced oil and the displacing...

Wettability Alteration by Chemical Agents at Elevated Temperatures and Pressures to Improve Heavy-Oil Recovery
DownloadFall 2017
The thermal method is the primary method used to improve the recovery from reservoirs with heavy or extra-heavy oil. However, the efficiency and economic costliness of the traditional thermal process are limited by the unfavorable interfacial properties of heavy oil/water (steam)/rock system....

Zwitterionic Surfactant for EOR in Tight Carbonate Reservoir: Physico-Chemical Interaction and Microfluidic Study
DownloadFall 2019
Recently, during surfactant aided recovery processes for unconventional reservoirs, carboxybetaine based zwitterionic surfactants (CnDmCB) have attracted attention due to their good tolerance to high saline produced water, remarkable water solubility, and ultra-low interfacial tension (IFT) at...
