While Carbon Dioxide based Enhanced Oil Recovery (CO2 -EOR) is often regarded as one of the most economically viable methods carbon capture, utilization and storage (CCUS), little known about existing CO2 supply contracts in -EOR industry. By studying a sample 103 sales U.S. 1980s 1990s, this paper aims to find out what drives key terms these contracts. In particular, special price adjustment c...

Water-oil relative permeability characterizes two-phase flow and displacement processes, and its functional form is difficult to determine in a particular reservoir study. Adding various chemical agents into the displacing aqueous phase during alkaline-surfactant-polymer combination chemical flooding in oil production significantly changes interfacial tension (σ) on water-oil interfaces, and al...

The Farnsworth Unit in northern Texas is a field site for studying geologic carbon storage during enhanced oil recovery (EOR) using CO2. Microseismic monitoring essential risk assessment by detecting fluid leakage and fractures. We analyzed borehole microseismic data acquired CO2 injection migration, including denoising, event detection, location, magnitude estimation, moment tensor inversion, ...

Cryogels from noble metal NPs have proven to be highly efficient catalysts due their high specific surface area which increases the mass transfer channels and catalytic active sites. By using oxides as co-catalysts, costs of material can significantly reduced, while activity remain same or even improve synergetic effects. In this work, we synthesize different cryogel thin films supported on mod...

Abstract With the growing demand for energy supply and natural decline of oil reservoirs, development new enhanced recovery (EOR) techniques become more critical. Polymer flooding EOR is one most successful chemical methods but suffers many drawbacks at high temperatures salinity (HT‐HS) conditions. Superparamagnetic nanoparticles (NPs) have been recently investigated subsurface applications, i...
