The formation of low-viscosity emulsions is a vital method for viscosity reduction of crude oil. Naphthenic acids, which are present in crude oil, are potential surface-active substances. Tertiary amines with CO2 response can be self-assembled in…
Distinct naphthenic acid (NA) species were isolated from oil sands process water (OSPW) into 20 fractions via silver-ion solid phase extraction, prior to treatment using potassium ferrate(VI). Untreated and treated fractions F1F20 were characterized…
Hydrogen (H2) as a cleaner fuel has been suggested as a viable method of achieving the de-carbonization objectives and meeting increasing global energy demand. However, successful implementation of a full-scale hydrogen economy requires large-scale…
Underground hydrogen (H2) storage (UHS) and carbon dioxide (CO2) geo-storage (CGS) are prominent methods of meeting global energy needs and enabling a low-carbon global economy. The pore-scale distribution, reservoir-scale storage capacity, and…
Abstract: A comparative analysis has been made of the physicochemical properties and structural-group composition of acids isolated from crude oils of the Anastasievsko-Troitskoe (Krasnodar krai, Russia) and Naftalan (Azerbaijan) oil fields. For each…
Naphthenic acids and sulfur compounds present in crude oils may cause corrosion in oil refineries. In some cases, corrosion product scale formed in these oils may provide corrosion protection, but in other cases this may not be true. Current research…
In H2, CO2 and natural gas geo-storage, rock-fluid interfacial tension (rockfluid) is a key parameter which influences pore-scale fluid distribution and reservoir-scale gas storage capacity and containment security. However, rockfluid data is…
CO2 injection contributes to formation energy supplement to remedy the fast production decline in tight oil reservoir and CO2 storage at the same time.CO2 Here, we report CO2-water relative permeability with consideration of acid-rock reaction. The…
To efficiently remove Ni from crude oils and also without corrosion occurring in the process, polymer brush with core-shell structure (PAA@SiO2) was synthesized by radical polymerization, in which micro-sized SiO2 as the core and polyacrylic acid as…
The main problem dehydration system of XinMu Oil Field at present is high dehydration temperatures,high the amount of demulsifier, increase output moisture content year by year and more and more frequent fluctuations.Through the reform to establish a…
Given the ill-defined term “naphthenic acids” (NAs), we will classify NAs as the carboxylic acids found naturally in crude oil, which include both classic NAs (c-NAs, monoacids) and ox-NAs (polyacids). Resulting from the biodegradation mainly of…
Adopting nature-based solutions for the bioremediation of oil sands process water (OSPW) is of significant interest, which requires a thorough understanding of how bacterial communities behave within treatment systems operated under natural…
This work aims to evaluate the use of petroleum as a solvent in the liquid-liquid extraction of oil and grease content from oilfied produced water. Initially, tests were performed with synthetic effluent, using cyclohexanecarboxylic acid as model…

Hypothesis Millions of tons of CO2 are stored in CO2 geological storage (CGS) formations (depleted oil reservoirs and deep saline aquifers) every year. These CGS formations naturally contain small concentrations of water-soluble organic components in…
