... operations can reduce both natural gas cost and cap-and-trade penalties. And because this process reduces the carbon intensity of the produced crude oil, the producer can earn low carbon fuel standard credits through the innovative crude provisions in the rule. Application of the technology described...

... investigated in the presence of crude oil. Foam performance was evaluated in carbonate core samples under different foam qualities and at reservoir conditions. After selecting the optimal foam quality for effective foam generation, the oil recovery experiment was then performed to recover the remaining oil...

... Abstract New technology and energy production have been fundamental staples for improving our quality of life, creating jobs and expanding a vibrant U.S. and global economy. Fossil resources like crude oil and natural gas have been essential for accomplishing this. Main uses have been to fuel...

... to the ability to both enhance oil recovery and store the CO 2 in the formation. Even though several shale plays have reported an increase in oil recovery using CO 2 injection, in some cases this method failed severely. This research attempts to investigate the ability of the CO 2 to mobilize crude oil from...

... were screened in static tests to generate foam in the presence of a water-soluble/oil-soluble solvent and heavy crude oil from a Canadian oil field (1600 cp). The liquid phase of NGS-foam contains surfactant, nanoparticle, and green solvent (GS) all dispersed in the water phase. Nitrogen was used...

... Abstract The description of chemical kinetics is very import to the simulation of reactive transport for enhanced oil recovery (EOR). Characterizing petroleum ignition is especially important for simulation and prediction of In-Situ Combustion (ISC). In order to model crude oil oxidation...

... and their blends with anionic, non-ionic, and zwitterionic cosurfactants were shortlisted based on the aqueous stability tests. Polished shale chips from Eagle Ford and Wolfcamp formation were made oil-wet by aging them with crude oil at 85 °C for 30 days. Contact angle experiments revealed that these synergistic...

... application in a particular oil field for cost-effective enhanced oil recovery (EOR) approach. In this article, optimization of the ASAG flooding in an Upper Assam oilfield was studied through lab-scale core flood experiments. First, reservoir core samples, crude oil, and formation water of the oilfield were...

... Abstract Coinjecting of steam with surfactant to recover heavy crude oil is studied. Performance production of this process is achieved through analysis of the formed emulsions which provides mechanistic understanding of crude oil and surfactant interaction in the presence of steam...

... candidate. This study focuses on identifying the components of the crude oil which primarily contribute to heat generation under the influence of the microwave. Pinpointing what makes the oil a more effective microwave receptor enables the optimization of desirable traits in the oil phase. Three different...

... heating rate crude oil kinetic cell experiment Introduction In-situ combustion (ISC) is an enhanced oil recovery (EOR) method in which air is injected into a reservoir to burn small amount of the crude oil to generate heat, thus driving the remaining oil towards the producers ( Sarathi, 1999...

.... tertiary polymer flooding for viscous oil recovery in an oil-wet 2D, layered, heterogeneous system. It focuses on performing flow visualization to capture the effect of cross-flow and viscous fingering in both modes. First, contact angle experiments were performed to ensure that the reservoir crude oil...

... crude oils were different and they showed high (low lighter component content) and slight (high lighter component content) biodegradation. In terms of produced oil quality, highly biodegraded oil sample responded to ISC better than the slightly biodegraded oil sample. Steam processes upgraded the highly...

Once the cores were prepared such that stress and pore pressure could be appliedin an API RP 19B Section 4 configuration...

... Abstract Microwave heating has great potential to recover heavy oil reservoirs, because it significantly reduces the heating time and consequently the cost of heavy oil extraction. Moreover, heavy crude oils contain high amounts of polar molecules (asphaltenes) and polar functional groups...
