A Computer Simulation of a Laboratory Coreflood , Using TRSl0-80 Surfactant in Berea
… characteristics observed in an experimental coreflood conducted by a previous investigator (Looney) which used a TRSl0-80, Nonane, Isopropyl Alcohol, 1.0 wt. % NaCl Brine Slug. Since sodium and calcium concentrations were not measured in the coreflood effluent, and the effect of calcium on …

Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,
… for the pendant oil drop case. Finally, five coreflood tests were performed to determine the optimum timing for miscible CO2-EOR after waterflooding and six coreflood tests were conducted to examine CO2-soaking effect on miscible CO2 flooding in a tight sandstone formation, respectively. The …

Qualitative and Quantitative Technical Criteria for Determining the Minimum Miscibility Pressures from Four Experimental Methods
… experimental methods, i.e., the slim-tube tests, coreflood tests, rising-bubble apparatus (RBA), and vanishing interfacial tension (VIT) technique. First, five slim-tube tests with the live light crude oilCO2 system and five coreflood tests with the dead light crude oilCO2 system are conducted …

Optimization of chemical enhanced oil recovery methods for naturally fractured carbonate reservoirs
… methods for naturally fractured carbonates. Coreflood experiments and the UTCHEM reservoir simulator were used to investigate alkali-surfactant flooding in fractured Texas Cream limestone cores. A decrease in fracture mobility caused by viscous phase trapping in the fracture was identified as …

Low Interfacial Tension Foam Miscible Ethane Oil Recovery in Low Permeability Harsh Environments
… conditions. Subsequent foam quality and coreflood displacement tests were conducted to compare the recovery efficiencies of three processes: a) gravity–unstable, miscible ethane foam; b) gravity–stable, miscible ethane, and; c) gravity–unstable, miscible ethane processes.

Effect of surfactants and brine salinity and composition on spreading, wettability and flow behavior in gas-condensate reservoirs
… and pressure drop data obtained from the coreflood experiments using Berea sandstone core. Wettability was altered from strongly oil-wet to intermediate-wet by the anionic surfactant. The declining trend of spreading coefficient resulted from the presence of surfactants indicating the …

Performance Of A Novel In-Situ HCl For Carbonate and Sandstone Reservoirs
… of aging cell tests will be investigated first. Coreflood experiments will be modified (flow rate, injected PV of acid, different additives etc.) accordingly, and results of elemental analysis of effluent samples and X-ray computed tomography (CT) of cores will be discussed. Finally, reaction …

The Influence of Equilibrium Reactions on the Kinetics of Calcite Dissolution in Lactic Acid Solutions
… largest contribution to overall resistance. A coreflood experiment was also performed to observe and confirm the wormholing tendencies of lactic acid in calcite. Lactic acid formed a single dominant, minimally-branched wormhole through the core.

Evaluation of Low Saline “Smart Water” Enhanced Oil Recovery in Light Oil Reservoirs
… was varied from 500-50,000 PPM during secondary coreflood to first determine the optimum salinity, which was later used in the tertiary recovery stage. By reducing brine salinity from 5,000 PPM to 1,500 PPM, oil recovery increased in the secondary stage and decreased upon reduction to 500 PPM, …

Development of a framework for scaling surfactant enhanced CO₂ flooding from laboratory scale to field implementation
… and verified through practical laboratory coreflood experiments and numerical simulation. Design of experiments was used to generate an appropriate sample space for the dimensionless groups from which a model that is capable of predicting oil recovery and pressure difference is developed. …

Non-thermal Recovery of Heavy oil and Oil Sands Using Nanoparticle
Heavy oils and oil sand resources are considered the largest portion of known energy resources, comprising 70% of total resources. Still, there is potential to increase oil production from these resources to fulfill future global energy needs. There have long been serious critiques of the methods …
