Implementation of Chemical Flooding Module into the General Purpose Adaptive Simulator
… with special properties calculated in a chemical module. This chemical module takes into account the flux across each grid interface, the phase saturations, phase densities and the upstream locations for each gridblock and uses the one-point upstream weighting numerical method. This is a …

A Study of Residual Oil Saturation in Heterogeneous Sandstone Experiments
… porous media is studied. A compositional chemical flooding simulator (UTCHEM) using high resolution numerical method was used to simulate the previous coreflooding experiments as well as to study the sensitivity of different parameters -heterogeneity, capillary pressure, mobility ratio, …

INTERFACIAL TENSION MEASUREMENT BY SESSILE DROP USING DIGITAL IMAGE PROCESSING
… This condition can be achieved by surfactant or chemical flooding but requires accurate modeling of reservoir conditions and determination of interfacial tensions, IFTs. The spinning drop technique is very popular but the sessile drop method offers the advantage that it is a static system. Most …

Vectorization and microtasking of UTCHEM on the CRAY X-MP
UTCHEM, a chemical flooding simulator, was optimized/vectorized and microtasked on the CRAY X-MP. Details of implementation of these methods on UTCHEM and possible extension to other reservoir simulators were discussed. Speedup factors of up to 40 by a combination of vectorization and microtasking …

Laboratory Investigation of Polymer-flooding, ASP-flooding, and Foam-flooding in Heavy Oil System
… because heat losses will be too severe. Water flooding is an alternative but it can only achieve a very low oil recovery due to severe viscous fingering. Hence, research into other non-thermal recovery methods is necessary. This thesis presents a laboratory-scale investigation of heavy oil …

Optimization of chemical enhanced oil recovery methods for naturally fractured carbonate reservoirs
… especially if they are naturally fractured. Waterflooding is inefficient because water flows through the highly permeable fractures and bypasses the rock matrix, where most of the oil is stored. Mixed-wettability, low matrix permeability, and large heterogeneities also make secondary oil recovery …

Application of surfactant-polymer enhanced oil recovery in a high- salinity, high-temperature carbonate reservoir
… enhanced oil recovery (EOR) methods, such as chemical flooding, grows. A widely used type of chemical EOR is surfactant-polymer flooding (SP). In SP flooding, a surfactant reduces the interfacial tension between oil and water to ultra low values, allowing residual oil to be mobilized and …

Performance Evaluation of ionic Liquids in Enhanced Oil Recovery Using Numerical Simulation
… taken a prominent role in resource management. Chemical flooding has proved to be one of the most efficient EOR techniques. This study investigated the potential of employing Ionic Liquids (ILs) as alternative chemical agents for improving oil recovery. There is very little attention paid to …

Investigating the effect of perforation diameter and carbon dioxide bubble size distribution on heavy oil recovery
… heavy oil-Enhanced Oil Recovery (EOR) process is chemical flooding. However, the formation of brine with high salinity and divalent ions leads to process inefficiencies. In this study, experimental techniques have been developed to examine the effect of perforation diameter and CO2 bubble size …

The Impact of Surface Modified Nanoparticles on the Performance of Polymer Solutions for Heavy Oil Recovery
The use of polymer flooding as an enhanced oil recovery (EOR) method to achieve a more uniform volumetric sweep of the reservoir has increased over the past ten years. However, chemical, thermal and mechanical degradation of the polymers reduce their viscosity, which affects their performance. …
