A streamline model application for the waterflood performance of NZ-OF-HRL carbonate reservoir
… reservoir had produced only 3.07 per cent of the oil in place, mainly by internal gas drive, when the pressure had declined from the original pressure of 4,781 psig to 4,009 psig to 8,750 feet. As a result of such rapid change in pressure and due to the fact that energy contribution from the …

Effect of Temperature on Performance of Vapex Process for Heavy Oil
Incorporating some heat injection along with the solvent injection appears to be the most viable option for improving the oil drainage rate of Vapex (Vapor Extraction) in extra-heavy oil formations. This study was aimed at quantifying the upper limit of oil rates achievable with heated solvent …

Surfactants and enhanced oil recovery
… view to their potential usefulness for enhanced oil recovery (EOR) application. Ethoxylated phenols and their sulphonated derivatives were given especially high priority. The surfactants were well-characterised in order to understand their EOR potential. High pressure liquid chromatography, mass …

Numerical simulation and optimisation of polymer flooding in a heterogenous reservoir : constrained versus unconstrained optimisation
Polymer flooding offers the potential to recover more oil from reservoirs but requires significant investments which necessitate a robust analysis of economic upsides and downsides. Key uncertainties in designing a polymer flood are often reservoir geology and polymer degradation. The objective of …

Estudo paramétrico do processo de extração com solvente (VAPEX) como método de recuperação de óleo pesado
… is still a large amount of natural resources in heavy oil reservoirs which can be explored using new methods. The world estimate of resources as heavy oil and bitumen may be 6 trillion barrels of oil in place. However, this enormous amount of hydrocarbon resources which are in these reservoirs …

Fluctuations in resistivity in the Tuscaloosa Marine Shale, southwest Mississippi and southeast Louisiana
The Tuscaloosa Marine Shale in southwest Mississippi and Southeast Louisiana's Florida Parishes has become an unconventional target for the exploration and production of oil. Spurred by early estimates of over 7 billion barrels of oil in place, the target region for this production is the basal …

Molecular Dynamics Study of Nano-confinement Effect on Hydrocarbons Fluid Phase Behavior and Composition in Organic Shale
The depletion of conventional oil reservoirs forced companies and consequently researchers to pursue alternatives such as resources that in the past were considered not economically viable, in consequence of the high depth, low porosity and permeability of the play zone. The exploration challenges …

Factors impacting the transport and enhanced oil recovery potential of polymeric nanogel in sandstone
"Enhanced oil recovery (EOR) using nanometer-sized particles has drawn great attention in the oil industry because of their various advantages brought by size. However, their applications on a field scale are very limited, especially for deformable nanoparticles. The objective of this research is …

Effects of Sedimentologic and Stratigraphic Heterogeneity on Production in Carbonate Reservoirs: An Integrated Outcrop, Synthetic Geologic Modeling, and Flow Simulation Study
… the many scales and types of heterogeneity in carbonate reservoirs; however, systematic quantitative assessment of the impact of this range of geological variations on production from carbonate reservoirs is rare. To explore and quantify the impact of geologic heterogeneity of hydrocarbon …

The potential use of bio-ultracarbofluids in a standard diesel engine
The replacement of diesel fuel by ultra-carbofluids was perceived to offer the potential to decrease the emissions of environmental pollutants such as carbon dioxide, carbon monoxide, hydrocarbons (HC's) and smoke. Such ultracarbofluids consist of a suspension of coal in fuel oil and water …

Application of surfactant-polymer enhanced oil recovery in a high- salinity, high-temperature carbonate reservoir
As the world energy demand increases, and the discovery of new conventional reservoirs diminishes, the need of using 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 …

NMR Studies of Enhanced Oil Recovery Core Floods and Core Analysis Protocols
With conventional oil reserves in decline, energy companies are increasingly turning to enhanced oil recovery (EOR) processes to extend the productive life of oilfield wells. Laboratory-scale core floods, in which one fluid displaces another from the pore space of a rock core, are widely used in …

Petrographic and petrophysical characterization of the Eagle Ford Shale in La Salle and Gonzales counties, Gulf Coast Region, Texas
The Eagle Ford Shale is an organic-rich marine carbonate-dominated mudrock located in the Gulf Coast Region, Texas. This mudrock was deposited during the Late Cretaceous and is composed of two main members: the lower and the upper Eagle Ford, which are associated to marine transgression and …

An Improved Vapour Solvent Injection Technique for Enhanced Heavy Oil Recovery
There are tremendous heavy oil and bitumen resources in Canada, and most of them are located in the Western Canadian Sedimentary Basin. Thermal-based recovery techniques, such as steam flooding, cyclic steam stimulation (CSS), and steam-assisted gravity drainage (SAGD), are effective and have been …

Rheology and Flow Behaviour of Non-Newtonian, Polymeric Fluids in Capillaric and Porous Media: Aspects Related to Polymer Flooding for Enchanced Recovery of Heavy Oil
Heavy oil reservoirs under consideration for polymer flooding typically contain greater than 85% of the original oil in place (OOIP) after primary recovery and waterflooding. Many of these fields are operated at high producing water/oil ratios (WORs) only marginally above their economic limit due …

Performance Evaluation of an Enhanced Cyclic Solvent Process (ECSP) for Thin Heavy Oil Reservoirs
Canada’s energy future depends on heavy oil resources, which are mainly located in Western Canada, i.e., Saskatchewan and Alberta, and account for almost half of the total world heavy oil reserves. At present, only 8-9% of the original oil in place (OOIP) can be recovered in such heavy oil …

Digital Rock: Understanding the mechanism of Enhanced Oil Recovery (EOR) Core Floods
Oil companies aim to increase their return on investment by extending the productive life of their existing oilfields. For that purpose, a better understanding of the physical phenomena which occur during waterflooding and enhanced oil recovery (EOR) is needed to optimise the oil recovery. In this …

Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,
In continuous CO2 secondary flooding, severe viscous fingering and early CO2 breakthrough (BT) occur due to an unfavourable mobility contrast between the injected CO2 and the crude oil. The oil recovery is limited after CO2 BT, which is attributed to the gas channeling problem. In continuous CO2 …

Experimental and Modelign of Foam Physics in Porous Media
Foam is a dispersion of gas in a liquid, where the liquid is continuous and part of the gas is made discontinuous by thin liquid films (lamellae) (Hirasaki and Lawson, 1985). Foam promises to substantially improve reservoir sweep in gas-injection enhanced oil recovery (EOR) projects. Predictive …
