Despite the positive aspects of low salinity water (LSW), this technique is relatively expensive and unavailable in some countries. Furthermore, potential problems associated with LSW such as scale precipitation in carbonate reservoirs and fine migration in sandstone reservoirs raise concerns. Chelating agents have the ability to chelate metal ions...

Chelating agents have the ability to capture metal ions from brine. This process helps to decrease the salinity of injected water and prevents the formation of scale precipitation in reservoirs. When chelating agents are diluted in seawater (SW), they exhibit similar properties to low-salinity water (LSW) and can be effectively used as an alternati...

This study used the diethylene triamine pentaacetic acid (DTPA)-seawater (SW) system to modify the sandstone rock wettability and enhance oil recovery. The investigation involved conducting wettability measurement, Zeta potential measurement, and spontaneous imbibition experiment. The introduction of 5% DTPA-SW solution resulted in a significant de...

In a previous work, we developed shape memory polyurethane lost circulation materials (SMPU LCMs) programed to recover at wellbore temperature and plug fractures. Further testing and characterization of SMPU LCMs under various conditions and in the presence of different drilling fluid additives promote their field applicability. In this work, SMPU...

Anion exclusion is an important phenomenon in agricultural, environmental and engineering fields which still needs suitable quantitative models. In this work, a novel model is proposed which considers the porous media as parallel capillaries with negatively charged walls that cause total anion exclusion at a distance from the walls. By defining the...

Wellbore strengthening is a technique for increasing formation fracture pressure and widening the mud window. In this study, smart wellbore strengthening materials (WSMs) built on shape memory polyurethane (SMPU) are introduced. SMPU WSMs are programmed to release pre-determined recovery stress once unfold at predetermined temperature. The molecula...

Drilling fluid loss is a major problem with serious economic and environmental consequences. The use of traditional lost circulation materials (LCMs) to seal wide fractures increases the risk of bit nozzle plugging. In this work, smart LCMs based on shape memory polyurethane (SMPU) are proposed for the first time. SMPU can be programmed to recover...

In this study, possibility of geological storage of CO2 into an Iranian hydrocarbon reservoir is investigated as a method of enhanced oil recovery (EOR). For this purpose, a stainless steel sand packed model, containing rock and brine, was used to simulate the reservoir condition and CO2 injection. Subsequently, CO2–rock–brine interactions (dissolu...

Compositional simulators are of great importance to model core flow experiments and enhanced oil recovery processes. In the present study, a semi-implicit, three dimensional EoS-based formulation is developed for modeling and simulation of core-flooding process. The model treats three-phase flow in cylindrical coordinates with no need to use an ite...

Base gas replacement by a cheap gas is one of the approved methods to reduce the cost of investment in underground gas storage process. Maximizing the amount of replaceable base gas is an attractive issue. However, the amount of base gas replacement can be reduced due to some limiting factors. By changing the composition of the candidate base gas,...

In this work, the partitioning behavior of Doxorubicin, an antineoplastic drug, has been investigated in the polymer-salt aqueous two-phase systems (ATPSs), and the ability of three nanoparticles (NPs) including graphene oxide (GO), functionalized single, and multi-walled carbon nanotube (f-SWCNT and f-MWCNT) as additives for increasing the partiti...

Base gas is considered as an important factor in the storage operation as it remains permanently in the reservoir and maintains the reservoir pressure along the production cycle. Depending on the reservoir under consideration, base gas may occupy as little as 15% or as much as 75% of the total underground gas storage (UGS) reservoirs. Providing and...

One way to reduce the costs of investment in underground natural gas storage processes is to replace a portion of the base gas with a cheap gas. Optimizing the replacement amount of the base gas is one of the most attractive issues as mixing between the replaced base gas and the working gas and exceeding the injection pressure above the formation f...

In this research, the influence of effective parameters on ozone penetration in the soil contaminated with anthracin has been investigated. The soil was then contaminated with anthracin, a polycyclic aromatic hydrocarbon, after washing and moisture removal stored in a dark environment for one week in closed containers. The parameters studied are as...

Carbon dioxide is a greenhouse gas that has the most effect on the phenomenon of global warming. Saline aquifers have higher potential compared to other storage options to store carbon dioxide. Sandstone and carbonate aquifers have good reservoir characteristics and can be appropriate choices for CO2 storage. The modeling of the process has been pe...

Many laboratory results have proved potential of low salinity water injection (LSWI) for improving oil recovery in sandstone formation. Some one-dimensional models have been developed to describe the low salinity effect and possible driving mechanisms. The objective of this study is to develop two-dimensional model based on two different approaches...

Caprock integrity is a primary criterion for evaluating depleted oil and gas reservoirs for long-term safety of carbon dioxide geosequestration. The occurrence of capillary leakage is inevitable in caprock. This phenomenon occurs whenever the buoyancy pressure due to accumulated CO2 plumes dominates the capillary pressure of caprock, and thereby th...

Gas condensate reservoir fluids exhibit unique thermodynamic behavior which is considered as the controlling factor to develop these types of reservoirs. In the region between critical and cricondentherm temperature, two dew points are observed called the upper and lower dew pressures. In general, estimating the dew points are performed applying se...

Due to excessive production of carbon dioxide from fossil fuels, emissions of this greenhouse gas in the atmosphere is over 28 Giga tons annually. In the past centuries, the average concentration of carbon dioxide in the atmosphere was 280 ppm which has increased to 375 ppm after the Industrial Revolution. According to recent studies, increase in c...

Regression processes is done in order to access the improvement of the equation of state predictions. In fact, the regression parameters are tuned to get the best match between the EOS results and experimental data in fluid properties estimation. This study is done in two sections (experimental and simulation); to specify the effective parameters i...

The hydrocarbon plus fractions that comprise a significant portion of naturally occurring hydrocarbon fluids create major problems when determining the thermodynamic properties and the volumetric behavior of these fluids by equations of state. These problems arise due to the difficulty of properly characterizing the plus fractions (heavy ends). Pro...

In this work, a thermodynamic model based on statistical association fluid theory (SAFT) is developed to predict the phase behavior of mixtures containing asphaltene contents. The SAFT equation of state is a good candidate for closing that gap between statistical mechanic models and the classical models dominated by cubic equation of state. A robus...

Reservoir hydrocarbon fluids contain heavy paraffins that may form solid phase of wax at low temperatures. Formation of solid phases is highly unwanted in oil production assemblies, pipelines and in process equipments. A predictive technique is crucial to the solution of wax formation to alleviate this problem.The effect of different parameters to...
