Summary In this article we present results of dynamic and static precipitation tests to investigate the likelihood asphaltene deposition problems in southeast Saskatchewan's Weyburn reservoir. Tests were conducted at reservoir temperature pressure conditions. The effect on flocculation/precipitation operating pressure, CO2 concentration, gas contaminants CO2, presence formation brine was investigated for three different oil samples using pressure/volume/temperature (PVT) tests. extent also...
Microbial exopolysaccharides secreted by microorganisms during metabolic processes have been widely used in biotechnology because of their environmentally friendly and renewable nature. This study evaluates the potential a novel microbial exopolysaccharide, diutan gum, which is produced Sphingomonas species, for enhanced heavy oil recovery at high temperature salinity. In addition, two conventional polymers [xanthan gum partially hydrolyzed polyacrylamide (HPAM)] exploitation are compared...
Experiments have been conducted to determine the viscosities of water-in-oil (W/O) emulsions in porous media. W/O were first prepared for different volume fractions dispersed phase and then characterized their properties rheological parameters including flow index consistency constant. All with between 6.78% 33.48% found behave as non-Newtonian shear-thinning fluids at fairly high viscosities. The measured during emulsion three types sandpacks. A correlation media was developed by performing...
The displacement efficiency of welan gum on enhanced heavy oil recovery has been investigated by comparing that xanthan which is commonly used for polymer flooding, and it found the biopolymer higher (>7.0 % at normal permeability) than gum. In-depth rheological investigations show both storage modulus loss solution are those solutions same concentration, temperature salinity. mainly caused its stronger ability to form aggregates. Although molecular weight lower gum, aggregates molecules...
Property tests were first conducted to characterize the subject oil-in-water emulsions having three different interfacial tensions and droplet sizes in terms of their stability, size distribution, rheological behaviors. Then sandpack flow experiments conducted, permeability reduction used quantify plugging performance each flowing at rates through sandpacks. The results showed that effect an emulsion was primarily due special behaviors droplets porous media; is, bulk viscosity contributed...
Abstract For heavy oil reservoirs (with viscosities ranging from 1,000 to more than 10,000 mPa-s), primary production and waterflood can only recover 5 10% initial oil-in-place (IOIP) due the unfavourable mobility ratio of water phase phase. Heavy oils usually have a relatively high content organic acids, which be neutralized by alkalis form in-situ surfactants. With assistance these surfactants, an oil-in-water emulsion with much lower viscosity generated. In this way, is entrained in...
The effect of the surfactant, NaOH, and polymer interactions between them on heavy oil/water interface are unveiled by studying dynamic interfacial tension (IFT), minimal transient IFT, total organic carbon (TOC) analyzing phenomenon during measurement IFT oil/different alkaline systems, including (A), alkaline–surfactant (AS), alkaline–polymer (AP), alkaline–surfactant–polymer (ASP). results show that there exists a minimum IFT. There is an optimal composition to achieve with varying NaOH...
Compound oxides (NiFeO and CoFeO) were obtained by calcining layered double hydroxide (LDH) precursors prepared microwave-hydrothermal method. The structure of LDHs compound was characterized X-ray diffraction (XRD). thermal behavior flammability polypropylene (PP) composites containing different types investigated thermogravimetric analysis (TGA), limiting oxygen index (LOI), cone calorimeter. Fire performance characterization has demonstrated that both NiFeO CoFeO can significantly...
Abstract A transverse pressure pulse decay (TPPD) method is presented to measure permeability of tight reservoir cores in a cell with finite volume. Given appropriate assumptions, mathematical model based on the specially designed experiment formulated, and its general solution proposed. Early‐time late‐time techniques are further for convenient postprocessing applications experimental data. Meanwhile, sensitivity analysis TPPD given. It found that good principle can be obtained by adjusting...
Amide- and alkyl-modified nanosilicas (AANPs) were synthesized introduced into Xanthan gum (XG) solution, aiming to improve the temperature/salt tolerance oil recovery. The rheological behaviors of XG/AANP hybrid dispersions systematically studied at different concentrations, temperatures inorganic salts. At high temperature (75 °C) salinity (10,000 mg⋅L−1 NaCl), AANPs increase apparent viscosity dynamic modulus XG dispersion exhibits elastic-dominant properties. most effective...
