A modified pressure decay method has been designed and tested for more reliable measurements of molecular diffusion coefficients gases into liquids. Unlike the conventional method, experimental setup such that interface consequently dissolved gas concentration at are kept constant. This is accomplished by continuously injecting required amount cap from a secondary supply cell to maintain constant gas−liquid interface. The measured in cell. advantage new technique that, assuming coefficient...
AimsTo test the hypothesis that near-infrared spectroscopy (NIRS) combined with intravascular ultrasound (IVUS) would provide novel information of human coronary plaque characterization.
Abstract This paper examines the effects of in situ formation a non-aqueous foam on flow oil-gas mixtures porous media. A laboratory technique to investigate role foamy-oil behaviour solution gas drive is described and experimental verification foams under condition presented. The results show that retards continuous phase dramatically increases apparent trapped saturation. provides natural pressure maintenance mechanism leads recovery much higher fraction Original oil place drive....
Abstract The saturation pressure and solubility of propane in Athabasca bitumen, as well the liquid phase densities viscosities, were measured for temperatures from 10 to 50 °C. Equilibration proved challenging this fluid mixture required some experimental modifications that are discussed. Only liquid-vapour regions observed at contents below 20 wt%. A second appeared have formed higher contents. pressures, where only a single dense formed, ranged 600 1,600 kPa these fitted with modification...
Abstract Laboratory tests were carried out to evaluate a CO2 huff-n-puff well stimulation process in Lloydminster heavy oil reservoir. Two series of phase behaviour measurements done on the reconstituted oil, each pressurization-then-liberation cycle. The first was performed using as carbonating gas. Some swelling occurred, and large viscosity reduction observed. retained preferentially CH4 during liberation and, consequently, reduced viscosities maintained down low pressures. second 1:3...
Appropriate techniques have to be developed for improving heavy oil recovery from thin reservoirs in western Canada, where thermal methods suffer heat loss overburden/underburden and vapor extraction (VAPEX) is not effective because of the lack efficient gravity drainage. Considering this, a hydrocarbon gas injection process huff-n-puff mode, i.e., traditional hydrocarbon-based cyclic solvent (CSP), has been tested evaluate its applicability such reservoirs. In first part this study,...
Expanding solvent steam assisted gravity drainage (ES-SAGD) is a hybrid steam–solvent oil recovery process that can be used to extract from heavy and bitumen reservoirs. It variation of the SAGD in which only used. In ES-SAGD, mobilization highly viscous enhanced through combination heat mass transfer processes, results significantly reduced volumes water natural gas needed generate injected steam, making ES-SAGD more energy efficient environmentally sustainable relative SAGD. Both use same...
Polymer solutions are designed to develop a favorable mobility ratio between the injected polymer solution and oil–water bank being displaced by polymer. Subsequently, more uniform volumetric sweep of reservoir is produced. Chemical mechanical degradation solutions, on other hand, reduce their viscosity which significantly affects performance. The primary objective this study investigate effect surface modification silica nanoparticles (NPs) effective partially hydrolyzed polyacrylamide...
Abstract Vapour extraction (VAPEX) is a potentially economic process for the recovery of heavy oil and bitumen in Canadian reservoirs, as all injected solvent effectively delivered to zone interest. In addition, has potential sequester greenhouse gases, capable situ upgrading oil. The research described this paper was undertaken identify main processes governing interfacial mass transfer into bitumen. A number experiments were carried out Hele-Shaw cell, results incorporated predictive...
Summary Interest in the vapor-extraction (Vapex) process for heavy-oil and bitumen recovery has grown considerably as a viable environmentally friendly alternative to currently used thermal methods. The potential success of Vapex is even more attractive some scenarios that preclude presence an overlying gas cap and/or bottomwater aquifer, thin pay zones, low conductivity, high water saturation, unacceptable heat losses overburden underbur-den formations are limitations with techniques, which...
Abstract Although a number of studies have reported significant effects temperature on relative permeabilities no consensus has emerged the generality such nor possible mechanisms causing effects. Some recent found permeability to be independent and suggested that most can attributed artifacts unsteady-state technique. The objective this study was critically examine use technique for measuring in heavy oil systems experimentally determine effect curves clean silica sand/heavy crude...
Abstract The solubility of pure carbon dioxide in Athabasca bitumen was measured and compared with the literature data. Multiple liquid phases were observed at contents above approximately 12 wt%. A correlation based on Henry's law found to fit saturation pressures below pressure propane bitumen, as well phase densities viscosities, for three ternary mixtures temperatures from 10 25 °C. Two (carbon dioxide-rich bitumen-rich) 13 wt% 19 propane. Only vapour-liquid regions other two (13.5 11.0...
Abstract The proposed in situ catalytic upgrading of heavy oil to achieve an environmentally sustainable method for recovery requires the placement nanodispersed catalyst particles deep into formation where it can accelerate high‐temperature reactions. In continuation previous work [Zamani et al., Energy Fuels 24, 4980‐4988 (2010)], this paper presents results several new experiments carried out examine effects other parameters, including connate brine salinity, absolute permeability,...
