The purpose of this study was to investigate the hydrate formation and dissociation with CO2 flowing through cooled porous media at different flow rates, pressures, temperatures, directions. saturation quantified using mean intensity water. experimental results showed that block appeared frequently, it could be avoided by stopping flooding early. Hydrate formed rapidly as temperature set 274.15 or 275.15 K, but delayed when 276.15 K. rate an important parameter for formation; a too high low...
CO2 flooding is one of the most popular secondary or tertiary recoveries for oil production. It also significant studying mechanisms two-phase and multiphase flow in porous media. In this study, an experimental study was carried out by using magnetic resonance imaging technique to examine detailed effects pressure rates on CO2/decane a bead-pack The displacing processes were conducted under various pressures region near minimum miscibility (the system tuned from immiscible miscible as...
We provide a feasible method to estimate the minimum miscibility pressure (MMP) of CO2/n-decane system by using high spatial resolution magnetic resonance imaging (MRI). During measurement, signal intensity n-decane with CO2 dissolved is measured. The MRI images show that decreases zero and interface disappears at MMP. A good exponential growth relation found between system. relationship MMP temperature established quantitatively, which in close agreement previous studies. Moreover it could...
Fractured reservoirs form a large percentage of the world's hydrocarbon reserves. However, in spite their wide occurrence and huge reserves, oil recovery from most these is extremely low. CO2 flooding has proven to be an efficient Enhanced Oil Recovery (EOR) method. This article addresses use MRI technique follow removal process oil, water, supercritical multiphase flow fractured artificial consolidated sandstone core with permeability heterogeneity at typical reservoir temperature pressure...
Carbon dioxide tertiary or secondary oil recovery becomes increasingly significant to the petroleum industry. CO2 flooding can not only enhance improve clearly but also considerably reduce greenhouse gas emission. After was injected into an reservoir, it contacted reservoir and, consequently, changed equilibrium conditions and fluid properties, which may lead precipitation of organic solids, primarily asphaltenes. In this case, bulk porosity reduces obviously because asphaltene deposition,...
The present study provides some important thermodynamic and kinetic data for the CO2 hydrate formation in flow system. Images were obtained dynamically using Magnetic resonance imaging (MRI) system, with a fast spin-echo multi-slice scan sequence (FSEMS). dissociation rate was quantified MRI mean intensity of liquid water. saturation residual water, gas during also data. highest 58% first process, 26% second process this investigation.
Measurement of CO2/water two phase fluids flow in the porous media under sequestration conditions by Magnetic Resonance Imaging (MRI) technique was studied this paper. The formed from a packed bed glass beads. A spin echo sequence used to measure distribution CO2 and water after injected into containing water. displacement front different with beds. For experiments BZ-02 BZ-2, three stages were obtained. channeling or fingering phenomena obviously found. Also breakthrough time BZ-2. final...
CO2 miscible flooding is one of main technologies in both the secondary and tertiary floods for Enhanced Oil Recovery (EOR). In addition, it also an important alternative a geological storage. recent twenty years, fundamental research visualized CO2-EOR has been launched by using mainly Magnetic Resonance Imaging (MRI). this study, we simulated model Eclipse reservoir simulation software based on MRI coreflood test. We modified numerical changing parameters to improve flood results.
It is not uncommon for underground water supply or heating pipelines to break and leak, but such events can cause serious inconvenience the lives of residents. The accurate timely detection leak locations primary objective in solving pipeline rupture issues. Based on direct current (DC) resistivity method, which provides a stable signal, convenient interpretation, strong anti-interference ability, we adopted pole-pole device form DC potential method detect leaks high-resistivity pipelines. A...
CO2 flooding is the most popular recovery for oil production. It significant to study mechanism of multiphase flow in porous media. In this study, experimental studies are carried out by using MRI technique examine detailed effects miscibility and forces on CO2/n-decane medium narrow channel. The displacing processes conducted at various pressures temperatures. revolution distribution decane characteristic two phase investigated analyzed. Difference between series tests was specified.

SUMMARY Squirt flow plays an essential role in elastic modulus dispersion and attenuation for fluid-saturated cracked porous rocks. The Mavko–Jizba model relevant modified models can describe the squirt well based on related moduli, such as dry/drained bulk modulus. However, when these moduli are challenging to attain, it is impossible squirt-flow-related attenuations with models. On other hand, effective medium theory (EMT) estimate but cannot predict undrained/relaxed partially relaxed...
