Establishing scale inhibitor retention mechanisms in pure adsorption and coupled adsorption/precipitation treatments
… and OMTHP (an hexa-phosphonate) using sand, kaolinite and siderite as the mineral phase. Adsorption experiments were carried out at a range of adsorbent mass/ fluid volume ratios (m/V), since this indicates whether we are in the purely adsorbing or in the coupled …

Force Chain Detection in Unconsolidated Sands
… to simulate the force chain network of the sand pack and predict its behavior under further stress loading. The model will allow to extract the statistics and the distribution of the stress across the calculated volume and find the regions where the probability of higher stresses within the …

Experimental and Simulation Study of Relative Permeabilities in Heavy Oil/Water/Gas Systems
… core composed of cleaned Athabasca sand matrix and relative permeabilities of the involved phases were determined. Athabasca bitumen was used as the oil phase and distilled water and nitrogen were used as the water and gas phases respectively. A vertical sand-pack core-holder of 1.5 …

Experimental Simualtion Of Hot Fluid Injection Process for In-reservoir Upgrading
… vacuum residue (AVR) using dispersed hydrogen in sand pack media has been completed and extensively tested in this work. The deposition of the catalyst particles on the surface of the porous medium was studied and the amount of metal inside the reactor quantified. The results for catalytic …

Non-thermal Recovery of Heavy oil and Oil Sands Using Nanoparticle
Heavy oils and oil sand resources are considered the largest portion of known energy resources, comprising 70% of total resources. Still, there is potential to increase oil production from these resources to fulfill future global energy needs. There have long been serious critiques of the methods …

Evaluation of Propane-Butane Mixtures as Solvent in ES-SAGD
… of nearly immobile bitumen from the deeper oil-sand formation. In this method, two parallel horizontal wells are drilled near the reservoir bottom, one about 5 m higher than the other. Steam injected through the upper well provides heat to the heavy oil to reduce its viscosity. The heated oil …

The Impact of Surface Modified Nanoparticles on the Performance of Polymer Solutions for Heavy Oil Recovery
… recovery tests in a Hele-Shaw cell and linear sand-packs. According to the observations in Hele-Shaw cell, the fingering patterns of XG and XG/1.0-2.0wt% of NPs were characterized by the formation of branched structures (at earlier growth stage) which by merging and coalescing formed stable …

Ultrasound Testing System for the Detecting of the Shape and Growth of a Vapor Chamber in the VAPEX Process
… air balloons buried in a water- or oil-saturated sand pack. The ultrasound receivers were placed on the physical model to detect the acoustic signals from the transducers. A MatlabTM based program was developed to do the signal processing using wavelet signal transform technique to extract the …

Injection Impairment by Suspended Solids: Well Models, Filtration Parameters, and Models’ Validation with 3-D Injection Experiments
… horizontal wells have been validated with 3-D sand pack tests. Filtration coefficient and damage factor are required for modeling internal formation plugging from suspended solids particles during water injection. This is obtained experimentally and depends on flow velocity, particle slurry …

Geophysical properties of carbon monoxide when used as an enhanced oil recovery agent
… These tests were carried out with artificial sand packs in order to control the amount of swelling clays present in each sample being tested. The samples were outfitted with acoustic transducers and were ported at both ends to allow for fluid flow in and out of the sample. Measurements were …

Dynamic and Static CO2 Mass Transfer Processes in Bulk Heavy Oil and Heavy Oil Saturated Porous Media
… diffusion coefficient in porous media. A hollow sand pack model was improvised to simulate a well-bore area, when CO2 and oil are in contact. In this model, CO2 is in the inner space, and the heavy oil saturated sand is placed in the outer space of the model. Six experiments in pressure range of …

Experimental analysis of natural gas transport: using nanoporous ceramic cores as mimetic model for low permeability reservoirs.
… Low permeability reservoirs, such as tight sands, coalbed methane and shale gas formations, present significant challenges for natural gas extraction due to their complex pore structures and limited flow characteristics. Traditional methods for studying these reservoirs, like sand pack …

Utilization of Carbonated Water Injection (CWI) as a Means of Improved Oil Recovery in Light Oil Systems: Pore-Scale Mechanisms and Recovery Evaluation
… called threshold CO2 solubility, χth. Results of sand-pack CWI flooding tests revealed that the recovery factor (RF) substantially increases up to a pressure of P = 5.6 MPa followed by slow growth until the pressure reaches P = 10.3 MPa. The same turning point of about P = 5.6 MPa was also …

Multi-scale Analysis of Methane Gas Hydrate Formation and Dissociation via Point Source Thermal Stimulation and Carbon Dioxide Exchange
… applied to a 50% hydrate saturated quartz sand pack. The amount of carbon dioxide stored in the hydrate phased was greatest for the low injection-high heating condition sequestering 69 moles, and lowest for the high injection- low heating condition sequestering 13 moles. The gas exchange is …
