“…The Rumaitha Field in Abu Dhabi was the first pilot miscible CO 2 injection implemented in the region [25][26][27][28]. The second pilot CO 2 -EOR project has been implemented in Minagish Oolite Reservoir in west Kuwait [29]. The third project has been implemented in Field A located in the Harwell Cluster in southern Oman in which the field's AG mixture (CH 4 enriched with light and heavy hydrocarbon fractions found in natural gas as well as considerable amounts of sour gases (3-5 mol % H 2 S and 10-25 mol % CO 2 )) is used for reinjection [30,31].…”

“…The presence of permeability heterogeneity would also make considerable contribution towards initiating and development of viscous fingering [41]. A high permeability layer would present a preferential flow path for the fingering of the injected gas causing early gas breakthrough and a low overall oil recovery factor [28,29,49]. [40].…”

Enhanced Oil Recovery - Selected Topics

Miscible gas injection (MGI) is an effective enhanced oil recovery (EOR) method used worldwide often for light oil recovery. In the petroleum industry, many MGI processes typically involve injection of an associated gas (AG) mixture or CO2, which have both been recognised as excellent candidates for such processes. The initial part of this chapter provides a broad introduction and background to the EOR techniques used worldwide as well as those implemented in Oman oil fields and briefly discusses their critical importance. Oman is one of the most active countries in terms of successful MGI processes in the Middle East, hence the emphasis given in this chapter to such projects in this country. The second part covers the technical details of the MGI process and the potential problems and challenges associated with it, while the third part focuses mainly on the common techniques used to control gas mobility during gas flooding including MGI. The impediments and challenges for wider application of the mobility control techniques are also covered. The last section presents a sample feasibility evaluation for a real oil field around the implementation of mobility control techniques for an MGI process.

“…In order to improve the extraction of heavy crude oil, a large number of scientists are engaged in the research of heavy crude oil extraction technology. Enhanced oil recovery (EOR) technology enhances the flow rate of crude oil by reducing the viscosity of crude oil and is widely used in the extraction of heavy crude oil. − There are three major types of EOR: miscible displacement, chemical flooding, and thermal recovery. Geologically, application of different oil recovery technologies is mainly affected by the petroleum composition and rock formation structure of each oil field .…”

Adsorption of oil droplets on different hydrophilic and hydrophobic silica surfaces was studied by molecular dynamics simulations. The surfaces included fully hydrophilic, 50% hydrophobic, and fully hydrophobic silica, and the oil droplet belongs to a heavy oil drop containing asphaltenes and resins. The simulated results showed that the oil droplet is easier to adsorb on the fully hydrophobic system, and the oil phase moves faster than that on the other silica surface. After adsorption of the oil drop finished, the asphaltene and resin molecules on different surfaces showed different aggregated structure. On the fully hydrophilic surface, the asphaltene and resin molecules aggregate through a face-to-face stacking interaction, and they adsorbed vertically on the silica surface. This is attributed to formation of hydrogen bonding between the model molecules (asphaltenes and resins) and the silica surface. This result indicates that the hydrophilic surface has a stronger interaction with the asphaltenes and resins than the other surfaces. The calculated free energy of adsorption of the model molecules on different surfaces further proves that the fully hydrophilic surface has a stronger adsorption capacity to heavy oil drop.
