Pore-scale simulation of wettability and interfacial tension effects on flooding process for enhanced oil recovery [PDF]

open access: yes, 2017
For enhanced oil recovery (EOR) applications, the oil/water flow characteristics during the flooding process was numerically investigated with the volume-of-fluid method at the pore scale.

Using multiphase fluid flow modeling and time-lapse electromagnetics to improve 4D monitoring of CO 2 in an EOR reservoir [PDF]

open access: yes, 2018
Understanding the changes in the saturation within a reservoir undergoing enhanced oil recovery (EOR) is crucial to optimizing production. We debut a novel, multiphase fluid flow modelling code, TOGA, to assist in modeling gas, oil, and water phases ...

Study on Pulse Characteristic of Produced Crude Composition in CO2 Flooding Pilot Test

open access: yesGeofluids, 2018
It has been observed in many laboratory tests that the carbon number of the maximum concentration components (CNMCC) of produced oil varies monotonically with CO2 injection volume at the core scale. However, in CO2 flooding pilot test at the field scale,

Understanding the Impact of Open-Framework Conglomerates on Water-Oil Displacements: Victor Interval of the Ivishak Reservoir, Prudhoe Bay Field, Alaska [PDF]

open access: yes, 2014
The Victor Unit of the Ivishak Formation in the Prudhoe Bay Oilfield is characterized by high net-to-gross fluvial sandstones and conglomerates. The highest permeability is found within sets of cross-strata of open-framework conglomerate (OFC).

A model study of enhanced oil recovery by flooding with aqueous surfactant solution and comparison with theory [PDF]

open access: yes, 2015
With the aim of elucidating the details of enhanced oil recovery by surfactant solution flooding, we have determined the detailed behavior of model systems consisting of a packed column of calcium carbonate particles as the porous rock, n-decane as the ...

Comparative Analysis of CO2, N2, and Gas Mixture Injection on Asphaltene Deposition Pressure in Reservoir Conditions

open access: yesEnergies, 2018
CO2 and N2 injection is an effective enhanced oil recovery technology in the oilfield especially for low-permeability and extra low-permeability reservoirs. However, these processes can induce an asphaltene deposition during oil production.

Experimental study of flow friction behavior in coiled tubing

open access: yesEnergy Reports, 2022
Coiled tubing (CT) technology has been widely applied in well cleanouts, drilling plug, and shale oil and gas fracturing. Fluid flow in CT produce a more significant flow friction pressure loss because of the long length and small tubing diameter coiled ...

Preface: The Second Generation of Second Amendment Law & Policy [PDF]

open access: yes, 2010
Over 70% of China’s domestic oil production is obtained from nine giant oilfields. Understanding the behaviour of these fields is essential to both domestic oil production and future Chinese oil imports.

An improved viscosity model for CO2-crude system

open access: yesPetroleum Exploration and Development, 2014
The existing viscosity models, including LBC (Lohrenz-Bray-Clark) Model, CS (Pedersen) Model and PR (based on PR Equation of State) Model, could not take into account accuracy, theory strictness and calculation convenience simultaneously.

Experimental Study on Enhanced Oil Recovery of PPG/ASP Heterogeneous System after Polymer Flooding

open access: yesGels, 2023
Following the application of polymer flooding in Daqing Oilfield, the heterogeneity between different layers has intensified, resulting in the formation of more favorable seepage channels and cross-flow of displacement fluids.
