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,

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 ...

Low salinity waterflooding for Enhanced Oil Recovery - stochastic model calibration and uncertainty quantification [PDF]

open access: yes, 2015
We focus on key aspects related to the quantification of the uncertainty associated with modeling of Enhanced Oil Recovery (EOR) through Low Salinity (LS) water injection in a reservoir.

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.

A New Mathematical Model for Flow and Heat Transfer of Dual-String Steam Injection in SAGD

open access: yesGeofluids
Uneven steam distribution along horizontal wellbores, particularly the disparity between the heel and toe, poses a significant challenge in steam injection for heavy oil recovery.

Experimental Investigation of Oil Recovery from Tight Sandstone Oil Reservoirs by Pressure Depletion

open access: yesEnergies, 2018
Oil production by natural energy of the reservoir is usually the first choice for oil reservoir development. Conversely, to effectively develop tight oil reservoir is challenging due to its ultra-low formation permeability.
