Hydrothermal upgrading and adsorption of a water-soluble nickel-based catalyst precursor in a porous media of carbonate oil-saturated rock [PDF]

Scientific Reports
This study investigates the efficiency of a water-soluble nickel-based catalyst precursor in enhancing oil recovery through steam injection processes. Four filtration experiments were performed using a bulk formation model with initial oil saturation to ...

The numerical simulation study on the dynamic variation of residual oil with water drive velocity in water flooding reservoir

Frontiers in Energy Research, 2023
The results of core displacement experiments show that increasing the water drive velocity when it is bigger than the limit value can effectively reduce the residual oil saturation and improve the oil displacement efficiency under the same PV.

The effect of injection speed on the law of heavy oil initiation and seepage flow research [PDF]

E3S Web of Conferences, 2022
In order to make the heavy oil flow, the repulsion pressure gradient should be larger than the start-up pressure gradient. The results show that the smaller the injection speed is, the smaller the start pressure gradient is, and the subsequent seepage ...

Study of the Effect of Relative Permeability and Residual oil Saturation on Oil Recovery [PDF]

Linköping Electronic Conference Proceedings, 2015
Depletion of the production and the low recovery factor are major challenges faced in petroleum industry. The recovery factor and the lifetime of a well are strongly affected by the reservoir properties such as permeability, porosity, residual oil saturation and the water breakthrough time.

Influence of the pore space structure and wettability on residual gas saturation

Georesursy, 2020
A significant part of hydrocarbon deposits in Russia is in the late stage of development. The distribution of residual oil and gas reserves is determined by the properties of the holding rocks.

Evaluation of the Factors Influencing Residual Oil Evolution after Alkali/Surfactant/Polymer Flooding in Daqing Oilfield

Energies, 2022
The alkali/surfactant/polymer (ASP) flood has long been considered to reduce residual oil saturation significantly after waterflood. This paper provides an experimental investigation of the factors (permeability, pore structure, ASP formula, injection ...

An Investigation of Recovery Mechanisms for Oil Field Optimization by Three-Phase Core Flood and Simulation Studies [PDF]

E3S Web of Conferences, 2019
Two potential recovery mechanisms are being considered for a major field which required laboratory measurements to investigate the efficiency of the two scenarios: gas flood followed by water flood and water flood followed by gas flood. Although simply stated,
