Functions of capillary pressure and dissolution in the CO2-flooding process in low-permeability reservoirs

Journal of Petroleum Exploration and Production Technology, 2020
CO2 flooding has become one of most effective methods to improve oil recovery in low-permeability reservoirs. Thus, influencing factors have been specifically analyzed for their impact on oil displacement.

A fractal permeability model for the dual-porosity media of tight gas reservoirs

Energy Exploration & Exploitation, 2021
Hydraulic fracturing is a crucial method for the exploitation of tight gas reservoirs. The matrix permeability is a key factor influencing the fracturing result. This paper assumes that the matrix permeability is provided by a series of capillary bundles

Investigating electrical response to water saturation of Agbada sandstone in an x-field Niger delta, Nigeria [PDF]

, 2019
In an attempt to characterize a reservoir in a field, importance is given to living models as it serves critical function in estimating if the reservoir under study is economically viable. Having a good knowledge of electrical response to reservoir rocks

Effects of applied load and its direction on the permeability behavior of concrete: A case study

Case Studies in Construction Materials, 2021
The applied load has significantly impacted on the permeability behavior of concrete. Although many investigations have reported the impact of loading level on the permeability, the influence of loading direction on the permeability received little ...

Frequency-dependent streaming potentials: a review [PDF]

, 2012
The interpretation of seismoelectric observations involves the dynamic electrokinetic coupling, which is related to the streaming potential coefficient. We describe the different models of the frequency-dependent streaming potential, mainly the Packard's

Co-estimation of saturation functions (k r and P c) from unsteady-state core-flood experiment in tight carbonate rocks

Journal of Petroleum Exploration and Production Technology, 2018
The production from oil and gas reservoirs is greatly affected by rock and fluid properties of the porous rock. Capillary pressure (P c) and relative permeability (k r) are two important properties employed in the mathematical simulation reservoirs for ...
