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

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 ...

When Capillary Permeability Increases
, 1987 Capillary permeability is usually ascribed to a number of "small" pores. In this article the small-pore pathway is identified as interruptions in the tight junctions between endothelial cells.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation
FEBS Letters, EarlyView.Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Permeability prediction and drainage capillary pressure simulation in sandstone reservoirs [PDF]
, 2005 Knowledge of reservoir porosity, permeability, and capillary pressure is essential to exploration and production of hydrocarbons. Although porosity can be interpreted fairly accurately from well logs, permeability and capillary pressure must be ...
