Impact of methane adsorption on tight rock permeability measurements using pulse-decay

open access: yesPetroleum, 2019
The permeability of the rock is usually measured by the injection of gas using Darcy's flow model (pulse-decay). For oil formations, helium and nitrogen are the most common gases used to measure the permeability of the rock.

Adsorption isotherm on ferrites

open access: yesCommunications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1994
Tlıe corrosion behaviour of the prepared Materials was studied by mcans of weight-loss techniquc in stagnant solution of (0.01 M) sulphuric acid in presence of thiourea as an inhibitor. Higher concentration of thiourea reduces the corrosion rate of thc samples and proteetion effi- cicncy of thiourea was found to be 80 % for ferrites Proteetion is ...
