qualitative analysis of petroleum reservoir rocks is still one of the most important topics of core laboratories and directly affects hydrocarbon-in-place, fluid flow, and prediction of field performance. magnetic resonance imaging (mri) as a non-invasive, millimeter resolution technique which only images fluids in porous media fits this purpose perfectly. magnetic resonance is a radio frequenc...

The injection of carbon dioxide (CO2) in deep, unmineable coalbeds is a very attractive option for geologic CO2 storage: the CO2 is stored and at the same time the recovery of coalbed methane (CBM) is enhanced. The revenue of methane (CH4) production can offset the expenditures of the storage operation. Coalbeds form complex gas reservoirs characterized by their dual porosity: they contain both...

Nanofibers are one-dimensional nanomaterialswith a superfine diameter and many potential applicationsdue to their desirable characteristics such as small diameter,high surface area, high flexibility, high porosity, and specialmechanical properties. In the recent years, porous nanofibershave been the subject of considerable research works in awide range of app...

porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. it is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. there are three main petrophysical...
