Petrophysical applications of NMR imaging
Applied Optics, 1985A system for obtaining high-resolution NMR images of oil field cores is described. Separate proton density and T2 relaxation images are obtained to distinguish between spatial variations of fluid-filled porosity and the physical nature of the pores. Results are presented for typical sandstones.

Experimental Design in Petrophysical Studies: Passive and Active Petrophysical Experiments
Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2006This article describes examples of experimental design, which is the procedure and pattern for obtaining mathematical description or mathematical model of a process or parameter under study as linear or nonlinear regression equation based on the limited number of reproducible experimental data.

Assessment of reliability of petrophysical data during construction of unified petrophysical model
Нефтяная провинция, 2020Активное разбуривание месторождений часто изменяет геологическое представление о залежи при оценке новых исходных данных. В связи с этим, зачастую, пересматривается утвержденная ранее петрофизическая модель, меняются зависимости и, соответственно, начальные геологические запасы.

The principal goal of reservoir characterization is to construct three- and fourdimensional images of petrophysical properties. The purpose of this chapter is to review basic definitions and laboratory measurements of the petrophysical properties porosity, permeability, relative permeability, capillarity, and saturation.

Oil and gas are contained in pores of reservoir rocks such as carbonates and sandstones. In order to assess a possible hydrocarbon reservoir, the porosity and hydrocarbon saturations need to be known, which together define the amount of hydrocarbon per unit volume of rock.

Petrophysical imaging using AVO
The Leading Edge, 1993Seismic lithology is the process by which rock properties—such as lithology, porosity, and pore fluid content—are determined by analysis of seismic and other data. I emphasize other data because the seismic method is limited in what can be achieved in a vacuum, but can be remarkably robust when combined with other information and constrained by ...
