NMR Relaxation and Petrophysical Properties

AIP Conference Proceedings, 2011
NMR relaxation is routinely used in the field of geosciences to give basic petrophysical properties such as porosity, pore size distribution, saturation etc. In this tutorial, we focus on the pore size distribution deduced from NMR. We recall the basic principle used in the interpretation of the NMR signal and compare the results with other standard ...

Measuring Marcellus Shale Petrophysical Properties

SPE Western Regional Meeting, 2016
AbstractThe advances in hydraulic fracturing and horizontal well technology have unlocked considerable reserves of hydrocarbon contained in shale formations. However, quantification of the key shale petrophysical properties remain challenging. It is not practical to measure the permeability of the unconventional formations such as shales by standard ...

Acoustic and Petrophysical Properties of Sea-floor Bedrocks

Offshore Technology Conference, 1996
Abstract There are few published velocity and attenuation data for sea floor bedrocks at appropriate confining pressures (1 MPa to 10 MPa). Velocities and attenuations measured at such low pressures are affectedmainly by open microcracks, However, as the pressure is increased and the microcracks are closed, the ...

Petrophysical Properties of Seals

AAPG Bulletin, 1991
Seals are defined as generally ductile rocks with a very high capillary entry pressure that can dam up hydrocarbons. Petrophysical and petrographic studies of conventional and sidewall cores from known seal-reservoir couplets of hydrocarbon-producing reservoirs provide a basis to quantify the capacity of a rock to seal a hydrocarbon column.

Integrated Lithofacies and Petrophysical Properties Simulation

SPE Western Regional Meeting, 1997
Abstract This paper presents a new procedure that simultaneously generates consistent distributions of categorical lithofacies and continuous petrophysical properties, i.e., porosity and permeability. The technique used is the conditional simulation method which is capable of honoring the original distribution of ...

Machine-Learning-Based Petrophysical Property Modeling

SPE Europec featured at 81st EAGE Conference and Exhibition, 2019
Abstract The current cycle for reservoir management requires several months to years to update static and dynamic models as additional data from the field [logs, production, pressures, core, four-dimensional (4D), etc.] are obtained. These delays in updating the models result in increased risk and contribute to a significant loss of ...
