NMR Relaxation and Petrophysical Properties
AIP Conference Proceedings, 2011NMR 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, 2016AbstractThe 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, 1996Abstract 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, 1991Seals 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, 1997Abstract 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, 2019Abstract 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 ...

1999
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.

Petrophysical Properties of Nigeria Tarsand Revisited
SPE Nigeria Annual International Conference and Exhibition, 2015Abstract Heavy oil and Bitumen from tar sands are important energy assets, and have the potential to significantly contribute to the overall energy supply in Nigeria. Nigeria tar sand deposits are found in large accumulations, notably, in huge outcrops in the South-Western region.

Measurement of Key Shale Petrophysical Properties
SPE Annual Technical Conference and Exhibition, 2015Abstract Even though the advances in hydraulic fracturing and horizontal well technology have unlocked considerable reserves of hydrocarbon contained in shale formations, quantification of the key petrophysical properties in shale reservoirs still remain challenging.
