Petrophysical Analysis of Low-Contrast Oil Reservoirs with Low Porosity and Low Formation-Water Salinity in SaPu Intercalation of Longxi Area, Daqing Oilfield, China

open access: yesApplied Sciences
Low-contrast oil reservoirs have a complicated origin story that frequently results from the interaction of several different factors. The low-contrast oil reservoirs in the Daqing Oilfield’s SaPu intercalation in the Longxi Region are the main subjects ...

Estimation of the fracture density in reservoir rock using regression analysis of the petrophysical data

open access: yesGeodesy and Cartography, 2016
Image logs are presently the main specialized tools for fracture detection in hydrocarbon reservoirs. Where image logs are not available, other less rewarding substitutes such as isolated well tests and type curve analysis, drilling mud loss history ...

Petrophysical and geochemical characterization of the late-variscan Santa Eulália Plutonic Complex (Ossa-Morena Zone, Portugal) [PDF]

open access: yes, 2012
The Santa Eulália Plutonic Complex (SEPC) is a calc-alkaline granitic body located in the northern part of the Ossa Morena Zone, composed by a medium- to coarse-grained pink granite (G0 group) involving large elongated masses of mafic (gabbroic) to ...

Bayesian NMR petrophysical characterization

open access: yesJournal of Magnetic Resonance
Identification of reservoir rock types is necessary for the exploration and recovery of oil and gas. It involves determining the petrophysical properties of rocks such as porosity and permeability which play a significant role in developing reservoir models, estimating the volumes of oil and gas reserves, and planning production methods.

A multi-scale approach to determine the REV in complex carbonate rocks [PDF]

open access: yes, 2013
Complex porous carbonates display heterogeneity at different scales, influencing their reservoir properties (e.g. porosity) especially since different porosity types may exist on different spatial scales.
