Structural features of continental and oceanic lithospphere and their nature

Геофизический журнал, 2019
The deep geological and geophysical studies of the continents and oceans have revealed a number of well-defined new regularities in the structure of the crust and upper mantle that do not find a clear explanation in the modern geodynamic concepts.

Petrophysics from the air to improve understanding of rock properties in the UK [PDF]

, 2013
Electromagnetic geophysical applications exploit a petrophysical relationship governing the electrical properties of rocks. Given the extensive nature of many airborne electromagnetic surveys it seems natural to classify, and hence simplify, the ...

Bayesian NMR petrophysical characterization

Journal 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.

Modeling of Characteristics of Complex Microstructure and Heterogeneity at the Core Scale

Applied Sciences
Complex pore structures and strong matrix heterogeneity distinguish carbonate rocks, but there is a lack of comprehensive methods to describe these characteristics. In this study, a integrated approach is proposed to improve the accuracy and adaptability

Combined Effect of the Microstructure and Mechanical Behavior of Lateritic Soils in the Instability of a Road Cut Slope in Rwanda

GeoHazards
A very common hazard in Rwanda is represented by the instability of steep road cut slopes in lateritic soil. In its natural state, this material appears as a fine-grained weak and altered rock, generally in unsaturated conditions.

Interpreter of user programs for petrophysical parameters calculation

Revista Cubana de Ciencias Informáticas, 2014
Determining the volume of oil that can be extracted for a given well is vital for the oil industry. In the petrophysical evaluation of training set are used : data taken directly in the well using geophysical logs and process applications that allow ...

A new approach in rock-typing, documented by a case study of layer-cake reservoirs in field

Carnets de Géologie, 2003
In carbonate reservoirs, the relationship between porosity Ø, a measure of the combined volumes of several kinds of pore space (e.g. interparticle and separate-vug), and permeability K are neither linear nor logarithmic, hence only weakly correlatable ...
