Rock Typing in Gas Shales

All Days, 2010
Abstract Conventional methods of rock typing based on porosity-permeability cross-plots do not work in shales due to lack of dynamic range and difficulties involved in the direct measurements of most of the petrophysical parameters.. Here we present a methodology for rock typing in Barnett shale by integrating geological core description

Two types of alkaline rocks-two types of upper mantle [PDF]

open access: possibleBulletin Volcanologique, 1969
1) Petrochemical studies of volcanic rocks shows that alkaline rocks of continents and oceans are different genetically in spite of their mineralogical and chemical similarity.

New Aspects of Rock Typing

81st EAGE Conference and Exhibition 2019, 2019
Summary It has been tried to analyse different rock typing methods for their performance and accuracy. To do this, a set of capillary pressure, porosity, and permeability data were collected. It was revealed that he FZI* method is capable of identifying different rock types based on heir dynamic/flow properties.

Hydraulic Rock Typing Using Rock Friction Factor - Reynolds Number Type Curves

Proceedings, 2014
Although many studies have been conducted to investigate the gas-flow behavior within porous rocks using the RFI-ReN type curves in the past, to our knowledge, application of the RFI-ReN type curves for hydraulically typing rock samples has not been previously reported.

Revelation of Carbonate Rock Typing – The Resolved Gap

SPE/EAGE Reservoir Characterization and Simulation Conference, 2009
Abstract The heterogeneity in carbonate rocks made it hard for Geoscientist to define a universal classification methodology that is able to honor the critical static and dynamic properties. Most classifications like lithofacies, capillarity & textural methods base their rock typing on one or two static properties then try to find ...

A Novel Type Curve for Sandstone Rock Typing

Petrophysics – The SPWLA Journal of Formation Evaluation and Reservoir Description
Rock typing in heterogeneous sandstone reservoirs remains challenging due to complex pore architectures shaped by depositional and diagenetic processes. This study introduces a pore geometry structure (PGS) crossplot that integrates geological and engineering perspectives to improve rock typing.

Calibrating probabilities for hyperspectral classification of rock types

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
This paper investigates the performance of machine learning methods for classifying rock types from hyperspectral data. The main objective is to test the impact on classification error rate of calibrating the model's output into class probability estimates. The base classifiers included in this study are: boosted decision trees, support vector machines

Dilatancy factor constrained from the experimental data for rocks and rock-type material

International Journal of Rock Mechanics and Mining Sciences, 2014
Abstract The dilatancy is as important property of rock-type (granular, frictional, cohesive, and dilatant) materials as the internal friction, but it is generally ill-constrained and is rarely taken into account in applications, being set to zero. Theoretical analysis shows that the dilatancy factor β strongly affects the onset of the deformation ...

Rock Types, Pore Types, and Hydrocarbon Exploration: ABSTRACT

AAPG Bulletin, 1985
A proposed exploration-oriented method of classifying porosity in sedimentary rocks is based on microscopic examination of cores or cuttings. Factors include geometry, size, abundance, and connectivity of the pores. The porosity classification is predictive of key petrophysical characteristics: porosity-permeability relationships, capillary pressures ...
