Support Vector Machine Algorithm for Automatically Identifying Depositional Microfacies Using Well Logs

Sustainability, 2019
Depositional microfacies identification plays a key role in the exploration and development of oil and gas reservoirs. Conventionally, depositional microfacies are manually identified by geologists based on the observation of core samples.

A. -Microfaciès / Microfacies

Géologie Méditerranéenne, 1979
On décrit les sédiments de la Mer Pélagienne en établissant les pourcentages des différents constituants, en particulier bioclastiques. Les sédiments sont essentiellement carbonatés avec peu d'éléments terrigènes, sauf près des côtes où il y a beaucoup de quartz et sous les eaux profondes (talus et fosses) où les argiles sont plus abondantes ...

AUTOMATING MICROFACIES ANALYSIS OF PETROGRAPHIC IMAGES

SPWLA 61st Annual Online Symposium Transactions, 2020
Disclosed herein are methods and systems for analysis of a petrographic image of a sample of a subterranean formation, the method comprising performing an unsupervised machine-learning algorithm on the petrographic image, and determining a microfacies or a microfacies characteristic of the sample based on a segmented image provided by the unsupervised ...

Microfacies Interpretation: Summarizing Microfacies Criteria: Microfacies Types

2009
Microfacies studies aim for the recognition of overall patterns that reflect the history of carbonate rocks, by means of a thorough examination of their sedimentological and paleontological characteristics. The previous chapters have shown which thin-section criteria are used in describing the microfacies of limestones. The evaluation of microfacies in
