Presalt reservoirs of the Santos Basin: Cyclicity, electrofacies, and tectonic-sedimentary evolution
Interpretation, 2019Presalt reservoirs of the Santos Basin accounted for more than 50% of Brazilian hydrocarbon production in the first two months of 2019. Its most important reservoirs are found in the Barra Velha Formation; thus understanding its genesis and geologic history is essential.

Novel Approach to Link Petrophysical Groups into Electrofacies by using NMR Logs
Abu Dhabi International Petroleum Exhibition & Conference, 2020Abstract Petrophysical Groups (PG) from cores and log facies (electrofacies) are two of the main outputs generated in the petrophysical domain. Those are particularly contributors to the highest degree of uncertainty during the reservoir modeling, with the subsequent high-impact in field development decisions.

Determination of Electrofacies in Carboniferous Sediments of Lublin Basin, Poland
Proceedings, 2015Lithological facies can be described by field observations or observations of cores. What is more, facies can be determined from well-logging data. Thus, the term “electrofacies” should be used. Determination of electrofacies in silty-shaly carboniferous profile (without cores and petrographical description of wells) can be successfully obtained by ...

Proceedings of SPE Asia Pacific Oil and Gas Conference and Exhibition, 1997
Abstract A quantitative and systematic methodology is presented for the prediction of the lithology using electrofacies determination from well log data. Multivariate statistical techniques are adopted to segment wireline log measurements and group the segments into electrofacies types.

FUZZY PARTITIONING SYSTEMS FOR ELECTROFACIES CLASSIFICATION: A CASE STUDY FROM THE MARACAIBO BASIN
Journal of Petroleum Geology, 2001This paper describes a method of advanced data processing for the inverse problem of lithofacies prediction from well logs using fuzzy partitioning systems. A fuzzy partitioning system consists of a set of fuzzy If‐Then rules of the form “If bulk density (pb) is low and neutron porosity (øCNL) is high Then classify pattern x=(pbøCNL) as Fades Fi”.

Electrofacies and Geological Facies for Petrophysical Rock Typing: Khuff C
SPE Saudi Arabia Section Technical Symposium, 2009Abstract For integrated reservoir characterization a translation scheme must be established to link subsurface data across the disciplines, from the seismic and geological through the petrophysical to the reservoir dynamic properties. This translation process requires data sets that cross discipline boundaries and that establish robust ...
