Statistical analysis methods have been widely used in all industries. In well logs analyses, they from the very beginning to predict petrophysical parameters such as permeability and porosity or generate synthetic curves density sonic logs. Initially, were generated simple functions of other measurements. Then, a result popularisation algorithms k-nearest neighbours (k-NN) artificial neural net...

A thin-bed laminated shaly-sand reservoir of the Miocene formation was evaluated using two methods: high resolution microresistivity data from XRMI tool and conventional well logs. Based on data, Earth model defined in a way that allowed analyzed interval to be subdivided into thin layers sandstones, mudstones, claystones. Theoretical logs gamma ray, bulk density, horizontal vertical resistivit...

Tight oil reservoirs have been a concerned of the industry due to their substantial influence on production. Due poor permeability, numerous problems are encountered while producing from tight reservoirs. Petrophysical and geomechanical rock properties essential for understanding assessing fracability reservoirs, especially enhance permeability. In this study, Saadi B reservoir in Halfaya Iraqi...

Abstract The present work aims to investigate the reservoir characterizations of Lower Cenomanian Baharyia Formation by creating isoparametic maps calculate petrophysical parameters and detect favorable parts for oil accumulations using available well logging data. is one main hydrocarbon sandstone reservoirs in northern Western Desert Egypt. About 90% field produces form Formation. This has be...

Abstract Lower Miocene rift sediments of the Nukhul Formation are one prominent hydrocarbon producers in Gulf Suez basin. In this study, we focused on oil producing sandstones Abu Rudeis-Sidri Field, located east central Suez. is characterized by low amplitude seismic reflectors and represents youngest identified reflector (Lower Miocene) study area. Petrophysical assessment was carried out usi...
