Reservoir zonation is the most important job in oil industry which dominantly relies on the major properties of rocks. Fundamental properties of rocks are usually understood by their detailed description in the field (lithofacies analysis) and laboratory (petrofacies analysis). The facies (lithofacies and petrofacies) determination in most subsurface studies is impractical, due to lack of cores...

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...

Abstract Reservoir characterization is one of the key stages in oil and gas exploration, appraisal, development, optimal production. During exploration phase, core analysis well logging are basic information obtained after pay zone identification. This study aims to integrate concept electrofacies (EFs) with hydraulic flow units (HFUs) effectively characterize Permo–Triassic carbonate formation...

Alrededor de 16500 resultados análisis laboratorio petrofísica básica y especial, geoquímica, petrografía orgánica, difracción rayos X, SEM han sido obtenidos a partir muestras roca (core, sidewall core ripios), provenientes formaciones colombianas en etapa exploración delimitación como Yacimientos Roca Generadora (YRG). Contar con gran cantidad información hace necesaria la implementación meto...
