The onshore Barua Field, near the southeast edge of Lake Maracaibo, is a highly faulted structure producing from the Eocene Pauji and Misoa intervals. This mature field has undergone significant depletion from approximately 30 wells since 1958. A classical, deterministic reservoir characterization study followed by reservoir simulation history matching was conducted. Prior to completing the his...

Abstract The Prediction of the reservoir characteristics from seismic amplitude data is a main challenge. Especially in Nile Delta Basin, where subsurface geology complex and reservoirs are highly heterogeneous. Modern characterization methodologies spanning around attributes analysis, deterministic stochastic inversion methods, Amplitude Variation with Offset (AVO) interpretations, stack rotat...

Bleaching patterns along a faulted succession provides new insight into fluid migration pathways controlled by the fault zone and mechanical stratigraphy. In order to investigate this effect, we logged stratigraphic layers in Humbug Flats, Utah, USA both host rocks rocks, where 40 m offset normal cuts through Entrada Sandstone. We measured petrophysical properties using TinyPerm II, Schmidt Ham...

Abstract One of the challenges in reservoir management is determining fracture density (FVDC) rock. Given high cost coring operations and image logs, ability to predict FVDC from various petrophysical input variables using a supervised learning basis calibrated standard well extremely useful. In this study, novel machine approach developed 12-input variable well-log based on feature selection. ...

Dual-domain models are used to explain anomalous solute transport behavior observed in diverse hydrologic settings and applications, from groundwater remediation to hyporheic exchange. To constrain such models, new methods are needed with sensitivity to both immobile and mobile domains. Recent experiments indicate that dual-domain transport of ionic tracers has an observable geoelectrical signa...

Estimation of fluid saturation is an important step in dynamic reservoir characterization. Machine learning techniques have been increasingly used recent years for prediction workflows. However, most these studies require input parameters derived from cores, petrophysical logs, or seismic data, which may not always be readily available. Additionally, very few incorporate the production reflecti...

Significant amounts of information are rapidly increasing in bulk as a consequence the rapid development unconventional tight reservoirs. The geomechanical and petrophysical characteristics wellbore rocks influence sweet non-sweet areas Using standard approaches, such data from cores commercial software, it is difficult costly to locate productive zones. Furthermore, apply these techniques well...

Geomechanical studies are very important in the development stages of oil fields to solve many problems such as wellbore instability and sand production. However, this study is not complete without availability mechanical properties rocks. These estimate from petrophysical logs based on compressional shear wave velocities. But often missing most wells, reason might be cost-saving. Therefore, ai...

Abstract Otan-Ile field, located in the transition zone Niger Delta, is characterized by complex structural deformation and faulting which lead to high uncertainties of reservoir properties. These greatly affect exploration development thus require proper characterization. Reservoir characterization requires integration different data such as seismic well log data, are used develop model. There...

Shale oil reservoirs differ from conventional in several aspects, including the sedimentary model, accumulation mechanism, and reservoir characteristics, which pose significant challenges to their exploration development. Therefore, identifying location of optimal spots is crucial for successful development shale reservoirs. Mobility, particularly low-permeability with nano-scale pores, a petro...
