Integrated Petrophysical Evaluation of Turbiditic Sands in Niger Delta Basin
(2014-12-12)Large quantities of petroleum resources in the Niger Delta province are confined to unconsolidated turbiditic and silici-clastic rocks. These rocks are usually associated with high volumes of shale. The high volumes of ...

Evaluation of Oil Recovery Efficiency of Water-Flooding, Gas-Flooding and Wag Injection in a Turbidite Reservoir
(2014-12-12)Worldwide awareness of thin-bedded reservoirs (including turbidites) has become increasingly important with about 30-40% of the world’s oil in-place resources confined within thin-bed laminated reservoirs (Tyagi et al. ...
-
Enhanced Oil Recovery in High Viscous Reservoir using the Thermal Process
(2014-12-12)New sources of energy should be found to relieve the high demand of energy. Even though heavy oil and bitumen are difficult to produce due to their high viscosity which can be reduced by heating, with increased oil price, ...
-
Evaluation of in-fill Well Placement and Optimization Using Experimental Design and Genetic Algorithm
(2014-12-12)Determination of optimal well locations for infill drilling is a challenging task because engineering and geologic variables affecting reservoir performance are often nonlinearly correlated and have some degree of uncertainty ...
-
Mechanistic Models for Predicting Sand Production: a Case Study of Niger Delta Wells
(2014-12-12)Niger Delta Province is predominantly a friable, unconsolidated sandstone terrain suggesting the expectation of sand production while developing hydrocarbon reserves in such terrain. In this study, a simple and easy-to-use ...
-
Effect of Linear Drift on Radial Transport of Tracer in Homogeneous Porous Media
(2014-12-12)Analytical models can be valuable tools to investigate solute transport in porous media. The application of analytical solutions is limited by the perception that they are too cumbersome to derive while their implementation ...
