Abstract
Production from thin oil rim reservoirs can be very challenging due to the thin spread of the oil resources, complicated mechanism of production and fluid contact movement. Typically, the recovery ...

These reservoirs are characterized by thin oil column (30–77 ft) with the thick gas cap. The development of these thin oil rim reservoirs is very challenging due to the complexity of the fluid system, complexity of the geology of the field, high heterogeneity in reservoir properties, and strong water drive which is responsible for the observed threat of high water cut
To evaluate and select best development strategy for optimal production from these fields, this study proposes Surrogate Modeling Methodology (SMM) as an alternative to time-consuming and costly Full Field Simulation (FFS) of a horizontal well
Summary
The goal of an oil field development project is the acceleration of the hydrocarbon production and maximization of oil recovery at a minimal cost. Thin oil reservoirs with a huge gas cap are common in the Niger Delta sedimentary basin. Despite having thin pay thickness, these reservoirs still contain substantial volumes of oil-in-place. There are many technical and non-technical issues/ challenges associated with optimal oil rim development. With increasing knowledge of reservoir management and improving production technologies, more complex reservoirs (with respect to location, formation heterogeneities and dimension) can be explored and produced, one of such is the thin oil rim reservoir. Oil recovery in these thin oil rim reservoirs is often difficult because coning or cresting of unwanted fluids is inevitable, leading to low rates of recovery
