Reservoir Modeling Analog Project (RAMP) group focuses on 3D investigation of inter-well scale depositional heterogeneities in the Upper Jurassic reservoir sequences using outcrops. The primary aim of the group is to assess the impact of depositional and structural heterogeneities (facies, layer architecture & fractures) on future reservoir developments such as infill drilling and enhanced oil recovery schemes. Our research utilizes an integrated workflow of geological and geophysical investigations including behind the outcrop cores, multi-scale drone photogrammetry, hyper-spectral imaging, and near-surface behind the outcrop seismic, ground-penetrating radar (GPR) datasets (combined with traditional sedimentological measured sections and thin section petrography).


Detailed inter-well scale heterogeneities of carbonate reservoirs such as facies dimensions and layer architecture are commonly not assessed appropriately because the resolution does not exist to recognize them in the subsurface from seismic and well data. The datasets collected will provide improved input for static models and dynamic simulation of Hanifa and Arab-D reservoirs, which will contribute to assessing current reservoir behavior and decision making for future developments improving ultimate recovery.

Project: Optimizing Ultimate Recovery from Arabian Jurassic Hydrocarbon Reservoirs

The project includes:

1)    Modelling depositional architecture of the Late Jurassic Hanifa and Arab-D Fms.

2)    Testing models under different recovery scenarios.
