3D Geometric Modeling of the Abu Madi Reservoirs and Its Implication on the Gas Development in Baltim Area (Offshore Nile Delta, Egypt)‎

Abstract EN

3D geometric modeling has received renewed attention recently, in the context of visual scene understanding.

The reservoir geometry of the Baltim fields is described by significant elements, such as thickness, depth maps, and fault planes, resulting from an interpretation based on seismic and well data.

Uncertainties affect these elements throughout the entire interpretation process.

They have some bearing on the geometric shape and subsequently on the gross reservoir volume (GRV) of the fields.

This uncertainty on GRV also impacts volumes of hydrocarbons in place, reserves, and production profiles.

Thus, the assessment of geometrical uncertainties is an essential first step in a field study for evaluation, development, and optimization purposes.

Seismic data are best integrated with well and reservoir information.

A 3D geometric model of the Late Messinian Abu Madi reservoirs in the time and depth domain is used to investigate the influence of the reservoir geometry on the gas entrapment.

Important conceptual conclusions about the reservoir system behavior are obtained using this model.

The results show that the reservoir shape influences the seismic response of the incised Abu Madi Paleovalley, making it necessary to account for 3D effects in order to obtain accurate results.
