Integration of Well Log Evaluation and Seismic Attribute Analysis and its Impact on the Reserve Estimation for Some Reservoirs on the North East, Onshore Wells Nile Delta

Abstract

The Nile Delta basin is a highly prolific gas and condensate province with discoveries from different plays. Proven reservoirs within the Nile Delta cone vary in age from Oligocene to Pleistocene. Exploration activities started in 1947 by Standard Oil Company of Egypt that carried out a number of reconnaissance gravity surveys. In 1967, the International Egyptian Oil Company (IEOC) drilled the Abu Madi-1 well and made the first gas discovery from the Messinian Abu Madi Formation in the onshore Nile Delta. The Messinian is considered as one of the favored plays in the Nile Delta due to its relatively shallow depth and relatively normal pressure. In 2004, El Wastani Petroleum Company drilled El Wastani East-2 well situated in the West El Manzala concession and encountered hydrocarbons in the Messinian Abu Madi Formation. The company has focused on this play and made a series of discoveries. This study involves seismic interpretation and petrophysical evaluation of a number of wells in the West El Manzala area. The seismic interpretation concludes the presence of two 4-way dip closures dissected by a series of normal faults. Seismic amplitude extractions show the presence of high amplitudes within parts of the study area which reflect the reservoir presence.
