Abstract

Nidoco Field is a large gas field located at the central part of the Nile Delta, along the coast of the Mediterranean Sea. The field stopped production in 2012, due to high water production. Therefore, this work has started to find new opportunities for exploration and production. According to the result of work, new successful wells have been drilled, with huge added reserves in 2015. This work deals mainly with a comprehensive interpretation of the available seismic and well-log data in Nidoco Field. The seismic interpretation was started by generating synthetic seismograms for the studied wells, to link between well-log and seismic data. After good seismic to well tie, detailed seismic interpretation and accordingly geo-seismic cross sections were generated. In addition, complete petrophysical evaluation of the studied wells were studied vertically in the form of litho-saturation cross-plots inferred from the computer processed interpretation (CPI). From these seismic interpretations and petrophysical evaluations, a series of time, velocity, depth, seismic amplitudes, shale content, effective porosity, hydrocarbon saturation and reservoir thickness maps were constructed for the main two reservoirs (Level-2 and Level-3), to have a complete understanding of their geologic properties. The integration of all mentioned data have been allowed the detection of best locations to be drilled and huge gas discoveries have been achieved and production started again from Nidoco Field. Beside that, other new locations are recommended to be drilled, as exploratory and development wells, to produce more hydrocarbons from the study area, which still showing high hydrocarbon potentialities.
