Application of Seismic Data Interpretation and Well Log Analysis for Evaluation of Matulla Formation South Abu Zenima Oil Field Gulf of Suez Egypt.

The objective of this Study work is to conduct a comprehensive geophysical evaluation of oil potential within the Late Cretaceous Matulla Formation in the Abu Zeinima oil field using well logs and seismic data interpretation. The geophysical interpretation made use of a Pre-Stack Depth Migration seismic volume with 10 seismic lines covering the study area. Using PETREL software, a structural contour map was created for the top of Matulla Formation, revealing the existence of NW-SE normal faults. These faults play a crucial role in creating structural traps.IP software was used to evaluate the petrophysical properties of four wells in the Matulla Formation. Based on this evaluation, isoparametric maps for gross thickness, shale volume, net reservoir, net/gross ratio, net pay, water saturation, and hydrocarbon saturation were developed and merged into the structural map. These maps are concentrated on the eastern side of the field due to the location of the provided wells.Good net reservoir thickness (between 15 and 60 meters), a fair to good net/gross ratio (between 0.12 and 0.54), shale volume (between 0.05 and 0.30), good effective porosity (between 0.11 and 0.16), with high water saturation (between 50% and 100%), and hydrocarbon saturation (between 0% and 50%) are all displayed from the evaluation of Matulla reservoir. The maps suggest focusing on the southeast part of the area for more possible development locations. Furthermore, there are other possible exploration locations, especially in the upthrown block of the main producing block and the west blocks, based on the structural setting.
