The present work is denoted to give a comprehensive petrophysical analysis for the Lower Miocene Nukhul Formation in October oil field, Northern Gulf of Suez, Egypt. The coordination between the formation evaluation of well-logs and the subsurface geology of the study area was achieved to estimate the different petrophysical parameters and hydrocarbon potentialities of Nukhul Formation through six wells (OCT-F1 , OCT-F2, OCT-D4, OCT-D1, OCT-D3A and OCT-D5A,). The available log data includes the Vsh tools (Gamma Ray and Self-Potential logs), Resistivity tools (shallow and deep devices), Porosity tools (Sonic, Density and Neutron logs) and caliper log. The volume of shale obtained from gamma ray method gives reliable results. The lithology and porosity identifications have been applied using different methods and techniques. The mineralogical components have been determined from crossplotting different types of porosity. The estimated perophysical parameters are represented vertically through lithosaturation-crossplots to illustrate the vertical variation of the lithology, porosity and fluid contents of the studied formation.
