Major structural elements and petrophysical properties of the miocene section, “XYZ Field”, western shallow Offshore Depobelt, Niger Delta

Abstract

R1, R2, R3, and F. reservoir units were identified in the XYZ Field. The reservoirs are within the Oil proven fault block and F reservoir is located on the footwall structure of the second synthetic fault with similar structural characteristics. The faulting in the XYZ field resulted in a downward movement of the XYZ Discovery relative to the XYZ prospects. The structural development process of the field was a syn-sedimentary. This explains why the XYZ-1 penetration in the footwall of the synthetic found oil-in F sand. However, petrophysical results show that the reservoirs of interests have good petrophysical properties with minimum porosity of 0.1 and maximum water saturation of 0.7. The discoveries by the XYZ-1 well prove the existence of a working hydrocarbon source and charge system. However the distribution pattern of the discovered hydrocarbons is not yet understood.
