An appraisal of the Abura Field

Abstract

Petrophysical analysis was carried out for all the identified hydrocarbon intervals, from the four wells studied
in the Abura Field using suites of geophysical well logs. From the analysis of the geological logs comprising
gamma-ray, spontaneous potential, electrical resistivity, neutron and density logs, the total porosity in the
hydrocarbon bearing zone was found to range from 18.0% to 28.0% and the water saturation range from 16.0 to
54.0%. Good well-to-well lithologic correlation was established across the fields studied .The researcher found
that the bulk of the hydrocarbon encountered in the Niger Delta basin was found to be within a depth range of
2510.0-3887.0 m. The hydrocarbon reservoirs were found to be in the Agbada formation, which is in conformity
with the geology of the Niger Delta, Nigeria. This study was carried out to find out if the petrophysical
parameters computed in the field will encourage deeper drilling in the area of study.
