Summary: | The discovery of more hydrocarbon wells remains a major recipe to boost the economy of
Nigeria, a major oil producer in Africa. The seismic method is prominent for identifying traps
in the oil explorations, but cannot indicate if the trap host hydrocarbon. This gap is usually
filled by the radiometric method, its characteristics around the Kolmani well 1 have hitherto
not been reported. This research focused on identifying promising locations for hydrocarbon
accumulation around the Kolmani Well 1 while using the well as a control. To achieve the
objectives of this research, the nature of the radioelements was observed over the Kolmani
well1 and the outcome of normalizing potential and uranium was also identified. The average
values of potassium (K), thorium (Th), and uranium (U) are 0.277%, 8.917 ppm, and 1.431
ppm respectively. The concentration of the three radioelements, K, Th, and U, decreases over
the oil well. This was ascribed to enhanced leaching of natural radioelements caused by
hydrocarbon-generated groundwater acids. The result of the normalization of K with Th yields
a low concentration of K over the Kolmani well1 and the normalization of U with Th yields a
high concentration of U over the Kolmani well1. These were in tandem with the report on the
application of the method in previous locations. Hence, the results of the normalization of K
and U were used to identify four locations with potential for hydrocarbon exploration. The
viability of these locations was confirmed with the positive DRAD (Delineation of Radiometric
anomalies) value (ranging from -5.1 to +5.2), a pointer to hydrocarbon accumulation in an area,
recorded in these locations and the location of the Kolmani well 1. |
