USING WELL LOG DATA AND SEISMIC DATA FOR THE PREDICTION OF CO2 EVOLUTION IN SOILS, NIGER DELTA AREA, SOUTHERN NIGERIA

The nature of hydrocarbon production activties in Niger Delta have been charactrized by gas flaring which have induced higher concentration of atmospheric CO2 in the study area. knowing the region of hydrocarn accumulation is a precusor to determination of CO2 migration. Therefore this study was carried out to predict the evolution of carbon dioxide in the Niger Delta, Southern, Nigeria using integrated well log and seismic data. Reserviors with hydrocarbon accumulation was delinated using well log and was mapped across the field in the petrel interface to generate reservior surfaces, follwed by faults mapping which are migration pathways for Hydrocarbon migration or seal. The depth surface maps of the mapped horizons( R1-R3) with the R1-reservoir as the deepest (29116ft) and the R3-reservoir as the shallowest (2316ft), this indicated that area of structural highs marked with yellow-red coloration are the prospective zones while the area of structural low with purple-blue coloration as the source area of the hydrocarbon. The Root Mean Sqaure Surface attributes maps revealed that the area of structural high are the are of hydrocarbon dominance which act as the major carrier of carbon dioxide. The reservoir with the highest Root Mean Square bright amplitude were ranked as follows, R1> R2>R3 and it was observed that the hydrocarbon have migrated up dip through the faults zones
