USING 3D SEISMIC AND WELL LOG DATA

This project work is focused on the volumetric estimation of Agbeju Field, Niger Delta using 3Dseismic data and well logs. Data used for this project include 3-D seismic data in SEG-Y format and suites of five well logs (Agbeju 01, Agbeju 02, Agbeju 03, Agbeju 04 and Agbeju X01). 9 major faults and 24 minor faults were delineated on the seismic data. The lateral extent of 3 hydrocarbon bearing reservoirs were delineated and mapped as blocks (Sand A, Sand B and Sand C) and evaluated showing the petrophysical values across the reservoirs having average porosity of 0.32, average pay thickness of 98.46ft, average net-to-gross ratio of 0.84, and average water saturation of 0.625. From prospect identification, the area of the drilled prospects within the reservoirs ranges from 452.8634 acres – 1196.512 acres. The estimated volumes of hydrocarbons within the drilled prospects is given by Gas initially in place for Sand A (554MMSCF), Sand B (163MMSCF) and Sand C (258MMSCF) and Oil initially in place for Sand B (22.4MMBBL) and Sand C (83.93SMMBBL). The result of the characterization of these reservoirs shows good productive sands with fair to good hydrocarbon saturation of 0.375, with sufficient hydrocarbon volumes necessary for field development and production.
