Discipline: Engineering
Forecast Models and Evaluation for High Pressure High Temperature Gas Reservoir
Contribution to knowledge:
The study developed models for predicting gas viscosity and z-factor, specifically, for HPHT. A Chart for Z-factor was also developed for Tr of 1.02 to 2.3 and Pr of 0 to 20 that covers non-hydrocarbon ends like CO2 (from 0.32 to 4.21) and N2 (from 0.13 to 2.11). A comprehensive database ranging from low to high temperature and pressure conditions for gas viscosity and z- factor was also built. Documentation of the laboratory procedure for gas z - factor and viscosity experiments for researchers intending to work in this area has also been recorded.
Supervisors:
Dr. Azubuike, Ijeoma Irene, was jointly supervised by Dr. Sunday. S. Ikiensikimama (Department of Gas Engineering, University of Port Harcourt, Nigeria) & Dr. Preye. D. Orodu (Department of Petroleum Engineering, Covenant University, Ota, Nigeria.)
