subsurface energy engineering applications, (ii) provide an understanding of characterisation methods used for describing properties of subsurface fluids used in flow simulators, (iii) utilisation of fluid properties to derive engineering estimates for CCS, geothermal or hydrogen storage processes. On the successful completion of the course, students will be able to:ILO 1: Analyse the dry gas properties relevant to supercritical CO2 storage or H2 storage including isothermal compressibility, density and sonic velocity calculationILO 2: Express the definitions and formulations of properties of subsurface liquids used in reservoir simulationILO 3: Employ material balance technique for identifying drive mechanism in reservoir engineeringILO 4: Calculate the aquifer flux for underground gas storage processesILO 5: Apply the formulation for two-phase flash calculation to determine the reservoir fluid stateILO 6: Explain the CO2 sequestration trapping mechanisms, their time scale, their typical location in the reservoirs, and their safety levelILO 7: Describe miscible/immiscible gas injection processes, their concepts and their performance predictionILO 8: Derive the formulation differences between compositional and black-oil approaches for subsurface fluidsILO 9: Utilise academic (MRST) or industry-standard (ECLIPSE) software packages for CO2/H2 storage for synthetic subsurface systems Lectures provide fundamental aspects supporting the critical learning of the module and will be delivered as pre-recorded asynchronous short videos via our virtual learning environment.Synchronous sessions will support the lecture material with Q&A and problem-solving sessions where you can apply the new concepts. Surgery hours are also available for drop-in support.Students are expected to expand the concepts presented in the session and online by additional reading (suggested in the Online Reading List) in order to consolidate their learning process and further stimulate their interest to the module. 0 Other 25% 1 Written exam 50% 6 Project output (not diss/n) 25% 50% Final exam25% Mid-term exam25% Course project Feedback on problems and examples, feedback on coursework and exams, and model answers will also be provided through the virtual learning environment.
