Assessment of parameters effectiveness in the reserve estimation methods applicable to coal bed methane reservoirs
Kirmani, Farzain Ud Din; Raza, Arshad; Akram, Muhammad Sarfraz; Gholami, Raoof (Peer reviewed; Journal article, 2022)The reserve estimation of coal bed methane (CBM) reservoirs is ascertained through the analytical methods (volumetric method, material balance equation and decline curve analysis). However, the adoption of reserve estimation ... -
Characterization based machine learning modeling for the prediction of the rheological properties of water‑based drilling mud
Ismail, Atif; Awais Rashid, Hafz Muhammad; Gholami, Raoof; Raza, Arshad (Peer reviewed; Journal article, 2021)The successful drilling operation depends upon the achievement of target drilling attributes within the environmental and economic constraints but this is not possible only on the basis of laboratory testing due to the ... -
Hydrogen diffusion into caprock: A semi-analytical solution and a hydrogen loss criterion
Ghaedi, Mojtaba; Andersen, Pål Østebø; Gholami, Raoof (Peer reviewed; Journal article, 2023)Depleted gas reservoirs can provide a gigaton capacity and the necessary infrastructure for large scale hydrogen storage. Therefore, underground storage of hydrogen in these geological formations is considered a valuable ... -
Maximum column height and optimum storage depth for geological storage of hydrogen
Ghaedi, Mojtaba; Andersen, Pål Østebø; Gholami, Raoof (Peer reviewed; Journal article, 2023-12)We formulated the maximum hydrogen column height that avoids capillary breakthrough into the caprock above saline aquifers and depleted gas reservoirs. The effects of potential cushion gases such as methane, carbon dioxide, ... -
Mixing dynamics and recovery factor during hydrogen storage in depleted gas reservoirs
Ghaedi, Mojtaba; Andersen, Pål Østebø; Gholami, Raoof (Peer reviewed; Journal article, 2024-06)Large-scale hydrogen storage is strategically important for society and depleted gas reservoirs have been proposed as a potential solution. However, the mixing with remaining hydrocarbon gas during injection/production ... -
A Novel Empirical and Deep Ensemble Super Learning Approach in Predicting Reservoir Wettability via Well Logs
Otchere, Daniel Asante; Mohammed, Mohammed Abdalla Ayoub; Ganat, Tarek Omar Arbi; Gholami, Raoof; Merican, Zulkifli Merican Aljunid (Peer reviewed; Journal article, 2022)Accurately measuring wettability is of the utmost importance because it influences several reservoir parameters while also impacting reservoir potential, recovery, development, and management plan. As such, this study ... -
Numerical modelling of a high temperature borehole thermal energy storage system: Norway case study
Awadelseed, Abdelazim Abbas Ahmed; Assadi, Mohsen; Gholami, Raoof; Ahmed, Naveed (Peer reviewed; Journal article, 2023)Global warming is threatening life on earth. Utilising renewable energy is considered as the most effective measure to minimise anthropogenic CO2 emissions. High-temperature borehole thermal energy storage (BTES) systems ... -
Optimum directional well path design considering collapse and fracture pressures
Farzay, Oveis; Shakhouri, Ali; Gholami, Raoof; Al-Ajmi, Adel M. (Peer reviewed; Journal article, 2022)Well path optimisation is often done based on the wellbore stability where the production related concerns are ignored. In fact, many of the studies carried out in the past have not included hydraulic fractures into their ... -
Underground hydrogen storage (UHS) in natural storage sites: A perspective of subsurface characterization and monitoring
Luo, Xiaodong; Tveit, Svenn; Gholami, Raoof; Andersen, Pål Østebø (Peer reviewed; Journal article, 2024-05)With the long-standing efforts of green transition in our society, underground hydrogen storage (UHS) has emerged as a viable solution to buffering seasonal fluctuations of renewable energy supplies and demands.
