Dr. Isah Mohammed

Research Scientist, CIPR

Dr. Isah Mohammed is a Research Scientist at the Center for Integrative Petroleum Research (CIPR), CPG, working at the intersection of interfacial science and subsurface energy engineering. He also serves as a Visiting Consultant to Saudi Aramco, contributing to the advancement of CO2 nanobubble technology for oilfield remediation and improved well injectivity.

Before assuming his current role, he was a Postdoctoral Research Fellow at KFUPM, where he also earned his Ph.D. in Petroleum Engineering. He holds an M.Sc. in Petroleum Engineering from the African University of Science and Technology (AUST), Abuja, and a B.Eng. in Chemical Engineering from the Federal University of Technology, Minna, Nigeria.

His research examines how mineral composition and interfacial charge govern fluid–rock interactions. Key areas include multi-mineral systems, electrical double-layer dynamics, and electrokinetic and dielectric responses. He also develops methods for the early detection and mitigation of asphaltene deposition and other flow-assurance challenges, while advancing the understanding of rock–fluid interactions relevant to carbon capture, utilization, and storage. By combining targeted experiments, molecular simulations, and data-driven modelling, his work aims to translate fundamental interface science into practical technologies for the energy and mining industries.
