Zarool Hassan Tajul Amar

Petrophysics & Formation Evaluation

Zarool Hassan Tajul Amar is a highly experienced petrophysicist with 34 years in petrophysical evaluation and a further four years in wireline and logging-while-drilling operations. His career includes roles with Schlumberger, PETRONAS Carigali, Saudi Aramco’s Reserves Assessment Division, and Vestigo Petroleum. His expertise lies in formation evaluation, log interpretation, integrated petrophysics, and the use of geological and reservoir-engineering data to improve subsurface understanding and support optimum hydrocarbon exploitation.

His profile reflects both long-term technical depth and strong industry recognition. He was featured at the 2025 EAGE/FESM Joint Conference on Innovative Petrophysics, and SPE records show him as a co-author of a 2025 paper on advanced cement evaluation in complex wellbore completions. Public SPE records also show his technical authorship going back to the mid-1990s, which points to a long and sustained contribution to industry knowledge and practice.

From a consultant perspective, Zarool can help upstream companies reduce uncertainty in reservoir characterization, improve petrophysical interpretation, strengthen well and completion decisions, and raise the technical capability of in-house teams. Because his background combines operations, evaluation, cross-disciplinary integration, and training delivery, he is especially valuable for organizations that want both expert technical problem-solving and structured knowledge transfer to engineers, geoscientists, and asset teams.
