This thesis analyses the patterns of mismanagement and
corruption in Nigeria’s oil revenue institutions from 2005–2023
through qualitative document analysis. By comparing audits,
financial statements, and policy reports, it identifies
systemic revenue leakages, weak enforcement, and persistent
institutional failures. The findings show that institutional
weakness have significantly limited the developmental impact of
Nigeria’s oil wealth and despite several reforms, enforcement
failures make it im-possible to convert oil wealth into
sustained development.
