She has also been greatly involved with training programmes, organized by a company that she ran for several years, the Centre for Petroleum Environment and Development Studies.

Professor Omorogbe's consultancy work has centred mainly on oil and gas, energy, and natural resources law, and her clientele are mainly reputable institutions such as the multinational oil corporations and government agencies.

Yinka Omorogbe has been actively involved with the reform of the Nigerian oil and gas industry for more than a decade. She was a member of the Oil and Gas Sector Reform Implementation Committee (OGIC), constituted by the National Council on Privatisation for the privatisation and reform of the Nigerian oil and gas industry, and for the creation of the National Oil and Gas Policy. She was also a member of the Oil and Gas Sector Reform Committee (OGIC), reconstituted by the late President Yar'Adua to implement the National Oil and Gas Policy, draft a law in line with the Policy, and restructure the Nigerian Oil and Gas Industry. Within that committee she was the Chair of the Legal and Regulatory Subcommittee, which was, inter alia, responsible for drafting the Petroleum Industry Bill that was sent to the National Assembly by the late President Yar'Adua in December 2008. In fact, her appointment into the NNPC was based on the expectation that she would be one of the spearheads for the implementation of Nigerian petroleum industry reform.
