Dunni has had a very exciting legal career in Corporate Nigeria spanning two decades mostly in the downstream and upstream sectors of the Nigerian oil and gas industry. She has built for herself a solid reputation as one of very few Nigerian oil and gas lawyers to have set up from scratch and managed full-fledged legal departments in international Oil and Gas companies in Nigeria such as Addax Nigeria Limited (an affiliate of the Addax Oryx Group) and more recently Petroleo Brasileiro Nigeria Limited (an affiliate of the Petrobras Group). She is a Partner with the firm.

Notable Work Undertaken

In this capacity, Dunni has negotiated, reviewed and drafted various core and allied oil and gas agreements including Production Sharing Contracts, Joint Operations Agreements, Engineering Contracts, Collective Bargaining Agreements with Unions, and Service Contracts, to mention a few. She has also advised on various aspects of oil and gas operations in Nigeria necessitating her application of Nigerian oil and gas legal framework and her appreciation of laws of foreign jurisdictions.

She has also provided strategic advice and support as and when necessary. Her role also covered various aspects of legal compliance tasks with various regulatory bodies in Nigeria. During this period, she interacted very closely with her professional peers in the local and international oil and gas industry. Prior to this period, she worked for a number of years in leading Nigerian commercial and litigation law firms where she was responsible for managing the legal affairs of high net worth individual clients and key corporations in various sectors of the Nigerian economy.

Dunni has attended several international
conferences on oil and gas and related areas. She
has also served as a resource person at a number
of professional workshops.
