The Geophysics Department of GNPC undertakes all geophysical related activities on behalf of the corporation with/without the collaboration of its partners. These activities span across the Exploration and Production (E&P) industry; survey planning, data acquisition, processing through to interpretation, reservoir and field development. Although the department plays significant roles during the acquisition and processing of geophysical data, interpretation of data stands as its paramount business. Geophysicists from the department are always in the field side-by-side the operator at any service location to verify and quality check any data being acquired and/or processed before it comes in-house to undergo our geophysical analyses.

The information technology department manages the IT infrastructure and telecommunication needs of the corporation. The department also delivers effective levels of service and support to the business for on going operational services, new services and projects and also manage the hardware and software assets and ensure compliance with policies and licensing requirements.

The internal audit department exists to provide independent, objective assurance and consulting services to protect, add value and improve the operations of GNPC, including subsidiaries and all related organizations. The department performs pre-audit and post audit activities (risk-based audit) with much emphasis on the latter.
The vision of the department is “To be a driver of innovative change in the management of governance, risk and control issues whilst striving to be the best in class audit function in the upstream Oil and Gas industry”.

The main goal of the Marketing department is the disposal of petroleum resources available to it in such a way to maximize benefits to the corporation and Ghana. It has the mission to source for petroleum resources at competitive prices, brand and market them in an environmentally safe, efficient and cost effective manner so as to increase shareholder value largely using Ghanaian expertise.
The roles and functions of the department include:

1. The disposal of domestic produced crude oil & gas available to the state of Ghana and GNPC (eg. Jubilee crude oil)
2. Managing the government-to-government (G2G) crude oil contracts eg. Nigeria, Equatorial Guinea, Libya etc
3. Importation of products
4. Supporting other departments of GNPC as well as government ministries, departments and agencies with marketing information so that they can perform at optimum levels.

The corporate strategy and new business department provides top-notch petro-business services over the medium to long-term stakeholder, the CE, as well as other department of GNPC.
The department is also in charge of:

1. Corporate and business planning
2. Ensuring effective management of GNPC’s investments portfolio
3. Managing corporate and departmental performance
4. Facilitating GNPC’s efforts to ensuring that GNPC attracts technically and financially capable strategic partnerships
5. Business process improvements
6. External process improvements

The department, together with other departments such as Geophysics and Engineering constitute project teams for all Petroleum Agreements (PA’s) in the country. For each of these blocks under license, the main task of the department is to ensure the execution of the work programs outlined under the budgets of such PA’s. The department undertakes specialised functions, however, the general roles undertaken by staff are listed below:

1. Interpret geological and geophysical  data  to create sub-surface maps of leads and prospects
2. Conduct regional geological studies, basin modeling, source rock modeling, basin analysis, geochemical studies, play and prospect analysis in support of exploration activities
3. Interpret structural and stratigraphic information to support placement of seismic lines
4. Work collaboratively with partners to identify drilling locations for exploration wells
5. Review work done by operators to recommend for acceptance and approval
6. Participate in drilling activities at drill sites
