THE GAMBIA PETROLEUM COMMISSION

Data Management

Exploration in the Gambia’s Petroleum sector included surveys principally comprising of geophysical and geological investigations. These investigations have been going on since the fifties and have led to the generation of huge volumes of valuable data that represent asset. These data and information assets need to be managed as envisaged by Section 5 (k) of the Petroleum Commissions Act, 2021 which mandated the commission to amongst others manage the national petroleum repository.

All Geophysical data acquired in the Gambian jurisdiction by Government, its partners are properties of the Government regarded as valuable national resource and asset. Such value can be significantly increased through a proper data management system.

The data management system currently being developed provides a framework for the collection, standardization, storage, security, maintenance, and dissemination of geophysical and geological data. The details on how this will be attained will be elaborated in a stand-alone data management policy.

Objective

To establish a comprehensive data management system and solution, that integrates the physical, digital data and information into a one stop shop, making it easily accessible to enhance exploration in the Gambia.

Data Types

These data exist in various formats, including paper copies, digital, cartridges and hard drives, covering best part of Gambian jurisdiction. 

The specific objective of the Commission’s data management program is to create a comprehensive catalogue of all these geophysical and geological data, maintain a digital library that is accessible globally, and establish a physical data center that is accessible within country.

Coverage:

3D Volumes: There are number of volumes of 3D seismic data and reprocessed versions of these data covering, A0, A0DW, A1, A2, A4 and A5. Details on each of these surveys are as provided below:

Others: Bathymetric, gravity, and magnetic data are essential tools for exploring and understanding the geology and seafloor topography. The Gambia’s prospective areas A1, A2, A3, A4, A5, and A6 are extensively covered with gravity and magnetic data, with bathymetric data only available for A0, A1, A2, A4 and A5.

There have been five wells (Brikama, Sarakunda, Jammah-1, Samo-1 and Bambo-1) drilled over the Gambia’s jurisdiction, resulting in extensive volume of cuttings, logs and a number of cores.
