Oil & Gas Administration System  

Management of blocks and licenses for exploration and production, 

promoting investment and transparency

OGAS is similar to MCAS, but designed and configured to manage oil and gas blocks, tenders and concessions.

The system allows available blocks to be defined, register applications/bids with all documentation and finally allocate the license to the winning bid. The license lifecycle is then managed with automated fee calculations and monitoring of reports.

OGAS was first adopted by the Government of Mali Oil and Gas Directorate AUREP.

OGAS 1.0 Blocks Module

Does it have GIS features for allocating blocks?

Yes, the system has a full GIS Server embedded in the installation, using GeoServer. Is uses open standards set forth by the Open Geospatial Consortium (OGC) and is compatible with ESRI GIS systems, shape files and KML file standard. 

How good is the data security?

RDF systems use the latest we security frameworks and installed on servers with https secure protocol, following international best practice in data security. As part of the installation, backup procedures are implemented and the server is installed with RAID redundancy configuration to avoid possible hard disk failure causing loss of data.

How much does the system cost?

RDF systems are provided without license fees or any recurrent software license costs for government institutions in low-income countries by RDF as a non-profit consultancy organization. Client institutions must adhere to the RDF Condtions of Usage, which is referring to revenue accountability described in the respective country's legislation. The project cost of implement the system is determined by how much time RDF staff are spending with the client to implement it. 

How is the project implementation funded?

The projects implementing RD systems are usually funded by development partners in-country as a two-year capacity development project.
