INTRODUCTION GNPC’S FUNCTIONALITY AND PERFORMANCE AS A NATIONAL OIL COMPANY GNPC since its Establishment in 1985 as a NOC has had the following responsibilities: Custodian of national data assets Safe and secure storage of data on behalf of the nation Deriving value from these data Encouraging new investments into Ghana by making this information available to partners and potential bidders through promotional tours and presentations
OTHERS INCLUDE: o. Management of national hydrocarbon assets: • Ensure that existing and future operators provide all relevant exploration and production data • Ensure that operators are functioning efficiently and in line with national policy o. Act as operator, exploring and developing new plays. Hence GNPC’s Roles are as: Advisor To Government, Regulator and Operator
GOVERNMENTS LEGISLATIVE REGIME TOWARDS PETROLEUM RESOURCE OPTIMISATION The Petroleum Exploration and Production Law, 1984, of Ghana, also referred to as the PNDC Law 84, in its Article 23 (2) states that: “All data and information obtained by a contractor or subcontractor as a result of petroleum operations and all geological, technical, financial and economic reports, studies, interpretations and analysis prepared by or on behalf of a contractor or sub-contractor in connection with such petroleum operations shall be the property of the Corporation”. This mandate therefore enjoins and obligates the Ghana National Petroleum Corporation to safeguard all Exploration and Production Data and their Management. Hence the establishment of its Data Management Center.
The Information Systems, Data Management and Communication Department (ISDM&C) is the Department responsible for all Information and Communications Technology Deployment and Policy Implementation within the Ghana National Petroleum Corporation. The ISDM&C Department has two main sections; namely the Information and Communication Technology (ICT) Section and the Data Management Section.
The responsibilities of the Department could be summarized as follows: To ensure the effective transfer and use in GNPC of appropriate advanced Information Systems Technology relating to petroleum operations including exploration and production; To establish and operate an Exploration and Production Data Management Center, including the maintenance of a technical and archival library for the provision of technical and administrative documentation services; To promote and co-ordinate the utilization of the Corporation’s laboratory facilities to provide routine analysis, technical services and training as part of development activities within the technical departments in support of petroleum operations of GNPC and its partners as well as twinning institutions.
The primary mandate of the Data Management Center is to store originals and copies of all exploration and engineering data. Most of the data in storage are magnetic tapes with seismic, well logs and other engineering data on them. These data forms provide the fundamental source of exploration and engineering data for all work done in the oil and gas industry. They also form the investment and capital asset base of any exploration company, and for that matter the GNPC.
The GNPC responsibility for data organization and promotion has enabled it to embrace the developments in information technology in setting up a wellorganized Data Management Center manned by expertise with immense experience. The Center comprises of a 4000 square feet data warehouse, located in Accra on the Spintex Road, about 22 km in straight line from GNPC’s Head-Offices in Tema. This provides the local storage infrastructure for GNPC. The Center has a Geophysical Data Management Unit for storage of all geophysical data tapes and a Geological Data Management Unit for the storage of all geological data, including well cores and sampling data. The Geological Unit also has a Laboratory Facility for Geochemical, Petrographic and Paleontological Data Analysis. These attributes, therefore, places GNPC in a position to share its knowledge base with its exploration partners, where asset use could be tracked and monitored to guarantee their absolute safety and sustained availability for storage under controlled climatic conditions.
The following broad objectives are being met under the GNPC in-house data storage program: That GNPC develops the core competencies for the management of geoscientific data, including the registration and storage of these, as well as enhancing the degree of their accessibility by potential users off and online. That GNPC directly benefits from technology transfer and the associated training to its staff. That provision of more modern and localized facilities and infrastructure for the Data Center would result in immense savings on overhead expenditures on foreign data storage and management. That the Corporation’s Geoscientists would benefit directly from readily available exploration data for integrated interpretative geoscientific work. That GNPC’s competitive capabilities to attract foreign investment from the international petroleum industry will be drastically enhanced to provide a one-stop shop of data resources and data rooms. That the production and reproduction of data copies and promotional materials up to international standards will be the direct and recursive benefit to accrue from the local management of data. That GNPC would then be in a position to protect and safeguard its national heritage entrusted onto its responsibility.
Hence the Corporation has established operational standards, procedures and guideline policies and regulations on the strategic use, security and upgrade of the Corporations information systems, including equipment and software thereof for monitoring and reporting on compliance.

THE DATA RESOURCE MANAGEMENT
GNPC EFFORTS IN DATA MANAGEMENT After the establishment of GNPC in 1985, the Corporation had to take over responsibility of all Exploration and Engineering data in storage in different locations, both locally and abroad. Some of these data were under storage in commercial data storage houses in the U. K. , where storage charges had to be paid by GNPC annually. Other data, mostly field data acquired by previous partner companies and by the Petroleum Law, had to provide copies to GNPC still had these data sets under their storage due to initial lack of storage facilities in GNPC on its start off. By 1986, just after a year of its being, GNPC had managed to bring in about the first 4000 ½ - inch 9 -track seismic tapes for storage in an air-conditioned room provided it by the Volta River Authority in Akuse. Subsequently, after GNPC’s own custom-built Data Storage Warehouse was completed on the Spintex Road in 1989, several other exploration data were moved into Ghana for storage. These initiatives quickly brought up the number of seismic tapes in different media and formats in storage in GNPC locally up to over 20, 000. All these have now been transcribed onto IBM 3590 and DLT media.
CONDITIONS OF THE DATA The present storage condition of all physical assets is good although there is a definite lack of physical storage space. All transcribed tape copies and originals are stored in the Data Center with a few of the originals stored in Tema. However, documents in a fairly large number are still ‘squirreled’ in users’ offices in Tema. Presently there are 2 documentary databases which have been adapted for Exploration Data and Technical Document Library Management and archiving: they are the ISIS and Library. Soft/Library. World databases. These databases are complete for cores and samples, seismic tapes , logs and sections, books and reports.
OTHER FUTURE ANTICIPATED DATA FROM PRODUCING FIELDS THE JUBILEE PRODUCTION DATA MANAGEMENT SYSTEM
The Jubilee Field was discovered offshore Ghana in 2007. It is an Oil and Gas reserve located in approximately 1, 100 m of water within the Deepwater Tano and West Cape Three Points concession blocks. The Jubilee Field Unit Area is operated by Tullow Ghana Limited.
PLANS FOR ICT INFRASTRUCTURE FOR PRODUCTION DATA MANAGEMENT & ACCESSIBILITY SYSTEMS GNPC through its alignment with the Jubilee Field Partners (Tullow) are designing for implementation the following infrastructural outlays for a PDMS: Utilization of high frequency data from wells, subsea infrastructure and surface facilities for near real-time decisions.
• The collaborative work environments for utilization of high frequency data include: Reservoir performance monitoring Day to day well optimization Production Surveillance Asset Integrity Management Technical Limit Production Short and medium term Production Forecasting Monitoring and Calibrating MPFM (Multiphase Metering) performance Hydrocarbon Allocation and Accounting Daily and Periodic Reporting
This Cutting Edge Production Data Management System would receive Primary Aggregated Data at its Primary Data Hub. A Secure Offsite Back-Up Hub and Disaster Recovery Site is to be provided to GNPC as a parallel infrastructure for real time data delivery after verification and validation. A proposed Data Bank architecture would allow for integration and unification of the PDMS. Consequently, GNPC would require further capacity building and training challenges in terms of short term courses and long term programmes in: 2 D / 3 D Seismic and Well Data Loading into Computer Aided Application Systems ICT Security Management and Access Control of Server and Network Systems Storage and Projects Database Administration.

THE DATA BANK PROJECT A Data Center Data Bank System with Optimized Data Management and Data Administration Workflow Solutions has been proposed by GNPC for World Bank funding support and technical assistance provided under a Norwegian Of. D/NORAD collaboration. The Data Bank would constitute a three tier data integration layer within an electronic data vault system made up of a cluster of data storage platforms and associated software. The Data Bank Common Data Administrator (an application) provides full integrated management of the Data Bank through a GIS Interface.
Integration Layer 1: Loaded Exploration and Engineering data currently in storage on tapes into electronic storage. Integration Layer 2: Scanning and storage of all hardcopy data including Library Reports, Maps, Image Captures of Cores and Sections, and other Bibliographic Materials, in agreed archival formats. Integration Layer 3: Production Database System, storing all Primary Aggregated Data to be received from GNPC’s producing fields for secure secondary storage after validation. Currently, access to the PDMS is through a Portal with a barrage of Firewalls and Security / Access Controlled Facilitations.
