Exploration History (Cont’d)1. 1957 Independence from UK – then first oil and gas fielddiscoveries2. 1966 – 1967 Government of Ghana contracted Romanianexploration team3. 1970 - Signal Oil discovered Saltpond Field offshore withinDevonian. Estimated oil in place 45 million barrels, on stream1978 and farmed out Primary Fuels Inc. (PFI).4. 1970 - Volta Petroleum find oil in Volta Tano-1X, in first offshoreTano well5. 1973 - Zapata discovers first offshore gas with Cape ThreePoints-1X6. 1978 -1980 Phillips discover oil & gas in North and South Tano7. 1985 - PetroCanada International Assistance Corp (PCIAC)8. 1985 to date – GNPC became fully operational.

Regulatory Frameworks GNPC Law (PNDCL 64) of 1983 Exploration & Production Law (PNDCL 84) Petroleum Income Tax Law (PNDCL 188) Model Petroleum Agreement for Exploration andProduction (not a law) Drafted for GNPCOperations.

GNPC’S FUNCTIONALITY AND PERFORMANCE ASA NATIONAL OIL COMPANYSince becoming fully operational in 1985 as a NOC, GNPC hashad 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 makingthis information available to partners and potentialbidders through promotional tours and presentations.

OTHERS INCLUDE:oManagement of national hydrocarbon assets: Ensure that existing and future operators provideall relevant exploration and production data Ensure that operators are functioning efficientlyand in line with national policyoAct as operator, exploring and developing new plays.Hence GNPC’s Roles are as:1. Advisor To Government In Policy Formulation;2. Assisting In Regulatory Functions;3. And A Commercial Operator.

The above functions 1 and 2 have beentaken over by the Petroleum Commissionwhich was established during 2011 by anact of Parliament. The objective of the Commission is tomanage and regulate the utilization ofpetroleum resources and to coordinate thepolicies in relation to them. GNPC still has a role to play due to lack ofcapacity of the PCG.10

GNPC will ensure the completeness of alldatasets delivered to the PCG and inaccordance with agreed quality standardsand procedures GNPC will ensure that analogue data willbe correctly converted to digital formatsaccording to set specifications andprocedures.11

Concessions Currently, there are overeighteen (18) offshore licenceswith various companiesoperating in the basins.

DISCOVERIESAs early as 1896, wells were drilled in and around Half-Assini as a result of oil seeps found onshoreTano basin. Today one can still see some of these seeps at bokakere. Between 1978 and 1985 oilwas produced from the Saltpond field.A number of oil, oil/gas and gas fields have been found in the tano basin. In all over 143 wells havebeen drilled in the country and over 13 discoveries have been made. It is also worth mentioning that75% of 50 exploratory wells drilled encountered varying degrees of hydrocarbon shows.FieldBasinYearFluid typeSaltpondSaltpond1970Oil & GasCape Three PointsCape Three Points1973GasSouth Tano MainBlockTano1978Oil & GasSouth Tano 3-AXBlockTano1979GasNorth TanoTano1980Oil & GasCTSTano1989GasWest Tano - 1Tano2000OilJubileeTano / West CTP2007Oil & GasSankofaCape Three Points2008Oil & GasOdum-1Cape Three Points2008OilTweneboaTano Deep2009Gas, Condensate/OilDzata 1Tano/CTP2010Gas, Condensate/OilOwo-1Tano Deep2010Oil and Gas

Data Management Practices

GNPC EFFORTS IN DATAMANAGEMENT1986- GNPC managed to bring in about the first 4000 ½ - inch 9-trackseismic tapes for storage in an air-conditioned room provided it bythe Volta River Authority in Akuse.1989 GNPC’s own custom-built Data Storage Warehouse wascompleted in Accra, several other exploration data were moved intoGhana for storage. These initiatives quickly brought up the numberof seismic tapes in different media and formats in storage in GNPClocally up to over 20,000.2011 All these have now been transcribed onto IBM 3590 and DLTmedia.

The ISDM&C The Information Systems, Data Management andCommunication Department (ISDM&C) is theDepartment responsible for all Information andCommunications Technology Deployment and PolicyImplementation within the Ghana National PetroleumCorporation. The Department has two main sections; namely theInformation and Communication Technology (ICT)Section and the Data Management Section.

The responsibilities of the (ISDM&C) are asfollows To ensure the effective transfer and use in GNPC ofappropriate advanced Information Systems Technologyrelating to petroleum operations including exploration andproduction; To establish and operate an Exploration and ProductionData Management Center, including the maintenance ofa technical and archival library for the provision oftechnical and administrative documentation services; To promote and co-ordinate the utilization of theCorporation’s laboratory facilities to provide routineanalysis, technical services and training as part ofdevelopment activities within the technical departments insupport of petroleum operations of GNPC and its partnersas well as twinning institutions.

The Data Storage Center The Center comprises of a 4,000 square feet data warehouse,located in Accra . This provides the local storage infrastructure forGNPC. The Center has a Geophysical Data Management Unit for storageof all geophysical data tapes and a Geological Data ManagementUnit for the storage of all geological data, including well cores andsampling data. The Geological Unit also has a Laboratory Facilityfor Geochemical, Petrographic and Paleontological DataAnalysis.

New Data Formats, technology and mode of transferis clearly stated in current PAs (PetroleumAgreements) These are up to date with currenttechnology, ie. 3592, 3592E, DVDs, andHard Drives.22

General challenges Seismic section films not digitized Reliability/Readability of somenew Data (QA/QC) Metadata missing Personnel (numbers, trainingetc.) ICT and Data Center in twoseparate locations.

DM Projects

GNPC Data Bank ProjectA Data Bank System has been proposed by GNPC forWorld Bank funding with support and technical assistanceprovided under a Norwegian OfD/NORAD collaboration.The Data Bank would constitute a three tier data integrationlayer made up of a cluster of data storage platforms andassociated software.

Integration Layer 1: Loaded Exploration andEngineering data currently in storage on tapes intoelectronic storage. Integration Layer 2: Scanning and storage of allhardcopy data including Library Reports, Maps,Image Captures of Cores and Sections, and otherBibliographic Materials, in agreed archival formats. Integration Layer 3: Production Database System,storing all Primary Aggregated Data to be receivedfrom GNPC’s producing fields for secure secondarystorage after validationThe Data Bank Common Data Administrator is toprovide a fully integrated management of the DataBank through a GIS Interface.

The Reference DatabaseProject The RDB is a repository of all metadata (culturaldata) of data in storage in GNPC. The Databaseis developed and will be linked to a portal toprovide open access to the general public andprospective investors on information to the datain storage.

DATABASE STRUCTURE Tables created and Normalized Good relationships between tables- Referential integrity Reference Tables and Lookups for easy data entry.

LOGIN SCREEN – ACCESS TO THEDATABASEThe login screen welcomes the user.Three (3) levels of access:1. Administrator;i. Information Maintenanceii. Query & Reportiii. User Account2. Co-Administrator;I. Information MaintenanceII. Query & Report3. Guest;Only Query & Report

MAIN INTERFACEThe former name of the reference database, “PETRO-PORT”,has been replaced with a more suitable name, “GNPCPUBLIC DATA PORTAL” (GNPC-PDP).This screen welcomes the user after successfully logging intothe database.

INTERFACE FOR INFORMATIONMAINTENANCEBy clicking the “Information Maintenance” button on the MainInterface, this Interface is displayed.The Information Maintenance interface gives you a menu thathelps you to Add, Edit and, if necessary, Delete data

INTERFACE FORLICENSESThe License Interface also displays the following sub-forms: LicenseContractor, License Partner (Both in a Tab Control) and License Area.

REPORTS

ONGOING WORKS & OUTSTANDING ISSUESONGOING WORKS: Data Entry for Wells is ongoing. Loading of Seismic data is also ongoing.- A “Runlist” had been developed to load data.- Documenting the seismic data loading procedure using“Runlist”.OUTSTANDING ISSUES: Interfacing the Reference database with GIS. The GISimplementation is to enable information from the RDB to be presentedin map form over the portal.
