Seismic coverage 9800 km onshore 240 000 km 2 D 10 200 sq km 3 D offshore

Legislation Issues & Purpose • No Separate Oil & Gas Legislation • PASA established through Ministerial Directive in 1999 • M&PRD Act (2002) • Designated Agency responsible for – DATA MANAGEMENT: (NDR)- – – receive, maintain, archive, store, add value and provide access to data PROMOTION of Oil & Gas Exploration & Production REGULATION: Receive, process applications, Negotiate contracts & monitoring of work programs

Regulation towards Data… • • Data belongs to the State All New Data to be supplied to Agency – Field data after Survey – Regular reports /data/interpretations on completion thereof – Confidential for period of 4 years or till relinquishment • Available Data – To view in Data Room – Can be purchased – Is Provided to permit holders & Academic Institutions • All Data to be returned at Relinquishment

Business Model. . . • Funding – % of Oil and Gas Production – License Fees – Data Sales – Right to manage 3 rd Party data (Namcor) – From 2010 funded by Government

Data Standardization • Finder DM System is POSC Compliant • Reporting Guidelines approved by OPASA - Convention of line and well names Samples, reports and diagrams Seismic data Well data Formats – SEGD, SEGY, LIS, LAS, PDF and TIFF - Media – 3480, 3590, DLT, 8 mm Exabyte, DAT - WGS 84 Spheroid

Data Types. . . • Seismic Data – – – > 240 000 Km’s of 2 D > 10 000 km 2 of 3 D Field Data – 8 TB Near-line Processed & Reprocessed Seismic Data – 2 TB Project data in (SMT) - 500 GB • Well Data – – • • 311 Wells offshore & 193 Wells Onshore Geophysical Logs – 8. 5 TB G&G Well Reports and diagrams Samples, Cores and Slides Gravity and Magnetic Cultural Licensing Production Data

DB Project Data SMT EDRMS/ Laserfiche

Cost of Data. . . – Copy cost rates apply to permit holders and local academic institutions – Commercial tariffs apply to non permit holders • Technical Reports – dependent on cost and resources ( $100 to $800) • Well Log Data @ $ 1000/well • Seismic Processed Data @ $10/km • Seismic Field Data @ ( $6 to $12)/input tape

Projects. . . • Transcription of Seismic Data – Rescue data from old media – Reduce volumes – 80 000 – 9 trk tapes to 850 DLT Cart • Scanning of documents, maps, seismic sections & geophysical logs • Digitizing and conversion of seismic sections & geophysical logs • Onshore data gathering • EDRMS – Laserfiche with workflow functionality • Spatial Data Management and GIS

Problems • Sudden interest in onshore areas (CBM) and data not being accessed since 1970. • Support and maintenance of Data Management applications • Maintaining a quality set of metadata • Commitment from permit holders to supply data • Archiving of Project Data • Implementation of EDRMS is a tedious process and requires user buy-inn and careful planning

Successes • Good index and catalogue system • Availability of digital data – digitised and transcribed • Speedy delivery of quality data

Summary. . . • Well organised database and availability of digital data are key to success in marketing acreage • Use of a good EDRMS application are essential to good record keeping on all exploration activities
