Outline... Background Legislation Issues Business Model Data Issues –Standardization –Types –Systems –Projects –Access to Data –Cost of Data Successes Problems Lessons Learnt Summary
3
ACTIVITIES Offshore 3 Oil Fields & 1 Gas Field 2 Potential Gas field to be developed 9 Offshore permits granted 2 offshore areas available on licensing round Onshore Various potential CBM fields >100 Permits applied/granted Background SIZES 3000 km Coastline SA covers 1.2 million km 2 EEZ = 1.1million km 2 NOC=PetroSA NDR =Petroleum Agency SA Open License application system with formal license rounds from time to time
4
Karoo Basin South African basins prospective for oil and gas
5
Exploration wells 311 Offshore Wells 193 Onshore Wells Karoo Basin Bredasdorp Basin
6
Seismic coverage 9800 km onshore 240 000 km 2D 10 200 sq km 3D offshore
7
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
8
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
9
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
10
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, 8mm Exabyte, DAT -WGS84 Spheroid
11
Data Types... Seismic Data –> 240 000 Km’s of 2D –> 10 000 km 2 of 3D –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
12
Integrated Data Management System Direct PC Access Through Exceed Project Data Base SMT F i n d e r Master Index Forms / Reports & Catalogues ARCSDE & ARCGIS GeoDOC LogDB Log Archival RAM/VIDS Seismic Archival AssetDB Physical Inventory EDRMS/ Laserfiche Project Data SMT Populate Projects Store Results well seismic geology lease geopolitical map / grid production drilling financial Finder On-line Master & detail options
13
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
14
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
15
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
16
Successes Good index and catalogue system Availability of digital data – digitised and transcribed Speedy delivery of quality data
17
Summary... Well organised database and availability of digital data are key to success in 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 Use of a good EDRMS application are essential to good record keeping on all exploration activities
