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 3rd 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, 8mm Exabyte, DAT

- WGS84 Spheroid

Data Types...• Seismic Data

– > 240 000 Km’s of 2D– > 10 000 km2 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

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 Well organised database and availability of digital data are key to success indigital data are key to success inmarketing acreagemarketing acreage• Use of a good EDRMS application are essential Use of a good EDRMS application are essential to good record keeping on all exploration to good record keeping on all exploration activitiesactivities
