Description

Abstract:

This metadata entry is for the following shape files, found in the 'exploration' directory on the CDROM:

wells.shp:

Reference system for petroleum exploration and development wells drilled in Australia. Taken from the AGSO database called 'PEDIN".

samples.shp

This is general point locations for where seabed samples have been collected over the years by AGSO. Each sample has been collected by AGSO Rig Seismic Surveys.

Data quality

Lineage:

wells - This data is extracted from Well Completion Reports and other scouting methods, they were then all loaded into the Oracle database 'PEDEN' by AGSO staff. The point data was exported from the AGSO Oracle database and then imported into ARCVIEW shape files. No modifications were required.

samples - The seabed samples were collected by BMR in the mid 1960's and the results were listed in the BMR Bulletin 83, (appendices A to D). The data was then keyed into excel spreadsheets in 1999 by Ian Lavering and converted to ARCVIEW shape files.

Positional accuracy:

wells - Accuracy could be greater than 500m. For older wells where Geodetic datum not available. It can not be none what projection the wells are in.

samples - The seabed sample locations are indicative only and no additional attempt has been made to check or modify the listing from the BMR Bulletin 83.

Attribute accuracy:

wells - HIGH

All the attribute data has been entered in by AGSO staff and has a high attribute of accuracy.

samples - HIGH

The sample points give a general indication of material on the seabed in the vicinity of the indicated sample point, all values are in percentages.

Logical Consistency:

No logical consistency is documented.

Completeness:

All vector data and details are complete and verified.
