NSW Petroleum Boreholes 20140815

Abstract

This dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.

The Petroleum Wells database stores information about petroleum wells within NSW. The NSW Petroleum Wells Database has been developed to record summary data on petroleum exploration and development drilling data for holes drilled in New South Wales. The database contains summary information about each drillhole such as location, total depth, azimuth/dip, geochemistry, wireline logs and DIGS references.

Full metadata available at: http://minview.minerals.nsw.gov.au/mv2web/mv2?cmd=MDDetail&lid=petbore

This dataset has been provided to the BA Programme for use within the programme only. Third parties should contact the NSW Department of Industry. http://www.industry.nsw.gov.au/

Dataset History

Data Quality

Lineage:

The primary data source for the petroleum borehole database was company exploration reports supplied to the Department of Mineral Resources as part of the statutory reporting requirements for exploration licences. Holes drilled by Industry and Investment NSW (Minerals) are also included in the database. Initially data was held in the COGENT Oracle database. The data was exported into spreadsheets and maintained in this environment for some time. The database is now on a SQL Server platform. Data can be entered or edited using the GBIS program

Positional Accuracy:

Drillhole coordinates have been obtained from a number of sources including exploration companies and consultants. The accuracy of the drillholes varies and is often unknown. In most instances the drillhole coordinates have been measured off company exploration maps or parish/county maps and these holes have an accuracy of between 25m and 500m depending on the quality of the map displaying the holes. Where a number of holes have been drilled on one prospect they will be located accurate relative to each other.

Attribute Accuracy:

The dataset contains a number of attributes (see attribute definitions below), these values have been derived from a large number of sources (see data lineage). Overall accuracy of the attributes will vary according to many factors such as the company that reported the drillhole and the type of lease the hole was drilled on. Some companies provide the Department with exploration reports of very high standard while others submit the bare minimum of information. Likewise, exploration licences (EL's) have fairly stringent reporting requirements while older types of licences and mining leases often have reports of poor quality

Logical Consistency:

There should be a high degree of logical consistency in this data set as data from one drillhole does not depend upon other information

Completeness:

As mentioned in the attribute accuracy the completeness of the data is dependent upon the quality of the data supplied to the Department in company reports. It is not always possible to obtain all the information required for each drillhole.
