Data Quality

Lineage:Data was collated from various sources including petroleum operations records, NTGS records and databases, BMR (Bureau of Mineral Resources) publications, Geoscience Australia datasets and company information. The collated data were first published in MapInfo, ArcGIS and MS excel format in July 2010. Offshore wells, administered by NOPTA, were removed in 2012. Additional onshore wells and amendments to existing details are added routinely.

Positional Accuracy:Approximately +/- 20 metres for surveyed well locations. Location source varies from "original databases" to final well completion reports submitted by operators. Data entry and conversion from projected to geographic is manual. Datum has been assumed based on date if not given in original source.

Attribute Accuracy:Attribute source varies from "original database" to final well completion reports. The depths and elevations of some older wells have been converted from feet to meters.

Logical Consistency:The attributes and locations are manually entered and corrected if and when typing errors or more detailed information is found.

Completeness:Wells are added after the final well completion report has been submitted. Proposed and in-progress well details are not published in this dataset. Government (BMR and NTGS) stratigraphic wells are not included unless they were drilled as part of an industry government collaboration.

Data Dictionary

AttributeAttribute DescriptionPossible CodeCode Description
Basic StatusIndicates whether basic data is open file or not. The Petroleum Act Section 61 specifies when information provided to government can be made public (open filed).
BasinThe geological basin, sub-basin or province assigned to a well in the final Well Completion Report
Bottom hole Lithology/Formation Bottom hole lithology (BHL) or Bottom hole formation (BHF) - the lithology type or formation penetrated at total measured depth. Released when basic data is open filed.
ClassPost-drilling classification of well based on Lahee Well classification system. (Development, Extension, Miscellaneous, New field discovery, New pool discovery, New field wildcat, New pool wildcat, Service, Stratigraphic)
ContractorThe drilling contractor responsible for drilling the well
Drill RigName of drilling rig
Drilling DatumAbbreviation indicating the datum used as the baseline to measure drilling depths.DFDrill floor
GLGround level
KBKelly bushing
RTRotary Table
ENOUnique Entity Number (ENO) used to identify the well in Geoscience Australia databases
ElevationMeasurement in metres between the Drilling Datum and Elevation datum
Elevation DatumAbbreviation indicating elevation datum (Height datum).AHDAustralian Height Datum
LATLowest astronomical tide
MSLMean Sea Level
GL_WDThe elevation, in metres, of the ground level or the sea floor (water depth) with respect to Mean Sea Level. Only coastal offshore wells will have a sea floor elevation, and this will always be negative (- water depth)
Hydrocarbon ShowsIndicates whether the well had shows of hydrocarbons, and if so, the type and whether they were major or minor shows. Released when basic data is open filed.
Interp StatusIndicates whether interpreted data is open file or not. The Petroleum Act Section 61 specifies when information provided to government can be made public (open filed).
LatitudeLatitude of the well in decimal degrees using the GDA94 datum
LegislationAbbreviation indicating legislation governing the petroleum title, if applicableNANot applicable or unknown

Link to Report/sLink to Geoscience Exploration and Mining Information System (GEMIS) based on search for well name
LongitudeLongitude of the well given in decimal degrees using the GDA94 datum
On/Off ShoreIndicator of whether well is located onshore or nearshore within the 3 nautical mile limit i.e. Territory coastal waters (not Commonwealth waters)
OperatorThe operator of the title at the time the well was drilled. The operator is usually the company responsible for exploration/activities within the title area
PurposeIndicates the major purpose for the well as it was initially designed. (Appraisal, Development, Exploration, Extension-Appraisal, Stratigraphic)
Rig ModelType of drilling rig
Rig Release DateDate rig released
Side TrackIndicates whether well has a sidetrack or not. Released when basic data is open filed.
Spud DateDate drilling commenced
StatusOperational status of the well
Title IDThe petroleum permit or licence type and number at the time the well was drilled
Total Depth DateThe date when the total measured depth was reached. Released when basic data is open filed.
Total Measured DepthTotal depth in metres as measured by the drill string with respect to the drilling datum. Released when basic data is open filed.
Vertical DepthA theoretical maximum vertical depth in metres from the drilling datum. Released when basic data is open filed.
Well AliasAlternative well names published or commonly used
Well NameName according to the Department's naming convention
