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

Attribute Attribute Description Possible Code Code Description

Basic Status Indicates 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).

Basin The 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.

Class Post-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)

Contractor The drilling contractor responsible for drilling the well

Drill Rig Name of drilling rig

Drilling Datum Abbreviation indicating the datum used as the baseline to measure drilling depths. DF Drill floor

GL Ground level

KB Kelly bushing

RT Rotary Table

UNK Unknown

ENO Unique Entity Number (ENO) used to identify the well in Geoscience Australia databases

Elevation Measurement in metres between the Drilling Datum and Elevation datum

Elevation Datum Abbreviation indicating elevation datum (Height datum). AHD Australian Height Datum

LAT Lowest astronomical tide

MSL Mean Sea Level

UNK Unknown

GL_WD The 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 Shows Indicates 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 Status Indicates 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).

Latitude Latitude of the well in decimal degrees using the GDA94 datum

Legislation Abbreviation indicating legislation governing the petroleum title, if applicable NA Not applicable or unknown

PA 1984 Petroleum Act 1984

PPMA 1980 Petroleum (Prospecting and Mining) Act 1980

PSLA 1981 NT Petroleum (Submerged Lands) Act 1981

Link to Report/s Link to Geoscience Exploration and Mining Information System (GEMIS) based on search for well name

Longitude Longitude of the well given in decimal degrees using the GDA94 datum

On/Off Shore Indicator of whether well is located onshore or nearshore within the 3 nautical mile limit i.e. Territory coastal waters (not Commonwealth waters)

Operator The 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

Purpose Indicates the major purpose for the well as it was initially designed. (Appraisal, Development, Exploration, Extension-Appraisal, Stratigraphic)

Rig Model Type of drilling rig

Rig Release Date Date rig released

Side Track Indicates whether well has a sidetrack or not. Released when basic data is open filed.

Spud Date Date drilling commenced

Status Operational status of the well

Title ID The petroleum permit or licence type and number at the time the well was drilled

Total Depth Date The date when the total measured depth was reached. Released when basic data is open filed.

Total Measured Depth Total depth in metres as measured by the drill string with respect to the drilling datum. Released when basic data is open filed.

Vertical Depth A theoretical maximum vertical depth in metres from the drilling datum. Released when basic data is open filed.

Well Alias Alternative well names published or commonly used
