About this pilot

This open data portal is a pilot system featuring seismic and geochemistry data as the first release.

Data quality

As we publish our open data through this portal, you may encounter data quality issues. To help us improve data quality, please provide your feedback to GSQOpenData@dnrme.qld.gov.au

Geochemistry Data Notes

  • The Geochemistry pilot aims to test the concept of block-level geochemistry data compilation.
  • 7273 block-level compilations have been generated.
  • The original geochemistry Access database is compiled in AGD66, and has been transformed to GDA94 for this pilot.
  • The geochemistry data is a work-in-progress and the following issues are being addressed:
    • Laboratory libraries are partially linked to the assay results. At the moment, surface and drill hole geochemistry is linked to Lib_Job and Lib_Job An (Alias-Job) references only.
    • Data extraction enables the complete download of drill hole and associated files for the tenure block, which are linked to Lib_Job and Lib_Job An (Alias-Job) references only.
    • Data extracts from respective blocks are as individual packages, and are not concatenated into a single table for a data type.
    • Parameterised information have not been incorporated into the main data files.

Seismic Data Notes

  • Data and associated metadata for open-file petroleum seismic reflection surveys in Queensland.
  • Includes both 2D and 3D seismic surveys.
  • Currently 884 of approximately 1331 open-file surveys have been checked for completeness of both data and metadata and have been uploaded. The remaining surveys will be loaded progressively.
  • Additional surveys will be checked and uploaded in batches.
  • Metadata include reference to tenure, company reports and spatial information.
  • Data includes sections (scanned images of hard-copy plots), processed data (in SEGY format), field data (SEGY or SEGD) and support data.

Using the Open Data Portal

Data is published in units called a dataset - a parcel of data. For example, it could be a seismic survey or a geochemical dataset for a block.

When users search for data, the search results they see will be individual datasets.

A dataset contains two things:

  • Information or metadata about the data. For example, the title, description, date, etc.
  • Resources which hold the data itself. A resource can be CSV or Excel, XML, PDF, image file, linked data in RDF format, etc. A dataset can contain any number of resources.

Registering and logging in

Registration is not required to search and download data.

However, you may register so that you can use the "Follow" a dataset functionality.

To register, click the Register link at the top right of any page.

Simple search

Search for a single term such as relinquishment or Northwest.

Search for a phrase using a group of words surrounded by double quotes such as "well completion report".

Multiple terms can be combined together with Boolean operators to form a more complex query (see below).

Advanced search

Field search

You can search any field by typing the field name followed by a colon ":" and then the term you are looking for. As an example, if you want to search the title and the description field, you can enter:

title:Cloncurry AND text:”radiometric survey”


title:”Super Isa Basin” AND “well completion report”

Note: Since text is the default field, the field indicator is not required.

Wildcard Searches

To perform a single character wildcard search use the "?" symbol.

To perform a multiple character wildcard search use the "*" symbol.

The single character wildcard search looks for terms that match that with the single character replaced. For example, to search for "text" or "test" you can use the search: te?t

Multiple character wildcard searches looks for 0 or more characters. For example, to search for test, tests or tester, you can use the search:


You can also use the wildcard searches in the middle of a term.


Note: You cannot use a * or ? symbol as the first character of a search.

Fuzzy Searches

To do a fuzzy search use the tilde, "~", symbol at the end of a Single word Term. For example to search for a term similar in spelling to "roam" use the fuzzy search:


This search will find terms like foam and roams.

Proximity Searches

Lucene supports finding words are a within a specific distance away. To do a proximity search use the tilde, "~", symbol at the end of a Phrase. For example to search for a "apache" and "jakarta" within 10 words of each other in a document use the search:

"jakarta apache"~10

Range Searches

Range Queries allow one to match documents whose field(s) values are between the lower and upper bound specified by the Range Query. Range Queries can be inclusive or exclusive of the upper and lower bounds. Sorting is done lexicographically.

mod_date:[20020101 TO 20030101]

This will find documents whose mod_date fields have values between 20020101 and 20030101, inclusive. Note that Range Queries are not reserved for date fields. You could also use range queries with non-date fields:

title:{Adavale TO Camooweal}

This will find all documents whose titles are between Aida and Carmen, but not including Aida and Carmen.

Inclusive range queries are denoted by square brackets. Exclusive range queries are denoted by curly brackets.

Boosting a Term

Lucene provides the relevance level of matching documents based on the terms found. To boost a term use the caret, "^", symbol with a boost factor (a number) at the end of the term you are searching. The higher the boost factor, the more relevant the term will be.

Boosting allows you to control the relevance of a document by boosting its term. For example, if you are searching for

jakarta apache

and you want the term "jakarta" to be more relevant boost it using the ^ symbol along with the boost factor next to the term. You would type:

jakarta^4 apache

This will make documents with the term jakarta appear more relevant. You can also boost Phrase Terms as in the example:

"jakarta apache"^4 "Apache Lucene"

By default, the boost factor is 1. Although the boost factor must be positive, it can be less than 1 (e.g. 0.2)

Boolean Operators

Boolean operators allow terms to be combined through logic operators. Lucene supports AND, "+", OR, NOT and "-" as Boolean operators(Note: Boolean operators must be ALL CAPS).

The OR operator is the default conjunction operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms exist in a document. This is equivalent to a union using sets. The symbol || can be used in place of the word OR.

To search for documents that contain either "jakarta apache" or just "jakarta" use the query:

"jakarta apache" jakarta


"jakarta apache" OR jakarta


The AND operator matches documents where both terms exist anywhere in the text of a single document. This is equivalent to an intersection using sets. The symbol && can be used in place of the word AND.

To search for documents that contain "jakarta apache" and "Apache Lucene" use the query:

"jakarta apache" AND "Apache Lucene"


The "+" or required operator requires that the term after the "+" symbol exist somewhere in a the field of a single document.

To search for documents that must contain "jakarta" and may contain "lucene" use the query:

+jakarta lucene


The NOT operator excludes documents that contain the term after NOT. This is equivalent to a difference using sets. The symbol ! can be used in place of the word NOT.

To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query:

"jakarta apache" NOT "Apache Lucene"

Note: The NOT operator cannot be used with just one term. For example, the following search will return no results:

NOT "jakarta apache"

- The "-" or prohibit operator excludes documents that contain the term after the "-" symbol.

To search for documents that contain "jakarta apache" but not "Apache Lucene" use the query:

"jakarta apache" -"Apache Lucene"


Lucene supports using parentheses to group clauses to form sub queries. This can be very useful if you want to control the boolean logic for a query.

To search for either "jakarta" or "apache" and "website" use the query:

(jakarta OR apache) AND website

This eliminates any confusion and makes sure you that website must exist and either term jakarta or apache may exist.

Field Grouping

Lucene supports using parentheses to group multiple clauses to a single field.

To search for a title that contains both the word "return" and the phrase "pink panther" use the query:

title:(+return +"pink panther")

Escaping Special Characters

Lucene supports escaping special characters that are part of the query syntax. The current list special characters are

+ - && || ! ( ) { } [ ] ^ " ~ * ? : \

To escape these character use the \ before the character. For example to search for (1+1):2 use the query:



The open data portal provides an API for developers who want to write code that interacts with the open data portal.

CKAN’s Action API is a powerful, RPC-style API that exposes all of CKAN’s core features to API clients. All of a CKAN website’s core functionality (everything you can do with the web interface and more) can be used by external code that calls the CKAN API. See the user guide at:
