The dataset was derived by the Bioregional Assessment Programme from a well completion reports dataset. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement. 


The dataset consists of shapefiles indicating the location and depth of well markers used to build the geological model for the Hunter subregion. The well markers show significant biological features in the rock formation that represent key indicators to the nature of the formation. Biomarkers are a group of compounds, primarily hydrocarbons, found in oils, rock extracts, recent sediment extracts, and soil extracts. When samples of oil and candidate source rocks are available, biomarkers can be used to make oil-source rock correlations which aid geologists in determining the age, history of and stratigraphy of the formations from drill logs and samples taken from various depths during the exploration phase.

## **Purpose** 

For display on HUN 2.12 geological figures (at the time of this metadata creation figures 002, 004 and 006)

## **Dataset History** 

Location data for the well sites and the biomarklers identified in this dataset has been sourced from well completion reports. The dataset has been exported from RMS geological modelling software as a .dat files. These have been converted to a shapefiles for the various wells and depths using ArcGIS.


The naming convention refers to the geological age and depth (TVD ss = total vertical depth subsea reported to the Australian Height Datum) of the various formations as follows:
