HUN RMS Output Dat Files v01

Abstract

The dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are 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 contains the raw .dat versions of the structural geological model for the Hunter subregion. RMS geomodelling was used to construct the geological model for the Hunter subregion. The data set contains the depth to basement horizons, reference horizons, eroded horizons, isochores and well markers extracted from the completed geological model. The model was built using data extracted from well completions reports published by mining companies and consultants, which record the depth of various formations encountered during drilling works. These data were compiled into model input files (See data set: Hunter deep well completion reports - f2df86d5-6749-48c7-a445-d60067109f08) used to build the RMS model.

Nine geological formations and their depths from the surface are included covering a grid across the Basin. The geological model is based on measured depths recorded in well completion reports published by mining companies and consultancies.

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:

Regional horizon name Age (geological stage) Newcastle Coalfield Hunter Coalfield Western Coalfield Central or Southern coalfields

M600 Top Anisian Top Hawkesbury Sandstone Top Hawkesbury Sandstone Top Hawkesbury Sandstone Base Wianamatta Group

with 'M' referring to Mesozoic and 'P' to Paleozoic

Dataset History

RMS geomodelling was used to construct the geological model for the Hunter subregion. The data set contains the layers in the completed geological model. The model was built using data extracted from well completions reports published by mining companies and consultants which record the depth of various formations encountered during drilling works. These data were compiled into model input files (See dataset: Hunter deep well completion reports - f2df86d5-6749-48c7-a445-d60067109f08) used to build the RMS model.

This model has a horizontal resolution of 2000 x 2000 m (x y), with 109 vertical layers for a total of 511,118 cells. The depth ranges between 1185m above sea level and 5062 m below sea level.

Data originally sourced from 44 well completion reports and incorporated into the geological model. The reference horizons were exported from RMS software as .dat files.
