Unconventional Gas in Western Australia
What is Unconventional Gas?
Natural gas is found in a number of different geological environments. As demand for gas has increased and drilling and extraction technology has improved, so exploration and production is moving into geological environments that were previously too challenging; gas in such locations is called Uncoventional Gas and it is often described based on the type of rock from which it is extracted (Figure 1), such as:
• coal seam gas (CSG) – found in coal seams,
• tight gas – found in compacted sandstone or limestone and
• shale gas – found in dense shale rock. Read more

Operational Value from Compliance Reviews
Periodic compliance reporting is one of the conditions of many groundwater abstraction licences. Typically, compliance reports include the volume of groundwater abstracted, the resulting effect on groundwater levels, groundwater quality and a comparison of these against licensed conditions. In Western Australia, for example, reporting requirements are outlined in the Department of Water’s Operational Policy No.5.12 and they have variously been called Wellfield Assessments, Annual Aquifer Reviews and Groundwater Monitoring Reports.
However, over and beyond maintaining an abstraction licence or a component of social licence, there is often the opportunity to use a compliance review to add operational value. We believe there is often the opportunity to review the data from an operational perspective with potential benefits for costs and risk management. Read more
