Glossary
See explanations and information about key terms, measurements and acronyms used by the sector:
| Bcf | Billion Cubic Feet (of gas) |
|---|---|
| Boe | Barrels of Oil Equivalent. The barrel of oil equivalent (BOE) is a unit of energy approximate equal to the energy released by burning one barrel (158.9873 litres) of crude oil. |
| CO2-e | Carbon dioxide equivalent |
| CSG | Coal seam gas |
| FEED | Front End Engineering and Design. The FEED is a decision point in an LNG project and covers the basic engineering after the conceptual study. The FEED design focuses on the technical requirements of a project. |
| GA | Geoscience Australia. |
| Hydrocarbons | Organic compounds consisting entirely of hydrogen and carbon. Hydrocarbons are the principal constituents of oil and natural gas. |
| LNG | Liquefied natural gas |
| Methane | Primary component of Natural gas. Methane is a Hydrocarbon, which is a family of molecules consisting entirely of hydrogen and carbon. Methane is one carbon molecule surrounded by four hydrogen molecules (CH4). |
| Mtpa | Million tonnes per annum (of LNG) |
| PRRT | Petroleum resource rent tax |
| Permeability | The degree to which gas or fluids can move through a porous material, such as rocks. |
| Petroleum | Liquid, gaseous and solid hydrocarbons, including oil, natural gas, gas condensate, ethane, propane, butane and pentane. |
| Plugged and abandoned | When all the reservoir and hihg-pressure zones in a well are sealed with cement so that no fluid can escape. |
| Proven and probable reserves (2P) | Proven reserves plus reserves that are deemed probable (at least 50 per cent likely) to be commercially recoverable. Also known as 2P or P50 reserves. |
| Proven reserves (1P) | Quantities of petroleum that can be estimated with reasonable certainty (at least 90 per cent) to be commercially recoverable. Also known as 1P or P90 reserves. |
| Proven, probable and possible reserves (3P) | Proven and probable reserves plus reserves that are deemed possible (at least 10 per cent likely) to be commercially recoverable. Also known as 3P or P10 reserves. |
| RET | Renewable energy target |
| Reservoir | A rock or geological formation that holds petroleum within the pore spaces between individual grains. |
| TCF | Trillion cubic feet (of natural gas) |
