The Chevron-Shell-ExxonMobil Gorgon Project will store CO2Carbon dioxide resulting from the production of natural gasGas stored underground; It consists largely of methane, but can also contain other hydrocarbons, water, hydrogen sulphide and carbon dioxide, these other substances are separated before the methane is put into a pipeline or tanker in the Greater Gorgon area fields (coast of Western Australia). On September 14, 2009, Chevron Australia and its Foundation Participants, ExxonMobil and Shell announced a Final Investment Decision on the Gorgon Project. In August 2009 the Gorgon Project also completed its environmental assessment process. The environmental approvals were the result of 6 years of preparation, including the research and contributions of numerous independent experts and extensive community consultation. The EIS (Environmental Impact Statement) completed in May 2006 details the riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event process used as wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injection of fluids as its results. The environmental riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event process has evaluated the likelihood (using a qualitative scoring system) and consequences of adverse environmental impacts. Potential risks and environmental consequences were identified by technical experts in a broad range of fields through a series of workshops. Some deterministic "what if" scenarios as wellManmade hole drilled into the earth to produce liquids or gases, or to allow the injection of fluids as a probabilistic approach were taken with respect to managing uncertainties associated with CO2Carbon dioxide storage(CO2) A process for retaining captured CO2, so that it does not reach the atmosphere, including identifying, evaluating, and generating options for managing subsurface risks. Extensive monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions activities are planned to manage and reduce uncertainty associated with CO2Carbon dioxide injectionThe process of using pressure to force fluids down wells / storage(CO2) A process for retaining captured CO2, so that it does not reach the atmosphere activities. A plan has been proposed to manage events such as unpredicted migrationThe movement of fluids in reservoir rocks of the CO2Carbon dioxide, unacceptable formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it pressures, corrosion of pipelines and wells, and others. The probability of CO2Carbon dioxide migrating to the surface has been determined to be remote. Studies of the area have determined that the containmentRestriction of the movement of a fluid to a designated volume (e.g. reservoir) riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event (riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event of containmentRestriction of the movement of a fluid to a designated volume (e.g. reservoir) failure) is extremely low, and unacceptable riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event associated with CO2Carbon dioxide storage(CO2) A process for retaining captured CO2, so that it does not reach the atmosphere at any point would likely result in venting of the CO2Carbon dioxide to the atmosphereThe layer of gases surrounding the earth; the gases are mainly nitrogen (78%) and oxygen (around 21%). Potential impacts on the project were evaluated in terms of: health, safety, and environmental issues; containmentRestriction of the movement of a fluid to a designated volume (e.g. reservoir); monitoringMeasurement and surveillance activities necessary for ensuring safe and reliable operation of a CGS project (storage integrity), and for estimating emission reductions and verification(CO2 storage) The proof, to a standard still to be decided, of the CO2 storage using monitoring results; (in the context of CDM) The independent review by a designated operational entity of monitored reductions in anthropogenic emissions; injectivityA measure of the rate at which a quantity of fluid can be injected into a well; capacity; riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event to hydrocarbon / other assets; cost. Responses to these potential impacts (such as using relief wells, if necessary, to release formationA body of rock of considerable extent with distinctive characteristics that allow geologists to map, describe, and name it pressure and mitigate the riskConcept that denotes the product of the probability of a hazard and the subsequent consequence of the associated event of migrationThe movement of fluids in reservoir rocks along faults or fractures) were developed and are described in the EIS (CSLF, 20092009 - CSLFPhase I Final Report from CSLF Risk Assessment Task Forcesee more; Chevron Australia Pty Ltd, 20062006 - Chevron Australia Pty LtdFinal Environmental Impact Assessment / Response to Submissions on the Environmental Review and Management Programme for the Proposed Gorgon Developmentsee more; http://www.chevronaustralia.COm/ ourbusinesses/gorgon.aspx).
