bearing the dissolved ore content is then pumped to the surface and processed. This process allows the extraction of metals without the need for mining. The goal of this project is to understand the mechanisms of minerals in-situ leaching and to examine the ways how to enhance the extraction efficiency. This goal can be achieved through (1) development of a mineral dissolution model for minerals; (2) simulation of solution flow in ore deposits; (3) evaluation of stimulation techniques; and (4) assessment of environmental risks. Liu, Jishan, Professor Extraction of Unconventional Gases Disciplines: Oil & Gas, Petroleum Prerequisite skills: Knowledge of flow in porous media and modelling skills are desirable. The cost-effective horizontal drilling and hydraulic fracturing technologies, along with the implementation of protective environmental management practices, have enabled the commercial production of gas from previously unproductive gas reservoirs including shale gas, coal seal gas and tight sand gas. The goal of this project is to examine what factors affect the gas production rate and how they can be controlled in-situ. This goal can be achieved through application of a simulation tool to examine the following factors: (1) gas desorption induced shale deformation; (2) hydraulic fracture density; (3) rock micro-structures; and (4) in-situ stresses. Johns, Mike, Professor & May, Eric, Professor Carbon Sequestration Suitability: Chemical Engineering, Mechanical Engineering, Mechanical Engineering (Oil and Gas Major) Western Australia has several major offshore gas assets containing significant quantities of carbon dioxide. Scenarios for dealing with this CO2 must be developed before these gas fields can be developed. One scenario involves the re-injection of carbon dioxide produced from one reservoir into the extremities of a different natural reservoir for the purpose of both CO2 disposal and enhanced gas recovery. However, such a strategy is only viable if the probability of breakthrough by the re-injected CO2 to the producing wells is small. Simulating reliably this novel reservoir production scenario requires an improvement in our fundamental understanding of the hydrodynamic behaviour of supercritical CO2 in heterogeneous gas and water-saturated rock. Research projects are available measuring this behaviour as well as its inclusion into relevant field simulations.
