The Impact

Derived from a larger scale project, which studied geomechanical issues associated with coal seam gas (CSG) production, this paper investigates a hypothetical case study based on the Latrobe Valley, Gippsland Basin, Victoria. The paper focuses on examining aquifer water management associated with CSG production-related water extraction. As such, the paper limits itself to determining the volume of water production from a hypothetical case study area in the Latrobe Valley. A simplistic property model and methane production strategy has been used. The impact of extraction of this water on the hydraulic head in aquifers underlying the produced seams is quantified. The Latrobe Valley Depression contains 129,000 million tonnes of coal resources and is one of the world’s largest, and lowest cost, energy sources. Most of Victoria’s electricity is generated using coal from the Loy Yang, Morwell and Yallourn mines. In addition to these massive operations, significant additional coal resources are available and unallocated at this time. Opportunities exist for the continued usage of these resources for electricity production, gasification, liquefaction and other coal conversion processes, as well as solid fuel for industrial, domestic and other uses. The existence of data from the Victorian Department of Primary Industries 2003 coal resource model was the main reason for the selection of the case study, and their data was used to form a model of the stratigraphy of the Latrobe Valley. Aquifer models were simulated in MODFLOW, based on extraction figures modelled in the CSG simulator COMET3.

Methane Utilization

According to situation of coal mine methane drainage and utilization, the five experienced development stages of coal mine methane drainage technology was summarized, the reasons of low rate of coal mine methane drainage were analyzed. Coal-seam methane utilization was analyzed from methane purification, methane generating electricity, chemical production, methane for civil utilization and utilization as automobile fuel etc. With the coal seam methane drainage quantity is more and more, the emissions requirements is more and more strict, so the emission reduction and effective utilization of this energy is important to accelerate efficient utilization of coal methane, reduce greenhouse gas emissions, protect environment, alleviate the supply contradiction of energy and realize sustainable development of coal mine etc.

Abstract Scarcity of research focusing on the evaluation of the coal seam methane pressure as a parameter determining the outburst risk makes it difficult to assess the value for which the level of this risk increases considerably. It is obvious that, apart from the gas factor, the evaluation of the threat should also take into account the strength factor. The research presented in this paper attempted at estimating the level of the outburst risk on the basis of the coal seam methane pressure value and firmness of coal. In this work, the author seeks to present both the relevant laboratory research and the measurements carried out in mines.

Sydney Gas Ltd (SGL) believes that the growth of the new and exciting coal seam methane (CSM) industry will certainly offer significant economic, social, and environmental benefits to the State of NSW within both the short and the long-term.This paper overviews SGL’s CSM resource development program for the Sydney Basin in general. SGL’s acreage provides an extensive contiguous coverage of the Sydney Basin, and is ideal as it straddles the main gas transmission line from Wollongong to Newcastle.Gas content is one of the most crucial parameters for CSM resource development. This paper also discusses the method adopted by SGL highlighting the pitfalls in the gas content measurements adopted by previous explorers that caused substantial under-estimation of the CSM resource in the Southern Sydney Basin. Gas content determination comprises three components, i.e. lost gas (Q1), desorbed gas (Q2) and residual gas (Q3). Evaluation of earlier data acquired under an ambient temperature rather than reservoir temperature, was the first source of error which resulted in under-estimating gas content calculation. Zero time for desorption measurements was previously set at core retrieval time rather than core cutting time generating an additional error. That is particularly significant in a highly stress-sensitive coal seam such as the Bulli which is the main target for the CSM resource development in the Southern Sydney Basin.This paper has also addressed the commercial case for developing CSM as a new energy source in NSW, for so long dependent upon coal and interstate gas.
