  • 1. Strategies to ensure environmental compliance in CSG projects Q&A with Chris Hogle, Reliance Industries Coal Seam Gas Water Management 2011Where does Coal Seam Gas fit in as a green energy source?Coal Seam Gas is methane which is extremely clean burning; thereforehave lower greenhouse gas emissions than petrol or diesel fuels. RecoveringCoal Seam Gas from coal seams reduces the chance of methane emissionswhich can cause green house gases if the gas is allowed to seep to thesurface and into the atmosphere.How do you see the shape of your industry changing over the next fewyears?I see this industry growing tremendously not only in Australia but around theworld as the continued growth and demand for natural gas continues to riseannually. In the US and Canada, Coal Seam Gas has already contributedsignificantly to the shortfall of gas production from conventional oil and gasfields to help reduce import of natural gas for the nation. Around the globewith energy prices on the rise, Coal Seam Gas also provides for a good rateof return for the operators, who in turn have stimulated these investments inthe recent years.What strategies do you have in place to ensure environmentalcompliance in your CSG projects?Environmental Compliance for Coal Seam Gas is much easier thanconventional Oil and Gas development. The only discharge is water andmany times, this water is potable, thus making the impact minimal. If thewater is brine it often is only very slight and can be treated in many ways tomake it useful for agriculture, drinking, fish farming, creating habitat for wildfowl, etc. Environmental Compliance is a top priority for all employees in theenergy business along with safety. There is a whole team dedicated to seeand insure all practices are best practices and insuring compliance with thelocal, state, and national regulations. 1
  • 2. How does Reliance Infrastructure develop suitable plans for water andbrine management?Water management planning has to take into account the water quality first todetermine the best practice for the development. It varies widely from basinto basin. The water requirements of the local population are a critical factorfor water management planning. Generally we try to reinject the water ifpossible as it will remain a resource for future generations and there is nosurface impact.With so many water treatment systems and technologies in the market,how do you determine the appropriate solutions for your projects?Water management is a high capital expense for operators and it is all drivenby economics. The system that can deliver and meet the national waterquality standard (and at the lowest cost) determines the system that will beused.Some of Reliance Infrastructure’s projects involve the re-injection ofcoal seam water - what are the cornerstones to best practice here?The re-injection or often not produced water to surface is often solutions inCoal Seam Gas overlooked by many operators. You can re-inject back into acoal seam (just not the one you’re producing from) as in many basins the gasis produced from several seams. You can inject the water without everbringing the water to surface if the well design using most any kind of artificiallift system. These coal seams often have inter-bedded permeable sandstoneswith similar water quality and these to can be used for injection. The key isthe geology of the basin and where do the potential injection horizons occur inthe well-bore.Chris Hogle will be speaking at the Coal Seam Gas Water ManagementConference 2011 and will be presenting an international case study.
