“…An injection test consists in injecting, rather than producing, a fluid in a potential reservoir zone and in monitoring the pressure response. Except for fluid sampling, injection tests can provide the same information as conventional tests [44,45]. This methodology is easily applied to UGS because gas injection is the very essence of gas storage and the critical issues that can arise when injecting a fluid which is immiscible with the reservoir fluid are removed [46].…”

Abstract:The development of an underground gas storage (UGS) project and its subsequent management must ensure technical feasibility, commercial value and long-term efficiency. The UGS industry has borrowed much of its knowledge from other disciplines (primarily oil and gas reservoir engineering), but it has also developed its own technology. This paper provides a methodological approach based on current practices and available methods for designing and safely operating a UGS (including the so-called "delta-pressure" option to enhance UGS performance) and highlights what is special in UGS compared to oil and gas reservoirs.

“…An injection test substantially consists in injecting a fluid, commonly a brine, diesel or nitrogen, in a potential reservoir zone and in monitoring the pressure response. The combined analysis of the injected rate and pressure variations can provide all the information needed to estimate the well productivity (Gunawan Gan et al, 2002;Verga et al, 2011Verga et al, , 2012. The drawback of injection tests is that fluid sampling is not possible.…”

Purpose – The purpose of this paper is to describe the ongoing shift in sustainable engineering and the approaches used by universities for engineering students. At the United Nations Earth Summit, in Rio de Janeiro, in 1992, participating nations agreed to work together to achieve the goal of sustainable development. Twenty years on, great progress has been made, but many challenges remain and overcoming them and ensuring a sustainable future will require the knowledge, skills and input of engineering professionals. Ethics and costs have long been part of engineering, but broader understanding is now needed because the skill set those engineers will need has grown dramatically. Design/methodology/approach – In this paper, the authors describe the ongoing shift to sustainable engineering and discuss a variety of approaches that universities are currently using to introduce engineering students and practitioners to sustainability principles and practice and how those can be utilized in mining and petroleum high education institutions. Findings – The authors first place sustainability in an engineering context and vice versa, and then review alternative approaches to incorporating sustainability in engineering curricula, briefly highlighting a few key concepts and documenting an example. Research limitations/implications – The authors first place sustainability in an engineering context and then review alternative approaches to incorporating sustainability in engineering curricula, briefly highlighting a few key concepts and documenting an example. Originality/value – The challenge to educators is to ensure that new concepts addressing sustainability are not only instilled in the next generation of engineers but are also being communicated to practicing engineers. Incorporating sustainability into mining and petroleum engineering education is identified as a way to engage students, encourage their enthusiasm and interest them in pursuing engineering as a career that is not only interesting but also contributes to society. Distance education is identified as a way to education practicing engineers about sustainability concepts.
