The combustion of fossil fuels causes the emission of greenhouse gases such as C02, methane and NOx. The use of natural gas in place of oil and coal can help indeed to reduce greenhouse gases emission because natural gas is the cleanest of fossil fuels. Its non-pollutant character offers it extremely favourable prospects. World consumption is bound to increase rapidly, from 2120 Bern in 1991 to 3100-3500 Bern in 2010. Expanding world output will not raise any problems of resources because natural gas is an abundant energy source. However, gas production and transport costs are going to rise due to increasing distances between main gas reserves and consumer markets. The financial constraints will be the major factor limiting the growth in natural gas trade. And new solutions would have to be found in order to implement today the projects required in the long-term.

Northeastern B.C. has several trillion cubic feet of established gas reserve and estimates of ultimate potential are as high as 50 tcf. Westcoast's current deliverability of 1.9 bcf/d is expected to rise by 30% over the next five years. Through-put on Westcoast's pipeline system reached 0.5 bcf/d in 1992. The new role of natural gas in the energy mix will lead to greater consumption such as in gas-fired cogeneration. The price will be “right” when supply and demand are evenly balanced.

This study explores the international natural gas market integration using the Engle–Granger cointegration and error correction model. Previous studies have suggested that liquefied natural gas (LNG) and oil-linked pricing with a long-term contract have played key roles in gas market integration, especially between European and Asian markets. There is, however, little discussion of the role of the emergence of a swing supplier. A swing supplier, e.g., Qatar or Russia, is flexible to unexpected changes in supply and demand in both European and Asian markets and adapts the gas production/exports swiftly to meet the changes in the markets. Qatar has been a swing supplier since 2005 in the global natural gas market. In 2009, Qatar’s global LNG export share reached above 30% and has remained around 25% since then. Empirical results indirectly support that the emergence of a swing supplier may tighten market integration between Europe and Asia. The swing supplier may have accelerated the degree of market integration as well, particularly after 2009.

The carbon-free future should not be confused with a utopian future. A zero-carbon world will include the difficult realities experienced in Texas in February 2021. As shown in a graph of US EIA data, during the recent extreme cold event in Texas, wind and solar could not hold flat compared with their baseline the week before (4–8 February). Coal and nuclear remained mostly steady, while natural-gas producers ramped up supplies delivered to power plants by a factor of 4, helping people who were struggling to heat their homes. Natural gas may not receive well-deserved recognition from some quarters, and blackouts and loss of life still occurred, but our industry stepped up when people needed us most. Texas generates 25% of the wind power in the US and has more solar potential than 18 northern states combined, yet wind and solar simply failed when called upon. As the world attempts to go carbon-free, this reviewer hopes that more consumers will see the difference between results and public-relations promises. It will take a legitimate technological step-change before an unsubsidized renewable energy source is capable of replacing reliable fossil fuels. Imagine if Sir Isaac Newton, with all his brilliance, had tried to be the first man to land on the moon. In 1720, the cumulative knowledge did not exist to allow that to happen, and, if he had tried, he could have spent the entire British treasury and still failed. By standing upon the shoulders of giants like Newton, others were able to reach the moon 250 years later. Step-change technological breakthroughs happen when their time has come, not when mandated by political pressure. Until you hear that commercial fusion reactors are online or that low-cost, grid-scale electricity storage made from commonplace materials can handle a 10-day cold snap or heat wave, there is no need to hang up your pipe wrenches. Fossil fuels will remain the most energy-dense, cost-effective, reliable energy source until an extraordinary breakthrough creates a better alternative. The three papers selected for this feature demonstrate the continued critical role of gas production, and innovation therein, in the necessary daily role of supplying the world’s energy needs. One discusses means of exploiting stranded offshore gas reservoirs; the second details an Eagle Ford cyclic-gas-injection enhanced-oil-recovery effort; and the third focuses on the fracturing interference of multi-well pads in shale gas reservoirs.

The global warming which preoccupies humanity, is still considered to be linked to a single cause which is the emission of greenhouse gases, CO2 in particular. In this article, we try to show that, on the one hand, the greenhouse effect (the radiative imprisonment to use the scientific term) took place in conjunction with the infrared radiation emitted by the earth. The surplus of CO2 due to the combustion of fossil fuels, but also the surplus of infrared emissions from artificialized soils contribute together or each separately,  to the imbalance of the natural greenhouse effect and the trend of global warming. In addition, another actor acting directly and instantaneously on the warming of the ambient air is the heat released by fossil fuels estimated at 17415.1010 kWh / year inducing a rise in temperature of 0.122 ° C, or 12.2 ° C / century.

This paper presents a case study of a natural gas production site covering various technical issues related to selection of an appropriate Reverse Osmosis (RO) system. The long-term field experience indicates the necessity of the selection of appropriate pretreatment systems for fouling-free RO operational conditions. The produced water has a variety of impurities such as oil and grease, process chemicals used for corrosion and scaling control, and dehydration of natural gas, etc. This situation leads to a complicated and extremely difficult task for a membrane specialist to design RO systems, especially the pre-treatment section. Here as part of the pretreatment selection, two types of UF membrane modules viz. spiral wound and hollow fibre, with MWCO of 8000 and 50,000 Dalton respectively, were tested in parallel with NF membranes of the spiral wound type with MWCO 200 Dalton. The UF permeate is used as feed for RO compatibility testing. Both configurations of UF failed to be compatible, due to irreversible fouling of the RO membrane. The NF membrane, however, showed interesting results, due to membrane stability in terms of cleaning and fouling. The NF plant with 50% capacity gave a recovery of 75% and the RO plant gave a recovery of 60% versus the expected 92–95%. The long-term tests have indicated that the reminder of the membranes could be installed to achieve full capacity of the plant. This study also demonstrates the importance of selection of proper pre-treatment set-up for the RO system design.

In many parts of the world, drinking water is not available except through desalination. Most of these areas have an abundance of solar energy, with few cloudy periods. Energy is required for desalination and for producing electricity. Traditionally this energy has been supplied by fossil fuels. However, even in those parts of the world that have abundant fossil fuels, using them for these purposes is being discouraged for two reasons: 1) the emission of greenhouse gases from combustion of fossil fuels, and 2) the higher value of fossil fuels when used for transportation. Nuclear power and solar power are both proposed as replacements for fossil fuels in these locations. Both of these energy systems have high capital costs, and negligible fuel costs (zero for solar) Instead of these two primary forms of energy competing, this paper shows how they can compliment each other, especially where a significant part of the electricity demand is used for desalination.

The COVID-19 pandemic appeared in the midst of developing the European Green Deal, the most ambitious project to decarbonise the EU’s economy to date. Among other issues, the project highlighted the challenges connected to the long-term role of natural gas as a fossil fuel in the European economy. Moreover, the changes to the gas architecture caused by the development of new import infrastructure (especially Nord Stream and its extension, which is currently under construction) put additional pressure on the transit countries, mainly of which are linked to the Brotherhood pipeline. These have been strong supporters of natural gas utilisation and harsh critics of new pipelines that circumvent their territories, as they consider energy transit to be an important part of their energy sectors. This research examines the political discourse on gas transit in Slovakia and Ukraine in order to identify the main arguments connected to these positions. The paper examines a total of 233 textual units from both countries for the period 2014–2018. It concludes that, while Ukraine sees transit predominantly through the lens of cooperation with the EU and other actors, the Slovak political discourse considers gas transit in terms of energy security and the availability of gas for the national economy.

As the preferred 'growth fuel' at the turn of the millennium, natural gas carries a great weight of expectations. Globally, it offers a partial solution to the problem of greenhouse gas emissions as a substitute for other fossil fuels, while at the same time reducing the security risks attached to dependence on oil by providing greater diversity of energy supply. Regionally, it is envisaged as the 'clean' fuel that will render Asia's burgeoning cities more livable. In Australia, it lies at the heart of a process of energy market liberalisation aimed at improved economic efficiency and expansion of Australia's energy-intensive export industries. This process, however, has yet to internalise the true value of gas in regard to environment and security. Moreover, whether the prosperity promised to the East Asia/Pacific region as a whole by new pipelines and LNG plants will be environmentally and logistically sustainable is a political question linked to events outside the region. As gas infrastructure becomes more regional in concept, and energy markets converge and become more competitive, there is a risk that the security and environmental problems associated with the 'age of oil', far from being ameliorated, will be perpetuated.

In the 1980s, Asian energy markets expanded at a rapid rate to meet the surge in demand from Japan, Korea, and Taiwan. This demand boom coincided with an increase in non-OPEC oil production in the region. As oil production stabilizes, demand looks set to rise sharply, this time in the new Newly Industrialized Countries of Southeast Asia, Thailand, Malaysia, and Indonesia. Natural gas will play a key role in this expansion of energy use and could start to lead rather than follow oil markets. The leading role of natural gas will be especially strong if gas starts to make inroads in the high and middle ends of the barrel with oxygenated gasoline and compressed natural gas for trucks. At the bottom of the barrel, natural gas could increasingly usurp the role of residual fuel oil for environmental reasons. At the same time, regional refiners could find that residual oil is their leading source of additional feed for the new process units currently under discussion or planning. The supply outlook for natural gas is increasingly fraught with uncertainties as more of the region's supplies must come from distant areas. In particular, LNG supplies from Malaysia and Indonesia will need to be replaced by the early part of the next century as rising domestic demand eats into the exportable gas production. New sources include China, Siberia, Sakhalin Island, Papua New Guinea, and Canada. There will be intense competition to supply the Northeast Asian markets as the gas production in Southeast Asia is increasingly used within ASEAN.
