Carbon dioxide (CO2) corrosion is one of the most dangerous types of destruction of metal products in the oil and gas industry. The field steel pipelines and tubing run the highest risk. Laboratory tests are carried out to assess the resistance of steels to carbon dioxide corrosion. However, unified requirements for certain test parameters are currently absent in the regulatory documentation. We present the results of studying the effect of the parameters of laboratory tests on the assessment of the resistance of steels to CO2 corrosion. It is shown that change in the parameters of CO2 concentration, chemical composition of the water/brine system, the buffer properties and pH, the roughness of the sample surface, etc., even in the framework of the same laboratory technique, can lead in different test results. The main contribution to the repeatability and reproducibility of test results is made by the concentration of CO2, pH of the water/brine system, and surface roughness of the samples. The results obtained can be used in developing recommendations for the choice of test parameters to ensure a satisfactory convergence of the results gained in different laboratories, as well as in elaborating of a unified method for assessing the resistance of steels to carbon dioxide corrosion.

Liquefied natural gas projects with a total value of around $20 billion are planned for Australia. Over the next decade or so, they have the potential to generate an increase of approximately 3% in Australia's GDP, and an excess of 50,000 jobs. One of the major risks to this vast investment is uncertainty over how to deal with the major increase in direct carbon dioxide (C02) emissions that will result from these developments. The 1997 Kyoto Protocol has served to focus even more attention on this issue.Potentially, a solution to sustaining Australia's economic development, whilst at the same time meeting emission targets, may lie, in part, in developing suitable methodologies for C02 sequestration. One of the key sequestration options is geological disposal. The method, which involves injection of supercritical C02 into the deep subsurface, is being tested on a commercial scale in only one place in the world at the present time, although several other countries are now developing research programs into the technique.The APCRC research program GEODISC is investigating the applicability of this method in Australia. Whilst the focus of GEODISC is on the application of C02 disposal to the Australian natural gas industry, its outcomes will have implications for other industries such as power generation and minerals processing. It will also be looking at some of the other potential benefits of geological sequestration, such as enhanced oil recovery and enhanced coalbed methane recovery.The program will establish the most viable locations for C02 injection, determine the key areas of technical, social and economic risk, and help define a pilot injection program to address the most critical areas of uncertainty. GEODISC brings together six major petroleum companies, the Australian Greenhouse Office and key Australian research groups. The total cost of GEODISC will be approximately $10 million over four years. The major expected outcome of GEODISC will be to help the Australian gas industry plan the way ahead in terms of C02 emissions in an environmentally acceptable manner, whilst concurrently ensuring that the industry does not incur major cost disadvantages, which may adversely impact upon Australia's international competitiveness.

The current state of the oil and gas industry of Ukraine and the possibility of increasing the hydrocarbon base due to the introduction of fields with compacted reservoirs, which contain significant gas resources. Some methods of intensification of wells that are used in Ukraine, such as hydraulic fracturing and the GasGun method, are considered. Their main shortcomings are given: unforeseen situations of depressurization of the water horizon, use of large volumes of water, utilization of process water, incomplete release of rupture fluid from the reservoir, swelling and hydration of clay components of the reservoir, impossibility of use at extremely high temperatures and pressures. The world modern technologies based on the action of inert gases in hydrocarbon production are covered. Studies on the application of anhydrous rock breaks and intensification methods using inert gases are analyzed. The application of the method of pneumatic compaction of coal seams in Ukraine with the use of flue gases for the release of methane and degassing of coal mines is presented. Modern studies on the use of liquid nitrogen and liquefied carbon dioxide as fracturing agents with rocks with low filtration–capacity properties are presented. The main advantages of using nitrogen, liquefied and supercritical carbon dioxide as reservoir decompression agents are presented. It is proposed to study the method of pneumatic compaction on different samples of rocks in the laboratory using various agents and surfactants, select the appropriate reagents and develop technology for pneumatic rupture of hydrocarbon reservoirs as a cheap and environmentally friendly alternative to existing methods.

Using the gravimetric method, the inhibitory efficiency of the combined inhibitor with respect to hydrogen sulfide and carbon dioxide corrosion of St3 steel in model produced water MI was studied. Corrosion tests were carried out in 0,5 liter sealed vessels on St3 samples of size 30х20х1. Gossypol resin + MARZA was used as a multifunctional combined inhibitor. Diesel fuel and kerosene were used as solvent. It has been established that the protective effect of using a multi-functional combined inhibitor in formation water with oil containing hydrogen sulfide and carbon dioxide using kerosene as a solvent ranges from 75 to 96 and for diesel as 80 to 100. The combined inhibitor allows to achieve in the MI medium containing hydrogen sulfide and carbon dioxide in the process of daily testing the corrosion rate of steel is about 0,04 g/m2·h. only in a concentration of not less than 70 mg/l. However, with an increase in the duration of the test by an order of magnitude, a similar corrosion rate is observed already at an inhibitor concentration of 50 mg/l. The same is characteristic of carbon dioxide and hydrogen sulfide - carbon dioxide solutions.

The shale gas debate has taken center stage over the past decade in many European countries due to its purported climate advantages over coal and the implications for domestic energy security. Nevertheless, shale gas production generates greenhouse gas and air pollutant emissions including carbon dioxide, methane, carbon monoxide, nitrogen oxides, particulate matter and volatile organic compounds. In this study we develop three shale gas drilling projections in Germany and the United Kingdom based on estimated reservoir productivities and local capacity. For each projection, we define a set of emission scenarios in which gas losses are assigned to each stage of upstream gas production to quantify total emissions. The “realistic” (REm) and “optimistic” (OEm) scenarios investigated in this study describe, respectively, the potential emission range generated by business-as-usual activities, and the lowest emissions technically possible according to our settings. The latter scenario is based on the application of specific technologies and full compliance with a stringent regulatory framework described herein. Based on the median drilling projection, total annual methane emissions range between 150–294 Kt in REm and 28–42 Kt in OEm, while carbon dioxide emissions span from 5.55–7.21 Mt in REm to 3.11–3.96 Mt in OEm. Taking all drilling projections into consideration, methane leakage rates in REm range between 0.45 and 1.36% in Germany, and between 0.35 and 0.71% in the United Kingdom. The leakage rates are discussed in both the European (conventional gas) and international (shale gas) contexts. Further, the emission intensity of a potential European shale gas industry is estimated and compared to national inventories. Results from our science-based prospective scenarios can facilitate an informed discussion among the public and policy makers on the climate impact of a potential shale gas development in Europe, and on the appropriate role of natural gas in the worldwide energy transition.

Is the reservoir half full or half empty? Both scenarios are one for the optimist depending on whether that optimist is a petroleum producer, or a greenhouse gas storage provider. As Australia looks towards greenhouse gas storage as an important option for reducing carbon dioxide emissions, greenhouse gas storage may herald the emergence of an entirely new industry. This new industry will have far-reaching impacts across a broad spectrum of existing industries, not least of which is the upstream petroleum and gas industry. In this time of increasing demand for gas, not only will competition for the same geological spaces remain rife among petroleum and gas producers, but greenhouse gas storage providers may seek these very same spaces for their own operations. Other points of contention between the industries could include concurrent land use on overlapping tenures and the development, operation and ownership of pipelines. Petroleum and gas industry participants will need to adapt to the new challenges arising from the emergence of greenhouse gas storage. And if petroleum and gas producers decide to take up some of the opportunities offered by the new industry, they will need to grapple with significant questions about feasibility and risk associated with greenhouse gas storage projects inherent in the legislative regimes enacted to date. Using Queensland’s new Greenhouse Gas Storage Act 2009 as a platform, Ben Cansdale will examine these challenges and discuss the potential impact a greenhouse gas storage industry will have for Australia’s petroleum and gas industries.
