The Polish Geological Institute – NRI has conducted investigations of the Kupferschiefer series since 1957, when the giant sediment-hosted stratiform Cu-Ag ore deposit was discovered in the central part of the Fore-Sudetic Monocline. Until 1991, a number of drilling programs were completed by PGI-NRI and later research has been focusing mainly on cooperation with oil and gas industry and their core material. Over the last few years, thanks to systematic examination of the drill holes located in the north-western extension, many prospective areas have been recognized and delineated. These prospects are located between Lubin-Sieroszowice deposit and the eastern part of the Zielona Góra oxidized field. In the Kożuchów area, the lower part of Zechstein copper-bearing series contain only relict sulphide mineralization accompanied by iron oxides while reduced rocks with metal sulphides occur in the uppermost part of Zechstein Limestone or at the base of Lower Anhydrite. Grochowice area, where reduced facies prevail in copper-bearing series, is characterized by the predomination of rich Cu-Ag mineralization proximaly to oxidized area. The western part of studied area is dominated by Cu-S type sulphides (chalcocite, digenite, covellite) whereas the eastern part is represented by Cu-Fe-S type minerals (bornite, chalcopyrite) with high galena and sphalerite concentrations. The spatial variability of sulphide mineralization with respect to the oxidized rocks indicates that Bytom Odrzański deposit extends in the north-west direction, continuing in the form of a copper belt along the eastern border of the oxidized area. An extensive deep exploration drilling program is implemented to verify the resource potential within predicted copper belt.

Analytical Tools

Oil and gas production is characterised by a truly international industry, and yet a unique local environment. Solutions developed elsewhere cannot always be imported directly for Australian use. For this reason alone, a strong local technology base is of value to the Australian oil and gas industry. Other benefits include the ability to provide high quality education and training for people entering, and already in, the industry.A case study is described where the Western Australian technology base is facilitating solutions to a specific challenge faced on the North West Shelf (NWS); namely, that the criteria for reliable development and operation of its offshore infrastructure for oil and gas production are more severe than other petroleum provinces, requiring new analytical tools to be developed.

Long Term Impact

The traditional planning for decommissioning oil and gas projects has included the option to remove platforms from the project area leaving the site clear for other uses. However, decommissioning presents a number of opportunities for alternative uses for facilities that are relatively close to the coast and in developing areas.This paper examines the potential for the alternative use of facilities on the North West Shelf using the WMC operated Airlie Project as an example.Airlie Island presents an opportunity to conduct a number of research activities which would have the capability to enhance the understanding of the natural environment in the region and to gain better understanding of the long-term impact of the oil and gas industries impact on the natural environment. There is also the supplementary opportunity to conduct engineering research applicable to the oil and gas industry without the distraction and hazards of an operating field to interfere with the research projects. Allied to these possibilities is the potential to conduct research applicable to tourism and fishing related activities which are beginning to exert more pressure and the North West Shelf environment than has been the case in the recent past.In addition to the research opportunities, there exists the potential to manage Airlie Island as a support base for tourism activities on a commercial basis. The example presented could easily be applied to other projects nearing decommissioning.

Focusing on Australian projects, this paper provides a summary of the key environmental challenges and developments that arose in 2010 and the industry’s response. The paper considers: developments in legislation and the regulatory environment relating to environmental approvals and management; major project approvals and their environmental requirements and implications; key environmental incidents; and reviews new environmental research and management initiatives that were introduced by the industry. A number of states have introduced changes to the way legislation and regulations are interpreted through changes to guidelines and administrative procedures. There has been a general increase in the standard and level of information that regulators expect proponents to provide and while generally these expectations are documented in guidelines and other documents, in some instances there has been a perceived ‘moving of the goal posts’ without clear guidance on what is expected and how the information will be considered once provided. There has been a number of major projects either commencing or gaining environmental approval in 2010. This includes major projects: in Western Australia, on the North West Shelf and in the Timor Sea/Browse Basin; onshore in Queensland in the coal-seam gas fields and continued exploration and development both onshore and offshore around Australia. One of the most significant approvals in 2010 was the Prelude LNG Project–the first approval in Australia of floating LNG technology. Major environmental incidents in 2009 (Montara in Australia and Macondo in the USA) continued to have repercussions in 2010 with the draft government response to the Report of the Montara Commission of Inquiry released in November. These incidents have put the oil and gas industry under the spotlight and this paper looks at some of the statistics on the frequency and severity of environmental incidents, albeit at a high level. Finally, the industry has continued to implement a number of environmentally related initiatives both in response to government policy and suggestion and independently through groups such as the APPEA environment committee.

In the last 12 months or so, particularly with the drop in oil price, there’s been a lot of speculation about the future of the Australian oil and gas industry. Strenuous efforts are being made to bring down costs, reduce complexity and expedite the completion of major capital projects. Yet with the commodity price looking likely to be subdued for some time, serious questions persist. How can we sustain activity in Australia, secure the investment needed to continue exploration and appraisal drilling, for the next wave of projects? In looking for answers to these challenges, collaboration is a theme that comes up time and time again. But what does it actually mean? What does it look like in practice? Who does it well and how? And which companies are reaping the rewards of great collaboration? To fill this knowledge gap we are launching a survey which will look at many aspects of collaboration in the Australia and compare this with the results of similar surveys conducted in the UK. We will be looking to survey both operators and service companies working in the Australia and find out: What does collaboration mean? What constitutes effective collaboration? How do companies view themselves and each other as collaborators? How does collaboration in Australia compare with companies in the North Sea? We hope a better understanding of collaboration could help companies in Australia continue to improve productivity and efficiency, adopt new ways of working, and truly make the most of Australia’s abundant resources.

The Cost

Tough market conditions have seen the price of oil drop which with the subsequent uncertainty surrounding the industry have seen the oil and gas industry concentrate on reducing the cost of designing, installing and operating pipelines. A critical process for the industry is the procurement, manufacture and installation of appropriate linepipe. The method of installation is often dictated by the pipe size and the water depth that the pipe is to be laid in, however there are times when the choice of lay method is due to vessel availability and relative costs for each technique. In early 2014, Tata Steel successfully manufactured and delivered 16"OD × 0.875”WT X65 submerged arc welded longitudinal (SAWL) linepipe for installation via the reel lay method. Notable features about this fact were the size, which represents the thickest 16” external diameter UOE pipe yet delivered by Tata Steel, and that this was to be the first UOE pipe to be installed by the reel lay method in the North Sea. The ability to manufacture small diameter thickwall linepipe was only possible due to recent operational developments including an established tooling programme and a fully validated Finite Element (FE) model of the UOE process, along with years of experience of integrating these tools into the manufacturing process. This paper discusses the manufacturing challenges for small diameter thickwall linepipe, and how with the aid of modelling tools, innovative thinking and previous experience in supplying small diameter thickwall linepipe into two reel-installed projects, the pipe was manufactured and delivered with the properties shown to be compliant with DNV OS-F101 Supplementary Requirement P.

The influence of industrial low-frequency electromagnetic fields on the human body is currently insufficiently studied. However, such fields are quite common in modern automated production, where various electric drives are used, and they significantly affect the quality of human life. This is especially evident in the conditions of the North, where special ecological factors cause significant changes in the systems of regulation of the body's functions. This study examines the influence of such fields on the parameters of the cardiovascular system of female workers in the oil and gas industry in Russia. Four groups of women were studied, differing in age and electromagnetic field exposure. As a result, the effects of influence of the fields were revealed, especially for the older age group.

Northwest Australia

An uncertain global economy, offset by strong commodity prices, provided the backdrop to a subdued yet solid level of exploration activity in 2010. The major loci of activity in the Australian oil and gas industry were the Exmouth Plateau, where exploration for conventional gas in support of LNG projects was the primary driver, and the Bowen/Surat Basin, where coal seam gas (CSG) for LNG was the main target. Onshore permit awards dominated new licensing in 2010, with 31 exploration permits awarded over an area of 190,000 km2. The majority of these permits are focused on unconventional gas exploration. Conversely only 14 exploration permits (30,000 km) were awarded offshore, all in northwest Australia. This historically low level can be related to an already extensive coverage of existing permits in the offshore petroleum provinces and delays in the announcement of acreage awards from the 2009(II) acreage release. Twenty-nine 2D seismic surveys were started in 2010, with three still active at the end of the year. Once completed, the 2010 surveys will total nearly 37,000 km of data, with 76% offshore. Twenty-one 3D seismic surveys commenced in 2010, with six still active at year end. The 2010 surveys will ultimately comprise approximately 29,000 km2 of data, with 95% offshore. Northwest Australia dominated seismic activities. Exploration drilling for conventional hydrocarbon resources was relatively subdued in 2010, with 63 wells spudded, compared to 92 wells in 2008 and 74 in 2009. Of the 49 wildcat wells where results are known, 51% reported hydrocarbon discoveries. This was a little less than the 57% in 2009 and up on the 39% in 2008. The discoveries were distributed across most of the traditional petroleum provinces. High levels of CSG drilling continued in 2010, exceeding 2008 activity but less than that of 2009. At least 648 CSG wells were spudded in 2010, mostly in the new heartland plays of the Bowen/Surat, Gunnedah and Clarence-Moreton basins. This compares with more than 600 CSG wells drilled in 2008 and more than 900 in 2009. The first dedicated Australian shale gas exploration drilling took place in 2010. Emerging shale plays in the Cooper and Perth basins were tested.
