A defining characteristic of Queensland’s natural gas industry is that upstream operations are located in a region with a strong and diverse agricultural industry. The gas resource lies beneath this farming land and the industry has had to overcome the challenge of covering huge distances to maintain thousands of gas wells and associated infrastructure – all while trying to reduce disruption on thousands of predominantly family-owned properties. Earning the trust and respect of landholders has, therefore, been essential to the success of the industry. Mistakes were made by the industry in the early days, but attitudes on both sides have since changed and evolved. There has been a move towards coexistence, respect and consent as the foundation for a long-term and mutually beneficial relationship. Along the way, the industry approach to land access has changed significantly over time. There are now many shining examples of best practice and innovation in the industry and a willingness to share solutions. This paper details the legal underpinning of Queensland’s land access process, the history of the industry in Queensland’s Darling Downs region, key lessons learned by the industry, and some of the innovations and new approaches developed by the land access professionals in the industry.

Current Production

Abstract Trinidad and Tobago offshore platforms have been producing oil and natural gas for over a century. Current production of over 1500 Bcf of natural gas per year (Administration, 2013) is due to extensive reserves in oil and gas. More than eighteen of these wells are high-producing wells, producing in excess of 150 MMcf per day. Due to their large production rates, these wells utilize unconventionally large tubulars 5- and 7-in. Furthermore, as is inherent with producing gas, there are many challenges with the production. One major challenge occurs when wells become liquid loaded. As gas wells age, they produce more liquids, namely brine and condensate. Depending on flow conditions, the produced liquids can accumulate and induce a hydrostatic head pressure that is too high to be overcome by the flowing gas rates. Applying surfactants that generate foam can facilitate the unloading of these wells and restore gas production. Although the foaming process is very cost effective, its application to high-producing gas wells in Trinidad has always been problematic for the following reasons: Some of these producers are horizontal wells, or wells with large deviation angles.They were completed without pre-installed capillary strings.They are completed with large tubing diameters (5.75 in., 7 in.). Recognizing that the above three factors posed challenges to successful foam applications, major emphasis and research was directed toward this endeavor to realize the buried revenue, i.e., the recovery of the well's potential to produce natural gas. This research can also lead to the application of learnings from the first success to develop treatment for additional wells, which translates to a revenue boost to the client and the Trinidad economy. Successful treatments can also be used as correlations to establish an industry best practice for the treatment of similarly completed wells. This paper will highlight the successes realized from the treatment of three wells. It will also highlight the anomalies encountered during the treatment process, as well as the lessons learned from this treatment.

It has been recognized that repair welding plays an important role in the long term, safe operation of pressure equipment. In 2009, The Japan Welding Society (JWES) published guidelines for repair welding of pressure equipment [1], to meet the great need for the safe operation and proper maintenance of aging plants. Pressure equipments made from carbon steel, high tensile steel and Cr-Mo steels are utilized for high pressure services. The subject equipments are pressure vessels, heat exchangers, piping, and storage tanks for petroleum, petrochemical and liquefied natural gas industry. This paper summarizes category and property of these steels and repair welding method including special attention. Especially, weld cold cracking for these steels could be prevented by controlling the repair welding and post-weld heat treatment process to reduce the hydrogen content, hardness and weld residual stress.

Abstract A scholarly consensus depicts strong, autonomous domestic women's movements as critical for the passage of gender equality reforms, alongside openings in domestic and international political contexts. What, then, is a nascent women's movement seeking gender equality reforms to do if it lacks strength or a history of autonomous organizing? A long-term analysis of the Guatemalan women's movement's push for reforms to address violence against women demonstrates that one potential road forward is through a “politics of patience,” rooted in the pursuit of cumulative, incremental victories. Adopting a politics of patience allows nascent domestic movements in developing and post-transition contexts to achieve incremental victories that create future political openings while simultaneously building movement strength and autonomy over time. This finding highlights the temporal and strategic power of women's movements, as well as the iterative and potentially reinforcing nature of social mobilization and political reform.

Volcanic Reservoirs

With the fast development of the natural gas industry, volcanic gas reservoirs have been paid an increasing attention. Many deep gas wells in volcanic reservoirs have special characteristics, such as high temperature, high pressure and high level of CO2 with strong corrosion effect, which brings great challenge to the safety of the tubing. Therefore, the mechanical analysis of tubing in deep gas wells in volcanic reservoirs is helpful to design the strings, optimize operation parameters and predict service life. In this paper, based on the buckling analysis, a mechanical model of tubing is established and solved by stepwise iterative algorithm. Physical properties of tubular strings and fluid are taken into consideration in new model, as well as the pitting corrosion of CO2. A program also developed for practical purposes. The results can be applied for the safety assessment and life prediction of the tubing in deep gas wells in volcanic reservoirs.

Regulatory Approach

The growth in domestic and global demand for energy has encouraged the development of new and innovative sources of energy. In Australia, the coal seam gas (CSG) industry has been in the vanguard of these advances with significant investment already in place to develop major CSG projects in Queensland. This rapid rise has highlighted the potential for other unconventional resources with proponents now exploring for new resources, such as shale gas, across Australia. Governments have generally attempted to support the development of these new industries. Regulatory reform has addressed the bespoke regulatory issues presented by unconventional gas production particularly in respect of water, land access and co-existence with other industries. Despite this the onshore gas industry continues to face political uncertainty, community division and divergent regulatory responses. Industry has consistently called for regulatory reforms to address duplication, remove unnecessary costs and improve approval processes to speed project delivery and enhance project returns while maintaining robust environmental protection obligations. State and Federal governments have responded to these calls for action in varying ways. While there is much to approve of in each of these processes each presents specific issues and risks that must be considered before they are implemented or more broadly adopted. Therefore, the question arises: What is the best long-term regulatory approach for the sustainable development of Australia’s unconventional resources? This paper reviews existing Australian regulatory approaches and analyses how regulators, industry and the community can work together to develop and implement a regulatory framework that achieves their respective objectives.

Ongoing Concern

An ongoing concern of service-learning projects is whether they can benefit target populations in the long-term. Too often, service-learning projects end before a real deliverable is presented to the community. At MIT, a short history of service-learning projects can be documented through the IDEAS Competition, an annual competition that awards small monetary prizes to student teams that have designed and implemented innovative projects to positively impact underserved communities. This article analyzes how winning projects of the first five IDEAS Competitions evolved or dissolved. From the experiences and wisdom of these early winners, this article offers six pieces of advice to students and academic institutions seeking to implement service-learning projects: 1) Seriously consider implementation from the beginning, 2) Be concrete and realistic in the short term, 3) Be flexible in the long-term, 4) Build a multidisciplinary team, 5) Collaborate with a solid community partner, and 6) Prepare for continuity.

ABSTRACT ObjectivesSHELS (Scottish Health and Ethnicity Linkage Study) linked Scotland's 2001 census to various hospital and death data sets with national coverage. Census ethnicity data were assigned to the study records to build a cohort of most of the Scottish population; included in the cohort were people with no health records. ApproachCreate a lookup table of a person's census index to the Scottish eHealth index, the CHI, equivalent of English new national health number. A modified versionof the eHealth administrative matching system was used to satisfy census confidentiality requirements. There were two linkages performed in 2004 and 2008. 2004 was a feasibility run; the 2008 applied lessons learned from the previous linkage and used much more completely indexed health records. ResultsThe first linkage produced match rate of 95% of 4.9 million 2001 census entries; the second 96%. Conclusions Lessons learned. Linking datasets using indexes is the most accurate and efficient way to produce study cohorts. Indices change over time; a methodology called 'reconciliation' was devised to retrospectively and continually adjust previously indexed (linked) records. How to Track members who migrate out of the cohort. A linkage resource called a residential events dataset (RESEVENT) was built for the 2008 linkage run; it holds merged history of linkage identifier fields by date from january 2000 to the present based on GP registrations. This introduces a time dimension to indexed linking.How to build RESEVENT like linkage resources; should they be census based? What should they contain? How to do daily national census and select controls for case/control cohorts from RESEVENT resource. How postcode changes over time can be handled (reconciled) - same address, different postcode, but no address present. Proposal for an index of national indices based on national administrative datasets starting with NHS number (new and old NHSCR) and NI number to make linking even more efficient - this is not a RESEVENT resource; this resource would mean data need be matched to index only once, all subsequent linkages would be deterministic links of reconciled indices.

Social Licence To Operate

The rise of activism is impacting the future of the Australian resources and energy industry. New projects suffer delays on a myriad of regulatory fronts, and fall victim to coordinated activist campaigns seeking to undermine their social licence to operate. Public trust in the natural gas industry is declining more rapidly in Australia than any other country, followed closely by the United States. In Australia, the industry is looking internationally for best practice approaches to turning this issue of perceptions around. In this paper I have drawn on the latest research and practical case studies from the United States to argue that harnessing the power of the workforce is the key to a strong, constructive response to activism and shifting community perceptions of the industry. I articulate the concept of constructivism in support of the resources and energy industries as an answer to activism, outlining strategies for successful constructivist campaigns, ultimately led by highly engaged Australian workforces. The method involves applying this constructivist approach to ‘Industry Employee Engagement’, creating a clear sense of purpose and emotional bond between your employees, their work and the industry. This sees employees motivated to take action and, when equipped with the appropriate knowledge and skills, discuss and promote the industry within their own community networks. Success will provide an aligned and unified approach to turning around perceptions of the industry and ensuring all Australians are fully informed and behind the role the industry will play in our nation’s future.

Introduction The long-term risk of first thrombosis and benefit of prophylaxis in antiphospholipid antibody (aPL) carriers without history of thrombosis or obstetrical morbidity is poorly known. This study aimed to evaluate the long-term rate and risk factors associated with a first thrombosis in those patients. Patients and methods After a prior study ended in December 2005 and was already published, we extended the follow-up period of our cohort of aPL carriers. Results Ninety-eight of the 103 patients of the previous study were included. The annual first thrombosis rate was 2.3% per patient-year during a median of 13 years (6–17). None of the baseline characteristics was predictive of risk of first thrombosis, but persistent aPL over time were associated with an increased risk. The stronger association was found in triple aPL-positive carriers: OR 3.38 (95% CI: 1.24–9.22). Of note, conversely to our previous findings, no benefit of aspirin prophylaxis was observed. Conclusion The risk of first thrombosis in aPL carriers without history of thrombosis or obstetrical morbidity was significant, persisted linearly over time and was associated with persistent aPL. This risk was especially increased in triple aPL-positive carriers, in whom a close follow-up seems to be necessary. Nevertheless, the benefit of aspirin prophylaxis remained unclear.
