Increasing Labor Efficiency Repairing Metal Structures of Heavy-Duty Quarry Machinery
Authors: Drygin Michael , Kuryshkin Nikolai
Published: June 2019

Supporting metal structures of large dump trucks at open cast coal mines function under exposure to alternating cyclic load. Fatigue cracks that appear there require timely maintenance welding. Organization of repair processes is multivariant; it can be performed either by the enterprise (open cast coal mine) efforts or by special repair units. An industrial experiment carried out at Permyakovskiy and Prokopyevskiy open cast coal mines in Kuzbass has shown that type of large dump trucks’ repair works organization influences significantly process efficiency. Repair welding by enterprise efforts is the most non-productive compared to other types of repair process organization. Its specific rate is 37 per cent lower than in comparison with unstructured welding and 2.2 times lower in comparison with structured metal sheet replacement and structured welding. Structuring repair processes allows to increase their efficiency by 30...40 per cent on average. Structured replacement of the spring plate is the most productive type of metal structure repair process organization. Comparison of maintenance measurement results in accordance with Unified Norms and Prices collected book with the results obtained from the industrial experiment showed that calculation methods give underestimated values of repair processes’ specific rate.

Authors: Dubov Georgiy , Trukhmanov Dmitriy , Kuznetsov Iliya , Nokhrin Sergey , Sergel Aleksey
Published: June 2019

The state-of-the-art of the advantages of using liquefied natural gas as a motor fuel for haul trucks instead of oil motor fuel is considered. It is noted that the energy intensity of the process of rock mass hauling by dual-fuel (gas-diesel) haul trucks is less than that of haul trucks running on diesel only. It is argued that the most promising in relation to heavy-duty mining trucks, is the conversion of diesel engines to gas-diesel operation. The universal integrated procedure for evaluating currently used haul truck on-board cryogenic fuel systems performance is presented. The method of evaluating the “rate of replacement” of diesel fuel with liquefied natural gas, when operating haul trucks equipped with on-board cryogenic fuel systems, is described in detail. The possible sequence of per-cycle, per-ingle-shift and per-day monitoring of the rate of diesel fuel replacement with liquefied natural gas is presented. The method for evaluating the economic efficiency of the operation of high-payload-capacity haul trucks conversed to gas-diesel operation is given, which allows, among other things, determining the actual service life of on-board cryogenic fuel systems and their time to failure.

Authors: Kashirskikh Veniamin , Zavyalov Valery , Semykina Irina , Borovtsov Valery
Published: June 2019

The possibility of carrying out monitoring of parameters and variables of the induction electric motor (IM) working as a part of the electric mining machinery drive is considered. Monitoring is carried out on the working inventory in real time by means of the computer system on the basis of the IM mathematical model, mathematical estimation methods and also information which is contained in easily measured phase tension and IM stator currents. As a result IM indicators are defined difficult or cannot be measured in the mining machinery operation course. These are the active and induced windings resistances of a stator and a rotor, a magnetic linkage, an angular frequency of a rotor rotation and the electromagnetic moment. Algorithms of dynamic IM identification and the software are developed for carrying out monitoring. Theoretical provisions and conclusions are confirmed with results of the pilot studies. Information received during monitoring can be used for perfecting of the electric drive.

Authors: Barbara Anna , Sluder Lyubov
Published: June 2019

The fossil fuel sectors and export of its products occupy a leading position in the economy of many countries and directly affect the sustainability of national economies. Therefore, in the long term an adequate vision of the development of these sectors is of great importance in forecasting and planning the strategic development of these countries. The wide use of coal fuel in the world energy consumption will remain for quite a long time; however, the environmental problems associated with its production are a serious factor hindering the possibility of a transition to the sustainable development of coal-producing regions. There is an obvious need for a balanced approach in developing greater industrial potential while protecting the environment. The world is slowly moving away from coal as other forms of energy have become cheaper and environmental concerns mount. The authors analyzed the world and domestic experience in the initiation, promotion and implementation of projects that contribute to the sustainable development of the leading mining regions of the world. The ability of the authorities to clearly define strategic priorities, improve the business climate, effectively distribute and improve the quality of regional resources and infrastructure creates the prerequisites for enhancing the sustainable competitive advantages of a region, business, and public welfare.

Start-ups as an Element Supporting the Development of the Mining and Energy Sector
Authors: Pukala Ryszard
Published: June 2019

This study aims at presenting opportunities offered to the mining and energy industry by the emergence and operation of high-risk enterprises – start-ups. Moreover, it analyses interrelations between the developmental status of such entities and their lifespan. We need to stress that start-ups are mostly associated with modern technologies that are used and implemented in various sectors of the economy. Therefore, they are classified as innovative and innovation-implementing enterprises, which gives them a chance to gain market success and competitive advantage. As shown by conducted analyses, start-ups can be an efficient element that supports the development of mining and energy enterprises. At the same time, again on the basis of analyses, start-ups, quickly developing and maturing as well as seeking their own business model, exhibit the largest risk of losing financial liquidity.

It reveals that economic instability can affect the investment climate, as well as cause significant slowdown of the innovation process. It points out the differences in adaptation processes in regions, which are reflected in the pace and direction of innovation implementation. An assessment of the innovation potential of a resource-type region was carried out based on indicative method and a set of criteria which were divided into five groups. The groups are formed according to scientific, technical, personnel, financial and resulting components. The analysis revealed that the resulting component is in a pre-crisis state, which is determined by the small number of active enterprises introducing innovation technologies and a small share of innovative products. It was noted that the technical and personnel components are in a normal state, and the financial component is in the state of crisis. It was concluded that there exists a sufficiently high innovation potential in the basic sectors of the industrial region. The debatable results of any assessments of the innovation potential and its impact on the sustainability of socio-economic development are underlined.

The Kemerovo Region is the leading coal cluster of Russia and Europe, where about 60% of all domestic coal is mined, 42 mines and 51 open-pit mines are operating, as well as 54 coal processing plants and installations. At the beginning of 2019, more than 90 thousand people worked in the coal industry of Kuzbass. The task of increasing the labor productivity of coal enterprises is largely determined by personnel potential, which is the main productive force in the post-industrial era. Enterprise staff is the creator of all the material and intellectual values of the coal industry, without exception. Today, the maximum use of all available internal production resources depends on the quality of university training of miners, the formation of their professional and communicative competences. This study focuses on the use of new technologies in learning foreign language by future mining engineers. It discusses a variety of attitudes and incentives which support the readiness of students in this field to increase their learning skills through using ICT. In this paper, the authors review practices and experience of using the technology in classroom summarized in expert opinions of foreign language teachers working with undergraduate students – future mining engineers.

Authors: Pinchuk Alina , Tkalenko Nataliia , Marhasova Vyktoriia
Published: June 2019

The article is devoted to the issue of waste management in the mining regions, as the problems of industrial waste or waste products will always be relevant in nowadays. The most experts focus on urbanization processes, on increasing the resources’ requirements, which in turn will increase the needs of the population and environmental pollution. The processing of waste in the mining regions can be achieved through the use of elements of the circular economy, which will lead to the economic use of natural resources and the interaction of economic, environmental and social development. The building of Eco-Industrial Park using a sector-clustered approach to waste management is suggested in the conclusions. The Eco-Industrial Park will allow related industries to work in symbiosis, where secondary raw materials can be involved in recycling, remanufacturing, recovery, regeneration.

Published: June 2019

The objective: to consider the peculiarities of social tension occurrence in the coal-mining region. Methods: the research is based on the awareness of the fact that social tension is a mass adaptation syndrome that reflects the degree of different population categories physiological, psychophysiological and social-psychological adaptation (or maladaptation) to chronic frustration, hardships (drop in living standards and social changes).Social tension is addressed through the lens of both population categories: the population living on the territory of a coal-mining region but not employed in coal-mining industry as well as population directly employed in coal-mining industry. Results: the factors influencing the degree of social tension of the population living in a coal-mining region and directly employed in coal-mining industry have been released. Conclusion: the ways of social tension in coal-mining region easingbased on integrated research data have been offered. It has been determined that sustainable development of a coal-mining region must be connected with the following interrelated aspects: ecosystem preservation, satisfaction of human needsas well as life quality satisfaction together with efficient resources distribution and others. It has been proved that maximum involvement of thecitizens in social and political life plays the discrete role in the process of social tension easing in a coal-mining region.
On the frequency-dependent effective viscosity of laminar and turbulent flows
Authors: Ogilvie G.I.
Published: June 2019

The efficiency of tidal dissipation in convective zones of stars and giant planets depends, in part, on the response of a three-dimensional fluid flow to the periodic deformation due to the equilibrium tide — a problem considered by Jean-Paul Zahn in his PhD thesis. We review recent results on this problem and present novel calculations based on some idealized models.
The formation of long-period eccentric binaries with a helium white dwarf companion
Authors: Siess L.
Published: June 2019

The recent discovery of long-period eccentric binaries hosting a He-white dwarf has been a challenge for binary-star modelling. Based on accurate determinations of the stellar and orbital parameters for IP Eri, a K0 + He-WD system, we propose an evolutionary path that is able to explain the observational properties of this system and, in particular, to account for its high eccentricity (0.25). Our scenario invokes an enhanced-wind mass loss on the first red giant branch in order to avoid mass transfer by Roche-lobe overflow, where tides systematically circularize the orbit.
Measuring the core rotation of red giant stars
Authors: Gehan C. , Mosser B. , Michel E.
Published: June 2019

Red giant stars present mixed modes, which behave as pressure modes in the convective envelope and as gravity modes in the radiative interior. This mixed character allows to probe the physical conditions in their core. With the advent of long-duration time series from space-borne missions such as CoRoT and Kepler, it becomes possible to study the red giant core rotation. As more than 15 000 red giant light curves have been recorded, it is crucial to develop a robust and efficient method to measure this rotation. Such measurements of thousands of mean core rotation would open the way to a deeper understanding of the physical mechanisms that are able to transport angular momentum from the core to the envelope in red giants. In this work, we detail the principle of the method we developed to obtain automatic measurements of the red giant mean core rotation. This method is based on the stretching of the oscillation spectra and on the use of the so-called Hough transform. We finally validate this method for stars on the red giant branch, where overlapping rotational splittings and mixed-mode spacings produce complicated frequency spectra.

Contributions of Fibroblasts, Extracellular Matrix, Stiffness, and Mechanosensing to Hepatocarcinogenesis
Authors: Filliol Aveline , Schwabe Robert F.
Published: June 2019

Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. A unique feature of liver cancer is its close association with liver fibrosis. About 90% of HCCs develop in advanced liver fibrosis or cirrhosis, suggesting an important role for the fibrotic microenvironment in driving HCC development. Here, the authors will discuss functional contributions of liver fibrosis to the development of HCC, focusing on mechanisms through which fibrosis may promote HCC development such as hepatic stellate cell-derived extracellular matrix, growth factors, and cytokines, stiffness-induced signaling pathways, and immunosuppression. Better understanding of these factors in HCC development and progression may provide the basis for novel stromal-based therapies for tumor prevention or therapy.
Conquering the Rock—A Retrospective Single-Center Experience of the Transapical Petrosal Transtentorial (Kawase) Approach: Operative Technique and Impact on Cranial Nerve Function
Authors: Volovici V. , Dammers R. , Dirven C. M. F. , Delwel E. J.
Published: June 2019

Since its description in 1985, the transapical petrosal transtentorial or Kawase approach has become a viable option of approaching lesions located in and around the apex of the petrous bone, Meckel's cave, and the anterolateral surface of the brain stem while preserving cranial nerve function. At the Brain Tumor Center, Erasmus MC, 25 patients were treated using the Kawase approach between 2004 and 2018 for various indications, including petroclival meningiomas, chondrosarcomas, pontine cavernomas, trigeminal schwannomas, and posterior circulation aneurysms. Hearing preservation was achieved in all patients; new abducens nerve and trochlear nerve palsies were present in three and six patients, respectively, of which a total of eight required ophthalmological correction. Seven patients experienced a cerebrospinal fluid fistula postoperatively, but this complication appeared self-limiting in all cases, with one patient experiencing secondary meningitis. After modifying our closure technique, the rate of fistulas dropped to zero. The observed direct postoperative mortality was 4% (one patient), although not related to the approach itself. In conclusion, the Kawase approach is a highly complex, but essential middle fossa approach, extremely robust, and able to serve a wide array of pathologies together with its extensions. It is very accurate for performing hearing preservation surgery, but not without caveats and inherent risk of complications.

Published: June 2019

Background Lesions affecting sphenoid sinus lateral recess (SSLR) are difficult to visualize and manipulate through the transnasal routes, especially when the sinus is highly pneumatized. External approaches to this area involve extensive surgery and are associated with significant morbidity. The aims of this study are to present our experience with the endoscopic transpterygoid approach as a method for approaching lesions of the SSLR and to evaluate the outcomes of this procedure.

Methods Clinical charts of patients who had lesions in the SSLR and who were treated at our institution from September 1998 to June 2018 were retrospectively reviewed. All these patients were managed by the endoscopic endonasal transpterygoid approach.

Results Thirty-nine patients were identified. No cerebrospinal fluid leak recurrences were observed during follow-up (range: 1–19.7 years; median: 2.3 years). Hypoesthesia (temporary, 1; persistent, 4) in the region innervated by the maxillary branch of the trigeminal nerve was detected in five (12.8%) patients, while symptoms due to the Vidian nerve damage (dry eye, 3; dry nasal mucosa, 1) were present in four (10%) patients.

Conclusions Although the endoscopic endonasal transpterygoid approach is an excellent corridor for dealing with lesions of the SSLR, limited rate of neurologic and lacrimal complications was observed. Potential morbidity of the intervention should be discussed during preoperative counselling.
The power of digital: workplace tools to modernise safety compliance
Authors: Ahlgren Karl V. , Shibi Naaman
Published: June 2019

Jobs and industries around the globe are following the Darwinist model of needing to adapt to change for survival. A high proportion of the next generation entering colleges, technical and further education (TAFE) and universities today are preparing for jobs and tasks that do not exist yet. Recent technological advancements have meant that some industries and workforces are at risk of being left behind. With national and international safety regulations getting increasingly strict and competition tightening, the importance of maintaining a modern workplace and workforce to comply with safety procedures has never been more apparent. The oil and gas industry is one such field where safety audit, compliance and effective inspection are paramount. With considerable industry regulations, standards and checks, it is imperative that there are good systems in place. Implementing mobile technology is fast becoming the universal solution within the oil and gas industry to ensuring effective management and thorough compliance.
Rigorous gas field production data analysis
Authors: Evans Christopher , Corrie-Keilig Antony
Published: June 2019

With the advent of permanent downhole gauges and automated flowing tubing head pressure measurements, today’s engineers have a veritable plethora of production data on which to characterise gas reservoirs and estimate their ultimate recovery. As consultants, the authors see datasets that have not always been examined to their fullest potential. More often than not this is due to a singular approach to analysis, rather than application of a range of analyses. This paper discusses how combining traditional and more advanced production data analysis techniques has provided insight into fields ranging from tight gas reservoirs to conventional reservoirs under active waterdrive. Such insight is not obtained from brute force application of one size fits all techniques but understanding and using the appropriate combination of techniques that are likely to illuminate the underlying physics of the reservoir at hand. The authors have seen examples where basic data analysis has identified resource ranges outside the range estimated from sensitivity studies with detailed and sophisticated but effectively singular models.
A new spatially continuous basement heat flow map for NW Queensland
Authors: Jorand C. , Connors K. , Pryer L. , Pietrucha C.
Published: June 2019

A recently released open file study of the depth-to-basement and basement heat flow is presented, which covers the Queensland portion of the South Nicholson Basin and includes basins underlying the Lawn Hill Platform and Georgina Basin. The present-day basement heat flow model is derived from an analysis of basement composition, structure and history, with the crustal radiogenic and mantle heat flow assessed separately. Resulting from an integrated, iterative interpretation and analysis of a wide range of publicly available spatially continuous geophysical and geological datasets, the heat flow model reproduces faithfully sharp and high-amplitude variations of the published heat flow at small distances. Variations are replicated through the integration of interpreted basement composition and a geologically driven determination of heat production within the radiogenic crustal layer. The values of mantle heat flow based on lithosphere thickness derived from seismic tomography models are consistent with published stable mantle heat flow under terranes of similar age. The long-wavelength regional variations can be attributed to the change in the thickness of the lithosphere. Regionally, the highest values of heat flow are found where radiogenic crust is the thickest and the composition is interpreted to comprise radiogenic intrusives.

Published: June 2019

In 2017, the Australian Institute of Marine Science and its partners commenced the North West Shoals to Shore Research Program. The program is designed to address significant scientific and environmental knowledge gaps pertinent to the management of the offshore petroleum industry, a key stakeholder in this ecologically and commercially important region of Australia. The program comprises four themes.
1. Marine noise monitoring and impacts: includes two seismic source (2600 cubic inch air-gun array) exposure experiments have been conducted to investigate selected responses by demersal fishes and pearl oysters across different spatial and temporal scales.
2. Seabed habitats and demersal biodiversity: seeks to understand the physical and biological characteristics of the ancient coastline key ecological feature around the 125 m depth contour and pearl oyster habitats offshore from Eighty Mile Beach. The work examines the ecological processes that maintain benthic communities on both ancient and contemporary coastlines
3. Protected and iconic species movement, distribution and threats: uses innovative sampling techniques to confirm biologically important areas for pygmy blue whales, hawksbill and green turtles. This will assist the quantification and mitigation of the risks vessel movements, industrial infrastructure and activities pose to marine megafauna on the Northwest Shelf.
4. Spatial dynamics of isolated coral reef atolls: develops a habitat model and adaptive monitoring program that informs the future condition of these remote coral reef atolls.
Significant progress has been made by the program in 2018, including the development of innovative and technical approaches to sampling.
Meeting demand in a new era of east coast gas supply
Authors: Pulsford Will
Published: June 2019

Historically LNG projects have been established to monetise large gas finds in remote areas with little existing gas demand. The development of gas supply to the LNG project generally stimulated demand growth in the domestic gas market. As the supplying fields depleted, the LNG projects faced competition with domestic producers for declining gas supplies, but this was late in the project life when LNG plant capital had already been recovered. Recently, LNG export projects have been established within existing mature gas markets, most notably in Australia and North America. These plants now face competition with domestic gas consumers for access to feed gas from the beginning of their operational life when strong revenue has the greatest impact on the return earned on capital invested, with the greatest stress felt in Australia. This paper considers the underlying causes of domestic price rises experienced in Australia following the start-up of LNG export supplied from gas fields linked to the domestic market and the response by both plant developers/operators and the government. This historical view is used to inform forecasts of how the east coast gas market will react to the interplay between domestic and LNG plant demand, declining Bass Strait production, maturing CSG operations, LNG imports and completion of the Northern Gas Pipeline. In particular the ability of gas supply and pipeline capacity to meet the strongly seasonal domestic demand in Victoria and to a lesser extent NSW will be examined, together with the linkage to counter-cyclical seasonal demand for LNG from the Queensland LNG export plants in the key north Asian markets.

The Roebuck Basin and the adjoining Beagle and Barcoo sub-basins are underexplored areas on Australia’s North West Shelf that are undergoing renewed exploration interest since the discovery of oil at Phoenix South 1 in 2014 and subsequent hydrocarbon discoveries in the Bedout Sub-basin. A well folio of 24 offshore wells across the Beagle, Bedout, Rowley and Barcoo sub-basins has been compiled as part of Geoscience Australia’s hydrocarbon prospectivity assessment across the region. It consists of composite well log plots and well correlations that summarise lithology, lithostratigraphy, Geoscience Australia’s newly acquired biostratigraphic and geochemical data as well as results of petrophysical analysis. A revised sequence-stratigraphic interpretation, key petroleum system elements and drilling results are also documented. The wells dominantly target Triassic shoreward facies (Keraudren Formation) as the primary reservoir objective and Jurassic fluvial-deltaic (Depuch Formation) and/or Lower Cretaceous sandy deltaic facies as the secondary objective. The Keraudren Formation sandstones are sealed intra-formationally either by discontinuous units and/or by the regional Cossigny Member. The Jurassic Depuch Formation sandstones are sealed by regional Lower Cretaceous mudstones. Both charge and structure have been identified as critical issues in the Roebuck Basin. In the Beagle Sub-basin, seal integrity and migration pathways are also considered high risk. Well correlations have identified differences in the basin history and provide insights into the distribution of facies and other characteristics of the Jurassic and Triassic successions.
Regional paleodepositional environment of the Cretaceous in the Great Australian Bight – a support for frontier exploration
Authors: Klauser-Baumgärtner Detlef , Reichel Thomas , Hansen John-Are
Published: June 2019

To reveal the development of the depositional environment in the Great Australian Bight, regional and high-resolution 3D-seismic interpretation and palynological evidence from well data was integrated with tectonic plate- and paleo topographical-reconstructions. Results from that work explain the drainage patterns and changes in the sedimentary evolution. A maximum transgression at the Cenomanian–Turonian boundary causes the deposition of the expected main source rock interval at the base of the Tiger mega-sequence. This is supported by Integrated Ocean Drilling Program wells (2017), asphalite strandings and dredge samples from the basin. A relative sea-level drop in the mid-Turonian initiates a forced regression and sand deposition in more distal parts of the basin. As a third mega-sequence the Hammerhead Formation progrades into the basin, depositing several thousand metres of deltaic sandstones and lagoonal shales. Our source to sink model based on our gross depositional environment maps could explain the presence of source rocks and reservoir intervals within this frontier exploration basin.
Reducing maintenance burden on established facilities through a targeted risk review of safety critical equipment
Authors: Innes Bronwyn
Published: June 2019

Traditionally, safety critical equipment is identified in the computerised maintenance management system, at a whole- or subsystem level, during detailed design. Once the computerised maintenance management system is commissioned, thousands of equipment tags are identified as safety critical, and the categorisation is rarely looked at holistically again. As an industry, we are constantly working to reduce the maintenance and operating costs of our facilities without compromising safety. A change in operating risk profile of a facility presents an often-overlooked opportunity to achieve this. A risk-based review of safety critical equipment identified in the computerised maintenance management system can allow for reduction of the critical maintenance burden and facility operating costs. For established facilities, a detailed review of safety critical elements and equipment is generally limited to life extension projects or major brownfields modifications. However, over the operating life of a facility the risk profile and risk tolerances may change. This paper considers three potential causes of change and the opportunities that arise. These causes of change include: (i) change in risk profile due to changing operating conditions, e.g. reservoir depletion; (ii) change of operator resulting in a different operational risk appetite; and (iii) changing in industry risk data or methodologies. Applying a targeted risk-based review to the high-value or high-risk safety critical equipment affected by these changes can provide justification of changes to their safety criticality rating. This paper presents a methodology for providing a transparent, risk-based approach to re-classifying safety criticality which aligns with regulatory requirements and stakeholder expectations.
Australia's shale industry – how we can become globally competitive
Authors: Cox Peter
Published: June 2019

Project delivery technology is changing and developing at a rapid rate, and Australia’s oil and gas industry could do a better job of embracing change and getting to the forefront of advanced digital technology applied to developing onshore gas resources – particularly to our vast undeveloped shale reserves. Our shale deposits are in remote parts of our country, so present significant challenges, especially in relation to geographical distance away from local and international markets. This paper will focus on the use of automation and standardisation in the engineering design process combined with project execution strategies to significantly reduce both schedule and cost in delivering surface infrastructure required to get our gas shale reserves to both domestic demand centres and export facilities. The traditional project delivery models that have served us well in the past need to be challenged and a new paradigm adopted. Standardisation of the compression and dehydration facilities in the US market has been developed over many years, resulting in efficient project delivery, and enabling reserves to be brought to market on a fast track basis. This paper will work through practices in the US and how they can be applied to Australia. Australian standards and industry practice defines how we design our gathering and pipeline networks. This paper will present a combination of construction strategies and automation of engineering design to optimise life cycle cost in remote regions where construction mobilisation and logistics is a significant factor combined with changing priorities as further reservoir data is obtained from exploration wells.
Reflections of a contemporary gas regulator in Queensland
Authors: Date William
Published: June 2019

Contemporary regulation needs a modern approach and the right attitude by inspectors. Gone are the days when an inspector can walk onto a petroleum lease and berate a site safety manager. Instead the regulator needs to be firm, fair and friendly. The Department of Natural Resources, Mines and Energy (DNRME) Petroleum and Gas Inspectorate (PGI) is delivering contemporary regulation using the following three key approaches: the five lines of operation, appreciative enquiry and engagement. The five fundamental elements of a contemporary effective risk-based safety regulator of the petroleum and gas industry in Queensland are as follows:
(1) Proactive engagement – build safety capability across industry and actively contribute to sharing harm-reduction practices and safety information
(2) Modern legislation – be less prescriptive on how to work
(3) Risk-based approach – focus regulatory effort to areas of greatest risk
(4) Look for success – recognise and share examples of safety improvements with positive workplace outcomes; do not just focus on non-compliance
(5) Professional expertise – demonstrate staff expertise and encourage ongoing professional development
Petroleum and gas (P&G) inspectors are learning about the appreciative enquiry technique through Griffith University. This learning is equipping inspectors with new techniques to undertake their core task of inspections and audits, focusing on what is working well and not just non-conformance. This approach ensures that industry and the regulator can both learn from, and improve, safety outcomes. In 2017, the Inspectorate created the P&G Stakeholder Engagement Committee (SEC). The SEC collaborates and communicates with senior leaders in the gas industry. The committee is used to bring focus on current compliance and regulatory priorities (as well as looking for safety improvements), yet it creates openness, trust and mutual respect between industry and the regulator.
Cumulative groundwater impact assessment and management in the Surat Basin: a journey from framework to implementation
Authors: Pandey Sanjeev
Published: June 2019

The coal seam gas (CSG) industry in Queensland has expanded rapidly in the Surat and Bowen basins within this decade. Depressurisation for CSG production has the potential to affect overlying and underlying aquifers. This leads to wide-ranging stakeholder concerns around the groundwater impacts, particularly cumulative effects, because the coal seams are part of the Great Artesian Basin. Relatively early in the development cycle, Queensland set a framework whereby an area of intensive petroleum and gas development is proactively declared to be a cumulative management area. For such areas, the independent Office of Groundwater Impact Assessment (OGIA) undertakes cumulative impact assessment and prepares management arrangements that are reported through the underground water impact report. OGIA’s assessment through its iterative reporting–monitoring–modelling cycle has been providing the basis for managing and monitoring groundwater impacts on the ground and providing clarity in tenure holders’ responsibilities. OGIA has also built extensive knowledge of the groundwater systems and developed innovative modelling techniques over the years that have wider application elsewhere. This paper shares OGIA’s journey in the process.
