The Chevron-operated Gorgon Project is located off the northwest coast of Western Australia and encompasses a number of mega-projects including an all-subsea upstream development of the Greater Gorgon gas fields, a greenfield gas processing facility including a 15MTPA liquefied natural gas (LNG) plant and a 300TJ/d domestic gas plant, and the world’s largest commercial scale carbon dioxide injection project. Due to its sheer size, scale and complexity, in addition to a number of unique characteristics, the Gorgon Project has required an extraordinary level of project execution planning. One aspect is the processing plant’s location on Barrow Island—a remote Class A nature reserve. Core to the project’s planning and success is a meticulous and robust environmental management system designed to protect Barrow Island’s unique flora and fauna. This includes stringent environmental measures such as limits on worker population and movement, quarantine requirements for all personnel, and materials and work adjustments for seasonal flora and fauna life cycles. The project’s scope of work is also being executed from three centres: LNG facilities centered in London, infrastructure centered in Perth and construction operations centered in London, Perth and Barrow Island (according to the phase and priorities of the project). This paper explores the following factors: the remote location of the gas fields; cohabiting industry with Barrow Island; minimising environmental impacts using efficient construction management methods such as modularisation; and working together as one team across multiple locations and time zones to demonstrate how the extraordinary can be achieved.

Environmental Measures

As interests in the impacts of business activities on environment have been growing, environmental policy is now shifting from the “end of pipe” stage to the next stage, which factor in the life cycles and social efficiency. An increasing trend in environmental departments of state and municipal governments in Europe is that these departments have outgrown their restriction-based environmental measures. Their concept of environmental policy has shifted to management support programs that helps small- and medium-sized enterprises (SMEs) increase their competitiveness through improving their environmental efficiency. This chapter discusses and compares two environmental programs: the case of die Effizienz Agentur NRW (EFA) and the case of der ÖkoBusinessPlan Wien, the Eco Business Plan Vienna (EBP). The goal of this chapter is to extract the conveyed meanings of partnerships and the role of public sectors through the activities of local intermediaries such as agents need to play in fostering environmental conservation. The focus of discussion is on the partnerships among the parties involved in the programs and on the program operations.

The Impact

The Hides gasfield was discovered by BP, and its Joint Venture Partner Oil Search Ltd, in Petroleum Prospecting Licence No.27 in Southern Highlands Province in late 1987 by the exploration well Hides-1. The well tested gas at rates of up to 15.9 mmscf/d with small volumes of associated condensate from four separate intervals within the Toro Sandstone.Negotiations with Placer Dome, a Vancouver-based mining company, led to an agreement to sell gas to supply electrical power for the Porgera gold mine in Enga Province 70 km North East from Hides. Approximately 10 mmscf/d of gas will be produced from two wells, one being the original Hides-1 discovery well, via an 8 km pipeline, to a gas processing plant in the nearby Tagari valley. The processed gas will be fed to turbines to generate approximately 42 M W of electrical power which will be fed to the Porgera mine by overhead transmission lines.BP has undertaken technical studies relating to the feasibility of producing the gas from Hides. In association with the technical work BP has also undertaken an environmental study of the impact of development and has embarked upon a survey of various local and land-related issues. It is anticipated that construction operations will start in early 1990, leading to first gas production in mid-1991, only 3½ years after the discovery. The Hides gasfield development will constitute the first commercial hydrocarbon production in PNG.

The relevance of the presented research is determined by the absence of any generally accepted methodology for assessing the economic results of the implementation of ecological management at the Russian enterprises. The introduction of the environmental management system at the enterprises is due to the demand of the world market, which main prerequisites are the tightening of requirements for goods, caused by the globalization processes by foreign consumers. The authors have defined the types of effects obtained by the industrial enterprise as the result of the implementation of the environmental management system. Three main types of effects were analyzed: social, economic, ecological. The research assessed the existing methods of calculating the economic efficiency of environmental measures and determined the possibility of their application for calculating the economic efficiency of the implementation of the environmental management system at the industrial enterprise. The author ’s hypothesis on the existence of an image component of the economic effect in the implementation of the environmental management system at the enterprise is proposed. Prerequisites for implementation of environmental management are considered and comparative analysis of environmental management and environmental control is carried out. The model of the system of implementation and confirmation of environmental management is proposed.

Since a comprehensive understanding of brain function and evolution in vertebrates is often hobbled by the sheer size of the nervous system, as well as ethical concerns, major research efforts have been made to understand the neural circuitry underpinning behaviour and cognition in invertebrates, and its costs and benefits under natural conditions. This special feature of Proceedings of the Royal Society B contains an idiosyncratic range of current research perspectives on neural underpinnings and adaptive benefits (and costs) of such diverse phenomena as spatial memory, colour vision, attention, spontaneous behaviour initiation, memory dynamics, relational rule learning and sleep, in a range of animals from marine invertebrates with exquisitely simple nervous systems to social insects forming societies with many thousands of individuals working together as a ‘superorganism’. This introduction provides context and history to tie the various approaches together, and concludes that there is an urgent need to understand the full neuron-to-neuron circuitry underlying various forms of information processing—not just to explore brain function comprehensively, but also to understand how (and how easily) cognitive capacities might evolve in the face of pertinent selection pressures. In the invertebrates, reaching these goals is becoming increasingly realistic.

Abstract Natural gas, being produced from gas fields around the globe, along with a large number of other harmful substances (CO2, H2S, RSH, COS, etc.), often contains mercury. Mercury’s potentially harmful effect on humans and on the ecological system as a whole as well as the risk regarding mercury’s corrosive effects to the very sophisticated and expensive process material, equipment and catalysts is making its removal an imperative. The frequently applied procedure to remove mercury as an impurity and environment pollutant from process streams utilizes adsorption on a fixed bed consisting of sulfur impregnated activated carbon. This paper deals with data, results and more than seven years of practical field experience obtained by research of mercury removal unit efficiency during production and enhancement of natural gas at Molve, Croatia. Paper details the operating implications of handling and processing natural gas containing mercury, showing the results of the innovative approach in the process control, resulting in safety reliability and process efficiency improvements by plant modification due to change of gas flow direction.

The vast reservoirs of untapped natural gas found in the Greater Gorgon area off Western Australia’s Pilbara coast contain in excess of 11 billion cubic metres (40 trillion cubic feet) of gas, representing some 25% of Australia’s total known gas resources. Developing this world-class resource is a matter of national importance as it would secure Australia’s position as a leading gas producer and provide a huge new source of wealth for both Australia and Western Australia.The key to unlocking the Greater Gorgon reserves is the development of the Gorgon field—one of the largest single gas fields ever discovered in Australia. Establishment of gas processing infrastructure on Barrow Island—which lies between the gas field and the mainland—would provide a catalyst for the future development of other Greater Gorgon area fields. Gas would be processed at that facility and transported through a gas pipeline to shore, enabling large new competitive supplies of gas to be delivered to the mainland.While the development of Gorgon gas would bring significant benefits—A$11 billion investment, A$17 billion in Commonwealth and State taxes and royalties and an annual increase in the nation’s export income of A$2.5 billion—the Gorgon gas field presents some unique challenges. With little associated liquid hydrocarbons, development costs must be kept to a minimum to maintain commercial viability. In addition, Gorgon gas contains a relatively high content of carbon dioxide (CO2) which results in substantial treatment cost and relatively large potential greenhouse gas emissions.Barrow Island—both an internationally important nature reserve and Australia’s largest operating onshore oilfield—has emerged as the development location that would enable gas from the Gorgon gas fields to be competitive in today’s market. The Western Australian Government has said the Gorgon venture (ChevronTexaco, Shell and ExxonMobil) must demonstrate at a strategic level that the proposed Gorgon gas development on Barrow Island can generate economic and social benefits, provide net conservation benefits and mitigate potential on-site impacts.

What are the key design considerations driving the successful delivery of the world’s largest semi-submersible Central Processing Facility (CPF), to be installed at the Ichthys gas field in the Browse Basin, 200 km offshore North West Australia? Extreme cyclonic weather conditions, separating condensate from the gas stream, accommodating 150 personnel, and the sheer size of the gas processing unit at 110,000 tonnes, have created unprecedented challenges for the Ichthys design team. This extended abstract explores the design and planned construction of this massive piece of equipment. The CPF, measuring 110 m x 110 m, will be anchored to the seabed in about 250 m of water using 28 mooring chains. During the 40-year life of the project, the unit will collect gas from a network of up to 50 subsea production wells drilled into reservoirs 4,000–4,500 m beneath the seabed. From the CPF, condensate will be sent to a Floating Production Storage Offtake (FPSO) vessel moored nearby. The gas will be compressed and sent by an 885-km subsea pipeline to Darwin for processing into LNG, LPG and residual condensate. INPEX with its Ichthys joint venturer, Total, will be shipping 8.4 million tonnes of LNG and 1.6 million tonnes of LPG a year, as well as 100,000 barrels of condensate a day at peak. Successful delivery of the Ichthys Project will ensure INPEX achieves its goal of becoming the operator of a major LNG facility, while helping reach its target of producing 800,000 boe/d by 2020.

It is expected that a certain amount of natural gas from Nam Con Son Pipeline No. 2 (Stage 2) which will be received from various new gas fields (e.g. Thien Ung, Dai Hung, Su Tu Trang, Sao Vang, Dai Nguyet) and from an existing Nam Con Son Pipeline No. 1. Besides the current utilisations (e.g. for power generation and fertilizer production), the use of natural gas for petrochemical production have attracted more attention due to a value chain increase and for petrochemical development. In Vietnam, the fertilizer production from natural gas via methane value chain is only used. However, with an estimated capacity of 7-10 milion cubic meter per day (MMSCD) and the ethane concentration of 7-8%, the separation and processing of ethane (200-300 thousand ton per year) is one of potential solution for increasing the gas processing margin. In this study, therefore, an evaluation of ethane gas processing for petrochemical production was conducted based on various marketing, technical and economic aspects. The result revealed that high density polyethylene (HDPE) shows the best scenarios owing to high economic efficiency, well-known technology, high demand but lack of supply. The finding might provide a valuable strategy for deep processing of domestic gas.

Abstract This work investigates the level of noise in oil and gas fields and its impact on the health of the operators, visitors, and trainees, as well as controlling noise within acceptable levels in the workplace by proper measurement. Risk assessment is done to identify the associated hazards of particular activities or tasks in the fields. Sulfur recovery unit (SRU) at a gas processing complex is the case study which consists of three production plants.Many master points were randomly selected, where workers are present. Therefore, in order to sufficiently measure the level of noise, the measurement of the noise level was performed in different periods of time within the years 2014-2017 and was compared with OSHA limits. Results show that most of the gathered noise field data were beyond the permissive limits of OSHA (85 dB). Ishikawa Diagram depicts the analysis of cause and effect of over limits readings which are rotating machines, maintenance activities, steam leakages, fluid flow, and gas flaring.Finally, the risk assessment presents that such workplaces may present a high noise risk score that could harm the workers.

According to the data reported by the international and governmental agencies, the Russian Federation remains one of the world’s major associated petroleum gas (APG) flaring nations. In the past decade, numerous studies have shown the applicability of satellite-based methods to estimate gas flaring. New satellite-based observations might offer an insight in region-, company-, and site-specific gas flaring patterns, as the reported data are often incomplete. We provide a detailed catalog of the upstream and downstream gas flares and an in-depth analysis at the country, region, company and site level of the satellite monitoring results of flaring in Russia from 2012 to 2020. Our analysis is based on the VIIRS Nightfire data and validated against high-resolution daytime satellite images and geographical and geological metadata published by the oil and gas companies and the Russian government. Gas flaring volumes in Russia are estimated to average at 23 billion cubic meters (BCM) annually (15% of global flaring), with 19 BCM (82% on national scale) corresponding to the oil upstream flaring, which has been subject to heavy government regulations since 2013. Despite initially dropping, observed flaring volumes have been on the climb since 2018. We are able to monitor seasonal variations, accidents in gas processing and to track the activities to reduce gas flaring. An effect of gas composition on the flare temperature is reported for oil and gas fields in Russia.
