Introduction. GOST R 12.3.047-2012 standard offers a methodology for determination of required fire resistance limits of engineering structures. This methodology is based on a comparison of values of the fire resistance limit and the equivalent fire duration. However, in practice incidents occur when, in absence of regulatory fire resistance requirements, a facility owner, who has relaxed the fire resistance requirements prescribed by GOST R 12.3.047–2012, is ready to accept its potential loss in fire for economic reasons. In this case, one can apply the probability of safe evacuation and rescue to compare distributions of fire resistance limits, on the one hand, and evacuation and rescue time, on the other hand.A methodology for the identification of required fire resistance limits. The probabilistic method for the identification of required fire resistance limits, published in work [1], was tested in this study. This method differs from the one specified in GOST R 12.3.047-2012. The method is based on a comparison of distributions of such random values, as the estimated time of evacuation or rescue in case of fire at a production facility and fire resistance limits for engineering structures.Calculations of required fire resistance limits. This article presents a case of application of the proposed method to the rescue of people using the results of full-scale experiments, involving a real pipe rack at a gas processing plant [2].Conclusions. The required fire resistance limits for pipe rack structures of a gas processing plant were identified. The calculations took account of the time needed to evacuate and rescue the personnel, as well as the pre-set reliability of structures, given that the personnel evacuation and rescue time in case of fire is identified in an experiment.

Production Techniques

Hydraulic fracturing treatments are used to produce oil and gas reserves that would otherwise not be accessible using traditional production techniques. Fracturing treatments require a significant amount of water, which has an associated environmental impact. In recent work funded by the Department of Energy (DOE), an alternative fracturing process has been investigated that uses natural gas as the primary fracturing fluid. In the investigated method, a high-pressure foam of natural gas and water is used for fracturing, a method than could reduce water usage by as much as 80% (by volume). A significant portion of the work focused on identifying and optimizing a mobile processing facility that can be used to pressurize natural gas sourced from adjacent wells or nearby gas processing plants. This paper discusses some of the evaluated processes capable of producing a high-pressure (10,000 psia) flow of natural gas from a low-pressure source (500 psia). The processes include five refrigeration cycles producing liquefied natural gas as well as a cycle that directly compresses the gas. The identified processes are compared based on their specific energy as calculated from a thermodynamic analysis. Additionally, the processes are compared based on the estimated equipment footprint and the process safety. Details of the thermodynamic analyses used to compare the cycles are provided. This paper also discusses the current state of the art of foam fracturing methods and reviews the advantages of these techniques.

In the late 1970’s it was recognised that the seismic provisions of the current NZS 4203:1976 did not readily apply to the types of structures normally used within the land based processing facilities of the “heavy industries” such as petrochemical and oil and gas processing plants impending under the “Think Big” regime. Since the 1984 revision to NZS 4203, there have not been any publicly available New Zealand guidelines on how to interpret the earthquake provisions of the various versions of NZS 4203 (and now AS/NZS 1170) that would update the 1981 publication created by the Ministry of Works for the Ministry of Energy, “Seismic Design of Petrochemical Plants”. There are overseas publications that have considered the differences in the typical structural systems necessary to support the equipment and distributive systems needed to process industrial feedstock. How they behave seismically has been reviewed and recommendations made on the methods to be used to determine the design seismic actions. Such standards as ASCE 7 and FEMA 450 incorporate these in a specific manner relating to the design of industrial plant. With the advent of new oil and gas processing plants in Taranaki, this paper takes the opportunity to review AS/NZS 1170 and adapt these overseas guidelines for the seismic design of new industrial plant in New Zealand. The background for these guidelines will be presented with examples of typical industrial structural systems and their seismic actions. This is with the aim of re-establishing a basis of seismic design for industrial plant within the framework of the new standards AS/NZS 1170.0 and NZS 1170.5.

AbstractThe Breagh Field is in UK Blocks 42/12a, 42/13a and 42/8a. It is a gas field with multiple reservoir intervals within sandstones of the Early Carboniferous Yoredale Formation (equivalent to the Middle Limestone Formation within the Yoredale Group onshore). It was the first and is presently the only field developed within these sandstones, offshore UK. Breagh was discovered in 1997 by well 42/13-2 and proved by development well 42/13a-A1. Its crest is at 7110 ft TVDSS (true vertical depth subsea), marked by the unconformity between the base Zechstein and the subcropping Yoredale Formation. It has a free water level at 7690 ft TVDSS, a maximum column height of 510 ft and a field extent of 94 km2. Breagh was developed using ten wells from a 12 slot normally unattended platform; five of the wells have been stimulated by hydraulic fractures with proppant injection. The unprocessed gas flows through a 110 km 20-inch diameter pipeline to the Teesside Gas Processing Plant. Production started in 2013, reached a peak rate of 150 MMscfgd in 2014 and, by the end of 2018, had produced 140 bcf. The field is operated by INEOS Oil and Gas UK Ltd (70%) with partner ONE-Dyas B.V. (30%).

Gathering system is defined as one or more segments of pipeline, usually interconnected to form a network that transports oil and natural gas from the production wells to one or more production facilities, gas processing plant, storage facility, or a shipping point. There are two types of pipeline networks: radial and trunk system. Produced well fluids are often complex mixtures of the liquid hydrocarbons, gas, and some impurities that can have detrimental effects on the integrity of the gathering pipelines. It is necessary to eliminate most of the impurities before oil and natural gas can be stored and sold. Complexity of the processing facility depends on the treated fluid composition. Environmental impacts during the oil and gas transportation and processing phase will cause long-term habitat changes. To minimize that, it is very important to implement appropriate activities across the designing, construction, operational, and decommissioning phases.

Push for sustainability is evident in areas such as energy generation where the focus has been on finding new deposits to outpace drawdown on existing reserves. Gas flaring is employed by oil and gas industries to burn-off associated gasses from refineries, hydrocarbon processing plants or oil and gas reserve wells. It is one of the most taxing energies and environmental problems challenging the world today. Generally, safety flaring was dubbed as the saviour of process plants and mostly covers for sudden or unplanned plant trips. It is an opportunity to cut greenhouse gases (GHGs) from oil and gas processing plants through flare gas recovery (FGR) process. Oil and gas plants can employ diverse FGR procedures to offset key concerns about the environmental bearing of GHGs emanation most of which necessitating novel apparatus and extraordinary outlay of design and construction. In this study, apart from economic aspects, a real-life case study is extensively analysed to highlight exploration and adoption of optimizing FGR that may be beneficial if flare gas can be recovered, instead of burning. The output of the study may have a significant impact for refineries towards both economic and sustainability towards greening. In a nutshell, this study highlights the efficacy of reducing ‘flare gas system’ towards environment-friendly ‘greening’ aspect as the core of designing.
