Abstract The purpose of conducting this LCA was to calculate the potential environmental impacts of the repurposing of John Lawrie Tubulars products sourced from North Sea Oil and Gas fields and to compare repurposed steel tubulars to those made from prime steel1throughout their lifecycle. The analysis includes multiple environmental characterization indicators associated with the material processing, on-site operations, and supply chain. The benefits of repurposed tubulars are consistently beneficial across all environmental indicators when compared to prime steel tubulars. The life cycle analysis results show that for every tonne of steel tubular repurposed there is a 97.21% saving of carbon emissions over a prime steel seamless equivalent and is 97.78% for welded steel tubulars (cradle to gate). Further characterization analysis (cradle to site) showed that distribution presented the highest impact (47%) with materials (26%) and material transportation (15%). The average delivery in the UK adds 56.53kgCO2eto John Lawrie's tubular steel giving a cradle to delivery at the customers gate of 118.53kgCO2eper tonne2. The combined material and distribution carbon footprint of repurposed tubular products (cradle to site) has ~6% of the impact of those made from prime steel. With growing pressure on the construction industry amongst others to be more resource efficient, and to lower embodied carbon, material reuse strategies are critical to meet targets. Considering the potential of the results for environmental impact reduction there is the need to further develop and promote the application of repurposed steel tubulars. This data can be used to demonstrate the environmental impacts and benefits of refurbished tubulars and supports the efficacy of environmental claims and contribution to circular economy. With both the construction and energy industries focused on finding innovative ways in which to reduce their emissions and support the Scottish and UK Governments in bringing all greenhouse gas emissions (GHG) to net zero by 2050, this study details one way these industries can help drive the changes required.

The Impact

Potential environmental benefits have been identified for the utilization of carbon dioxide (CO2) as a feedstock for polyurethanes (PUR). CO2 can be utilized in the PUR supply chain in a wide variety of ways ranging from direct CO2 utilization for polyols as a PUR precursor, to indirect CO2 utilization for basic chemicals in the PUR supply chain. In this paper, we present a systematic exploration and environmental evaluation of all direct and indirect CO2 utilization options for flexible and rigid PUR foams. The analysis is based on an LCA-based PUR supply chain optimization model using linear programming to identify PUR production with minimal environmental impacts. The direct utilization of CO2 for polyols allows for large specific impact reductions of up to 4 kg CO2-eq. and 2 kg oil-eq. per kg CO2 utilized, but the amounts of CO2 that can be utilized are limited to 0.30 kg CO2 per kg PUR. The amount of CO2 utilized can be increased to up to 1.7 kg CO2 per kg PUR by indirect CO2 utilization in the PUR supply chain. Indirect CO2 utilization requires hydrogen (H2). The environmental impacts of H2 production strongly affect the impact of indirect CO2 utilization in PUR. To achieve optimal environmental performance under the current fossil-based H2 generation, PUR production can only utilize much less CO2 than theoretically possible. Thus, utilizing as much CO2 in the PUR supply chain as possible is not always environmentally optimal. Clean H2 production is required to exploit the full CO2 utilization potential for environmental impact reduction in PUR production.

Geological Society Memoir 52 records the extraordinary journey of more than 50 years that has led to the development of some 458 oil and gas fields on the UK Continental Shelf (UKCS). It contains papers on almost 150 onshore and offshore fields in all of the UK's main petroliferous basins. These papers range from look-backs on some of the first-developed gas fields in the Southern North Sea, to papers on fields that have only just been brought into production or may still remain undeveloped, and includes two candidate CO2 sequestration projects.These papers are intended to provide a consistent summary of the exploration, appraisal, development and production history of each field, leading to the current subsurface understanding which is described in greater detail. As such, the Memoir will be an enduring reference source for those exploring for, developing, producing hydrocarbons and sequestering CO2 on the UKCS in the coming decades. It encapsulates the petroleum industry's deep subsurface knowledge accrued over more than 50 years of exploration and production.

Memoir 20 is the most comprehensive reference work on the UK's oil and gas fields available. It updates and substantially extends Memoir 14 (1991), United Kingdom 0il and Gas Fields, one of the Geological Society's best-selling books. This new edition contains updates on many of the ageing giant fields, as well as entries for fields either undiscovered or undeveloped when Memoir 14 was published.The book is divided into nine parts covering the major petroleum provinces both offshore and onshore United Kingdom, from the Gas Basin in the southern North Sea to the Viking Graben in the northern North Sea, from the Atlantic Frontier to the Irish Sea and from the Wessex Basin to the East Midlands. Each part contains a reference map showing field locations. The introductory chapters reveal the stories behind the major plays and discoveries therein, and their tectonic and stratigraphic framework. There are two appendices: tabulated field data and a comprehensive list for all of the UK's 300+ oil and gas fields.

The Lourinhã Formation in the western region of Portugal is an analogue for the Statfjord Formation in the oil and gas fields of the Norwegian Northern North Sea. This petrophysics study encompasses a specific sandstone variety (M variety) of the Lourinhã Formation. This lithic arkose shows an average value of effective porosity of 18.5% and a permeability range of 20–30 mD, and is representative of the distribution range in the petrophysics models of the reservoirs of the Statfjord Formation. The petrographical, physical and mechanical characterization of the M variety sandstone is compared with the main features of the oil- and gas-producing sandstones of the Statfjord Formation in a reference well in the Norwegian Northern North Sea. Efficient enhanced oil recovery (EOR) projects in the oil and gas fields of the Norwegian Gullfaks hub are always needed, and this study intends to provide a contribution to that endeavour.

Any attempt to summarize 25 years of exploration for petroleum in the UK sector of the North Sea must be a daunting task. The outcome, in terms of the oil and gas fields discovered, is the subject of this volume. This introduction will attempt to outline, very briefly, some of the ups and downs of the exploration history which has led the industry to where it stands today, 25 years on (Fig. 1).When the author was at university in the early 1950s the very idea the the United Kingdom would be likely to become a significant, let alone major world producer of petroleum would have been viewed as utterly ridiculousIt is true that oil and gas indications had been encountered in wells and mines in such disparate areas as sussex, the west Midlands and the Midland Valley of Scotland and as seepages in Dorset, Lancashire and West Lothian, but these had been thoroughly investigated without the discovery of any economically significant oil or gas fields. Indeed, the only economic production at that time came from BP's small east Midlands fields based on Eakring where the first discovery had been made in 1939The first Serious attempt to explore for oil in the United Kingdom was initiated in 1918 for strategic reasons, when 11 relatively shallow wells were drilled on anticlinal features in various parts of the country. of these only one, Hardstoft-1 in Derbyshire, discovered producible oil, but attempts to follow up the discovery were unsuccessful.Exploration then

The Impact

The influence of facilities on the foundation made of water saturated ground is studied in view of the impact of various external forces on the foundation. The developed mathematical model of the stress-strained state of the system «facility - foundation» enables to determine maximal stresses and strains occurred in the foundation. The numerical solutions were obtained using the modified finite-element method which took into account the impact of the pore water on the strain characteristics of the ground mineral particles.

Gravitational Anomalies

Based on the analysis of published materials, it is noted that the degree of connection between the indicators of the anomalies of the gravitational field and oil and gas content remains unclear. The aim of the research was to study the nature of the dependence and assess the degree of connection between the size and location of oil and gas fields with gravitational anomalies using the example of the Fergana oil and gas region. To solve this problem, the published material on the geological structure and data on the sizes (effective volume) of deposits, as well as data on deep anomalies of the gravity field in the Fai reduction, were used. The study involved about 70 deposits. Analysis of variance showed that the “influence” of the deep anomaly factor on the effective volume of the fields in the Fergana depression is significant and reliable with a probability of 0.99. At the same time, the share of the influence of this factor on the effective volume of oil deposits in relation to the total impact of all factors is 42%, and for oil and gas - 62%. This testifies to the significant influence of deep subcrustal processes that create corresponding gravitational effects on the formation of the size and location of oil and gas fields in the Fergana depression. According to local gravity anomalies, the impact on the location and effective volumes of deposits is significant, but the reliability is low. The degree of influence on them remains unclear. The results obtained can be used to develop methods for forecasting promising areas for performing high-priority geological exploration works.
