A continuous flow microwave system based on a transmission line short-circuited waveguide reactor concept is described. The capable of operating in genuine high-temperature/high-pressure process window (310°C/60 bar), applying transparent and chemical resistant cylindrical γ-Al2O3 tube as reaction zone. can be operated an extremely energy efficient manner, utilizing 0.6–6 kW power (2.45 GHz). application the for processing four transformations regime with throughout 3.5–6.0 l/h demonstrated.
The importance of transforming business models and activities toward a sustainable economy is more urgent than ever manifests in the adoption international agreements regulatory initiatives. Company transactions, including mergers acquisitions (M&A), need to pay attention sustainability concepts their implications. Consequently, current traditional literature on M&A processes acknowledges role as prerequisite for success operations. However, reviews relationship between from an...
Sustainability is playing an increasingly important role in analysts' assessments of companies. Companies can address this importance through a sustainability strategy by choosing between independent from the corporate (standalone strategy) or integrating into their (integrated strategy). For purpose, we investigate effects different stages integration on perceptions and buy recommendations. Our results show that analysts favour integrated over standalone strategy. This finding reflected...
ABSTRACT Sustainability performance (SP) has emerged as a central topic on both corporate and political agendas worldwide. This study investigated the relationship between SP financial distress risk (FDR) among European listed firms, addressing growing importance of in decision‐making. Utilising panel dataset from LSEG Data & Analytics (formerly Refinitiv) for STOXX Europe 600 firms 2016 2022, we performed regression analyses to examine impact FDR, measured through alternating scores. In...
Abstract A low concentration chemical treatment has been developed for pumping into a producer from surface to stop water production without harming hydrocarbon production. Matrix reservoirs are the primary target, though upper permeability limit is not yet known. Numerical simulation shown that while such would be universal, many viable targets exist. Horizontal wells and multilaterals can make ideal targets, as vertical in heterogeneous formations hydraulically fractured wells. Key...
Abstract Oilfield iron sulfide (FeS) control and prevention have been mostly proprietary with several disparate solutions. Frequently FeS involves milling, jetting, acid soaking, pulling replacing tubing manually cleaning tanks, vessels, separators pumps. These methods are costly, wasteful strenuous. This paper reviews the latest developments in oilfield researches an attempt to integrate viable solutions expose unworkable practices. In this work, we review evaluate most common summarize...
Abstract Iron sulfide deposition is a ubiquitous phenomenon in sour oil and gas wells presents unique challenges for its control management downhole. The majority of current FeS anti-scale chemical technologies tend to be ‘reactive’ rather than ‘proactive’ downhole scale mitigation, currently there are few inhibitor squeeze options available. following paper details work performed modify an existing novel further enhance inhibition efficacy reconfigure the polymer molecule structure improved...
Abstract Prevention of sulfide scale through the use chemistry is a developing area focus within oil industry. There are few examples single chemical approach working, where inhibitor species function at threshold concentrations. Partial inhibition may be provided by ‘standard’ inhibitors using established chemistries such as phosphonates or polymeric species. However, efficacy these against generally poor and high concentrations typically required. Based on an industry need for true,...
Abstract Synthetic polymers are mainly used at HTHP conditions (>400°F), but there is also an application for them medium temperatures (250 to 350°F) where generally modified natural polymers, synthetic or combinations can be used. These products support fluid loss control and rheology; however, of different add cost complexity the mud system. becoming less robust often a trade-off between good creation negative influence on rheology. This paper details development three new fully...
Abstract Transportation of waxy crude oils and mitigation wax deposition are major challenges especially in regions with cold climate. A viable solution for minimizing organic precipitation fouling pipelines or storage tanks is the use inhibitors dispersants, however, often those pour point depressants (PPDs) have their own due to high product points. To overcome these issues a series active winterized polymer micro-dispersions were developed. Composition physical properties several light...
Abstract Smart scale management techniques are of great demand in nowadays oil and gas industry. The formation zinc, iron lead sulphide scales can cause severe damages production equipment which ultimately results loss productivity.1-4 Currently used materials act inefficient, as high amounts needed, makes research this field demanding.5 However, to develop anti-scaling agents, a deeper understanding the molecular interactions typically polymers is required. To understand occurring...
