...structures and drilling optimization for improved hole cuttings cleaning has been growing along time. As a result, operator companies have been researching and applying different hole cleaning techniques. Some of these are applied as traditional rules of thumb but are not always suitable for the new and up-coming...

This paper presents the methodology and main results of the most recent Norwegian customer survey on consumer valuation of interruptions and voltage problems. The survey provided cost estimates that have been incorporated in the quality of supply regulation, in terms of the cost of energy not supplied...

...of CO₂-mixtures are prerequisites for development of more accurate models and hence more precise design of CO₂ capture and storage (CCS) processes. A literature survey was conducted on both the available experimental data and the theoretical models associated with the transport properties of CO₂-mixtures...

This study investigates the impact of operational fluctuations and uncertainties on the design and expected cost of ship-based CO₂ transport. The model analysis is based on a two-stage stochastic investment model for a single-source single-sink CCS value chain with a ship-based transport system. The...

...base for evaporation of flowing isobutane and propylene in compact internally enhanced surfaces is extended by experimental tests in two microfinned tubes and a smooth tube. The outer diameter for all of the test tubes was 5 mm. Heat transfer coefficient and pressure drop were compared for both fluids...

Remote IT-based support and operations of offshore oil and gas installations are increasing. The technology used to support operations is changing from proprietary closed process control systems to standardize IT systems, connected to internal networks and the Internet. In addition, a network of companies...

...reaction to fire properties, and environmental impact of wooden claddings subjected to treatments modified with TiO₂ and clay nanoparticles. The objective was to investigate the effects of 1 wt% of TiO₂ and clay nanoparticles in existing water-based and stain coatings and preservatives regarding the properties...

...strengths and weaknesses of humans are often missed during the concept and design of complex technical systems. With the focus on digitalization and automation, the human actor is often left out of the loop but needs to step in during safety-critical situations. This book describes how human factors and sensemaking...

...there are few studies on oxidation of HEA and studies on adding oxygen during the fabrication of HEA. In this study we have sputtered thin films of CrFeCoNiCu onto insulating and optically transparent substrates in order to measure structural, electrical and optical functional properties. We have varied...

Mike Batzle and his colleagues has provided a fundamental understanding of mechanisms behind dispersion and attenuation of elastic waves in fluid-saturated rocks. It also has made way for a realization that these phenomena need to be accounted for in a better way when interpreting seismic and sonic data...
