The construction of the Hestnes railroad tunnel in southern Norway, used an innovative pre-excavation grouting (PEG) methodology to achieve a functionally dry tunnel surface of the rock support lining. The final tunnel design was reconsidered, omitting the originally planned cast-in-place concrete...

Comprehensive analysis to securing software updates for IoT devices, a critical aspect of maintaining trust and security in IoT ecosystems. It explores the challenges of managing updates in dynamic IoT environments and introduces a novel approach using Digital Twins to enhance the software update...

Many advanced geothermal systems require drilling deep connected closed loop wells. These wells are connected by a series of parallel horizontal well sections pairs for heat transfer from the formations. The separation of these wells, and the distance between them, must be controlled in the drilling...

Viscosity models are needed to present input parameters for hole cleaning and other well hydraulic items. The simplest model describing the drilling and completion fluid adequately at shear rates valid for most well geometries and pump rates is the Herschel-Bulkley model, which is a three-parameter...

Drilling and well construction is one of the main cost drivers for offshore field development. Drilling new wells is also needed during the field production life. Drilling offshore wells are normally limited to the availability of free slots in the subsea template. Subsea slot recovery for...

Different methods to handle oil wet drill cuttings in a field development offshore Canada has been evaluated. The governing requirement is an upper limitation of 6,9% oil on cuttings for discharge to sea when an environmentally acceptable base oil is chosen. Methods that ensure that cuttings remain...

Selecting the right drilling fluid for an offshore well is a challenging exercise. Both because a drilling fluid needs to have a set of properties which must satisfy different and often conflicting requirements, and also because relating properties as measured in a lab to actual downhole performance...

Social AI services like ChatGPT and My AI are increasingly integrated into the lives of young people. Despite this growing use, there is limited research on how youth perceive and engage with social AI in their everyday social lives, as well as the broader social implications of such engagement. To...

This article is concerned with the issue of how Research Performing Organizations can balance the market and non-market values of the research data they hold. To address this issue, we adopt the lenses of the Resource Based View and Open Science and explore the interplay between them. In doing so...

Denne rapporten dokumenterer fase en i Sintef og Nord Universitets følgeforskning og evaluering av arbeidet med utvikling og utprøving av ‘Bygdevekstavtaler’ som et nytt distriktspolitisk virkemiddel for små kommuner i sentralitetsklasse fem og seks. Rapporten oppsummerer status etter Fase...

Chapter highlights – Provides a blueprint for leveraging transition design to create more inclusive experiences of outdoor activities. – Extends the understanding of transition design by demonstrating its applicability in tourism by applying such a design process. – Develops prototypes aimed at...
