Geosteering is the technique of guiding directional drilling to remain within the pay zone. This process demands a thorough survey of the lithological properties of the surrounding geo- logical strata. Since logging while ...

Permanent plug and abandonment (PP&A) of wells is steadily becoming more important on the Norwegian Continental Shelf (NCS), as a large number of fields are approaching end of their productive life. Combining operational, ...

Drilling fluids are essential for drilling operations and serve many important functions. To maintain control of the wellbore, while ensuring sufficient cutting transportation, good understanding of the rheological properties ...

Denne oppgaven presenterer utviklingen av nye tetthet- og hastighets- regresjonsmodeller (enkel- og multivariate-baserte) og artificial neural network (ANN) basert modellering ved bruk av data hentet fra Barentshavet, ...

The oil and gas industry continuously enters a phase with new challenges and new ways of thinking, the rise of a digitalization revolution can be the key answer to creating new opportunities to overcome the industry's ...

The oil and gas sector in the North Sea is mature and consists primarily of brownfields that have passed their peak production or are close to the end of their lives. Many of these fields will have to be abandoned in the ...

Enhanced Oil Recovery (EOR) and the effect of the aqueous chemistry on the mechanical strength of chalk have been extensively studied over the years. This is simply because the stability of the reservoir system is affected ...

In the past years there has been an increased focus on decommissioning of wells in the NCS. Decommissioning of wells introduces significant investments with no financial returns and has for those reasons historically had ...

Hydrogen sulphide production can prove to be a very costly affair for exploration and production companies. Failure to implement efficient H2S control and mediation strategies can lead to a decrease in production assets, ...
