On a world basis, the Norwegian oil and gas industry accounted for 2.5% of the global production in 2020, and even though the CO2 equivalent per unit barrel produced is among the lowest in the world, over 25% of the domestic emissions (scope 1 emissi

It is crucial to ensure that stored CO2 does not leak into the atmosphere. As the last step in the Carbon Capture and Storage (CCS) process, CO2 is injected into underground formations, and it should remain stored there for eternity. However, when re

Annular cement sheath is considered to be one of the most important barrier elements in the well, both during production and after well abandonment. It is however well-known that mechanical damage to the cement sheath might result in leakage pathways

Summary In permanently abandoned wells, cement plugs serve as a well-barrier element that is essential for providing long-term zonal isolation. Poorly plugged wells might provide leakage pathways that pose risks to the surrounding environment. It is

Drilling and completion fluids (muds) are complex suspensions that typically contain weight material (such as barite) to increase the density, and clay particles to increase the viscosity and provide yield stress. In a static column of fluid, barite

Development of geothermal energy sources is an important contribution to ensure the “green shift” from fossil fuels to more sustainable sources of energy. Currently, most geothermal wells operate at temperature range of 150–300° C, but develop

Leakage from CO2 storage reservoirs is a threat towards safe and cost-efficient Carbon Capture and Storage (CCS), and active and abandoned wells have been identified as the most probable leakage paths. This underlines the importance of ensuring well

Leakages of greenhouse gases, such as methane and carbon dioxide from wells, may have considerable environmental consequences. Although much emphasis is currently put on understanding well barrier failures, and thus, preventing well leakages, especia

Debonding of well cement towards casing or rock, i.e. microannuli formation, is a typical failure mode of cement barriers. Consequently, such microannuli may act as leak paths during leakages of downhole fluids such as hydrocarbons or CO2. Current le
