Gasslaget
Gasslaget is a Norwegian term that literally means the gas layer. It is a descriptive phrase used to refer to a stratified layer of gas within a physical system, and its precise meaning depends on the context in which it appears. In geology and petroleum exploration, gasslaget often denotes the gas cap—the upper part of a hydrocarbon reservoir that contains gas rather than liquid hydrocarbons. The gas cap forms because gas is typically less dense than oil or water, and it can influence reservoir pressure, sealing, and production strategies.
In atmospheric and environmental science, the term can be used to describe a layer of the atmosphere
Overall, gasslaget functions as a general descriptor rather than a fixed technical designation. Its interpretation is
