The intersection of a wellbore with a reservoir

Gently undulating, almost featureless plain that, in principle, would be produced by fluvial erosion that would, in the course of geologic time, reduce the land almost to baselevel (sea level), leaving so little gradient that essentially no more erosion could occur

Living or growing near the surface of the ocean; Marine sediments derived from floating organic matter (e.g., plankton) that accumulates on the seafloor; Pelagic sediments are ocean sediments that accumulates far enough from land that detrital materials are a minor component. These sediments are largely composed of tiny shell debris

Pertaining to processes that add, transfer, transform, or remove soil constituents
