1) operation of a lifting device on a wireline to bring well fluids to the surface when the well does not flow naturally. This is a temporary operation to determine whether or not the well can be made to flow or require artificial lift or stimulation to bring oil to the surface.

2) The lowering of the hydrostatic pressure in the hole due to upward movement of pipe and/or tools.
