n: The process that cement slurry loses free water at permeable strata or perforated interval due to filtration in or after cement slurry displacement.

n: water so thoroughly combined with oil that special treating methods must be applied to separate it from the oil. Compare free water.

n: mud fluids filter loss is very large, free water seeps into unconsolidated formation resulting in layer swelled.

n: 1. water produced with oil. It usually settles out within five minutes when the well fluids become stationary in a settling space within a vessel. Compare emulsified water. 2. the measured volume of water that is present in a container and that is not in suspension in the contained liquid at observed temperature.

1. the excess water that separates from a cement slurry on standing. 2. the first water that separates from the crude oil in the first stage of the separator (free water knockout or FWKO).

the first stage of separation in a crude that contains a large amount of water.

n: (FWKO) a vertical or horizontal vessel into which oil or emulsion is run to allow any water not emulsified with the oil (free water) to drop out.

abbr: free-water knockout.

see Free Water Knockout.

n: (GOV) the total volume of all petroleum liquids and sediment and water, excluding free water. at observed temperature and pressure.
