n: an electric well log in which the conductivity of the formation rather than the resistivity is measured. Because oilbearing formations are less conductive of electricity than water-bearing formations, an induction survey, when compared with resistivity readings, can aid in determination of oil and water zones.

n: a formation or horizon of a well from GAS which oil may be produced. The oil zone is usually immediately under the gas zone and on top of the water zone if all three fluids are present and segregated.

a formation from which oil might be produced.

v: (P&A) to place cement plugs into a dry hole and abandon it.

P&A. Setting cement and mechanical plugs to seal off pays, potential leak points, fresh water zones and the surface.

n: see surface pipe.

n: A large-diameter, relatively low-pressure pipe string set in shallow yet competent formations for several reasons. First, the surface casing protects fresh-water aquifers onshore. Second, the surface casing provides minimal pressure integrity, and thus en

the casing string that protects the fresh water supply. It is always cemented across the water zone and usually extends to surface.

n: a string of casing used to shut off water above an oil sand.

n: Also called intermediate casing,which be used to seal the water zone.

n: the portion of an oil or gas reservoir occupied by water, usually the lowest zone in the reservoir.

n: The comoonent that will expand after meet the water zone.
