usually another set of natural fractures in the pay oriented at some angle to the primary natural fractures.

n: a power line from the lease distribution point to electrical awaratus on the lease.

n: movement of hydrocarbons, subsequent to primary migration, through porous, permeable reservoir rock, by which oil and gas become concentrated in one locality.

n: porosity created in a formation after it has formed, because of dissolution or stress distortion taking place naturally, or because of treatment by acid or injection of coarse sand.

non intergranular porosity such as fractures, vugs, etc. that may contribute sharply to permeability but may not significantly raise the porosity level.

n: 1. the use of waterflooding or gas injection to maintain formation pressure during primary production and to reduce the rate of decline of the original reservoir drive. 2. waterflooding of a depleted reservoir. 3. the first improved recovery method of any type applied to a reservoir to produce oil not recoverable by primary recovery methods. See pressure maintenance, primary recovery.

a recovery improvement process such as water flooding or gas flooding.

n: sediment that does not show up in an untreated sample of emulsion but that does appear as additional water in a sample treated with a slugging compound. Compare primary sediment.

n: a standard die value of which is fixed by direct or indirect comparison with a primary standard or by means of a reference-value standard. Compare primary standard. working standard
