n: the prevent sticking joint that connected the top of fishing tool.

n: pressure exceeding or falling below the pressure to be expected at a given depth. Normal pressure increases approximately 0.465 pow1ds per square inch per foot of depth or 10.5 kilopascals per metre of depth. Thus, normal pressure at 1,000 feet is 465 pounds per square inch;at 1,000 metres it is 10,500 kilopascals. See pressure gradient.

n: A formation pressure that deviates from the normal formation fluid hydrostatic pressure. Such pressure may be classified as "subnormal" (lower than normal) or "overpressured" (higher than normal).

n: It is connected above the packer of DST tool, which is used to protect the tubular subs which are installed with bourdon tube.

n: the theory that minerals such as oil and gas are fully owned in place before they are extracted and reduced to possession. Despite this theory, title to oil and gas may be lost by legitimate drainage and by the rule of capture. Also called ownership in place. See rule of capture.

n: the gasoline extracted from natural gas by putting the gas into contact with oil in a vessel and subsequently distilling the gasoline from the heavier oil.

gasoline extracted from wet natural gas by putting the gas in contact with oil.

n: According to the characteristic that different substances absorb different light spectrum, it can be used to investigate and survey the molecule structure, kinds and attribution of the organic compounds.

n: a procedure whereby a product may be subjected to intensified but controlled conditions of heat, pressure, radiation, or other variables to produce, in a short time, the effects of long- time storage or use under normal conditions.

v: to amass or collect. When oil and gas migrate into porous formations, the quantity collected is called an accumulation.

the change in pulsed neutron capture created by acidizing a carbonate. Acidizing increases interconnected porosity and strands chlorides and other ions in the rock.

v: to treat oil-bearing limestone or other formations with acid for the purpose of increasing production. Hydrochloric or other acid is injected into the formation under pressure. The acid etches the rock, enlarging the pore spaces and passages through which the reservoir fluids flow. Acid also removes formation damage by dissolving material plugging the rock surrounding the wellbore. The acid is held under pressure for a period of time and then pumped out, after which the well is swabbed and put back into production. Chemical inhibitors combined with the acid prevent corrosion of the pipe. acid recovery plant n: plant for therecovery of sulfuric acid from acid sludge.
