n: The physicist A. E. Boycott found that the blood cell deposits faster when test tube deflects, especially 40°-50°, than when test tube is vertical. The same situation will be found in the drilling fluid in the horizontal well. That is why people call this

seismic data capable of showing a three dimensional image of the reservoir. Strictly, 3-D is a closely spaced grid of 2-D seismic lines with interpolation to create a seismic cube. The cube can be sliced vertically to create 2-D lines or sliced horizontal

allowable annular surface pressure.

a form of mechanical weathering where loose fragments are transported with water or wind.

n: the density of a solid or liquid substance at a specified temperature. Sometimes referred to as true density or density in vacuo. See density.

n: the force in dynes that a stationary flat plate with a surface area of 1 square centimetre exerts on a similar parallel plate 1 centimetre away and moving in its own plane with a velocity of 1 centimetre per second, the space between the plates being filled with the liquid in question. It is a measure of the resistance that the liquid offers to shear. absolute error n: the difference between the result of a measurement and the true value of the measured quantity as determined by means of a suitable standard device.

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 percentage of the total bulk volume of a rock sample that is composed of pore spaces or voids. See porosity.

the percentage of the total bulk volume that is pore spaces, voids or fractures.

n: total pressure measured from an absolute vacuum. It equals the sum of the gauge pressure and the atmospheric pressure. Expressed in pounds per square inch.

the reading of gauge pressure plus the atmospheric pressure.

n: a hypothetical temperature at which there is a total absence of heal Since heat is a result of energy caused by molecular motion, there is no motion of molecules with respect to each other at absolute zero.

zero point on the absolute temperature scale;equal to -273.16 degrees C, or 0 degrees K (Kelvin),or -459.69 degrees F, or 0 degrees R (Rankine).
