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: a method of joining steel components in which acetylene gas and oxygen are mixed in a torch to attain the high temperatures necessary for welding. As an early type of welding (it was also called oxyacetylene welding),its primary disadvantage was the seepage of molten weld material onto the interior surface of the pipe, often leading to corrosion problems.

v: to allow cement to mature, or reach a stage harder than that of immediate setting. The process is sometimes called curing. See cure.

n: The percentage of cutting in the annular space carried by drilling fluid.

n: the product of volts and amperes in an AC circuit when voltage and current are measured separately. If voltage and current are not in phase, apparent power is greater than true power.

n: The paper applied asphalt. Used as the container of drilling fluid additive. The best advantage is dampproof and waterproof.

n: any distillation made in accordance with ASTM procedure. Generally refers to a distillation test to determine the initial boiling point, the temperature at which percentage fractionations of the sample are distilled, the final boiling point, and quantity of residue.
