n: the measured 10-minute gel strength of a fluid is the maximum reading (deflection) taken from a direct-reading viscometer after the fluid has been quiescent for 10 minutes. The reading is reported in pounds/100 square feet. See gel strength.

n: a system of devices installed on a floating offshore drilling rig to maintain a constant tension on the riser pipe, despite any vertical motion made by the rig. The guidelines must also be tensioned, so a separate tensioner system is provided for them.

n pi: vessels used as secondary standards for volume measurements.

n: the working pressure of a container or vessel times a safety factor. See also working pressure.

n: 1. in geology, the line connecting the lowest points along a stream bed or valley. Also known as a valley line. 2. a line crossing all contour lines on a land surface perpendicularly.

n: The working regime that determining hydraulic parameters and delivery capacity
according to maximum jet velocity in jet drilling .

n: The liquids volume that bump should supply theoritically per unit time.

n pi: the content of liquefiable hydrocarbons in a volume of gas, determined from analyses or tests of the gas.

n: the volume of residue that theoretically remains after volume reductions attributable to the processing of a volume of gas in a plant. It is determined by applying a factor from a table or calculation to the volume of gas delivered to the plant.
