the maximum stress allowed by code or other agreement or study as a fraction of test pressure. Design pressure of the system is related to hoop stress.

n: a meter accessory that enables a meter that is measuring volume at stress temperature to register the equivalent volume at a reference or base temperature.

an engineered sequence of choke settings in the start-up of a well to apply stresses in the formation in a manner that will strengthen the formation and avoid failure.

n: a highly painful and potentially fatal condition in which air or other breathable gases come out of solution in the bloodstream and cause distress or death. So named because the bending joints of the body are most often affected. Also called decompression sickness.

a rheological model used to describe flow in some fluids. Bingham fluids have a linear shear stress, shear-rate behavior after an initial shear-stress boundary has been crossed. Plastic viscosity or PV is the slope of the line. Yield Point is the threshol

describes the relationship between pore pressure and stress

n: The minimum stress when the material fractures in tensile, compressional or cutting condition.

n: bending of pipe that may occur because of hole deviation. Pipe may bend because of the angle of the hole or because of an abrupt deviation such as a dogleg.

n: the ratio of the intensity of stress to the volume of strain produced by stress.
