The effect is to create turbulence in the fluid flow and distribute the S&W evenly in the flowing stream.

n: the permeability of a pay zone from the bottom to the top of the zone. Compare horizontal permeability.

n: The vertical profile of wellbore of directional well,which can display the measured depth ,vertical depth ,deviation angle and horizontal displacement.

n: The projection of virtual borehole axis on the the vertical plane of designed azimuth line.

n: a clause in an oil or gas lease that excludes, or releases, unproductive formations from the lease at the end of a specified period.

n: a cylindrical separator standing up- right, perpendicular to the ground.

n: a pre-established location in the vertical plane along the tank shell couesponding to a given horizontal station. Compare horizontal station.

n: (VSM) an Hshaped device that supports a pipeline above the ground. Vertical support members are used in parts of the world where frozen earth prevents normal burial of the line. See lowering-up.
