a profile ring in the tubing with a very small opening that allows flow but stops any equipment or tool from passing through the restriction. May be small I.D. or pinned.
a pressure drop vs. flow study, using a computer program that compares flow performance at various “nodes” along the flow path.
n: 1. an unwanted component of a signal that obscures the information content. 2. any spurious voltage or current arising from external sources and appearing in the circuits of a device.
n: a kinds of logging method that records the motion voice of fluid in cement channle and out of casing.
A sound recording downhole. Best performance of noise logs is with gas flow. Gas flow can be heard to about 10 actual ft3/D (Note – not standard ft3/day). At very low gas flow rates (q<400 actual ft3/D),gas flow can be estimated from millivolts of noise
a log-log plot that is very useful in predicting when the fracture is in tip-screen-out mode and whether the fracture is being widened or height growth is occurring.
n: nominal height of tower derrick refers to the vertical height from the back plane of derrick leg base plate to the back plane of crown beam. nominal height of open front and A type derrick refers to the vertical height from the center of derrick back plan
n: nominal height of racking paltform refers to the vertical height from the back plane of derrick leg base plate to the back plane of money board.
n: a designated size that is very close to, but that may be different from, the actual size.
n: the quantity assigned to a tank or vessel for the purpose of identification only;the exact volume may be some what different from the nominal volume.
n: a chart that presents an equation containing a number of variables in the form of several straight lines. The straight lines are scaled with values of the variables. To use it, a straight edge is placed across the scaled lines at the appropriate values. A monograph can be easier to use than solving the equation.
n: the graph that nomography needs.
