12.11.28 StimPerforationCluster

Information about a set of perforations. The assumption is that all perforations within a given set are created with the same device or method.

Table 12.11.28-1 Attributes
Name	Type	Notes
DensityPerforation	ReciprocalLengthMeasure	The number of perforation holes per length across the treatment interval. Used to describe but not limited to the configuration of perforating guns or the placement of perforations (holes, slots, openings, etc.) in the wellbore, and is often abbreviated to spf (shots per foot).
DischargeCoefficient	double	A coefficient used in the equation for calculation of pressure drop across a perforation set.
FrictionFactor	double	The friction factor of each perforation set.
FrictionPres	PressureMeasure	The friction pressure for the perforation set.
MdPerforatedInterval	MdInterval	Measured depths of the top and base perforation.
PerforationCount	NonNegativeLong	The number of perforations in this interval.
PhasingPerforation	PlaneAngleMeasure	The radial distribution of successive perforations around the wellbore axis. Radial distribution is commonly available in 0, 180 120, 90 and 60 degree phasing.
Size	LengthMeasure	The size of the perforations.
TvdPerforatedInterval	TvdInterval	True vertical depth of the top and base perforation.
Type	String64	The type of perforation and/or how the perforation was created.
