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.
