Description of a reservoir interval.

Table 12.11.34-1 Attributes
Name	Type	Notes
ExtensionNameValue	ExtensionNameValue	Extensions to the schema based on a name-value construct.
FormationPermeability	PermeabilityRockMeasure	Permeability of the formation.
FormationPorosity	VolumePerVolumeMeasure	Porosity of the formation.
GrossPayMdInterval	MdInterval	Measured depth of the bottom of the formation.
GrossPayThickness	LengthMeasure	The total thickness of the interval being treated, whether or not it is productive.
LithFormationPermeability	PermeabilityRockMeasure	Formation permeability, a measurement of the ability of a fluid to flow through a rock. Commonly measured in milliDarcys (1m2 = 0.000000000000986923 Darcy).
LithMdInterval	MdInterval	Lithology measured depth interval.
LithName	String2000	A name for the formation lithology.
LithNetPayThickness	LengthMeasure	Net pay is computed. It is the thickness of rock that can deliver hydrocarbons to the wellbore formation.
LithPoissonsRatio	DimensionlessMeasure	The ratio of the relative contraction strain, or transverse strain (normal to the applied load), divided by the relative extension strain, or axial strain (in the direction of the applied load).
LithPorePres	PressureMeasure	Refers to the pressure of fluids held within a soil or rock, in gaps between particles’ formation porosity.
LithYoungsModulus	PressureMeasure	Young's modulus (E) is a measure of the stiffness of an isotropic elastic material. It is also known as the Young modulus, modulus of elasticity, elastic modulus (though Young's modulus is actually one of several elastic moduli such as the bulk modulus and the shear modulus) or tensile modulus. It is defined as the ratio of the uniaxial stress over the uniaxial strain.
NameFormation	String2000	Name of the formation.
NetPayFluidCompressibility	IsothermalCompressibilityMeasure	The volume change of the fluid in the net pay when pressure is applied.
NetPayFluidViscosity	DynamicViscosityMeasure	With respect to the net pay, a measurement of the internal resistance of a fluid to flow against itself. Expressed as the ratio of shear stress to shear rate.
NetPayFormationPermeability	PermeabilityRockMeasure	The permeability of the net pay of the formation.
NetPayFormationPorosity	VolumePerVolumeMeasure	The porosity of the net pay formation.
NetPayName	String2000	The name used for the net pay zone.
NetPayPorePres	PressureMeasure	The pore pressure of the net pay.
NetPayThickness	LengthMeasure	The thickness of the most productive part of the interval. Net pay is a subset of the gross.
uid	String64	Unique identifier for this instance of StimReservoirInterval
