Reservoir summation module to compute averaged and lumped properties in zone intervals along borehole
Channel created during lump processing to indicate pay zones
Name of curve used as discriminator 1
Cutoff value for first discriminator curve
Cutoff comparison operator for discriminator 1: >, =>, <. <=...
Name of curve used as discriminator 2
Cutoff value for second discriminator curve
Cutoff comparison operator for discriminator 2: >, =>, <. <=...
Cutoff value for first discriminator
Cutoff value for second discriminator
Porosity of an interval averaged over the gross thickness
Total thickness of the interval, after applying any discriminator cutoffs specified as Initial.
Maximum value of Gamma Ray
Cutoff value for GR curve
Maximum value of Shale/Clay volume fraction
Cutoff value for Vshale or Vclay curve
Cutoff value for Water Saturation curve
Minimum net thickness; beds thinner than this do not contribute to Net Thickness. See MIN_NON_NET_THICKNESS
Minimum non-net thickness; if isolating shale beds are thinner than this, the sand they isolate is considered to contribute to Net Thickness.
Cutoff value for Permeability curve
Cutoff value for Porosity curve
Fraction of the summation interval for which data to apply "Net" cutoff criteria are unavailable.
Ratio of Net_Thickness to Gross_Thickness
Average clay volume fraction in the net pay portion of the zone interval (thickness weighted arithmetic average).
Fraction of the summation interval for which data to apply "Net_Pay" cutoff criteria are unavailable (including the fraction for which "Net" or "Net_Reservoir" criteria are unavailable).
Average flushed zone water saturation in the net pay portion of the zone (thickness weighted arithmetic average).
Ratio of Net_Pay_Thickness to Gross_Thickness
Total Net Pay hydrocarbon porosity-thickness for all zones; that portion of Net_Pay_Porosity_Thickness which is hydrocarbon-filled.
The net pay moved hydrocarbon volume multiplied by the net pay thickness; the portion of Net Pay Porosity Thickness filled with moved hydrocarbons.
Net pay moved hydrocarbon volume fraction: moved oil saturation (Sxo-Sw) in the net pay of the zone multiplied by the net pay average porosity.
Average permeability in the net pay portion of the zone interval (thickness weighted arithmetic average).
Thickness of the permeable net pay portion of the zone i.e., the product of the Net Pay Thickness and Net Pay Average Permeability
Porosity of the Net Pay zone
Total net pay porosity-thickness of the zone interval: the product of Net Pay Thickness and Net Pay Average Porosity
Net Pay thickness, i.e. thickness after applying Shale, Porosity and Water Saturation cutoffs
Average water saturation in the net pay portion of the zone (thickness weighted arithmetic average).
Average volume fraction of clay in the Net Reservoir portion of the zone (thickness weighted arithmetic average).
Fraction of the summation interval for which data to apply "Net_Reservoir" cutoff criteria are unavailable (including the fraction for which "Net" criteria are unavailable).
Average flushed zone water saturation in the net reservoir portion of the zone (thickness weighted arithmetic average).
Ratio of Net_Reservoir_Thickness to Gross_Thickness
Average permeability in the net reservoir portion of the zone interval (thickness weighted arithmetic/geometric/harmonic average).
The product of the Net Reservoir Thickness and Net Reservoir Average Permeability.
Average porosity in the Net Reservoir portion of the zone (thickness weighted arithmetic average).
Total pore thickness of the zone; i.e. the product of Porosity and Net_Reservoir_Thickness.
Total thickness of the porous portion of the zone; i.e. the footage which satisfies the Net Thickness conditions and which has porosity suitable to be a potential reservoir.
Average water saturation in the net reservoir portion of the zone (thickness weighted arithmetic average).
Shale thickness: difference between Gross Thickness and Net Thickness
Total Net thickness, i.e. thickness after applying Shale cutoff
Method used for averaging permeability - ARITHMETIC or GEOMETRIC
Name of curve used as permeability cutoff
Name of curve used as porosity cutoff
Name of user project
Percentage of sand (non shale)
Percentage of shale
State or Province
Name of curve used as water saturation cutoff
