WATER DATA
Calculate Water Resistivity from Water Zone
Electrical Properties A = 0.62 M = 2.15 N = 2.00 unitless
Resistivity of Water Zone RO = 0.9 ohm-m
Neutron Porosity of Water Zone PHINwtr= 0.17 frac
Density Porosity of Water Zone PHIDwtr= 0.15 frac
1: PHIwtr = (PHIDwtr + PHINwtr) / 2 PHIwtr = 0.160 frac
2: RW@FT = (PHIwtr ^ M) * R0 / A RW_1 = 0.028 ohm-m at Formation Temperature
Calculate Water Resistivity from Water Catalog
Temperatures SUFT = 60.0 BHT = 160.0 degF
Depths ZONEDEPTH = 6725 BHTDEPTH = 6562 feet
Catalog Water Resistivity RW@TRW = 0.050 ohm-m TRW = 77 degF KT1 =
1. GRAD = (BHT - SUFT) / BHTDEPTH GRAD = 0.015239 degF/foot
2: FT = SUFT + GRAD * ZONEDEPTH FT = 162.5 degF
3: RW@FT = RW@TRW * (TRW + KT1) / (FT + KT1) RW_2 = 0.025 ohm-m at Formation Temperature
CHOOSE FINAL RW (+RW_1 or +RW_2) RW = 0.025 ohm-m at Formation Temperature
