Water Saturation Analysis: Archie, Simandoux, Pickett Plot, Buckles & Indonesia Equation
Full Sw toolkit: dual-method calculation, Pickett crossplot with Sw iso-lines, Buckles BVW plot, cementation exponent sensitivity, and Indonesia shaly-sand comparison.
TAGLINE
Full Sw toolkit: dual-method calculation, Pickett crossplot with Sw iso-lines, Buckles BVW plot, cementation exponent sensitivity, and Indonesia shaly-sand comparison.
WHO IT'S FOR
Petrophysicists and reservoir engineers performing water saturation calculations for well evaluation, reserve estimation, or fluid contact determination in clean or shaly sands.
WHAT IT DOES
Calculates formation water saturation using Archie (clean sands), Simandoux (shaly sands), and the Indonesia equation. Builds a Pickett plot with four Sw iso-lines for graphical interpretation, a Buckles BVW irreducible hyperbola plot, and a cementation exponent (m) sensitivity table showing how Sw changes across m=1.5–2.6.
TABS INCLUDED (8)
• Instructions • Inputs & Parameters — well data, Archie params, all 20 depth stations • Archie Sw — F, Ro, RI, Sw per station with colour-coded fluid zones • Simandoux Sw — shaly-sand correction with Vshale input • Pickett Plot — log(PHIE) vs log(Rt) with Sw=0.2/0.4/0.6/1.0 iso-lines • Buckles & BVW — Sw vs PHIE scatter with BVW irreducible hyperbola • Summary — fluid zone counts, average Sw (Archie and Simandoux), average BVW • Archie Parameter Sensitivity — cementation exponent (m) sensitivity, Indonesia vs Archie, Rw from SP log
KEY FEATURES
• Pickett plot iso-lines: colour-coded Sw=20%, 40%, 60%, 100% (log-log axes) • Buckles plot: BVW = PHIE × Sw with adjustable irreducible BVW line • m sensitivity: F, Ro, RI, Sw, and Sw% change for m=1.5–2.6 (base m=2.0 highlighted) • Indonesia equation comparison: side-by-side Sw vs Vshale for 7 clay volumes • Rw from SP log: SSP → Rwe → Rw derivation with formulas
TECHNICAL SPECS
• Excel 2016+ compatible • 1,200+ formulas across 8 tabs • 20-sample dataset classified by Simandoux Sw (oil / marginal / water) • MDT color scheme — input cells light blue, calculated light grey
