Drive Mechanism Identifier — Drive Indices, GOR/WOR Diagnostics & Dykstra-Parsons Coefficient
PRICE
$59 USD — one-time purchase
TAGLINE
Identify your reservoir energy source from production history, benchmark recovery factors by mechanism, and quantify permeability heterogeneity with the Dykstra-Parsons coefficient.
WHO IT'S FOR
Reservoir engineers performing reservoir surveillance, production performance analysis, or decline diagnostics who need to understand reservoir energy and heterogeneity.
WHAT IT DOES
Calculates normalised solution gas, gas cap, and water drive indices from production and pressure data (Craft & Hawkins method). Tracks GOR and WOR trends as diagnostic indicators. Classifies the dominant drive mechanism per period. Benchmarks expected recovery factor ranges from SPE literature. Calculates the Dykstra-Parsons coefficient (V_DP) as a permeability heterogeneity measure.
TABS INCLUDED (12)
• Instructions • Production Data — 10-period rate, GOR, WOR, pressure history • Drive Index Calc — Eo, Eg, Efw energy terms; normalised DI per period • Diagnostics — GOR/WOR trend plots and anomaly flags • Mechanism Summary — dominant drive per period; confidence rating • Drive Indices — stacked bar chart data (solution gas / gas cap / water) • GOR & WOR Analysis — monthly GOR trend with warning thresholds • Pressure vs Np — depletion rate diagnostic • Drive Classification — mechanism ID: pure/mixed/combination drive • Summary Dashboard — current dominant drive, RF estimate, recommended action • Recovery Factor by Drive — SPE benchmark RF ranges with your reservoir estimate • Dykstra-Parsons Coeff — V_DP from 20-layer k data; heterogeneity classification
KEY FEATURES
• RF benchmarks: solution gas 8–20%, gas cap 20–35%, water drive 35–55%, gravity 50–70% • Dykstra-Parsons: V_DP = 1 − (k84.1/k50); five-category interpretation from homogeneous to extremely heterogeneous • Drive index: DI_SG + DI_GC + DI_WD = 1.0 per period by definition
TECHNICAL SPECS
• Excel 2016+ compatible • 120 formulas across 12 tabs • 10-period dataset; 20-layer permeability data for Dykstra-Parsons • MDT color scheme
SHOP COPY
