WellSim — Nodal Analysis

Lift type (one active) Natural flow Gas lift ESP

Layers (one active) Single layer (default) Multi-layer (optional)

Production test (optional)

Sensitivities

VLP parameter sets (blank = base value)

Future reservoir pressures, psi

Reserve estimate — material balance (workbook: oil reserve estimate)

Well data, marches and the matched IPR are taken from the Well model module.

1. Prod data & macro (Pres solver) 2. Static Pres history (memory gauge) 3. Reservoir limit (constant rate)

prod_data — inputs green (GOR/WC blank = base), outputs dt / pr / z filled by the solver

or click a cell and Ctrl+V (Date, FTHP, q, GOR, WC, Pwf)

Forecast — Tarner (saturation-tracking MB + nodal)

Well data, marches and the matched IPR are taken from the Well model module; N and the start state chain off the Reserve module (grey = calculated).

Forecast Pwf source (one active)

Nodal at forecast FTHP (VLP-coupled) Fixed minimum Pwf (workbook)

Gas lift

Performance curve sweep

ESP

Pump ΔP and tubing gas are direct inputs for now — the pump-catalog, intake/separator and matching solver arrive with the ESP stack.

IPR — Darcy Pr² is the main J Darcy Pr² (default) C & n (calculated)

Layers (one active)

Single layer (default) Multi-layer (optional)

Multi-rate test (Pwf blank → get Pwf from THP)

Sensitivities

VLP parameter sets (blank = base value)

Future reservoir pressures, psi

Reserve estimate — p/Z (workbook: gas reserve estimate)

Well data, marches and the matched IPR are taken from the Well model module.

1. Prod data & macro (Pres solver) 2. Pres from SITHP 3. Reservoir limit (constant rate)

prod_data — inputs green (CGR/WGR blank = base), outputs dt / pr / z filled by the solver

or click a cell and Ctrl+V (Date, FTHP, q, CGR, WGR, Pwf)

Forecast — p/Z tank + nodal

Well data, marches and the matched IPR are taken from the Well model module.
