CORE ENGINE

GW-Flow — Wellbore fluid flow simulation

Simulates single- and two-phase flow inside a geothermal well from feedzone to wellhead — capturing pressure drop, friction, slip, and phase change through casing and tubing of varying geometry. Pick an industry flow correlation such as Duns & Ros, then read the full pressure–temperature profile against the wellbore schematic, or sweep a deliverability output curve of flow rate versus wellhead pressure. Used to size new wells, evaluate workover candidates, and predict deliverability under different reservoir conditions.

Integrates with — used as the wellbore engine inside GW-Spinner, GW-Allocation, and GW-History: the same fluid-flow physics drives every well-level calculation in the suite.

GW-Spinner — Feedzone contribution from spinner surveys

Turns raw log-down and log-up spinner passes into clean per-feedzone contributions. It filters cable-speed and pressure spikes, bins the trace with a depth-weighted average, then resolves fluid velocity into corrected speed and mass rate through an XPlot and Means workflow. Because specific volume and mass rate follow the same thermodynamic path as GW-Flow’s pressure-drop engine, the inversion respects realistic friction, slip, and phase behaviour — not just lumped 1D assumptions.

Integrates with — reads the same well file as GW-Flow. Its per-feedzone splits feed naturally into GW-Allocation and GW-History when reconciling well-level flow over time.

GW-Allocation — Rate allocation matched to tracer-flow tests

Reconstructs a well’s continuous flow and enthalpy history from sparse tracer-flow-test (TFT) points. It fits an ellipse decline model to the measured daily wellhead pressure and TFT readings, then history-matches simulated flow and enthalpy across many years — with production time-series, output-curve heatmap, and decline views that show the fit and report bias against the measured data.

Integrates with — builds on GW-Flow output curves and shares a production-matching engine with GW-History, so an allocation run and a baseline history match read the same well and production data.

GW-History — Transient well & reservoir behaviour over time

Extends the wellbore engine in time. It history-matches a well against years of daily wellhead pressure and periodic flow and enthalpy measurements, tracking the long-timescale changes that matter — reservoir pressure and enthalpy decline, scaling, and completion changes. The same production time-series, output-curve heatmap, and decline diagnostics used for allocation reveal how the reservoir’s behaviour shows up in what the well delivers.

Integrates with — calls GW-Flow for each timestep and shares its production-matching engine with GW-Allocation, so a baseline history match and a rate allocation stay consistent on the same well.

GW-Line — Surface piping and thermodynamics

Picks up where the wellhead leaves off — modelling the pipework from each wellhead through gathering manifolds, separators, and toward the power plant. Handles two-phase pressure drop, heat loss, and the thermodynamic state of each stream so you can size lines, plan tie-ins, and quantify the cost of a longer route.

Integrates with — consumes wellhead conditions from GW-Flow / GW-History, and provides plant-inlet conditions back upstream so well-and-line designs can be iterated together.
