Where IQL fits
Between nodal analysis and full reservoir simulation
Production technologists choose between two imperfect tools today. Nodal-analysis software (Prosper, Pipesim, NETool) is fast, but treats the reservoir as a single inflow point or a steady-state snapshot. Full reservoir simulators (Eclipse, CMG, Intersect) capture the reservoir, but need days of grid-building and a reservoir-engineering specialist.
IQL sits in the gap. Reservoir-coupled physics, native valve support, and multi-period time evolution, with screening sweeps in seconds per case.
What IQL adds
- Reservoir physics, not an assumed PI
- Multi-period schedules, not single snapshots
- Native inflow control valve dispatch, not manual VLP tables
- Mechanistic VFP generation built in, no extra license
- Two solver engines that cross-validate each run
How IQL solves
Two solver engines, cross-validating each run
IQL exposes two reservoir engines side-by-side, coupled to the same outflow system. They typically agree within 1 to 2 bar BHP, a built-in confidence check on every run.
Engine 1
Analytical line-source
Picard iteration, line-source per zone
- Speed: seconds per case
- For: screening sweeps, sensitivity studies, multi-period schedules
Engine 2
Numerical 3D finite difference
Newton-Schur, full 3D Peaceman
- Speed: minutes per case
- For: heterogeneity, pressure transients, depletion, verification
What you do with IQL
From screening to surveillance, in hours
IQL is built for the questions that fall through the cracks of conventional toolchains: too coupled for nodal analysis, too quick-turn for a full simulator.
Concept screening across dozens of designs
Test ICDs, AICDs, AICVs, and passive completions for the same reservoir. Rank by surface deliverability, water cut, and cumulative production, not idealised sand-face numbers.
Multi-year production forecasting
Run a multi-period schedule with BHP, rate, or THP control. Per-zone water cut and gas fraction evolve over time. Generate the full production profile in one run instead of stitching steady-state snapshots.
Nozzle sizing and compartment-length sensitivity
Bracket how sensitive recovery and water cut are to nozzle size and packer spacing. Understand where the design has headroom and where it is knife-edge before carrying it forward.
Post-installation surveillance
Diagnose anomalies on wells already in production. Forward-simulate per-zone behaviour, hypothesise what zone is producing what, and test remediation strategies before scheduling intervention.
VFP-table generation for any reservoir simulator
Generate Eclipse VFPPROD tables in place using the integrated Flowpro MPF v7 mechanistic multiphase model. No separate license, no extra workflow step, no place for inputs to drift.
Sand-control and completion-type trade-offs
Compare stand-alone screens against cased-and-perforated or frac-pack alternatives under the same reservoir and production conditions. Quantify the cost-benefit before committing.
Built in
Reservoir, valves, and outflow as one system
The value of inflow control completions only shows up when the model honours the full system. IQL solves reservoir deliverability, valve flow restriction, multi-zone water and gas evolution, liner friction, and tubing-to-surface lift in one coupled run.
- Native valve dispatch per zone (ICD, AICD, AICT, SAS, VFP-table) with no manual VLP-table assembly
- Multi-period schedules with BHP, rate, or THP control across the full forecast horizon
- Per-zone water cut and gas fraction evolution, time-interpolated and rate-weighted
- Mechanistic VFP generator powered by Flowpro MPF v7, with OLGA-S, Beggs-Brill, Hagedorn-Brown, Ansari, Aziz, and Xiao correlations for cross-comparison
- Compare Cases workflow: overlay rate, cumulative, water cut, BHP, and fractions across multiple cases in a single chart
- Stochastic permeability generator (log-normal Dykstra-Parsons) for heterogeneity studies on the numerical engine
Coexists with
Fits alongside the tools you already run
IQL doesn't replace nodal analysis or full-field simulation. It fills the gap between them and feeds clean inputs to both.
Prosper, Pipesim
IQL adds reservoir physics underneath the well, native inflow control valve support, and multi-period time evolution. Use IQL where the well has zones; use Prosper or Pipesim for network-level production technology.
NETool
NETool is the right tool for single-point design freeze. IQL handles everything around it: screening before the design is locked in, multi-year forecasting after, and post-installation surveillance. The two cover different decision points; most teams want both.
Eclipse, CMG, Intersect, Reveal
IQL exports VFPPROD tables straight into your reservoir simulator. Use IQL for production-technology speed; escalate to the full-field simulator for field-scale forecasting and history matching.
Insight
When annulus phase segregation, valve interaction physics, or upscaled inputs for full-field simulation matter, Insight is the next step. IQL screens and surveys; Insight rigorously designs.
