Pipeline & Flowline Integrity Multiphysics Toolkit
Three simulation beds for pipeline and well-intervention integrity: deterministic transient-pressure reflection inversion with propagated position uncertainty, Bayesian parameter inversion with convergence diagnostics for two physics forward models, and analytical intervention screening calculators. Run the physics, then test it against your own transducer, log or survey data.
Three analysis tools
Pressure Pulse Inversion for Blockage and Deposition Analysis locates reflectors from a closed-valve pressure trace with propagated uncertainty. Bayesian Parameter Inversion fits physics forward models to observed well-log, seismic or pressure data with independent chains, convergence diagnostics and posterior predictive checks. Tubular Lockup Prediction gives the reach of a tubular from trajectory, tubular and friction parameters. Each tool states its assumptions and validity envelope.
Time of flight gives position. Reflection strength gives severity.
A valve slams shut and sends a pressure step up the line at the acoustic wave speed a. Every change in cross-section along the pipe sends part of that step back. A transducer at the valve records the echoes.
If an echo arrives Δt after the initial rise, the reflector sits at x = a·Δt / 2 from the transducer. Its reflection coefficient r = ΔHecho / ΔHstep depends on the area ratio across the feature: for a blockage A′/A = (1 − r)/(1 + r). A leak behaves like a negative reflector.
That is the forward problem in one paragraph. The inverse problem — reading position and severity back out of a noisy trace — is what the Pressure Pulse Inversion for Blockage and Deposition Analysis bed does.
Upload, analyze, keep.
Transducer traces
CSV, TSV or TXT columns of time and pressure from any hammer or valve-slam test. Sampling rate and wave speed are all the inversion needs.
Well logs
LAS or CSV logs with GR, DT, RHOB and NPHI are recognised, plotted as tracks and inverted for porosity and shale volume per zone; DT and RHOB also build the reference model for seismic inversion.
Pressure traces
Time and head or pressure at a closed valve, in m, ft, Pa, kPa, bar or psi, for reflection inversion or full Bayesian transient inversion.
