Neqsim Olga Multiphase Simulator · equinor bundle
Run the OLGA transient multiphase flow simulator from Python: locate the installation, generate its PVT table and hydrate equilibrium curve from a NeqSim fluid, validate a genkey case with a rule check, launch the batch engine with the right flags, decode the engine exit code, and read .tpl trend and .ppl profile results. USE WHEN: a task must execute an OLGA case, batch or sweep OLGA runs, build a two- or three-phase OLGA PVT table or a HYDRATECURVE for HYDRATECHECK, diagnose an OLGA failure or licence error, or benchmark OLGA against the NeqSim pipeline models (TwoFluidPipe, PipeBeggsAndBrills) so that a multiphase flow result can be quoted with a known accuracy.

Neqsim Reference Fluid Synthetic Generation · equinor bundle
Public helpers to generate representative or synthetic fluid cases from a common reference fluid by adjusting a split/characterization factor, match that factor to measured PVT/separator data, blend well/fluid compositions into a field composition by molar-rate allocation, and — when there is NO PVT report and possibly no sample at all — build a declared best-guess fluid basis from fundamentals and named analogues: reservoir temperature from a provincial geothermal gradient, fluid type from GOR/degAPI bands, GOR and stock-tank gravity interpolated on an analogue depth trend with low/base/high cases, a seed light-ends + C7+ cut composition ready for a NeqSim EOS characterization, a per-parameter provenance and assumption register, and a ranked data-acquisition plan.

Neqsim Reservoir Model Builder · equinor bundle
Set up a screening-level reservoir model from whatever data exists, on a data-maturity ladder from a single public headline volume up to a full static-model parameter set, and refine it as data arrives. Enforces a data-first workflow: six modelling ingredients (geometry, petrophysics, fluid, SCAL, contacts, volumes) each have a ranked source ladder, every rung above the one in use must carry a recorded outcome of used/blocked/absent before the model may be built, a blocked source is reported as an access request rather than an acquisition programme, and any downgrade is surfaced with what it gave up so recovery factor can be decomposed into displacement times sweep. USE WHEN: a task needs a reservoir model for a field where only open data is available (for example an NCS field on public resource pages), needs a best-guess structural model when there is NO seismic, log or contact data at all (assumed play-typical trap style, layered stratigraphy, fluid contact and culmination solved to honour published volumes
