Report which OPM binaries and Python bindings the server can reach.

Use this first when troubleshooting — it tells you whether wsl.exe is reachable, whether flow and ResInsight respond, and whether the python3-opm-common bindings import successfully inside the distro.

Scan a directory tree for simulation cases (.DATA decks and .SMSPEC results).

The session opener: returns case names, deck paths, whether results exist, and modification times (newest first).

Translate a Windows path to its WSL equivalent (C:\x → /mnt/c/x).

Translate a WSL path back to its Windows form.

Parse an ECLIPSE/Flow DATA deck and report keyword counts + parser issues.

High-level deck summary: phases, units, grid dimensions, wells, schedule length.

List wells declared in the deck at the first schedule step.

Numbered text slice of a deck (or one of its include files) — no WSL needed.

Decks are plain ASCII; use this instead of host-shell head/sed when a client misdetects .DATA as binary. file selects an include file by path or bare name (matched against the resolved INCLUDE tree).

Regex search across a deck AND its resolved INCLUDE tree (PATHS-aware).

The deck-QC workhorse: deck_grep(deck, "^WCONPROD|^LIFTOPT", context=8) returns file, line number, and context for every keyword hit — including keywords that live in include files referenced via $ALIAS paths. Files larger than ~8 MB (bulk GRDECL arrays) are skipped and reported.

Start an OPM Flow simulation in the background; returns a job id immediately.

extra_args is a JSON array of flow flags, e.g. ["--enable-tuning=true"] — a plain string is also accepted and split shell-style. At most OPM_MCP_MAX_PARALLEL jobs run at once — extra submissions are state="queued" and launch automatically as slots free. By default writes INFOSTEP/INFOITER diagnostics so flow_convergence_report works (convergence_info="none" to skip). mpi_processes=N runs mpirun -np N for distributed solves.

Check whether a Flow job is still running, with the latest progress line.

Return the tail of a Flow job's combined stdout/stderr log.

grep (case-insensitive regex) filters the WHOLE log first and returns the last lines matching lines with line numbers — e.g. grep="will be shut|Problem:|Error:" extracts well-shut and solver events from a long run.

Cancel a running Flow job.

List recent Flow jobs known to this server.

List summary vector keys in a case. Optional glob pattern (case-insensitive).

Read one or more summary vectors as time series, downsampled to max_points.

keys is a JSON array (["FOPR", "WBHP:B-1H"]); a comma/space separated string is also accepted.

Field-level KPIs: cumulative production/injection, pressure, final rates.

Per-well KPIs: oil/gas/water rates, BHP, cumulative production.

Static grid info: dimensions, active count, porosity/permeability stats.

List report steps available in a UNRST file plus the keywords it contains.

Compare two cases on field totals (or supplied keys). Default = FOPT/FGPT/FWPT/FPR.

Plot summary vectors to a PNG, rendered inline in the chat.

Keys accept wildcards (WWCT:*, GOPR:*) as a JSON array; a comma/space separated string also works. Twin y-axis groups by engineering unit; x_axis is "date" or "days". No ResInsight/OpenGL needed — the fast path for rate/pressure/cumulative plots.

I–J areal map of a grid property for one K layer, rendered inline.

Dynamic (PRESSURE/SWAT/SGAS/SOIL from UNRST at a report step, default last) or static (PORO/PERMX/NTG/PORV from INIT). Inactive cells blank; axes are 1-based I/J. The no-GL alternative to a ResInsight view for sweep/depletion QC.

Field MB QC: OOIP, recovery factor, exact oil mass-balance drift, surface VRR.

Solver performance from INFOSTEP/INFOITER: time by stage, wasted steps, worst steps.

Per-layer stats for a dynamic property (PRESSURE/SWAT/SGAS/SOIL) at a report step.

History-match QC: misfit (RMSE/bias/MAE/NRMSE) of simulated vs observed data.

CSV: first column date (ISO), remaining headers are summary keys (WBHP:PROD, FOPR, ...); blank cells = no observation. Returns per-key stats and an inline sim-vs-obs overlay plot.

RFT surveys (pressure vs depth at well connections) from CASE.RFT.

For perforation-pressure / gradient QC. Requires WRFTPLT in the deck's SCHEDULE section. Cell i/j/k are 1-based.

Clone a deck with safe text overrides (append_before_end / replace_regex / set_title / insert_after_keyword).

Writes a NEW deck, reports per-op substitution counts, and re-validates. Idiomatic rate/BHP change: append a new WCONPROD/WCONINJE via append_before_end (last control in SCHEDULE wins).

Render the default 3D view of a case in ResInsight and save a PNG snapshot.

Export an LAS well log for one well using ResInsight.

Open ResInsight as an interactive GUI (relies on WSLg). Returns immediately.

Convert between formatted (F*) and unformatted ECL result files.

Compare two ECL result files within tolerances using compareECL.

Generate a restart (history -> prediction) deck via OPM's rst_deck.

Restarts base_deck from restart_case:report_step (see restart_info for available steps). Default mode "inline" produces one self-contained deck. Validate and run_flow the result for predictions.

Flatten a deck and all its INCLUDEs into a single file using opmpack.

Compute a deterministic hash of a deck using opmhash.

Run the OPM summary CLI on a case (alternative summary reader).

Detect whether the optional opm-upscaling binaries are available.

Run an opm-upscaling binary (upscale_perm, upscale_relperm, etc.) passthrough.

args is a JSON array; a plain string is also accepted and split shell-style.
