Start with the job you need to do
The suite is not one product with ten names. Each tool answers a different question, and several are designed to be used together.
Check the rows first
haql-qc finds bad records. haql-closeout checks whether the month ties together.
Find what the summary hides
haql-revenue reconciles purchaser statements. haql-dataroom cross-checks a seller's package.
Make the evidence checkable
haql-45q, haql-emission and haql-rrc check credits, emissions and filings.
Look behind the forecast
haql-engine explains the reservoir engine in plain language, with evidence and limits.
Use the free foundations
haql-units and haql-coords are MIT-licensed libraries for conversions and wellbore geometry.
Read the claims and limits
Every guide separates what a tool does from what it does not do. That is deliberate.
All product guides
These are the public guides for the products listed on the Haql Labs site. Each one follows the same structure so the claims are comparable.
haql-qc
Row-level checks for missing, negative, contradictory and impossible production records.
Read the guide → Production data qualityhaql-closeout
Period-level reconciliation that finds the wells and days blocking a clean month-end close.
Read the guide → Revenue and settlementshaql-revenue
Reconcile production against purchaser statements and rank every exception by dollar impact.
Read the guide → Acquisition due diligencehaql-dataroom
Cross-check seller production, wells, RRC, revenue, severance, reserves and LAS headers before a bid.
Read the guide → Compliance and creditshaql-45q
Reconcile capture, injection and monitoring records into a 45Q credit schedule and evidence pack.
Read the guide → Compliance and creditshaql-emission
Reconcile a GHG inventory to activity data and show the EU ETS allowance position.
Read the guide → Regulatory filingshaql-rrc
Pre-filing audit for Texas RRC Form PR operator numbers, disposition codes, districts and deadlines.
Read the guide → Reservoir engineeringhaql-engine
A plain-language guide to the reservoir simulator: what a forecast means, how uncertainty is handled, and what the evidence proves.
Read the guide → Free engineering library · MIThaql-units
Conversions with explicit definitions, time bases, citations and dimension checks.
Read the guide → Free engineering library · MIThaql-coords
Minimum-curvature well paths, UTM conversion and deterministic survey certificates.
Read the guide →How the tools fit together
The products are deliberately separate. Data quality, period close, revenue and compliance are different questions; mixing them into one opaque system would hide the evidence.
haql-qc clears missing, negative and contradictory records.
haql-closeout checks that the month reconciles.
haql-revenue reconciles statements and ranks exceptions by dollars.
haql-45q, haql-emission and haql-rrc prepare the evidence.
For an acquisition, haql-dataroom cross-checks the seller's package. For a reservoir forecast, haql-engine explains how the model and its uncertainty are checked.
Common promises
These are the design choices shared across the paid suite. They are also the questions to ask before trusting any output.
Files in, reports out
The paid tools run offline. The data stays on your machine; there is no portal upload, database connection or telemetry.
Same input, same findings
A rule has a stable identifier. The same bytes should produce the same report, which makes a later review possible.
Every finding has a source
Reports point to the rule, source row and input fingerprint. Optional signed attestations make later edits detectable.
Advisory by design: a finding is a question with evidence, not an automatic legal, financial or engineering conclusion. The judgement remains with the professional reviewing it.
Free engineering libraries
Two foundations of the suite are free and MIT-licensed. They are deliberately small, so they can be inspected and reused without a commercial relationship.
How to read a guide
Every product guide answers the same questions in the same order: what it does, why it matters, what goes in, what comes out, what it checks, what it does not do, and how to try it. If a claim is not supported, it should not be in the guide.
For the reservoir engine specifically, the public engine guide also explains the evidence and the current scientific limits. The technical reference is there for engineers who want the equations and file map.
