Capture trains, compression and injection wells proven ahead of first CO2
Commissioning software for carbon capture and storage where capture trains, compression trains and injection wells each carry their own test regime that has to close out before the first tonne of CO2 moves.
A CCS project spans three distinct scopes that are rarely run by the same contractor: a capture train stripping CO2 from flue gas, a compression and pipeline system moving it to a storage site, and injection wells putting it underground under a monitoring, reporting and verification (MRV) plan regulators will audit for decades. Deskely holds all three scopes in one register with the pressure testing, compression commissioning and injection well gates built in.

The problem
Capture, compression and injection are three different projects run by three different contractors, and a regulator will ask for one continuous evidence trail across all of them.
The capture train, the compression and pipeline system, and the injection wells are typically engineered, procured and commissioned by separate contractors on separate schedules, each with its own test regime and its own definition of mechanical completion.
When capture train test data, pipeline hydrotest records and injection well integrity tests sit in three separate contractor closeout packages, nobody can assemble the single evidence trail an MRV plan and its regulator will expect before CO2 is allowed underground.
Deskely holds capture, compression and injection assets in one register with a shared readiness model, so first-injection readiness reflects evidence across the whole chain rather than three contractors each declaring their own scope complete.
Setting up the register
Capture columns, compressors, pipeline and wells are tagged assets spanning three commissioning scopes.
P&IDs for the capture train, pipeline route drawings and injection well schematics are parsed into a reviewed register, so every absorber column, compressor, pipeline section and well carries its design data and test requirement from day one.
Capture train commissioning templates, CO2 compressor acceptance tests and pipeline hydrotest procedures are templated once per equipment type, respecting the different contractors and standards each scope is built to.
Injection well integrity testing — casing pressure tests, cement bond logs and mechanical integrity tests — is held as its own record set tied to the MRV plan's monitoring requirements, distinct from surface facility commissioning.
Execution
Capture, compression and well testing are gated independently, then rolled up into one first-injection readiness view.
Capture train commissioning proves absorber and stripper performance against design CO2 capture rate, while compressor trains are tested through their full pressure ratio range with vibration and surge protection verified before pipeline tie-in.
Pipeline sections undergo hydrotesting and integrity verification against the design code, with records captured per section so a hydrotest failure on one segment does not obscure the readiness of the rest of the route.
Injection wells are proven through mechanical integrity testing and casing pressure tests, with findings logged against the specific well, so first-injection readiness is reported well by well rather than assumed once drilling is reported complete.
First injection and handover to operations
First injection is authorised from a chain of signed evidence, spanning capture, compression and the well, because that is what the MRV plan and the regulator will expect to audit.
Capture train performance data, compressor commissioning reports, pipeline hydrotest certificates and well integrity test results all export from the same register, so the first-injection evidence package satisfies the MRV plan in one submission.
The handover pack for the operations and monitoring team includes as-built process data, pipeline integrity baselines and well test data keyed to the register, giving the long-term monitoring programme the same starting evidence used to authorise injection.
Every signature carries a name, role and timestamp, which is what the regulator, the storage site operator and the asset owner's insurer will ask for before CO2 injection is authorised rather than trialled.
The dossier
First injection is a baseline, not an endpoint, for a monitoring programme regulators expect for decades.
The monitoring, reporting and verification plan's instruments have to be calibrated and baselined before first injection, because every later reading is judged against that baseline. The dossier keeps capture-side purity evidence and well integrity records tied to their own tags and schedules.
CO2 purity certificate
captured CO2 meets the pipeline or injection specification for moisture and contaminant content
on each batch prior to transport or injection
Capture unit commissioning report
the amine or equivalent capture process removes CO2 at the design capture rate
at first sustained operation of the capture unit
Injection well integrity test record
casing and wellhead integrity meet the design pressure rating before injection begins
before first injection into the well
MRV instrument calibration and baseline record
downhole pressure, seismic and groundwater monitoring instruments are calibrated with a recorded baseline reading
before first injection, referenced for the life of the MRV plan
Mechanical integrity re-test record
the injection well continues to meet its integrity criteria on the schedule the MRV plan requires
on the periodic interval set by the regulator
Injection rate and pressure compliance record
actual injection operations stayed within the permitted rate and pressure envelope
continuously through injection operations, reported to the regulator
How it runs
From three contractor scopes to one first-injection readiness view.
CCS programmes reward a register that spans capture, compression and injection from the outset, because the MRV plan will ask for a continuous evidence trail across all three, not three separate closeout binders.
- 01
Model the full chain
Capture columns, compressors, pipeline sections and injection wells modelled as assets across all three commissioning scopes.
- 02
Parse P&IDs and well schematics
Capture train P&IDs, pipeline drawings and injection well schematics drafted into one reviewed register with design data attached.
- 03
Template each scope's tests
Capture train, compressor acceptance, pipeline hydrotest and well integrity tests defined once per equipment type, instantiated across every asset.
- 04
Gate first injection on the full chain
First-injection readiness reported only once capture, compression and well records are all signed, satisfying the MRV plan in one export.
