GC composition analysis software for PVT and gas labs

Turn GC exports into engineering-ready compositions and reports.

ChemStation CSV · Chromperfect ZED for Liquid GC · xlsx report export

GC Reader turns GC export files into reviewed gas, liquid, and recombined wellstream composition reports. It handles Agilent ChemStation CSV imports, Chromperfect ZED files for black-oil Liquid GC workflows, FID/TCD detector merge, air correction, ISD normalization, component aliases and reporting groups, GOR recombination, and xlsx report export without forcing lab staff into fragile copy-paste spreadsheets.

The lab problem

GC systems give you chromatogram exports. Engineering teams need defensible composition reports.

Raw GC exports are rarely the final deliverable. PVT labs still have to merge detector channels, correct air contamination, map component names, normalize results, recombine gas and liquid analyses, and package a report that another engineer can review. GC Reader is built for that handoff, including ChemStation CSV files and Chromperfect ZED files used in black-oil Liquid GC work.

Reduce manual spreadsheet risk

Replace repeated copy-paste, tie-factor calculations, and component-name cleanup with a controlled workbook workflow.

Keep chromatographer control

Methods, tie components, ISD parameters, aliases, reporting groups, and plus-fraction assumptions remain visible and adjustable.

Standardize recurring reports

Use the same parsing and normalization rules across repeated PVT studies, gas QC runs, and engineering handoffs.

Workflow

From GC export to composition report.

GC Reader is a standalone lab product for turning GC data into usable composition deliverables. ChemStation CSV files feed the existing gas and liquid workflows, while Chromperfect ZED files can be loaded into the Liquid GC workflow for black-oil GC analysis. Cleaned compositions can then be exported as an xlsx report workbook or used in downstream EOS, dew-point, PVT, or reporting workflows.

GC Reader workflow from GC export to engineering-ready composition report ChemStation CSV exports feed gas and liquid inputs. Chromperfect ZED files feed the black-oil Liquid GC workflow. GC Reader combines gas and liquid results through GOR recombination and exports xlsx reports.

Use cases

Where GC Reader fits.

PVT lab reporting

Produce consistent gas, liquid, and recombined wellstream composition tables for reservoir-fluid studies, separator samples, and EOS handoff packages.

Gas lab quality control

Standardize detector merge, air correction, normalization, component alias rules, and reporting-component grouping across recurring gas chromatography methods.

Engineering composition handoff

Convert lab exports into mol% and wt% tables that reservoir, process, and flow-assurance engineers can use without reformatting.

Recurring report automation

Reduce repeated manual workbook preparation when the same GC method, component list, or report pack is produced every week or month.

Want to know whether your export can be parsed?

Send a representative ChemStation CSV or Chromperfect ZED export and describe the report you need. If your lab uses another GC export layout, we can review a sample file during qualification. We will confirm the parsing path, detector merge assumptions, and whether GC Reader is a fit for your workflow.

The interface is organized around the same lab workflow: gas GC merge, liquid GC normalization, Chromperfect ZED import for black-oil Liquid GC work, GOR recombination, xlsx report export, and the editable component library.

Capabilities

Core modules.

Gas composition analysis

Reads FID and TCD detector exports, merges them through a configurable tie component, applies optional air correction, and outputs normalized gas composition tables.

Liquid composition analysis

Supports internal-standard liquid GC workflows with editable ISD component, sample weight, purity, and heavy-fraction assumptions up to C30+.

Chromperfect ZED import

Reads Chromperfect ZED files into the Liquid GC workflow for black-oil GC analysis. The user selects the file type during load, then reviews and processes the result through the same Liquid GC controls used for CSV data.

GOR recombination

Combines gas-phase and liquid-phase compositions using a user-supplied gas-oil ratio to produce a single wellstream composition for engineering use.

XLSX report export

Exports a report workbook with summary, gas composition, liquid composition, recombined composition, Cn+ properties, processing log, processed input data, and metadata sheets.

Component library and aliases

Maintains a configurable petroleum component library with aliases for lab-specific names, method-specific labels, and plus-fraction conventions. Naming errors and non-standard names are common in GC exports, including spelling mistakes and shorthand labels, so GC Reader flags unknown imported names and lets the user add an alias before rerunning the import cleanly.

Alias-based component grouping

Alias rules can also roll selected imported names into a required reporting component. For example, iC5, nC5, neoC5, and cycloC5 can be grouped into a single C5 reporting line when that is the lab or client reporting basis.

Technical specifications

Input formatsAgilent ChemStation CSV exports for existing GC workflows; Chromperfect ZED files for black-oil Liquid GC workflows. Other GC export layouts can be reviewed during sample-file qualification.
Analysis workflowsGas composition, liquid composition with ISD normalization, Chromperfect ZED import for Liquid GC, and gas/liquid recombination by GOR.

OutputsNormalized mole percent and weight percent composition tables plus xlsx report workbooks for reporting, review, and engineering handoff.
PlatformProtected Windows desktop application powered by Microsoft Excel; supported Excel versions are confirmed during workflow qualification.
CustomizationThe predefined 77-component library can be edited and extended by users. Component aliases, alias-based grouping rules, molecular weights, ISD settings, report layout, and lab-specific naming conventions can be configured by project.
Downstream calculation note: when a cleaned composition is needed for hydrocarbon dew point, phase envelope, or EOS analysis, it can be handed off to DPCloud or other engineering tools. GC Reader remains the primary product for the GC export-to-composition workflow.

Sample-file review

See GC Reader on your own export.

The fastest way to qualify a workflow is to review representative input files and the report format your lab needs to deliver.

Next step

Send us one representative ChemStation CSV or Chromperfect ZED export and the xlsx report format you want to produce. A sample file is the fastest way to confirm parser fit, component naming, and detector merge assumptions.

Trial files are prepared manually for your workflow, so the 30-day trial can use representative GC exports instead of a generic demo dataset.
