The study on groundwater data has taken almost two years to complete and includes information on more than 10,000 registered water bores.
Spokesman Tor McCaul says it will help to improve understanding of groundwater systems and should result in better future management.
"There wasn't any new data added to this study right now," he said.
"It's a summary of everything that is existing.
"Part of what it does is to try and identify which areas of the basin need particular monitoring."
The Gasfields Commission is visiting Longreach this week to hear from companies, landholders and councils on CSG exploration.
