Coal Bed Methane Plug-in is designed for interpretation geologists and petrophysicists. It allows to characterize coal seam methane gas with the help of comprehensive workflows inside Techlog.

    Techlog 2018.1 or latest

  • Coal flag identification from standard log curves
  • Coal matrix density computation
  • Coal typing from standard log curves
  • Crossplots for coal identification, determination of coal rank, coal typing etc.
  • Hydrostatic and Langmuir pressure computation
  • Proximate Analysis to estimate volume fraction of ash, fixed carbon, moisture and volatile matter
  • Gas Content estimation using five different algorithms
  • Gas storage capacity estimation from Langmuir isotherm
  • Productivity from Spontaneous Potential data
The Coal Bed Methane plug-in covers three main functionalities namely precomputation of data, analysis and quantification of methane gas and finally post process output generation. Results can be easily calibrated with laboratory measurements and can be integrated with other answer products.
