Our Services

We offer services and studies based on natural gas geochemistry and geology for natural gas exploration, production, storage and related environmental implications.

We perform field surveys, offer interpretative services, training and research reports for:


  • Surface exploration
  • Gas seepage detection with evaluation of gas origin (isotope-molecular analysis)
  • Gas isotope analyses in exploration wells
  • Gas isotope analyses in production wells
  • Mudgas isotope analyses while drilling
  • Monitoring gas dynamics in gas storage facilities
  • Gas in soil and groundwater (buried pipelines and wells, landfills, seewage facilities)
  • Surface Casing Gas

Reports and Data for Sale

Regional studies on gas formation and occurrence and gas isotope data (e.g., Norwegian Sea, Barents Sea, West Greenland)

Training on gas geochemistry and gas seepage detection for universities, research centers and oil industry


GAS SEEPAGE, a fundamental and widespread process in gas-oil fields

We detect various manifestations of seepage
(macro and micro-seepage), through gas analyses in soil and
groundwater, and can:

  • provide maps and geospatial analyses
  • measure the amount of gas ascending from the reservoir
  • assess gas origin (microbial, thermogenic, dry or associated to oil)
  • assess secondary alterations (oxidation, molecular fractionation)
  • identify biodegradation (undetectable by geophysical methods)
  • assess the presence of undesiderable gases (CO2, H2S, N2)
  • define reservoir compartmentalization
  • estimate source rock maturity

Exploration and Production

Gas Isotope Analysis in exploration and production wells provides fundamental information on the petroleum system

  • Microbial vs thermogenic gas origin
  • Maturity and depth of gas source
  • Gas potential
  • Timing of gas formation
  • Distribution of source rocks and their maturity
  • Distribution of oil vs. gas areas
  • Depth of source rock
  • Long distance migration


Monitoring Gas Dynamics in Gas Storage Facilities

Gas injection and withdrawal of pipeline gas

Quantification of displacement of native reservoir gas
Monitoring of injection and withdrawal


Gas in soil and groundwater

The same surface techniques used for gas exploration can be applied to environmental investigations, such as:

  • Pipeline leaks
  • Monitoring of Landfill sites
  • Refuge repositories Sewage plants
  • Groundwater pollution
  • Leaks from horizontal wells
  • Leaks from Storage Facilities

Surface Casing Gas (SCG)

Abandoned wells as sources for methane pollution

Abandoned wells can release methane through casing leaks
Surface analyses of soil gas can identify SCG

Fugitive Methane from Gas Storage Facilities

Identification of potential methane sources resulting from pressurisation and de-pressurisation of the storage reservoir during gas injection and withdrawal

  • Migration of methane into the formation waters
  • Diffusion of storage methane through the ‘impermeable’ caprock
  • Accumulation of methane in the upper aquifer
  • Potential groundwater pollution
  • Leakage of methane along development wells
