Mud Gas Analysis
Mud Gas Isotopes
GEOCHEMICAL CHARACTERIZATIONÂ
GeoMark Research’s established Mud Gas Isotope laboratory has been serving the industry for over 15 years, providing timely and trusted gas analysis data from exploration and production wells around the world. Our data provides insights to the following:
-
Gas Compositions: Cost effective screening technique to quickly identify hydrocarbon bearing zones
-
Gas Classification (Biogenic vs. Thermogenic): Helps determine the source of gas encountered within a well
-
Maturity and Mixing: Evaluates delivery of gas source maturity and relative mixing between thermogenic and bacterial (insights to migration)
-
Wetness: Identifies dry gas, condensate, or oil throughout the well
-
Connectivity: Assesses if reservoirs are connected or sourced from the same source
-
Helium: Exploration of alternative natural resources
The figures below present a selection of data outputs and interpretations that can be made from Mud Gas Isotope Analysis. Stable gas isotopic data (methane, ethane, propane and higher molecules) have traditionally been used as geochemical source and maturity markers and to indicate the relative concentrations of biogenic and thermogenic components in reservoir fluids. Collected over multiple wells, this data can be used to evaluate continuity between different zones in single and multiple wells; connected reservoirs should have similar isotopic values.
