The GeoLightGas service is based on delivering information about non hydrocarbon gases in real-time. These include gases such as Helium, Hydrogen, and Carbon Dioxide which when analyzed during drilling can provide important information about bit wear, mud alteration, and corrosive reservoirs. These very light compounds provide supplementary information on the reservoir structure, the composition of its fluids and the drilling process itself.
How can I estimate the hydrocarbon potential of my discovery without waiting for fluid test results?
GeoLightGas provides a first glimpse on the non-hydrocarbon compounds that may be associated with the reservoir fluids and are measured while drilling.
Are my drilling and mud parameters correct for this type of well?
Analyzing the changes in H2 and CO2 during drilling can provide real-time indication that there could be issues with bit wear and changes to the mud properties reacting to create CO2 that affect the mud rheology.
In exploration and appraisal wells, GeoLightGas helps maximizing the fluid data gathered while drilling.
In development wells light gases can be correlated for reservoir and drilling engineering purposes.
GeoLightGas is an add-on to our advanced gas services available through G5 and G8.
Additional gases such as N2 and O2 are routinely monitored.
Non-hydrocarbon gases have been used by GEOLOG to characterize reservoir fluids and to identify drilling issues. CO2 is associated with reservoir gas and tends to disappear in reservoir oil. Helium has a similar but more complex relationship with the fluid distribution. Hydrogen has been highlighted as an indicator of bit wear and also has an affinity with oil.
