Well site operations

Our teams of mud-loggers, well-site geologists, engineers and geophysicists provide the onsite services in Oil & Gas and geothermy sectors.

Our internationally mobile multidisciplinary team has a strong expreriance in work for different environments (onshore/offshore etc.).




Our technical assistance team are expert in all types of drilling activity:

  • Vertical, deviated, horizontal wells.
  • Exploration drilling programmes onshore, offshore and shallow transition zone environments, in many parts of the world

We a good expertise in the more specific drilling operaions, such as those in ultra-deep water, high pressure and high temperature environments, H2S and unconventional resources.


Our wellsite geologists provide the following service operations:

  • Geological data follow-up and monitoring while drilling (drilling parameters, mudlogging, description of penetrated formations, hydrocarbon shows, coring,...)
  • Data acquisition monitoring and quality control  (wireline, MWD, LWD)
  • Daily reporting
  • Pre-interpretation (correlation)
  • End of survey reports preparation
  • Final well report
