Surface Logging Systems

Identify pay zones, track lithology, and enhance safety while drilling 

Leveraging 50 years of experience in surface logging, our services are your first line of defense against unplanned events. Our comprehensive technologies—ranging from conventional mud logging to advanced wellsite geochemical analysis—maximize drilling efficiency and provide real-time formation evaluation data, including lithology, gas analysis, hydrocarbon content, porosity, and more.

Mud-Logging Services

Analyze rock cuttings and hydrocarbons carried to the surface

Our surface logging service mobilizes experienced teams that help you to determine the presence of oil and gas, reduce reservoir uncertainty, mitigate hazards, and optimize drilling efficiency.
