Mud Logging examines and analyzes geological information contained in formation cuttings and drilling mud, to determine if oil and gas are encountered during well drilling. Mud Logging also provides critical safety functions such as determining pore pressure, kick control and ambient gas monitoring. Mud Logging is used while drilling most exploratory and many development wells, both onshore and offshore.

Mud Logging services have evolved to become the information center for the well and include the electronic monitoring of drilling parameters. These parameters include weight on bit, torque, penetration rate, mud levels, pump speed and third party service provider data.


Basic services use a cost effective Mud Logging unit that provides gas detection to identify potentially productive pay zones and enhance drilling safety. The system is configurable for hydrogen sulfide H2S monitoring. The units are equipped with the alarms to alert the user if gas increases or equipment problems occur and works in conjunction with the data logging and drilling penetration rates.

Our Task


    • Advanced drilling monitoring systems capable of the gas detection, electronic monitoring and database recording for a full range of drilling parameters
    • Experienced crews and additional tools to monitor and analyze both the geology of the subsurface information and the drilling parameters.
    • Various combinations of services and crew sizes depending on the customer’s requirements and well complexity.
    • A portable laboratory (Mud Logging unit) that houses the hardware and software analysis conducted at well-site during the drilling process and samples are returned to the operator after analysis.


The advantages of MAPSA-Kish Mud Logging services are as follows:

      • Sensors and data analysis system : French – EU,
      • Gas analysis system : American,
      • Supporting & training workshops in Kish Island.
