Expertise and state-of-the-art equipment

Petro-LS Diagraphie nterieur cabine logging

PETRO LS combines the technical expertise of a major player with the agility of a small business. Our fully equipped logging trucks allow us to offer a complete range of services suited to every phase in the life of your wells.

We have chosen high-end equipment to meet the most complex and demanding challenges.

We are equipped with high-temperature (260°C) mono- and hepta-conductor cables, allowing optimal logging speeds. Our fiber optic cable is rated to 150°C.

Reliability and performance in harsh conditions

Operations are carried out with our own units and our own cables, giving us full control of the intervention for reliable, high-performance execution.

All our tools are designed to withstand harsh conditions, whether high temperature (177°C), high pressure of 135 MPa (20,000 PSI) or corrosive environments.

We also operate in deviated and horizontal wells, where we can use dedicated conveyance methods to bring the tools to the bottom of the well.

Our open hole logging services provide an accurate evaluation of the formations drilled, delivering data that is essential for reservoir characterization, petrophysical property determination and geological modeling.


A non-exhaustive list of combinable tools, allowing acquisition times to be optimized, that we can offer you:

  • TCMRT (Tension, Compression, Mud Resistivity, Temperature)
  • Gamma-Ray (GR)
  • Borehole Compensated Sonic (BHC)
  • Multi-Arm Caliper
  • Acoustic Borehole Imager (ABI)
  • Spectral Gamma-Ray
  • Dual Induction
  • Array Induction

  • Production Logging Tool (PLT)
  • Fiber optic measurements (DAS/DTS/DSS/VSP/Camera)

Cased hole logging provides a detailed analysis delivering essential information on well design, well integrity, cement evaluation and productivity/injectivity.

Examples of services:

  • TCMRT (Tension, Compression, Mud Resistivity, Temperature)
  • Casing Collar Locator (CCL)
  • Gamma-Ray (GR)
  • Cement Bond Log (CBL & Radial CBL - VDL)
  • Multi Finger Caliper (MFC)
  • Acoustic Borehole Imager (ABI)
  • Ultrasonic Tool (Casing inspection & Cementation)
  • Production Logging Tool (PLT)
  • Deviation Survey
  • Orientation (Azimuth)
  • Casing Inspection Tool (Magnetic)
  • Fiber optic measurements (DAS/DTS/DSS/VSP/Camera)

Performance and Innovation

Many of our tools are combinable, making it possible to run a wide range of measurements in a single run and so optimize intervention time. Our telemetry systems ensure fast transmission of downhole data.

Thanks to solid, long-standing partnerships, we cover the full range of logging requirements.

For any specific request not listed above, we are ready to develop new partnerships in order to meet it effectively.
