The Production Logging Tool provides a complete solution for acquiring, recording, and processing surface and downhole well production data.

This easy to operate, portable logging system is offered in a 1 3/8” and 1” diameter. Surface Read Out (SRO) version with a memory option available for the 1 3/8” diameter tool. The high-speed instrument bus and smart sensor-based tools allow the operator to interchange and configure the tool string to suit well conditions.

The following sensor modules are available:

  • Accelerometer
  • Gamma Ray
  • Casing Collar Locator
  • Quartz and Sapphire Pressure
  • Fast response Temperature
  • Fluid Dielectric (Capacitance)
  • Acoustic Density
  • Fullbore Folding Flowmeter
  • Caged Flowmeter
  • Inline Flowmeter
  • 4 Arm Roller Centralizer
  • X-Y caliper

How It Works

The Telemetry tool's bidirectional, high-speed, digital communications bus allows the operator to log, record and view downhole data from all sensors inreal time over conventional, single conductor wireline.

A unique feature of the bidirectional communication link is that it allows the operator to query each smart sensor at any time, for key configuration parameters such as its serial number and position in the tool string.

This feature combined with the database architecture greatly automates the setup and calibration procedures prior to each survey.
