Skid Unit

Skid Unit

The Skid unit is a service unit which consists of a cabin designed and manufactured as specified by the customer. Used as a platform for geophysical measurements in the exploration and production of oil and gas, the container can be operated fully selfcontained and remote from any supplying facilities. Air conditioning and heating systems allow operation in diverse environments.

The Skid unit has been designed to withstand temperatures ranging from -40°C – +50°C. Divided into three compartments, the container contains a winch skid, a lab designed to house the control panel for the winch and enough space for any required acquisition and interpretation equipment and the power Skid. Many modern conveniences can be incorporated for the service crew.

  • Oiler system for the cable
  • Drip pan assembled under the winch
  • Mechanically secured transport device for the logging tools
  • Black box which records each second or minute the cable speed, tension, depth, date and time

Self-contained for remote operations

  • Hydraulic winch powered by electrical or diesel power unit
  • Diesel generator for power supply
  • Compartments provided for necessary logging tools
  • Kitchen unit with fresh water tank
  • Sleepers provided

Depth computer

  • Display of depth in meter or feet
  • Display of tension in kN or lbf
  • Display speed in m/h or fpm
  • Automatic winch drive with preset speed (constant speed independent full or empty drum)
  • Automatic shutdown exceeding max. tension
  • Automatic shutdown exceeding min./max. depth
  • Automatic shutdown at relief of cable to avoid loops
  • Integrated function for calibration of depth and tension
