Most commonly used in well logging, perforating and well surveillance activities; real time data is obtained through the electric cable and provides accuracy of depth control and well information. Normally performed under 'live' well conditions.

Equipment:

The equipment required to conduct electric line operations consist of:

  • Mono conductor cable which can be supplied from 7/32" - 7/16"
  • Winch unit capable of holding up to 25,000ft of wire
  • Diesel or Electric Powerpack
  • Well Control Panel
  • Grease injection pump unit
  • Pressure control equipment comprising Lubricator / Grease injection head / BOPS /Riser
  • Logging /Data centre for storing / analysing data during the operation (this unit may form part of the winch unit)
  • Tool house holding logging tools and equipment


Applications:

Electric line can be used for many applications but predominantly well logging activities such as:
  • Cased Hole Logging - Production logging to determine zonal contributions, water or gas influxes, permeability and porosity measurement
  • Open Hole Logging - Reservoir monitoring, Resistivity measurement, formation testing
  • Perforating - casing and tubing perforation operations
  • Explosive Devices - Setting packers, plugs and straddles
  • Drilling Support Services - Explosive back off operations to free stuck drillpipe
