Offshore well inspections with D & C PEC

Avoiding collapsing offshore wells using Pulsed Eddy Current

D & C PEC is an application for offshore wells, using Pulsed Eddy Currents, enabling accurate corrosion measurements of the surface casing, intermediate casing and the conductor. The inspection can be executed during production of the offshore well.

With the D/C PEC data, the resulting safety factor will be calculated of the casings and connectors, which can be followed up with a failure mode feasibility analysis and additional calculations for tension table design.


Avoiding collapsing wells
Extend the life of offshore wells
Cost effective inspection without interrupting production
Cemented wells can be inspected
Better planning of production activities, workover and well-abandoning programs
Considerably reduce health, safety and environmental risks
Tool cannot be installed permanently


Accuracy + / - 5%
Areas of Application Corrosion inspection of your load carrying cases of your offshore wells, even if the well has been cemented.
ATEX certified D-PEC no ATEX. C-PEC is ATEX approved.
Capabilities All regular well configurations can be accommodated. No cleaning needed. The tool measures through marine growth. For C-PEC, with an entry via the wellhead, the pressure in the C-annulus to be controlled.
Certifications / licences Certified pulsed eddy current D/C PEC operators.
Compliance In support of well integrity codes and standards.
In-service inspection possible Inspection without interrupting the production is possible.
Inspection Lowest astronomical tight to the wellhead.
Repeatability + / - 7%
Temperature max. 100 deg. C
