Improved Well Log Achieved by Placing Magnet in front of Logging Tool
A Magnetic Drift with brush was run below the logging tool, in order to clean the well for magnetic swarf.
Location: Offshore, Norway

Introduction


Understanding well integrity is important to make critical decisions during drilling and completion operations. By examining the bond between the casing and the cement pumped into the wellbore annulus, we are able to determine if remedial work is required before completing the well. Such information can be obtained by running cement bond logging tools. In this particular case Baker Hughes was going to run their Integrity eXplorer™, a cement bond logging tool, to evaluate an injector well.

Challenge


The Baker Hughes Integrity eXplorer™ logging tool uses patented electromagnetic-acoustic transducers capable of measuring the cement bond in any wellbore fluid environment. However, previous experiences with the tool have revealed that it collects a lot of magnetic swarf. The magnetic swarf has also influenced the set-up of the tool, which makes the operator use more time than necessary on this operation.

Solution


Baker Hughes was looking for a magnet to be installed beneath the logging tool to collect the swarf and provide a clean casing for the logging tool. Innovar recommended using an MD 5500 magnet, which also has a brush attached in front of the magnet for cleaning purposes. 


Benefit


By applying the MD 5500 magnet in front of the logging tool, the Innovar magnet was able to secure most of the magnetic swarf, keeping the swarf attached to the Integrity eXplorer™ to a bare minimum. This resultet in reduced time on tool set up and therefore, reduced rig time.
 


 

“It really helped clean up the well so that the metal debris sticking to our tool was kept to a minimum. For that reason, it is highly likely that we will use it again for future operations.”

Case Study

Challenge:

  • Magnetic swarf interferes with the logging tool
  • Complicates the operation
 

Solution:

  • Installed a MD 5500 magnet which includes a brush beneath the logging tool
 

Benefit:

  • The MD 5500 recovered most of the magnetic swarf downhole
  • Prevented interference with the logging tool
  • Reduced rig time
