Abstract
A well completion arrangement and method is for removing at least a portion of a line running in an annulus between a tubing and a casing in a well. The arrangement comprises at least two clamping means spaced apart in the longitudinal direction of the tubing and fixed thereto, the clamping means being configured for fixing the line with respect to tubing, a splitting means for releasing the line from the interval defined by at least an upper clamping means and a lower clamping means of the at least two clamping means, a line manipulator apparatus for activating said release of the line, and a line retrieval apparatus for displacing into the tubing the portion of the line from said interval, thereby removing the line from the annulus.

A well completion arrangement for removing at least a portion of a line running in an annulus between a tubing and a casing in a well, the arrangement comprising:
- at least two clamping means spaced apart in the longitudinal direction of the tubing and fixed thereto, the clamping means being configured for fixing the line with respect to tubing;
- splitting means for releasing the line from the interval defined by at least an upper clamping means and a lower clamping means of the at least two clamping means;
- a line manipulator apparatus, for activating said release of the line;
- a line retrieval apparatus for displacing into the tubing the portion of the line from said interval, thereby removing the line from the annulus.
A method of preparing a well for abandonment, the method comprising:
- incorporating at least two spaced apart clamping means in a tubing during completion of the well, the clamping means being provided with a holding means for fixing a line with respect to the clamping means, the line running in an annulus between the tubing and a casing;
- providing splitting means for releasing the line at least at an upper clamping means and at a lower clamping means of the at least two clamping means,
- providing an apparatus for inducing said release of the line;
- and
- providing an apparatus for displacing into the tubing the portion of the line from the interval defined by at least the upper clamping means and at the lower clamping means of the at least two clamping means.
