Abstract
An arrangement is for forming a freeze plug in a tubing. The arrangement includes a first and a second displacement element adapted to be displaced within the tubing with a medium between them that is adapted to form the freeze plug. The first and the second displacement elements include, at least at a respective end portion facing the medium between them, a sensor arrangement for measuring at least one of a pressure and a temperature.
Claims10
An arrangement for forming a freeze plug in a tubing, the arrangement comprising:
- an elongated first displacement element and an elongated second displacement element adapted to be displaced within the tubing with a medium between them that is adapted to form said freeze plug,
- wherein the first displacement element and the second displacement element comprise, at least at a respective end portion facing the medium between them, a sensor arrangement for measuring at least one of a pressure and a temperature.
A method for forming a freeze plug in a tubing, the method comprising:
- displacing an elongated first displacement element and an elongated second displacement element within the tubing with a medium between them that is adapted to form said freeze plug,
- positioning the first displacement element and the second displacement element at respective parts of the tubing in between which the freeze plug is to be formed,
- freezing the tubing between the first displacement element and second displacement element, thereby forming the freeze plug,
- measuring at least one of the pressure and temperature on respective end portions of the displacement elements facing the medium between them, and
- determining if the freeze plug has a sufficient quality on basis of a difference in at least one of the pressure and the temperature between the displacement elements.
