Прошу помочь перевести "written" из документа Enhanced Steam Management of SAGD Wells Using Reliable and Permanent Real-Time FBG-Based Thermal Monitoring:

Visualization of Field Data During SAGD Production Period
In this example we see the field data from an injector well that the producer has been operating for over a year, but the steam chamber is not yet fully developed or matured.
The monitoring system was designed with 40 LxATS sensors and 1 pressure/temperature gauge at the toe.
These sensors were *written into* the core of the fiber using the FBG writing system and providing 20-meter spatial resolution along the horizontal.

Спасибо.
