Scraper run before running liners

Hi folks

At a recent DWOP, we noticed that the team are planning to run dedicated scraper runs before running liners.  This is due to "problems" in the past with liner hangers/packers.

We have not come across this practice before and would like to hear your thoughts (and, in particular, experience).

• Who (out there) is making dedicated scraper runs? (and WHY)
• Who is not and what problems have you ever had?
• What other options are there (such as RFID-activated or ball/pressure activated scrapers) run with the drilling BHA? And what experience/best practice/ lessons from them?

Many thanks


Dave
