The document discusses the steps involved in well completion, including: - Cleaning out the wellbore by running a bit and scraper to remove cement and cuttings. - Circulating the well from bottom to top with completion fluid to displace drilling mud. - Measuring the clarity of the returning fluid using an NTU measurement to ensure it is below 25. - The goal is to clean the wellbore before running the completion string.
