comments: Broke circulation at 2466 m and pumped 104 m3 1.45 sg mud at 2000 lpm / 88-94 bar. Continued to circulate due to gas peaks at 3.35%. Reduced circulation rate to 1000 lpm / 29,8 bar, when no gas in returns. Pumped at total of 175 m3. Meanwhile circulating, inspected PRS and dragchain. Found lock nuts loose and missing.
