~ Cemented without returns

- Did not see Weatherford bottom plug release or land

- Top plug landed as expected

@ RIH with 14.75" x 16.5" Drilling BHA

-· Increased MW (11.5 ppg)

- Lesson Learned - DO w/ previous HS MW for LOT

- Drilled ratty shoe track

- Loss returns 3' above float equipment (channel)

G Pumped 160 bbls LCM pill (losses reduced 90 bph- 60 bph)

- Closed annular while cut mud back in pits and riser

~ Cut MW to 11.3 ppg (losses reduced to 24 bph) @ With annular closed cut MW in kill to 11.1 ppg (well static)

~ Cut MW in riser to 11.1 ppg and opened annular (losses static) ~~; RIH and cleaned out to -11 1619' TVD (bridge)
