## (CODELL RC): PRE-FRAC: REVERSE STEP RATE: 21 PERFS OPEN, NWB 238 PSI, PERF FRIC 410 PSI. LOST BLENDER TUB DURING PAD, SHUT DOWN FIX SUCTION PUMP. FRAC COMMUNICATING WITH NIO C BENCH TO BACKSIDE, BROUGHT PRESSURE UP TO OFFSET (CONTINUOUSLY PUMPED ON BACKSIDE TO OVERCOME PRESSURE). WH FLANGE STARTED LEAKING, FLUSHED WELL AND TIGHTENED. RESUMED JOB WITH 2# STAGE, STAGED TO 3# EARLY TO CONSERVE WATER. MOVER BELT STOPPED DURING 3# STAGE, SANDED BELT OFF. DROPPED RATE TO TRY TO CLEAN OFF, ENDED UP FLUSHING WELL TO FIX. CAME BACK ON WITH 3# SAND, STAGED TO 4# EARLY TO CONSERVE WATER. INCREASED DENSITY DURING 4# STAGE. LEFT 2K IN MOVER.
