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.

3-WELL CONCURRENT FRAC. WAITED ON OTHER JOBS TO BEGIN. PRE-ISIP = 2874 PSI, 

5-MIN = 1958 PSI. THE TREATMENT EXHIBITED A NEGATIVE TREND (NOLTE= -0.26) UNTIL

THE RAMP. THE TREND THEN TURNED POSITIVE THROUGHOUT THE REMAINDER OF 

THE TREATMENT. POST-ISIP = 3299 PSI, 5-MIN = 2910 PSI. 18 BBLS DOWN ANNULUS.
