Challenge: Determine the optimal pump
schedule and diversion strategy to maximize the zonal coverage achieved from
stimulating the horizontal openhole section of a water injector well
Solution:
- Use ACTive Q real-time flow measurement service to obtain an accurate
prestimulation injection profile
- Adjust the stimulation strategy to optimize the coverage and
effectiveness of the treatment fluid
- Acquire a postinjection flow profile with the ACTive DFLO CT
real-time flow measurement tool at the end of the stimulation run to confirm
treatment effectiveness
Results:
- Reduced the wellhead injection pressure from 1,000 psi prestimulation
to zero psi poststimulation, with a constant injection rate of 8 bbl/min [1.27
m3/min]
- Improved injectivity after acid stimulation and achieved a more
uniform injection over the 2,400 ft [731.5 m] of the horizontal openhole
section
- Performed preprofiling, stimulation, and postprofiling in a single
run, which minimized costs, enabled fast decision making, and improved
operational turnaround time
