2. Presentation agenda
• Tracer technology overview
• Pad design optimization utilizing molecular tracers
• Well Spacing
• Completion Design
• Stage by Stage Production Confirmation
• Magnitude of Communication with Offsets
• What can we learn?
• Data Analytics
• Case Study
3. Today's tracer programs
blur lines between
conventional and
unconventional projects as
technology applied over
years of experience and
knowledge gained are
used together to optimize
production
Tracers used for reservoir characterization as well as
production and field development optimization
5. So, what can we learn?
• Are our wells spaced to minimize communication?
• Is well spacing maximizing our footprint?
• Which zones are performing well? Which aren’t?
• Did we communicate with offset wells?
• What is the magnitude of offset communication?
18. Case study overview
• Operator was drilling and completing a 4-stage vertical well.
• All 4 stages were traced with unique molecular oil and water tracers.
• Operator was trying to determine:
• All stages were contributing
• Which zones yielded profitable oil production
• Determining completions “pay zone” by overlaying geological and completions
data with the analytical tracer results.
• Is mechanical intervention required to achieve optimal performance?
21. Data analytics take-aways
• Stages 2-4 Accounted for 60% of water production and 99% of oil
production.
• Stage 1 accounts for 40% of water production and only 1% of oil
production.
• Operator decided to plug the first stage and only produce out of stages 2-
4.
• Successful isolation of the first stage (bottom stage) yields:
• 40% reduction of produced water, lowering disposal costs.
• No measurable decrease in oil production.
• Optimization of future drilling plans.
