AccessFrac ServiceTraditionally use drillable bridge plugs to isolate clusters
• Physical barrier• Means to deliver perforating guns• Highly reliable• Drillable
What other mechanism can we use to isolate clusters?
Improvement Opportunities / Risk Mitigation• Reduce time – installation• Reduce time – removal• Reduce risk – premature set or perforating• Reduce cost – displacement fluids
Biovert ® NWB Self-Degrading Diverting Agent

Pump perforating gun and frac plug on depth Set the frac plug Correlate perforating gun and perforate Pull out of the hole Time requirements 3-5 hours Repeat the process 15 – 30 times Equipment standby time between 2 and 7 days At conclusion the plugs have to be drilled out using a rig

Group 2 or 3 perforation clusters Pump perforating guns and frac plug on depth Pump frac treatments followed by diverters Repeat as needed to cover lateral Savings – Time 6-10 hours (perf & plug ops) per group Savings – Time 1-4 days (equipment stand-by ) per well Savings – Safety: reduce perforating exposure Reduce - Risk of bridge plug setting prematurely Savings – Cost of 66% of bridge plugs Savings – Time reduce drill out ops by 66% To clean well out:
– Diverter self degrades– Plugs drilled out using rig
Savings – Reduced displacement fluid by 66% Savings – Time (faster) for fluid flow back
