Common Question
What extra work is needed for single-barrier hydraulic fracturing?
Archive Findings
Directive 083 requires single-barrier designs to document casing load capacity, safety factors, adjusted maximum pressure, cementing practice, casing and cement integrity, and post-frac checks.
The FAQ adds that monobore designs need more diligence because they lack a second monitored barrier.

Engineering Insight
Prepare a concise integrity package before pumping. Include casing design, dogleg-adjusted burst/collapse, cementing basis, pressure testing, monitoring, SCVF/GM testing, and post-frac integrity evidence.
Current Guidance
Current Directive 083 remains the controlling hydraulic-fracturing integrity reference. Current Directives 009 and 010 should be checked for casing cementing and design requirements.
