Integrity Log Review

Module 1 - Pressure Test Review

def pressure_change_rate(p_start, p_end, hours):
    if hours <= 0:
        return None
    return (p_end - p_start) / hours

def percent_pressure_loss(p_start, p_end):
    if p_start == 0:
        return None
    return 100.0 * (p_start - p_end) / p_start

For each pressure test, document:

• test volume and fluid type
• hold period
• acceptance threshold
• temperature correction applied or not
• whether the reported pass/fail criterion was objective or narrative only

Module 2 - Evidence Matrix

def evidence_vote(*flags):
    """
    Count positive indicators across report types.
    """
    return sum(1 for f in flags if bool(f))

Use a matrix like this:

One positive indicator is usually not enough for a confident call.

Module 4 - Common Review Findings

Output Format

When using this skill, structure the answer as:

1. Documents reviewed and reference depth basis
2. What each document actually proves
3. Leak-path evidence matrix
4. Most likely interpretation with uncertainty
5. Best next log, test, or workover discriminator

Integration Points

• Use pnge:well-integrity-barriers for the barrier and pressure framework.
• Use api-well-standards for casing and cement design context.
• Use pnge:materials-fracture-mechanics when crack growth or fatigue is implicated.
