public class WellBarrierSchematic extends Object implements Serializable
Well barrier schematic per NORSOK D-010 Section 5.

A well barrier schematic defines the primary and secondary barrier envelopes and validates them against standard requirements. It implements the two-independent-barrier principle from NORSOK D-010:

  • Every well must have two independent well barrier envelopes
  • Each envelope must have at least 2 tested and verified barrier elements
  • Producer wells require a DHSV (SSSV/SCSSV) in the primary envelope
  • Injector wells require an ISV in the primary envelope (NORSOK D-010 Table 36)
  • Annular pressure must be monitored (API RP 90)

Usage Example

WellBarrierSchematic schematic = new WellBarrierSchematic();
schematic.setWellType("OIL_PRODUCER");

BarrierEnvelope primary = new BarrierEnvelope("Primary");
primary.addElement(new BarrierElement(BarrierElement.ElementType.TUBING, "Production Tubing"));
primary.addElement(new BarrierElement(BarrierElement.ElementType.DHSV, "DHSV"));
primary.addElement(new BarrierElement(BarrierElement.ElementType.XMAS_TREE, "Xmas Tree"));
schematic.setPrimaryEnvelope(primary);

BarrierEnvelope secondary = new BarrierEnvelope("Secondary");
secondary.addElement(new BarrierElement(BarrierElement.ElementType.CASING, "Prod Casing"));
secondary.addElement(new BarrierElement(BarrierElement.ElementType.CEMENT, "Casing Cement"));
secondary.addElement(new BarrierElement(BarrierElement.ElementType.WELLHEAD, "Wellhead"));
schematic.setSecondaryEnvelope(secondary);

schematic.validate();
System.out.println("Passed: " + schematic.isPassed());
