Typical online requirements gas-condensate facilities

Subsea-to-shore or platform solution

• Handling capability for large volumes of gas
• Downstream gas handling (either pipeline or LNG)

Large diameter pipelines and wells

• Large diameter pipelines, 10-30” (liquid build-up)
• Large diameter Wells, 6-10” (liquid loading)

Operability

• Hydrates (typically high cost risk)
• One step in the supply chain (frequent rate changes)
• Supply regularity (LNG and pipeline to consumer)
• Packing or de-packing of pipelines (buffering)
• Liquid management

Operations

• Initial start-up
• Rapid and frequent rate change
• Pigging
• Inhibitor management

The typical solution for gas-condensate production systems includes online monitoring and advisory features as summarised in the OLGA Online pages.
