CRA, Schlumberger & Cairn: Enclosed Flaring in Barmer

Schlumberger required a flaring solution capable of handling produced gas streams with extremely low hydrocarbon content and contamination, creating inherent combustion and stability challenges. The system needed to address the following constraints:

‍

• Very lean gas composition with limited calorific value
• Presence of contaminants requiring robust combustion containment
• Requirement for stable, enclosed combustion to meet safety and environmental norms
• Continuous operation in remote desert conditions at Barmer
• High reliability expectations under upstream production constraints

‍

The flare had to ensure consistent ignition, stable flame retention, and controlled radiation while operating with a difficult and variable gas stream.

CRA engineered and manufactured a fully integrated enclosed flaring system specifically designed for lean and contaminated produced gas applications. The solution emphasized combustion stability, maintainability, and turnkey delivery.
