This case study addresses the elimination of routine flaring of high-CO₂ associated gas from a Libyan offshore field, where gas composition has historically limited utilisation and contributed to ongoing flaring.

An integrated processing scheme was developed and evaluated using process simulation, combining offshore pre-treatment and membrane separation with onshore gas handling to recover CO₂, enable fuel-gas use and meet export sales-gas specifications. The project also highlights key operational constraints, including gas composition, offshore weight and safety limitations, and export specification requirements.

The recovered CO₂ is allocated to enhanced oil recovery, positioning the project within a CCUS framework and supporting the economic viability of the development. The presentation will share key technical results, operational constraints and lessons learned from the case study, including how CO₂ separation and utilisation can reduce flaring while improving associated-gas value.
