Reduction of CAPEX & Optimization of OPEX with Innovative Ideas by Integration with Brown Field and Green Field Development to Achieve Zero Venting

Abstract

Baronia field is located in Sarawak Operations, Miri and started production in the year 1973. It consists of two process complexes BN–A and BN–B. Each of these complexes has its own satellite vent platform which are BNV-A and BNV-B. In line with PETRONAS statement of purpose ‘A Progressive Energy and Solutions Partner Enriching Lives for a Sustainable Future’, the operators had initiated to adapt sustainability as a key element in PETRONAS operations. Aligned with BDO EOR PSC venting/flaring reduction roadmap, in 2010, SKO Reliability and Integrity Team were driving two vent to flare conversion project (BNV-A and BNV-B) to be incorporated. The BNV-A vent to flare conversion project was completed at a cost of USD 9.6 million. The high cost has raised concerns to the BNV-B vent to flare conversion project as it was considered a major investment with no expected economic revenue returns. A new project, BARDEGG-2/BN EOR, came up to develop a new Central Processing Platform (BNCPP-B) bridge linked to existing facilities (BNG-B), for processing of new Non Associated Gas (NAG) fields & EOR. BNCPP-B is designed with its own flaring system for the new facilities. The green field project team prefer not to touch any existing brown field scope to avoid complications. In view of this matter, SKO Operations Readiness & Strategic Assurance team (ORSA) has been able to come up with a brilliant idea of achieving zero continuous venting and cost optimization. The proposed innovative design is exclusively from SKO ORSA team and was supported by SKO Management. In this paper we will demonstrate the innovative approached by operators in order to achieve zero continuous flaring/venting in Baronia offshore field. The results and observations post the realization of design will also be discussed. The impact has been huge in terms of enhanced production continuity and plant reliability, maximized environmental sustainability by reduction of greenhouse gas emissions, and major cost savings.
