In summary, the paper will explain in detail the systematic approach that was used to identify the root cause of the flaring in Birba Gathering Station using the trip data. A technical and economical evaluation was performed to identify the ALARP (As Low As Reasonablely Practical) option which is now selected for implementation. Once the critical flaring contributors were identified, a number of concepts emerged how flaring can be reduced by improving the compressor availability and/or sparing. history trends, trip reports, etc.) and highlighted the critical role of the compressors uptime. To adhere to a practical minimum flaring in PDO, a flare reduction project for BGS was initiated.Īs a first step, the main causes of the flaring in BGS were identified by analyzing actual field data (i.e. ![]() Flaring in BGS has traditionally exceeded 300 kSm3/d. The station consists of number of compression units where the gas is compressed to ~470 bar before it is injected into the reservoir. Realizing the need for gas conservation, PDO has given more focus on flare reduction projects reflecting this in the business planning.īirba Gathering Station (BGS) is the first high sour facility in PDO where associated gas is injected for pressure maintenance purposes. The demand for natural gas is increasing with expansion of Enhanced Oil Recovery (EOR) projects within PDO (for example, miscible gas injection) and increased end user consumption across Oman. In Petroleum Development Oman (PDO), the story is different. Of these projects that aim to reduce the flaring from current 300 KSmĪbstract Gas extracted from crude oil is often exported as sales gas. For example, BGS flare reduction project is on planned to reduce the flaring even further.

Since then, eight "Replicants" were contracted to Brazilian shipyards and the first unit should be producing next year.ĭespite the success of standardization, in current scenario of cost reduction, incrementing the capacity of new FPSO units is a major option to be evaluated. These units are operating with very good results. The first standardized projects developed by Petrobras, were the P-58 and P-62 FPSOs, two similar units to operate at Baleia Azul and Roncador fields, respectively. This initiative has proven to be applicable to a wide range of crudes and several units have been contracted since. This perception motivated a movement towards standardization and a radical change in design philosophy. This vast experience showed that eventual optimization obtained with tailor made solutions tended to lose attractivity, regarding schedules and costs, when compared with identical projects. At that time, Petrobras had already had a long experience designing, contracting and participating in offshore production units. The standardization process was initiated nearly a decade ago under a thriving scene of the oil industry.
