Currently am working in Fixed offshore platform design. This is my first project of this kind.
In the design basis it is mentioned that " SURGE FACTOR OF 25 % ON WELL FLUID FLOW RATES AND SWELL FACTOR OF 15% ON OIL AND CONDENSTAE FLOW RATES SHALL BE CONSIDERED FOR DESIGN OF TOPSIDE FACILITES ".
My understanding is ,
1) Surge factor -- Overdesign margin for future expected well flow
Swell factor - To accomodate expansion of oil to stock tank conditions
2) Whether the above factors to be applied on volume basis or mass basis??
3 ) Application : ( considering volume basis)
Oil flow -- A bbl/d
Total well fuild flow( including oil and associated gas ) - B bbl/d i.e ( A + gas flow)
Applying swelling factor - A x 1.15 bbl/d
Appllying surge factor - ( A x 1.15) + gas flow ) x1.25 bbl/d
Above is my own understanding. Please correct me if am wrong and Guide me.
