scanguy,
zdas04 gave you a quite comprehensive answer in the previous thread.Your question is however difficult to answer as this is related to several disciplines as per the list hereafter which is not exhaustive:
1) type of reservoir and reservoir matrix , type of well completion and sand packings (if any for loose sand reservoirs);
2) type of produced fluids -gas,condensate,oil,waters and their physical properties (dedensity,viscosity,etc)and composition,solids entained,flow rates,etc
3)reservoir simulation jobs,acid or fracture jobs to improve reservoir permeability;
4)stage of reservoir production when pipeline pigging is done- start up,maturity,etc as the reservoir fluid composition will change and quantity of entrained solids will increase ,
5) corrosivity of the process fluids, level of the upstream separation if any,state of the pipeline;type of pigging,etc
6)the most important,the design of your slug catcher (capacity of each section for a proper separation and then accumulation ) vs. all above points and vs.the liquid/solid volums expected.
So you may have to get an answer from each concerned Specialist for all above points and as such the informations you are looking for.
