Q2) A) Using Ros and Gilbert methods, calculate the choke size for the following condition of specific oil well, flow rate is 350 bbl/day, well head pressure is 1200 Psia, GOR= 450 scf/stb. B) For the resulted choke size from (A), and for both methods, if we need to increase the flow rate to 600 bbl/day, what will be the Pwh? Correlation b a 37.95 Gilbert 3.86*103 0.546 1.89 0.031 Ros 4.26*10-3 0.500 2.00 74.7. 520
