A drawdown test was conducted on a discovery well. The well was allowed to flow at aconstant flow rate of $175$ STB$/$day$.$ The fluid and reservoir data is given below:$=15\%,$ h $=30$ ft$,$ ct $=18\backslash$times $10-6$ psi$-1$ rw $=0.25$ ft$,$ Pi $=4680$ psi, $$o $=1.5$ cp$,$Bo $=1.25$ bbl$/$STBThe drawdown test data is given below:t $($hr$)$ pwf $($psi$)0\mathrm{.}643881\mathrm{.}243671\mathrm{.}843552\mathrm{.}443443\mathrm{.}643346\mathrm{.}043188\mathrm{.}4430912\mathrm{.}0430024\mathrm{.}0427836\mathrm{.}0426148\mathrm{.}0425860\mathrm{.}0425372\mathrm{.}0424984\mathrm{.}0424496\mathrm{.}04240108\mathrm{.}04235120\mathrm{.}04230144\mathrm{.}04222180\mathrm{.}0420618|$ P a g eCalculatea$)$ Average permeabilityb$)$ Skin factorc$)$ Additional pressure drop due to skind$)$ Pore volumee$)$ Drainage area
