A gas reservoir has recently been discovered. It has a volume of $2000$ acres$*$ft$.$ The average porosity isestimated to be $25\%.$ If the water saturation is $15\%,$ and the formation volume factor at initial conditionsis calculated to be $0\mathrm{.}00333$ ft$3/$scf:a$.$ What is the volume of the gas initially in place in ft$3?$b$.$ What is the volume of the gas initially in place in acres$*$ft$?$c$.$ What is the connate water volume?d$.$ What is the reservoir pore volume?
