Question $1$

Experimental data on a bottom hole sample of reservoir liquid taken from an unknow oil field to determine the solution gas and FVF as functions of pressure. The initial pressure and temperature of the reservoir was $3600$ psia and $160F$ respectively. All the measurements were taken at $160F.$ The results are:

$\backslash$table$[[$Pressure $($psia$),\backslash$table$[[$Solution Gas $($SCF$/$STB$)$ at$],[14\mathrm{.}7$psia and $60$F$]],\backslash$table$[[$Formation Volume$],[$Factor $($bbl$/$STB$)]]],[,,],[3600,567,1\mathrm{.}310],[3200,567,1\mathrm{.}317],[2800,567,1\mathrm{.}325],[2500,567,1\mathrm{.}333],[2400,554,1\mathrm{.}310],[1800,436,1\mathrm{.}263],[1200,337,1\mathrm{.}210],[600,223,1\mathrm{.}140],[200,143,1\mathrm{.}070],[,,]]$

$($a$)$ Plot the gas in solution vs pressure

$($b$)$ What factors affect the solubility of gas in crude oil?

$($c$)$ Was the reservoir initially saturated or undersaturated? Explain.

$($d$)$ Does the reservoir have an initial gas cap?
