A well has initial production rate of $1,100$ b$/$d and exhibits hyperbolic decline with b value of $1\mathrm{.}7.$ The well has already produced $820,000$ bbls of oil over $4$ years and the current rate is $350$ b$/$d$.$ The initial decline rate is $0\mathrm{.}85/$year$.$ If the abandonment rate is $3$ b$/$d$,$ what is the EUR for this well? Assume that the terminal decline rate is $0\mathrm{.}1/$year$.$
