1.Technical Performance

Maximize Ultimate Oil Recovery

maxRF(t = 3000 h)

u=[k,ϕ,Q, Cpoly​,VDP​]

Bound constraints only (Table 5)

2.Economic Performance

Maximize Net Present Value Profit

maxNPV(topt​)

where \(\:{\text{t}}_{\text{opt}}\) is the optimal injection duration

u=[k,ϕ,Q, Cpoly​,VDP​]

Bound constraints (Table 5) with implicit economic constraints via the NPV objective function
