The optimal configurations of the injection and producer wells are chosen using the differential evolution approach and particle swarm optimization techniques. The technique was programmed for the numerical...

... in an economical model at the three different oil prices and the breakeven oil price was found to be $48.59. A Monte Carlo risk analysis was carried out with 1000 iterations of randomly generated oil prices resulting in an average NPV of $364.84MM, the cash at risk of 95% resulted in $557.09MM and the probability...

Maximization of the net present value (NPV) is set as the objective function with well spacing, fracture conductivity, fracture half-length as the control variables. 3 well spacing optimization workflows are then developed comprising...

...) This is the difference between the total revenue and the expenditures. Expressed as: (13) NCF = TR − TC Where: TR = Total revenue ($) TC = Total cost ($) NCF = Cash flow ($) Calculate the net present value (NPV). Net present value is the net income that is accrued from the stimulation taking note...
