Notas del editor

  1. Due to the explicit nature of the saturation function, the ROCM numerical computation is 100x-1000x faster than conventional simulation (seconds vs. minutes or hours) The inverse problem – finding a saturation distribution that honours material balance and individual well production – becomes solvable within minutes rather than months
