A disposal well is different from a producing oil well because it does not deplete in production over time. A disposal well can improve over time because the wells around it will extract more water the longer they produce. The amount of water a disposal well receives can increase as more wells are drilled in the area. Rising oil prices can make the disposal well more profitable since skim oil prices fluctuate with the price of oil. Longevity is a bonus for a disposal well operation.
