Four-dimensional fluid flow data is received that is associated with a time dimension and I, J, and K dimensions. The four-dimensional fluid flow data includes, for each of plural time steps, a fluid flow amount for the respective time step and for a respective I, J, K cell. Using the four-dimensional fluid flow data and for each of plural time steps, a four-dimensional geocellular model is determined having I, J, K and t dimensions and indicating, for each I, J, K, t cell, an amount of a fluid flowing through the I, J, K cell for a respective time step t. A three-dimensional time-independent model is determined for the I, J, K cell. A two-dimensional time-independent model is determined that includes a cumulative fluid flow amount for each I, J cell.

A wellbore system and a method of forming the wellbore system, where the wellbore system is made up of a primary wellbore that is disposed entirely above a producing zone and lateral wellbores that extend from the primary wellbore into the producing zone. By penetrating the producing, or target, zone with the lateral wellbores, fractures in the target zone can be better avoided thereby increasing the potential amount of recoverable hydrocarbon. Optionally, wellbore systems are included that have more than a single primary wellbore. Further disclosed is a method of maximizing wellbore production by selectively blocking designated lateral wellbores in which water or other non-hydrocarbon fluid is detected.
