    • Development Of Efficient Constraint-Handling Approaches For Well Placement Optimization 

      Bellout, Mathias Chakib Rodriguez; Volkov, Oleg (Chapter, 2018)
      Efficient constraint-handling methodology is developed to solve for a set of concurrent geometric well placement constraints. This implementation enhances constraint-handling capability such that expert knowledge may more ...

    • Gradient-based constrained well placement optimization 

      Volkov, Oleg; Bellout, Mathias (Journal article; Peer reviewed, 2018)
      A novel well placement gradient approximation methodology is developed based on performing finite difference approximations of augmented Lagrangian derivatives within the adjoint formulation. The methodology is efficient ...

    • Gradient-based Production Optimization with Economic Constraints 

      Volkov, Oleg; Bellout, Mathias Chakib Rodriguez (Chapter, 2016)
      This work develops an analytical framework to study the effects of enforcing simulator-based constraints while performing gradient-based production optimization. In particular, this work studies how the enforcement of this ...

    • Gradient-based production optimization with simulation-based economic constraints 

      Volkov, Oleg; Bellout, Mathias (Journal article; Peer reviewed, 2017)
      In reservoir management, production optimization is performed using gradient-based algorithms that commonly rely on an adjoint formulation to efficiently compute control gradients. Often, however, economic constraints are ...
