Full field reservoir simulation projects in West Siberian Basin and Algeria. Studies included development of new simulation models as well as the review of existing models. Simulation studies conducted to verify and increase reserves, provide guidance on mature field development, define efficient waterflood patterns, identify waterflood inefficiencies, and provide a development path for bypassed pay. Primary software used for simulation was Eclipse with additional work using Nexus.
