In the exploration and appraisal lifecycle, if the asset economics are confirmed for development the process then moves to the reservoir development lifecycle where detailed analysis and asset modeling provides information needed for strategic development planning.
Asset teams gain understanding of their asset’s potential and uncertainty through reservoir characterization modeling, the process of integrating subsurface G&G data to create a static 3D earth model that provides critical information for the next phase of lifecycle activities. Residing on a single collaborative platform, Landmark DecisionSpace® Earth Modeling provides companies a way to seamlessly integrate all their G&G subsurface data to create a high resolution earth model in a cross-disciplinary effort while preserving data consistency. The resulting earth model offers a clear understanding of the reservoir geometry, and rock and fluid properties along with their uncertainty.
Once you have characterized the reservoir, reservoir simulation is used to predict the potential flow of oil, gas, and water through the reservoir. The impact of proposed operating plans on recovery efficiencies can be modeled, from which an optimized plan can be devised and validated. The reservoir simulation model combines the earth model, well locations, and completion design, along with well controls imposed or proposed during the simulated time period. Predictions of future production can be made more accurate by including surface pipelines and facility behavior in the simulation model, and determining their potential effects on the performance of the wells. With Landmark Nexus® Software Suite, companies can create reservoir simulation models most representative of their assets behavior for field development strategies.

Validate Model Against History
Due to the uncertainty in the earth model properties, predictions based upon it will also be uncertain. To reduce earth model uncertainty, any historical production data that exists for the asset can be used in reservoir simulation to determine whether the field’s history is reproducible by the simulator based upon earth model properties. This calibration step, known as history matching, requires multiple simulation runs with properties chosen in accord with the distribution of properties in the earth model, and finding one or more sets of properties which lead to the observed well data being matched by the simulated wells. Companies can efficiently history match their reservoir simulation model against observed production data with Landmark Nexus® Software Suite.
