Summary Multiobjective history matching has gained popularity in the last decade. It provides an ensemble of diverse set and good matched models that should lead to improved forecasting. Moreover, in some cases, multiobjective history matching provides faster and more-robust convergence than the single-objective approach. In multiobjective, objective components (usually groups of them) guide the algorithm …

Abstract The paper covers green field development in a low-permeability reservoir, where water injection is under consideration. To maximize economic value, accurate well placement and key data gathering during delineation and appraisal will allow for early cash flow generation and preservation of ultimate waterflood reserves by operating above the bubble point pressure. Conversely, implementation of …

Abstract The fracturing of horizontal wells is a recently developed tool to help enable tight and shale formations to produce economically. Production data analysis of the wells in such formations is frequently performed using analytical and semi-analytical methods. However, in the presence of nonlinearities such as multi-phase flow and geomechanical effects, the numerical simulations are …

Abstract In this study we investigated full-field fine-scaled thermal reservoir models with multilateral wells that are independent of grid refinements and thus allow efficient optimization of well placements. This facilitated the production optimization and well interference study in thermal modeling framework. We observed that multilateral wells with multiple sidetracks enhanced the steam injection efficiency by …

Abstract Oil companies invest significant human and money resources on decisions about field development planning. Often these decisions have to be made based on limited information under tight time constraints. Historically, numerical simulation is one of the main tools in the process. In most cases, the investigations remain limited to single realizations or at best …
