Paper Number: SPE-189725-MS
... of shale barriers are usually unknown since we do not have enough data to characterize them. Therefore, the geometries of shale barriers are important parameters to be considered in production history matching and optimization processes. Shin and Choe (2009) studied the effects of shale barriers...

... into the history matching process using a probability perturbation method (PPM) to preserve the geological consistency of a reservoir model. A PPM is a geological data integration framework which employs a multiple-point geostatistics (MPS) algorithm. The heart of this method is to systematically perturb...

... using AI techniques. The proposed method facilitates the selection of an ensemble of reservoir models that are consistent with the production history; these models can be subjected to further history matching for a precise final match. The proposed methodology does not intend to replace traditional...

... takes longer. At Hangingstone Demo area, (Demo area), there are 24 well pairs which have been producing bitumen by SAGD process. The objective of this study is to obtain a unique set of parameters, such as permeabilities and extent of heterogeneities, from simultaneous history matching using different...

...) the change in conditions from sand face to wellhead, and 3) the fluid interaction between the wellbore and reservoir. Using a thermally-coupled wellbore-reservoir simulator, a discretized wellbore model was constructed to allow a detailed history matching for the circulation period of the M-well pair...

... indicating the benefits of CLRM to maximize the reservoir performance. Typically, the workflow of CLRM consists of two main components: the Assisted History Matching (AHM) part; and the Optimization Algorithms (OA) module. A key concept here is that a single model is likely to be wrong, and so any production...

Paper Number: SPE-165555-MS
.... The leak-off rate is partially a function of the reservoir size, hence, the boundary conditions need to be described in the model to mimic the large reservoir behaviour in order to ensure the material and energy balance. Abstract History-matching is commonly used to calibrate numerical simulation...
