The significant increase in using reservoir simulation models poses significant challenges in the design and calibration of models. Moreover, conventional model calibration, history matching, is usually performed using a trial and error process of adjusting model parameters until a satisfactory match is obtained. In addition, history matching is an inverse problem, and hence it may have non-uni...

Reservoir modeling is a critical step in the planning and development of oil fields. Before a reservoir model can be accepted for forecasting future production, the model has to be updated with historical production data. This process is called history matching. History matching requires computer flow simulation, which is very time-consuming. As a result, only a small number of simulation runs ...

This work presents a technique to integrate production data into the reservoir characterization workflow. The application of the technique ensures that the construction of earth models for reservoir simulation will be geologically sound and consistent not only with all the observed static and production data, but also with the earth modeling workflow philosophy, regardless of its complexity. Th...

23 Although reservoir flow simulation is a mature technology, there is a general lack of understanding in the oil and gas industry as to when it should be applied, the limitations of it and how recent technical improvements have changed simulation. Streamline models have dramatically changed simulation work and made predictions better. Simple workflow and quality control issues are absolutely c...

This study discusses a new workflow for fracture characterization and modeling using geophysical (microseismic and 3D surface seismic) data along with independent reservoir information (such as well logs). The framework is ideally suited for unconventional environments such as shale and tight reservoirs where modern technologies such as the use of hydraulic fracturing and passive seismic monito...

The objective of this study is to demonstrate the power of integrating rock physics theory, measurement and simulation to improve facies prediction in an unconventional limestone and shale reservoir. Reliable facies prediction is a challenge in unconventional reservoir characterization because of complex geological heterogeneities. Both deterministic and probabilistic approaches are commonly us...
