Petroleum Industry has a lot of uncertainties and risks in each element of its different domains starting from exploration reaching to production. Different tools are being used in order to minimize those uncertainties especially in characterizing reservoirs and defining the optimum development strategies for them. One of the most powerful tools is the numerical reservoir simulation which is considered the state of the art technique since 1990's. Numerical reservoir simulation uses certain geological and engineering findings and predicts the reservoir performance in the future stochastically. It helps a lot in maximizing the asset value and hence the project economics.

Geological Model or what is called “Static Modeling” is the most important stage in the reservoir modeling process at which we build our model to capture all structural, stratigraphical and petrophysical features. The static model is usually built by the geoscientists then delivered to the engineer to start feeding the model with the dynamic data (e.g. PVT, SCAL, Production, Pressure, VLP… etc.). But before feeding the static model, each reservoir engineer must check the quality of the Static Model to assure certain feature such as; it had been coarsened or upscaled properly, it can really mimic the fluid flow directions, it can be run by numerical solvers available in commercial Simulators without any convergence error, it is valid for the purpose it was built for and much more others.

That's why it is very important for each engineer that is willing to work on static models to have a road map of what he/she should do and what type of interactions with geoscientists needed in order to QC the static model before getting it to be Dynamic Model. Indeed, we generalized definite steps which can be considered as a template for any reservoir engineer to follow when he/she approaches to QC any static model. Those steps include all the QC elements starting from Structural aspects like faults modeling reaching to matching with electric logs and facies description. Not only the Static Model QC but also we proposed many recommendations during the Upscaling stage and how to keep your model as simple as you can. All of those were stated clearly combined with some technical details behind each step to let engineers be aware of the technicality in background and its impact.

This paper is important for any engineer dealing with reservoir modeling which will provide him with a general scheme to follow whilst QC'ing the model. This paper also targets the methodology to obtain well-defined model in order to have a better realization of our reservoir and hence better FDP and maximum asset value which is the ultimate target for any E&P company in our world.
