Daily Update - Mohammad Elkady - (July-05-2022)

1.  What did I do today?

Today, I attended the first day of a two-day online CMG course about IMEX and CMG workflows

2.   What did I find interesting/Work on?

General Notes

            - To access different manuals, go to CMG Documentation browser in launcher.

            - Cloud CMG can run up to 32 processors

            - Builder can read 2 types of geological data files: Contour maps and Mesh maps that includes x and y points and properties.

            - You can modify the properties for a specific set of blocks by the Edit Reservoir Property Icon

            - Sectors can be usefully to monitor a specific are of the reservoir.

            - Types of blocks

                        ○ Active (Contributes to the flow)

                        ○ Null (Inactive)

                        ○ Pinch (Inactive vertically) 

            - Dual Por

                        ○ Flow from matrix to fracture and fracture to fracture

                        ○ Each matrix is divided into submatrices (MIN)

                        ○ For SUBDOMN the matrix is divided into layers

            - Dual Perm

                        ○ Flow from matrix to matrix and fracture to fracture and fracture to matrix

            - Por = Por (i) EXP(Cr(P-Pref))

            - For PVT you can use Winprop to match lab data and then import it to builder

                        ○ Or if you do not have lab data, use Correlations

            - Restart: make the simulator start from a specific time step (Not from the very beginning) to reduce the simulation time

            - Make sure to check if you need your oil compressibility to be a function of pressure or not from the PVT table and then assign Undersaturated oil compressibility

            - Define rock type for each rock layer!!! 

            - Rock compressibility has an effect on the reservoir pressure and water cut

            - You can plot properties vs distance using the Profile tab in RESULTS

3.  What will I do next?

Next, I will attend the second day of the course till the IT can solve the issue with CMG software
