| Post subject: | Analysis of grid atributes like in Geo-bodies |
Hey all, Great idea these forums. Hope I find the solution to this question I've had: I have a gridded reservoir with attribute assigned to each cell. This attribute contains info about whether a small fault was seismically identified in that cell or not (i.e. 1 or 0). These areas (with small faullt clusters) form elongated zones of cells where the fault flag represents fault zones. They could be interpreted as disconnected sand bodies though in the same grid. I would like to know whether there are any plugins or workflows that allow you to connect up these cells (with identified faults). Similar to how that can be done using the geobody method? Afterwards I would like to extract data on volume, length, height and thickness of these clustered groups of cells. I welcome any ideas as it has been nagging me fro quite some time. regards, Austin |

Couldn't you copy the attribute containing the fault info (0 or 1) and then delete all values < 1 (eg make them undefined: U with a simple if statement). This will leave you with only the cells that are in the fault zones and you could calculate the total volume of that. Does that help? |

Sorry for not replying in such a while... I actually used your proposed method and although I tweaked it all a little your idea worked. Putting a N/G and a porosity of 100% and a oil-water contact far below, and using the volume calculation module I came to the volume of the cubes in the fault zone. Thanks! |
