1Fault Throw BackgroundThe offset along a fault can be measured by using the Measure Distance tool on faults that have been filtered for a certain horizon.Measuring this distance at several places along your faults will give you an approximation of the vertical displacement of a horizon.For more accurate data,you can use this workflow that calculates the exact throw at a regular interval along all your faults.ResultThe workflow calculates the throw along given faults for a specific horizon.This will be outputted as a point set with a Throw attribute.Intermediate results of this workflow that will be kept are a folder containing fault sticks for all faults in the model,and a polygon and point set that outline the intersection between the faults/fault sticks and the horizon.Prerequisites For this workflow one needs to have a Model with faults and horizons,for which you want to calculate the throw.These will be dropped into the first few lines of the workflow as input data.The project already contains some Reference Data that will be used during the workflow.These can be copied over to your project,when also transferring the Workflow.Alternatively,you can create your own.The workflow calculates the throw as distance along the pillars of the 3D grid.One can check the settings for the fault throw point set that is created to get more insight into the displacement along the faults for a given horizon.Under statistics the range and average values can be viewed,and in the histogram tab one can have a closer look at the distribution of the fault throw.The output point set can be used to make a surface with a throw attribute,allowing you to have a clear visual display of the displacement.Workflow SpecificsWorkflow Specifics Petrel Version 2009.1 Domain Geology Modules Geoscience Core or Combined Core Expert Level Intermediate 名师资料总结-精品资料欢迎下载-名师精心整理-第 1 页，共 4 页 -2名师资料总结-精品资料欢迎下载-名师精心整理-第 2 页，共 4 页 -3名师资料总结-精品资料欢迎下载-名师精心整理-第 3 页，共 4 页 -4名师资料总结-精品资料欢迎下载-名师精心整理-第 4 页，共 4 页 -
