Project Description

Data formats confirmed with Bob Will. Waiting for project description and model design.

Sep 6 2012

Data formats confirmed with Bob Will, new surfaces created with better interactions between the surfaces creating each layer (fewer intersections). Por and Perm properties have been recalculated. There will be new seismic data in another month or so. Start with the version we have. Note new figures showing the full Kevin Dome area, about 120 well tops. LANL will use mesh extents similar to the rectangle of the Small Model represented in prelim surfaces.

Bob will send new surfaces and properties to LANL to include:

1) Structural Surfaces exported from Petrel in Earthvision format. - Bob will try exporting with Z upward, otherwise we will multiply by -1. - Preferred file name convention; Earthvision scattered data format ending in ".dat" (So Earthvision can read). Surface names starting with 000 or 001 and numbered upward to top surface. This ensures we have the correct order and makes it easier using scripts. - Data summary and/or images of each surface elevation and layer isochores 2) Property data in GSLIB format including x,y,z,I,j,k, poro, perm for each cell of the Petrel/Eclipse grid. This is essentially a point data file with poro and perm value at each point. - The file size can be reduced by omitting the i,j,k fields. - Appending ".dat" allows Earthvision to import and display this data. - Data density based on data resolution. - Data summary and/or images of poro and perm for each layer

Evaluation of Prelim KD SMALL Surfaces and Property Data

Surfaces are exported from Eclipse/ PETREL into Earthvision (EV) ascii format files. These files are viewed directly with EV and imported into LaGriT for use in Meshing and Model Setup.

Creator:  Bob Will, Schlumberger Carbon Services

Subject: Kevin Dome, subsurface, static geologic model, reservoir characterization, grid files

Description:  Sample data exported from the Kevin Dome Petrel Model distributed to Flow Modeling teams to test grid format requirements and workflow. - A series of (ascii) model files for our smaller grid in eclipse format. This information is fully descriptive for an eclipse user - An ascii file in GSLIB format including x,y,z,I,j,k, poro,perm for each cell of our smaller grid. This may need to be supplemented by grid surfaces (below) and some basic info about the grid is provided in the powerpoint 20120808_KD_Model_Exports_070712.pptx. - Two ascii files for each well that has poro and perm. One file contains x,y,x,poro,perm for each log sample. The other contains the well path description (deviation) for each well. The first actually contains all of the information needed to register the poro-perm values in 3D space but the deviation data is needed if the user wants to actually associate the data with a particular well. 

	Small_Model_Surfaces.zipx - these are the surfaces from the small model at 300x300 resolution in EarthVision format. The user needs to know that I selected the option to reverse the sign of Z on export to make it conformal with normal earthvision convention.

	Smoothed_Full_Model_Surface.zipx - ? These are Alan?s full model surfaces but I have resampled them to 500x500 to make them more manageable size. Also in EarthVision format.
