Dear List, I would like to know if it's possible execute a specific algorithm (e.g. filtersim) from the MS-DOS command line. If it's true, what is the syntax? Thanks, Eugênio. _________________________________________________________________ O Internet Explorer 8 quer te ajudar a navegar seguro.

Dear all, I just want to get your ideas on a direct block simulation of the orebodies to express the uncertainty in the grade variation within the geological section of interest. As far as the simulation is concerned, the short range variability is of great importance in terms of the accuracy of the simulated realisations. However, if the drilling pattern is 75mx75mx0.25m and if the variography is conducted based on this block size then I wonder how the short range variability can be taken into account in the simulation process. would not we need a closer drilling pattern to assist us with generating a meaningful variogram? If possible, could you share your ideas on that please Regards, Oktay |

Hi Firat, Thanks for the complete explanation of that problem. However I was not bale to reproduce your results. I loaded your 4 points example and create a cell in the middle by a) loading a second file with only one point in the middle (1,1,-1) b) create a new grid centered at (1,1,-1) and c) load your 5 points file. In all cases I got 1150. The grid can be created with : NewCartesianGrid test_grid::1::1::1::1.0::1.0::1.0::1::1::-1 Rembember that the origin are the coordinates of the *center* of the lower left corner, in the particular case of a one cell grid, it is also the center of the grid. Could you send me more info about how you created or loaded your first case that generated the mismatch.

Hi Kara, Both sgems and Wingslib can do KT. KT will take care of the "non-stable" mean but not of the spatially varying variance (is that what you mean by "non-stable" variance). The main challenge of KT is that you must provide the variogram of the residuals. But to get the residuals you need the trend which can be calculated once you know the variogram of the residuals, not very helpful! These techniques (KT and kriging with an external drift (same equations)) are back under the umbrella of residual kriging. Worth looking at it, since some techniques of estimating the residuals had been proposed.

Dear all
I would like to do KT (kriging with a trend) on my data which show non-stable mean and variance.
But it the the first time for me to do this type of kriging. Would you please provide me with a quick help on execution of this type of kriging. I know that I have to model the trend first, But I do not clearly know how? Does SGeMS and WinGslib both can do KT?
I appreciate any help so much.

Hi Alireza. mGstat (http://mgstat.sourceforge.net/) contains a Matlab interface to SGeMS that lets you call SGeMS from within Matlab and manipulate the parameter file controlling SGeMS. If you intend to try the example below, I suggest you download mGstat from SVN (http://sourceforge.net/projects/mgstat/develop) as the support for SGeMS has been updated a lot since the last release. At the moment the semivariogram computaton of SGeMS cannot be performed using the commandline interface, and therefore this is not available in mGstat. You can however manually fit semivariogram models in Matlab (see below) Say you want to perform sequential Gaussian I suggest you try out the small example in Chapter 3.1 in the online documentation (http://mgstat.sourceforge.net/htmldoc/chapSGEMSuse.html#SGEMS_seqsim) In short to to get a default SGSIM XML-parameter file loaded into matlab: -- S = sgems_get_par('sgsim); % Loads a default SGSIM parameter file -- All options for controlling SGeMS is in the matlab structure : S.XML.parameters If you want to change the variogram model, you should change the structure below S.XML.parameters.Variogram -- >> S.XML.parameters.Variogram ans= nugget: 1.0000e-003 structures_count: 1 structure_1: [1x1 struct -- To run 10 simulation with increasing range do for example: -- for i=1:1:10 r=i*10; S.XML.parameters.Variogram.structure_1.ranges.max=[r]; S.XML.parameters.Variogram.structure_1.ranges.medium=[r]; S.XML.parameters.Variogram.structure_1.ranges.min=[r]; S=sgems_grid(S); subplot(4,3,i);imagesc(S.x,S.y,S.D(:,:,1)'); end -- You can also specify the variogram model using a shorter notation (same format as when using GSTAT) (only available in the SVN version): -- S.XML.parameters.Variogram=sgems_variogram_xml('0.1 Nug(0) + 0.4 Exp(10) + 0.5 Sph(40,30,0.2)'); -- In mGstat you will find a few m-files that should help you manully fit a semivariogram model to the experimental semivariogram obtained from your data. Check out 'semivar_exp_gstat.m' I hope this can help a bit.

Hi Carolina, 1 - Original data 2 - Variogram of the residual 3- the lvm program automatically removes the mean, performs Sk and add back the mean. So the final output is the estimated residual with its colocated mean. Note that for lvm the data must be on the estimation grid since it needs that grid to retrieve the local mean. (It that cannot be done, then I would suggest to manually remove the residuals, perform SK with zero mean and add back the residuals) Regards, Alex On Mon, Nov 30, 2009 at 12:14 AM, Carolina Guardiola <c.g...@ig...>wrote: > Hello all, > > I have some questions about Kriging with LVM. > > 1.

Hello all, I have some questions about Kriging with LVM. 1. About the hard input data, should correspond to the original data or the residuals? 2. And the variogram, is it the variogram of the residuals? 3. Should I add the mean to the krriging estimates to the transform the results to the original variable?

Hi I have run into a problem using Markov Model 2 type Cokriging. It seems that whenever I use a 'contirbution' (should be the sill value according to the SGeMS book) larger than 1-2 i get into trouble. I could reproduce the 'effect' using the Ely data set distributed with the SGeMS book: Figure 7.8 from the book contains an example of MM1 type cokriging and the parameter file is available on the disk that comes with SGeMS. If I try and use MM2 type cokriging on the same data set, I get some results that look reasonable (cokriged values lie between 2 and 8). Here the variance of the secondary data is about C_22.contribution=1.15. As an example I made a copy of the secondary data set, with a variance of 10 (same mean). When I run MM2 type cokriging again, with the secondary data with a variance of 10 (C_22.contribution=10), I believe I should get identical results as the above example. Instead I get wildly varying estimate with extreme values of -1500 and 300000. I uploaded this small example to : http://dl.dropbox.com/u/2620143/MM2_EXAMPLE/MM2_EXAMPLE.zip mm2_org.par : MM2 style cokriging using original secondary data from Ely data ('Ely1_pset.samples') mm2_var10.par : MM2 style cokriging using Secondary data with a variance of 10 ('Ely1_pset.sample var 10') So in short, whenever is use MM2 type Cokriging using a secondary data set with a variance much above 1, I get useless results. Do I make an error setting the MM2 parameters? Or, maybe the Is a problem with MM2 type cokriging in SGeMS ? - Thomas |

Dear SGEMS's friends, I am new in SGEMS and I am doing reservoir history matching in matlab. I like to know how I can call SGEMS from matlab to create variograms and make use of the created variogram to do 2D Kriging. Any comment regarding import, export, from/to Matlab/SGEMS and format files is appreciated. Best regards, Alireza, |
