  1. Hi

     

    Recently I've updated from RW17 to RW20 and I noticed a fault in all of the borehole operations that display 2D striplogs. 

     

    The left bar represents the lithology while at the right you can see CPT-data. Lithology is measured from collar elevation and the CPT-data (P-data) is measured from elevation. This is something I inherited from the project in the past. However, both the lithology bar and the CPT-data should start (and end) at the same level.

    Left: RW20

    Right: RW17

     

    In RW17, the lithology bar and the CPT-data coincide perfect as you can see on the right picture. 

     

    Is there a new setting in RW20 that I missed, or is this a bug? 

     

    Kind regards

  2. Hi

     

    I was wondering where I could find instructions to upgrade a database and its accompanied models from v17 to v2021.

    Are there any specific actions I have to undertake, or should I be carefull with something?

     

    Kind Regards

  3. Hi 

     

    Is it at all possible to customize the lithology datasheet in the borehole manager? Currently you have Depth 1, Depth 2, Keyword and Comment under the lithology tab, but I would like to add another column. I've done so when clicking on datasheet.

    However, after adding other columns and saving, the extra columns have dissapeared again.

    Weirdly enough, I also can't change the column title of the newly added column (5).

  4. I've recently stumbled on problems concerning the import of I-text followed by a problem with the export.

     

    Often, I have to update a certain field of the I-text, 'Geologische formatie' in this example. Usually, I import it as an excel with multiple tables. I always choose the 'update' function in the Borehole Overwrite Options. This has always worked for me, untill now. 

    The problem is, that sometimes, RW doesn't recognize an interval that is already present in RW and is given in the excel, wich ends up in RW making doubles of the same interval (see example below).

    image.thumb.png.adff95cacce34541193f6babdb8d78db.png

    As you can see, this is not the case for every interval, but only some.

     

    Another problem I encounter is that sometimes, RW just remembers 'old' data when I overwrite it with 'new' data. This becomes clear when I make an export to excel and I see there 3 identical intervals, each with the data of a given time. But I do not always see these double or triple occurences in RW itself. 

     

    Does anyone know how this happened and how I can prevent this? 

     

    Kind regards

  5. Hi all

     

    I wanted to create an multiple tables export to an excel file when I stumbled upon following error:

    image.png.ce41ba47860a45b324b6d4d2c869bf3e.png

     

    So, naturally, I performed a database integrity check and every datatype was verified except the 'Production' as you can see below. 

    image.png.6d0e3b0132ec4828709edf1abb4e5337.png

     

    Now I'm left with the question on how to solve this problem. Has anyone else encountered this problem before? 

     

    Kind regards

  6. Hi all

     

    I am wondering how I should enter stratigraphy data when I don't know where a certain border between 2 stratigraphies is situated. 

    For example, my borehole only reaches into the first layer, which I call 'A'. The reached depth is 4m and I know now that at least the first 4m are A (but it could be more, I just don't know that). The following layer is called B, but I find no evidence at this specific borehole to allocate the layer of B to a specific depth. What is the correct way to enter this data into the stratigraphy tab of the borehole manager? 

     

    Datastructure: Depth to top - Depth to Base - Formation

    Option 1. 0 - 4 - A

                     4 - 'Nothing' - B

    Option 2. 0 - 4 - A

                   

    Option 3. 0 - 'Nothing' - A

     

    What is my best option here to enter my data? Does Rockworks (17) make a distinction between the 3 different types of input? 

     

    Kind Regards

  7. Hi Tom

     

    Thank you for your answer. Unfortunately, I am not in the position to use CutePDF. However, after messing around with the settings, I managed to create a PDF about which everyone was fairly happy. 

     

    Kind regards

  8. Hi all

     

    I am having trouble with creating PDF's of high quality. I have already tried 2 different options, but I don't seem to get closer to a desired outcome. 

    Basically I need to create a pdf of a projected alongside a location map. The first problem is that I need a different lay-out for my probings and my bores. I can get this far and append the probings and the bores to one projected section without much problem. What doesn't work out is that I need to create a location map seperate from the projected section as I want both probings and bores on my location map. 

     

    Ideally, I want the location map in the same pdf as my projected section. What I have tried so far is the following:

    • Rockplot/2D export to PDF with different settings such as pixels per inch, size, dynamic vs Fixed Sizing. I always have to make a trade off between the high pixels per inch for high quality or low pixels per inch because thin lines like the surface are barely visible in an exported pdf when I put in high pixels per inch. 
    • Reportworks: I have not explored this thorough, but the quality of the first image I created was rather poor. I couldn't read the labels of bore and probings for example. 

     

    Are there any guidelines for finding the right settings?

     

    I also have one other sidequestion left:

    Is it possible to show the distance on the line of the location map like it is shown on the projected section? 

     

    Anyway, much appreciated if someone could look into this.

     

    Kind regards

  9. Hi Molly

     

    Thank you so much. This is exactly what I was looking for. I have, however, 1 question. Filtering my boreholes on arsenic, I get 40 non-zero values across 11 different boreholes. 

    When I create the statistics report, the population (Non-null) is equal to 80. This is the exact double. Is this as intended? 

    I calculated the mean myself and this corresponds to the mean in the statistics report.

     

    Kind regards

    Vincent

  10. Hi all

     

    I am looking for a way to extract geochemical data from a specific layer. For example, I have put all the arsenic levels into the I-data tab of Rockworks (17) and I have a stratigraphy model.

    Is it possible to know all the statistics (mean, st.d., etc.) of arsenic in a layer of my choosing? I have not modelled the geochemical data, is this necessary? 

     

    Kind regards

  11. Hi everyone

     

    I am wondering if it is possible to assign a stratigraphy from my current stratigraphy model to a bore that has initially no stratigraphy.

    I tried using stratigraphic rules (infer partial unit & insert missing units) but without the desired outcome. 

    Is there another option I should try, or is this not possible at all?

     

    Kind regards

  12. Hi Edward

     

    Thank you for your comment.

    Deviated wells are not that much off a problem because the slopes of my stratigraphic layers are rather low. 

    On another note, I have over 2700 wells in an area of approximately 20 squared km, the image is quite dense. 

    I could turn of all of the wells I don't want, but that would be very timeconsuming and also proper recording from my part. 

    Alas, there seems no easier way. 

  13. Hi

     

    I was wondering if it is possible to allocate different types to drillings. E.g.: I have 3 types of drillings and I would like to give them Type I, Type II or Type III.

    Next I would like to create a projected stratigraphy section, where only drillings of Type I are projected onto the section. This means that all the other types (II & III) are not allowed to be projected onto the section, even when they fall within the 'Swath'. 

     

    Does anyone know if this is possible at all? 

     

    Kind regards

  14. Hi Tom

     

    Thank you for the quick response. The latter question is already resolved. However, I am struggling to resize my ground surface grid to the project dimensions. The ground surface grid is smaller than my project dimensions. I found the Grid | Math | Resample tool to adjust the ground surface grid to my current project dimensions. I'd like to put the nodes outside of the ground surface equal to zero, but when I use this tool, it also adjusts nodes within the ground surface grid (i.e. by sector based or filter based). 

    image.thumb.png.0db932c357a71f5155b19b47bdc7c067.png

    How do I avoid adjusting my original nodes in the ground surface grid?

     

    With kind regards

  15. Hi

     

    I'm having trouble to constrain my stratigraphy model (section) to a surface grid. 

    More specifically, the top stratigraphic layer is limited to the surface grid, so that's fine. However, the surface also cuts the layer below the top stratigraphic layer in reality; but this is not showed in the model.

     image.png.a3da1359fe06fe3bd08b069927ed2c93.png

    The blue dashed line represents the surface. How do I constrain the green layer to this surface? 

    I read somewhere in the RW17 guide that the constraining surface is only applied to the top stratigraphic layer, but this sure can't be how it's supposed to work, or am I misstaken? 

     

    On a completely different note, how do I get rid of the vertical lines in the middle of the image? 

    Thanks in advance.

     

    Kind regards
