  1. 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 Vincent Verswijvel
  2. 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 Vincent V
  3. 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 Vincent
  4. 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
  5. Now that I think of it, this sounds very obvious. Thank you very much, this is very helpfull.
  6. Hi Mitch Thank you for your response. I will definitely look at this. However, it may seem a little weird, but it is not preferable to model the arsenic for my project. Do you think it's possible to get the statistics from the raw input, so without modelling the arsenic? Kind regards Vincent
  7. 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 Vincent Verswijvel
  8. Hi Tom Thank you very much. The detailed explanation certainly was hepfull. I'm really happy with the result. Kind regards Vincent
  9. 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 Vincent
  10. 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.
  11. 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 Vincent
  12. 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). How do I avoid adjusting my original nodes in the ground surface grid? With kind regards Vincent
  13. 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. 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 Vincent Verswijvel
