Working with Well Artefacts in p:IGI+
Well artefacts store well site specific information, depth & deviation information, temperature information and stratigraphic information. Well artefacts play an important role in the system integrating geology, depth and samples.

How to use in practice
Wells in p:IGI+
Well artefacts, or simply wells, are fully integrated into a project. Wells store the necessary information to dynamically calculate sample true vertical depths from measured depths, assign stratigraphic information to samples and manipulate/interact with depth plots.
Wells are created by default in p:IGI+ when any data row is imported which includes well information. This must include at the minimum a well name, which is used as the unique identifier for the well artefact in the project. Wells can also be created by importing well only information from p:IGI-3 well manager files, or stratigraphy or Measured Depth-True Vertical Depth tie points from Excel files.
During import in p:IGI+ well information spread across multiple samples is merge in a very automatic and simple manner. For example if there were two files import, the first with the header and data row:
and the second:
Then in p:IGI+ a well called Stark-1 would be created first time, with the Lat and Long values given. When file 2 was imported the first values of the Lat and Long would be retained, and the user told in the import merge feedback text box that the values 52 and 2 had been discarded. However the new value for the Country.Well would be updated to now read UK.
There is no user control over the merge process to create wells in p:IGI+, and this is a deliberate choice to retain a clean, automated import and well creation process. If the user needs more control Metis Transform is the appropriate tool.
In p:IGI+ a sample can be assigned to a well either at import, or later by manually typing the well name in a cell on a spreadsheet page. Care should be taken here as typing a slightly wrong name will create a new well, however it is relatively simple to remove this new well and reassign the sample(s) to the correct well.
Once well artefacts have been created they work identically in p:IGI+ and Metis, as described in the general well artefact guide.
