Working with Well Artefacts
Overview
Well artefacts store well specific information, location data, depth & deviation information and stratigraphic information. Well artefacts play an important role in the system, integrating geology, depth and samples.
Version: 1.22.0.2+ (Mar 2020)
Usage: Double-click well artefact in artefact manager,
Drag & drop well artefact into the project workspace,
How to use in practice
Well Artefact
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 in p:IGI+.
To create a new well manually select the New Well icon on the toolbar. The minimum criteria required when creating a well is just a well name. Normally wells are created on import (p:IGI+) or Project merge (Metis Transform).
To rename a well name right click on the well artefact and enter an amended well name. A well can only exist once in a given project with a particular name, so if a duplicate is entered it will have the characters "(1)" appended to the name to indicate this is a different artefact.
To harmonise well names or to remove an unwanted well (and associated samples) from a project, use the Delete function from the right click menu on the well artefact. At this point you will be presented with the following options of what to do with the samples currently assigned to the well being deleted:
Delete samples associated with the well;
Assign associated sample to a different well (this is the act of pseudo-harmonising your well name);
Leave samples in the project unassigned to a well (i.e. in the case of mis assigned outcrop / surface samples).
Populating Well Data
For a well, all data associated with Location, Depth and datum information, Directional drilling data, Stratigraphy and Drilling are managed through the well artefact accessed through the Artefact Manager. Wells can also be accessed through the well icons displayed on maps (currently p:IGI+ only). Most well properties can be viewed through page views, but on pages the well information columns are display only columns.
The well artefact contains multiple tabs to store the various well information:
- Well info- general information including the well type, along with any user comments
- Location - well coordinate and region information
- Depth - well site and borehole depths and datum’s
- Well Deviation - well deviation surveys, or a list of tie points for MD -> TVD conversion
- Chronostratigraphy & Lithostratigraphy - tables for well stratigraphy. Linked to the relevant Lstrat and Cstrat.Geol analysis group properties
- Drilling - operator and drilling event information
All properties in the .Well analysis group are displayed in the well artefact.
Importing well data
Well data can be imported along with general sample data, but will be auto-merged in p:IGI+. If you specifically want to import well data from a well data only source, the following options are available:
- Bulk import of general well information - suitable for 'standard well properties' which are simple strings or numbers;
- Bulk import of well stratigraphy tops - suitable for importing new or updated tops information for chrono- and litho-stratigraphy;
- Bulk import of tie points - suitable for importing new or updated tie points mapping measured (drillers) depth to true vertical depth;
- Bulk import of well information from p:IGI-3 well manager files.
Managing well data (1.22.0.2 onwards)
Having spent a lot of time populating well information, it is important that as a user you can share this information between projects. This is achieved using the Export wells... option from the Project menu. This allows you to export all the information in all wells in the project into a p:IGI+ file (*.igi_well). These p:IGI+ well files can then be imported into other projects using the Project -> Import well data -> Import p:IGI+ well file... menu item.
