3.4 Release Trajectory bug fix — WellboreStationTrajectory. Fixed bug which would prevent plots from deviating if the starting depth was equal to 0. Improved ergonomics in the demo: rubberband is not supported while deviated Fixed broken hyper-links in documentation Fixes for SimpleLabelDecorationPainter, DynamicRightLabelLayoutStrategy and DynamicLeftLabelLayoutStrategy to insure labels pin to the edge of the viewport instead of partially rendering off-screen. Changed cement.svg to be light grey instead of candy stripes. 3.3 Release Removed deprecated WITSML parser and associated classes. Fixed bugs in TrueVerticalDepthTickGenerator. Deprecated TrueVerticalDepthTickGenerator.setIsShowingDeviation as it now does nothing. In this release, we have added support for wellhead equipment. We have an SVG file for them that is wellhead.svg in the usual package. This equipment is treated specially by the toolkit It is above ground (at negative depth) It is not stretchable It cannot be deviated The label tether for it is drawn horizontally We added a new class, Wellhead, to represent the wellhead equipment. WellboreTestSource.WellboreType got two new sources that have wellheads: SIMPLE_WELLHEAD, and OTHER_WELLHEAD. You can see the new wellhead in action by running the demo with an argument of "TEST" (without quotes) and then picking one of these two sources from the application menu bar at the top. This release does not provide support for declaring wellhead equipment in our xml files; the wellhead must be added to the wellbore programmatically. To add a wellhead you should use some code like the following ```xml // creating the wellbore instance to use, giving it the name example Wellbore rtn_wellbore = new Wellbore("Simple"); ... // create the first completion string CompletionString completion1 = new CompletionString(); rtn_wellbore.getSubsurfaceCompletion().add(completion1); Wellhead wellhead = new Wellhead(depthUnits, new DiameterMeasurement( new OuterDiameter(30, diameterUnits)) ); wellhead.setDescription("Wellhead"); completion1.add(wellhead); ... ``` The class SubsurfaceDepthIntervalObject has two new methods preserveAspectRatio() (default implementation returns false) and isDeviatable() (default implementation returns true). The new Wellhead object has implementations of these methods that return the opposite. This release does not support using wellhead equipment with multiple completion strings. The interface DepthIntervalCompressionStrategy has a new method double getPositionAtDepthIntervalIndex( int index). We changed the demo zooming behavior to preserve the aspect ratio when necessary. We fixed a bug that caused wellbore's containing a Hole to have their completion string positioned incorrectly. We made changes to the labeling strategy. The strategy now aligns the left edge of the labels when there is room, and has improved the vertical position of the labels so they are closer to the anchor point. DynamicLeftLabelLayoutStrategy and DynamicRightLabelLayoutStrategy have a new method setLeftLabelEdgeHorizontalThreshold(double threshold) We fixed an error in drill bit.svg where some of the small circles were misplaced. Changed demos and tutorials so that they all build the GUI on the Event Dispatch Thread to follow the guidelines from Oracle. Changed the demo to fix a GUI freeze, and to not print out its model structure. 3.2 Release Notes Added user guide and tutorial documents. Added labels to deviated schematics. Including easy filtering of schematic components and the ability to easily create lithology behind the wellbore. Clarified unsupported features for deviated schematics: multiple strings and uncompressed view. Fixed bug in TransformedShape.applyTransform Textures for cement (CementCompositeShape), and gradient fill for hollow shapes. Added getDepthRange to WellboreTrajectory Major rework and testing of WellboreStationTrajectory Deprecated DeviatedNormalizedDepthIntervalCompressionStrategy and its associated Builder. Restructured Deviated & Compressed shapes; Made StandardCompressor separate class. Added new DeviatedCompressionStrategy and new interface CompressionStrategy Minor fixes that permit users to have a custom SVG map with a deviated schematic. The changes are to DeviatedCompressedWellboreMechanicalShapeBuilder. This class now Has a new getter method for the compression strategy: getCompressionStrategy. This allows users to change the properties of the compression strategy when needed. The default no argument constructor sets the horizontal scale factor for the default compression strategy to 150. This value is a sane and useful default which is used by many of our tutorials. The second constructor that used to take only a SubsurfaceSchematicShapeFactory now has a second argument. It now takes a DepthIntervalCompressionStrategy in addition to a SubsurfaceSchematicShapeFactory. This change allows users to specify both the shape factory and the compression strategy of their choice. Details of the API changes can be found in wellschematic_32changes.txt. 3.1 Release Notes For the 3.1 release, J/WellSchematic moved up to JDK 5, and all collections were generified. Many improvements were made to the printing, see the J/CarnacPro release notes. Additionally, the new print to scale feature was completed in this release. This necessitated a change in the requirements that applications must follow in order for printing to work properly. The changes for 3.1 are the following: Added support for deviated schematics. Some classes were added to the API, and the data schema now have new elements. The new schema is viewable in schemas/wellboretrajectory.dtd . We have a new tutorial DeviatedCompressedWellboreMechanicalShapeTutorial that shows how to use deviated schematics. Example data files with trajectories are provided in tutorial/JWellSchematic/wellschematic files wellbore_with_trajectory.xml , wellbore_with_left_U_trajectory.xml , and wellbore_with_right_U_trajectory.xml . The demo, WellboreMechanicalShapeDemo , will show deviated schematics if the input file contains a trajectory. Deviated schematics are only supported with compression; the linear view is not supported. Some of the new classes are TransformedShape , DeviatedCompressedWellboreMechanicalShapeBuilder , and DeviatedNormalizedDepthIntervalCompressionStrategy from the Well Schematic Visualization Toolkit. Modified class the WellboreTrajectory: removed old method convert that returned a TVD, replaced it with a new method that returns a Trajectory3D. Improved layout of labels when being used with JWellLog. To clarify, the WITSML examples currently in the toolkit are using an unreleased draft of the spec. If you have interest in the released WITSML spec, contact sales@int.com regarding our WellBore Viewer product and any plans for the J/WellSchematic toolkit. The API changed for 3.1 somewhat for Schematic To Symbol Map, Well Schematic, and XML Parser. A few deprecated classes and methods were removed. 3.0.2 Release Notes This release added new svg parsing abilities based on the Apache Batik library. The new parsing ability is found in the J/CarnacPro package com.interactive.jcarnac2d.util.svg. The old parser in J/CarnacPro com.interactive.jcarnac2d.model.svg is now deprecated and will be removed. J/WellSchemactic is now using this new Batik based parser. 3.0.0 Release Notes The 3.0.0 release shows lots of changes and improvements. J/WellSchematic is now integrated in the the J/GeoToolkit. J/WellSchematic now allows the user to add smart scaled symbols such as casing shoes and perforation symbols. The user can now have more than one completion string, and have a completion element that is not associated with a completion string. Here are the API changes to wellschematic.jar. Here are the API changes to wellboredata.jar. Q: These classes in the new release are missing: WellSchematicTrack, TrackWellboreMechanicalShapeBuilder, TrackWellboreMechanicalShape. Which classes should I need to use to replace these ones ? A: These classes were a poor design choice since they tightly coupled a wellschematic shape instance with a particular view, in this case, a J/WellLog track. In the new design, you can just drop a wellschematic shape into a track, with some minor tweaking to properly scale the shape along the horizontal axis ( J/WellLog tracks have a horizontal range from 0 to 1 ). Take a look a WelllogTrackTutorial.java (in the wellschematic's tutorial directory) for an example of how to do this. The important thing to not here is that we are no longer using a specialized builder for welllog track to display a well schematic shape. Q: Methods like getName() and getDescription() for SubsurfaceSchematicShape are missing. So what should I do for these? A: In the 2.7 implementation SubsurfaceSchematicShape copied many of the properties from the corresponding data model SubsurfaceDepthIntervalObject instance that it represents. We all know duplicating data is a bad thing, so now you can just get the properties from the underlying data model object via SubSurfaceSchematicShape's getSubsurfaceObject() method. So to get the name and description of the given SubsurfaceSchematicShape instance foo, you would do the following: ```xml SubsurfaceSchematicShape foo = ..... String name = foo.getSubsurfaceObject().getName(); String desc = foo.getSubsurfaceObject().getDescription(); ```

Features Schematic Views Linear (scaled) Non-linear (compressed) Multiple completion string display Dynamically rendered, view scale independent components (e.g. Casing Shoes, Packers ) (NEW!) "Rich Text" component labeling based on HTML markup (NEW!) Shape factory plugin architecture to allow for custom wellbore shape implementations (NEW!) User definable schematic component symbols and mapping WITSML Wellbore data object support Selectable schematic view components via mouse events

Added Functionality Rich Text Labeling Pluggable shape creating architecture Dynamically rendered, view scale independent shapes

Changed Functionality com.interactive.jgeo.jwellschematic.view components have been removed and replaced with builders that create standard J/CarnacPro shapes, views, and containers.

Change Log July 2007 Major refactoring to support migration to JGeoToolkit v. 3.0 and to support dynamically rendered shapes, rich text labels, and pluggable shape implementations. Oct 2006 Refactored to cleanly decouple the data and visualization packages. Changes to com.interactive.jgeo.jwellschematic.shapes.WellboreMechanicalShape: The constructor now requires a com.interactive.jgeo.wellbore.model.Wellbore instance. Added support for selection of components via a registered java.awt.event.MouseListener ( via addMouseListener( MouseListener ) ) Changes to com.interactive.jgeo.jwellschematic.view.WellborePlot: No longer accepts a com.interactive.jgeo.wellbore.model.Wellbore or a com.interactive.jgeo.jwellschematic.shapes.WellboreMechanicalShapeBuilder to indirectly construct a WellboreMechanicalShape instance. This is now accomplished by assigning a WellboreMechanicalShape directly. 2.7.1 Release Notes J/WellSchematic was first released in 2.7.1.
