Definitions

  • the present invention relates to a method for visualization and analysis of volume data, particularly related to petroleum exploration and production, including means for storing, processing and visualization of the data.
  • the work processes mentioned above all include analysis of large 3-dimensional (3D) datasets.
  • the analysis is normally done by experts working on graphical work stations.
  • the graphical workstations suffer from several weaknesses :
  • the screen size limits the amount of information that can be presented.
  • a graphical workstation is designed for one single user.
  • VR Virtual Reality
  • the invention addresses one important challenge by introducing VR in E&P, that is to find effective ways for visualising large amounts of volume data in real time
  • a method is provided by which it is possible to select and process a data set by forming a Real time Volume Window (RVW). More precisely the invention is characterized in that, within the total volume of three dimentional data, one or more limited volume windows are created which can be interactively and in real time moved around in the entire data volume and viewed from different positions and at different angels and whereby, by color and opacity manipulation, the data inside the volume windows are made transparent, thus allowing for a realistic real time visualization of selected target positions of the data sets.
  • RVW Real time Volume Window
  • RVW is an alternative to the methods listed above.
  • semi-transparent data can be shown within a 3-dimensional window (volume window) with dimensions defined by the user.
  • volume window can be moved around interactively in the total volume dataset in real time.
  • RVW is a flexible method which is assumed to be of significant importance in future virtual reality systems within the oil and gas industry. Simply by adjusting the window parameters, the concept allows for adaption to any size of seismic datasets or machine computing power, so that real time responses are achieved.
  • RVW right atrial pressure
  • Several important applications of RVW can be found within the field of oil and gas exploitation, such as visualization of seismic data, interactive region growing of seismic data and interactive well planning. RVW is implemented as a plug-in in an open system without the loss of performance.
  • RVW has generalized window parameters, i.e. the size and resolution of the volume windows, together with selection of dataset and colour parameters can be adjusted interactively by the user.
  • RVW has generalized window orientation. It may either have a strictly view dependent (VD) orientation, or it may have a spatial mouse (SM) dependent orientation. In both cases the RVW is drawn using texture based volume rendering with planes perpendicular to the viewing direction.
  • RVW's can be used simultaneously in a virtual reality system, with different datasets in each volume window.
  • Fig. 1 shows the main componets of the system architecture by which the method is performed
  • Fig. 2 shows a flowchart for real time volume windows according to the invention
  • Fig. 3 shows a flowchart for interactive well planning based on RVW
  • Fig. 4 is an image of a geological formation depicting a volume window in centre.
  • Fig. 1 shows, as stated above, the main componets of the system architecture for the method according to the invention.
  • the system operated by the end users (geoprofessionals), is provided through algorithms, to preprocess the petroleum input data from a storing medium into formats or datastructures (VR-data) suited for real time rendering.
  • the preprocessing may include: - Generation of multiresolution geometric models through spatial subdivision, simplification and/or aggregation.
  • the system kernel manages rendering and state changes in different VR-tools, while the general user interface (GUI) event loop submits messages to the command interpreter in the VR-tools (indicated by the black pattern in Fig. 1 ).
  • GUI general user interface
  • the different VR-tools represents a set of related analysis algorithms that operate on specific VR-data, and an editor for parameters associated with these algorithms. In this context, analysis refers to both rendering and interactive modelling or interpretation af data. Examples of different tools may be "path tool” to show well paths and reveal well log information; “slice tool” to show opaque colored slices and "volume window tool” to show and open one or several windows, drag window etc.
  • RVWj An overview of the RVW method is given in the flowchart in Fig.2. A description of each individual process in the flowchart is given below. The processes are referred to as RVWj, where j is the number indicated in each box in the flowchart.
  • RVW visualizes volume data by drawing a set of slices or planes through the volume.
  • the planes always have an orientation perpendicular to the viewing direction.
  • the planes can be made transparent, thus one can look into the volume and not only on the plane closest to the users eyes.
  • Data are mapped to each plane using texture mapping.
  • the first method is software based and the textures are calculated by slicing the volume data in software.
  • the second method is to load the entire data set into texture memory of the computer, and leave the texture mapping to the rendering hardware.
  • the RVW involves the use of several different coordinate systems as desribed below.
  • the system calculates and stores the matrixes needed for transforming data between these coordinate system.
  • Data set coordinates Specific coordinate system for each idividual dataset. For seismic datasets, these coordinates will normally be defined in terms of inline number, crossline number and timeslice number in the x, y, and z direction respectively.
  • Texture coordinates The coordinate system for the texture memory in the computer. Describes where the data is stored in computer texture memory.
  • Device coordinates The coordinate system for the display device where the data is finally visualized.
  • the device coordinates will range from 0 to the size of the screen in the x and y direction respectively.
  • RVW1 A computer program reads 3D seismic datasets into computer memory.
  • RVW2 The computer program initialises a list of volume windows to be maintained and resets the counter for the number of volume windows to be generated.
  • RVW3 The user of the RVW system defines following parameters :
  • RVW4 The user of the RVW system defines an initial position of the volume window by use of a pointing device such as a spatial mouse.
  • the computer program then reads the position and creates the volume window at that position.
  • RVW5 The computer program inserts relevant information about the volume window in a list of volume windows to be maintained by the computer.
  • RVW6 The computer program checks if the user wants to create more windows by checking the status of the users spatial mouse.
  • RVW7 The computer program receives the users eye position and viewing direction from the tracking system.The information comes from a sensor near the eyes of the user. This sensor is connected to the tracking system, which continuously delivers updated viewing parameters to the application. These data are defined in device coordinates.
  • RVW8 The computer program initializes the loop that draws all volume windows in the window list (see RVW5).
  • the computer program receives any changes in the position and orientation of the volume window.
  • the position can be continuously changed using a spatial mouse.
  • the orientation of the volume window may be independent of the viewing direction. In this case, the orientation can be changed by using the spatial mouse (SM orientation).
  • the window can also be oriented in a view dependent direction (VD orientation).
  • the orientation is then calculated so that the window is perpendicular to the viewing direction, see RVW7 above. In both cases, the planes inside the volume window are oriented perpendicular to the viewing direction. See Fig. 1.
  • RVW10 The computer program register changes in the parameters for the volume window, see RVW3. Some parameters can be changed based on the viewing direction and by using the spatial mouse, see RVW9. Additional parameters can be changed using a menu system or voice input.
  • RVW11 Every time a change occurs in position, viewing direction or other viewing parameters for a volume window, one or more of the following is done:
  • the computer program calculates the position and orientation of the planes in the volume window (perpendicular to viewing vector). For VD orientation, the volume window itself is also oriented perpendicular to the viewing vector.
  • the computer program calculates the position for lower left corner in addition to two vectors describing the orientation and size of the plane.
  • the point and vectors are input to the computer program that calculates the texture of the plane from the volume data.
  • the method used is trilinear interpolation, and it calculates a 2D slice through the data given by the input plane specification.
  • point 3 is automatically done by the computer hardware.
  • RVW12 Drawing of the volume windows includes the following steps carried out by the computer program:
  • RVW13 The computer program checks if the user wants to delete the window by checking the status of the spatial mouse.
  • RVW15 The computer program deletes the window from the list of windows to be maintained.
  • RVW16 The computer program selects the next window to be drawn from the list of windows to be maintained.
  • RVW17 The computer program checks if the end of the list of volume windows to be maintained is reached.
  • RVW18 The computer program checks if the application is to be finished by checking the status of the spatial mouse. If not, control is given to RVW6.
  • 3D seismic data is traditionally done on graphical workstations, either by looking at 2D slices cut through the 3D data volume or by visualizing a complete 3D data cube.
  • the RVW comprises a method for viewing 3D seismic data in a virtual environment where both the 3D perspective and real time response times are obtained.
  • the size of the input 3D dataset is limited only by the amount of RAM in the computer.
  • a volume window By placing a volume window inside the 3D dataset, a limited part of the seismic data can be viewed in full resolution. Different parts of the data can be viewed by interactively moving the volume window by use of a spatial mouse. In this manner, it is possible to get better understanding of geological features contained in the 3D seismic data.
  • Such features may consist of everything from large scale structures like geological horizons and faults, via medium scale events like channel structures and sand lenses, to small scale internal reflection patterns.
  • the RVW can be used as a tool for volume detection by means of region growing.
  • the volume window limits the area in which the region growing is performed.
  • the position, size and orientation is controlled by using the spatial mouse (SM orientation).
  • a seed point for the region growing is defined and placed within the window using the spatial mouse. Threshould values for the region growing are also defined.
  • the user controls the region growing by using buttons on the spacial mouse, a menu system or voice input.
  • the data points detected by the region growing process are visible instantaneously because the algorithm directly updates the data set that is loaded into texture memory of the computer.
  • the colour table By altering the colour table, one can choose to see only the detected data points, or the detected data points in combination with the original data set.
  • One specific colour in the colour table is allocated to the detected data points.
  • the volume window can be moved by the spatial mouse and the region growing can be continued.
  • the new seed point will then be the last data point that was detected in the previous position of the volume window.
  • the detected data points are buffered to support undo and redo functionality.
  • a method for interactive well planning in a virtual environment is sketched in the flowchart in Fig.3.
  • the method can be used either to visualize existing well paths and log information or to design paths for new wells to be drilled.
  • a well path is defined by a set of node points connected by a spline curve.
  • a new well path is designed by pointing and clicking a spatial mouse at selected positions in 3D space.
  • a new node point will be generated for each click..
  • the well path will be represented by a spline curve connecting the node points.
  • the spline curve will be drawn in real time.
  • An existing node point can be changed simply by grabbing it and move it to the desired posisiton with the spatial mouse. Similarly, an existing node point can be deleted.
  • the spline curve will be updated in real time.
  • Information from seismic data is neccessary in order to position a new well at the correct location in space.
  • This can be achieved by combining the RVW with the interactive well planning process in the following manner: One or more volume windows are placed in the area where the well is being planned. The positions of the volume windows are fine tuned until the seismic data inside the window clearly reveals the drilling target. The target feature can be made more clear by changing the opacity curve for the window, e.g by making all datapoints in the volume window transparent exept the ones representing the target. Node points for the new well path can now be placed in the middle of the target by pointing and clicking the spatial mouse inside the volume window as described above. If the planned well path extends outside the volume window, the volume window can be slightly moved and the process repeated.
  • An example of well planning with RVW is given in Fig. 4.

Abstract

La présente invention concerne un procédé de visualisation et d'analyse de données de volume, particulièrement lié à l'exploration pétrolière et la planification de la production, et notamment des dispositifs de stockage, de traitement et de visualisation de données. Par ailleurs, une ou plusieurs fenêtres de volume sont créées dans le volume global de données tridimensionnelles, en l'occurrence celui des données sismiques, ces fenêtres pouvant être déplacées de manière interactive et en temps réel dans la totalité du volume de données, et visualisées depuis des positions et des angles variés. Grâce à des modifications en terme de couleur et d'opacité, les données contenues dans les fenêtres de volume sont rendues transparentes, permettant ainsi une visualisation fidèle en temps réel des positions cibles sélectionnées dans les ensembles de données.
