Systems and methods for speed-adjustable model navigation are provided. In aspects, a model platform includes a model engine and a speed tool that operates with the model engine to generate a graphical view of a geological model. Various features of the geological object may be encoded or reflected in the geological model, including the composition, pressure, temperate, structure, fracture lines, and other aspects of a hydrocarbon deposit, cavity, or other geological structure. The user may operate the speed tool to examine the histogram of color or intensity of the pixels or voxels of regions of the model view, and set a speed curve to control how quickly or slowly a cursor or other control may move through or traverse a region, based on the color, intensity, or other value. Regions of interest may be explored more efficiently and accurately.

Systems and methods for speed-adjustable model navigation

The present invention relates to a method of displaying a dynamic 2D annotation associated with an object displayed in a 3D scene. The method includes providing a computer system that includes a display device; establishing a view location and direction; orienting the dynamic 2D annotation substantially perpendicular to the view direction; orienting the dynamic 2D annotation substantially horizontal relative to the 3D scene; positioning the dynamic 2D annotation relative to an attachment point on or near the object; extending an attachment handle between the dynamic 2D annotation and the attachment point; and displaying the dynamic 2D annotation and the attachment handle in the 3D scene on the display device.

Presenting textual and graphic information to annotate objects displayed by 3D visualization software

A method for visualizing oilfield data of an oilfield operation involves obtaining real-time data generated from a borehole, generating and updating a current position object, and displaying and annotating a representation of a first geology, geophysics, drilling, and production object in a display based on the oilfield data using a two dimensional (2D) callout having an attachment handle for adjusting the 2D callout according the updated location in an animation sequence in real-time responsive to updating the current position.

Visualization techniques for oilfield operations

The invention relates to a method for performing a drilling operation at a wellsite having a drilling rig configured to advance a drilling tool into a subsurface. The method steps include obtaining a well trajectory associated with a first volume, obtaining information related to a first subsurface entity associated with a second volume, using a three-dimensional relational comparison to determine that the first volume intersects the second volume to define a first intersection information, updating the well trajectory, based on the first intersection information, to obtain an updated well trajectory, and advancing the drilling tool into the subsurface based on the updated well trajectory.

A method of highlighting a selected object in a 3D scene comprises: executing an off screen rendering software and, responsive thereto, generating a texture image containing an image of the visible parts of a selected object over a background color, and, in response to said texture image, executing an on screen rendering software in combination with a fragment shader software thereby drawing a silhouette of the selected object.

Method for locating underground deposits of hydrocarbon including a method for highlighting an object in a three dimensional scene

The invention relates to a method of performing a drilling operation for an oilfield. The method includes collecting oilfield data, a portion of the oilfield data being real-time drilling data generated from the oilfield during drilling, defining a number of oilfield events based on the oilfield data, selectively displaying the number of oilfield events in proximity of a wellbore image of a display, updating the display of the number of oilfield events during drilling based on the real-time drilling data.

System and method for performing oilfield drilling operations using visualization techniques

A volume rendering process is disclosed for improving the visual quality of images produced by rendering and displaying volumetric data in voxel format for the display of three-dimensional (3D) data on a two-dimensional (2D) display with shading and opacity to control the realistic display of images rendered from the voxels. The process includes partitioning the plurality of voxels among a plurality of slices with each slice corresponding to a respective region of the volume. Each voxel includes an opacity value adjusted by applying an opacity curve to the value. The opacity value of each voxel in each cell in the volume is converted into a new visual opacity value that is used to calculate a new visual opacity gradient for only one voxel in the center of each cell. The visual opacity gradient is used to calculate the shading, used to modify the color of individual voxels based on the orientation of opacity isosurfaces passing through each voxel in the volume, in order to create a high quality, realistic image.
