Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional telemetry and data presentation methods struggle to effectively convey volumetric logging data, particularly in hostile drilling environments, where measurements extend further into formations surrounding the borehole, limiting the ability to provide meaningful insights to drillers and users.
Innovation Solution
The development of borehole data presentation systems and methods that facilitate communication of volumetric logging data to a surface processing system, employing tailored telemetry streams and advanced visualization techniques such as three-dimensional displays, holographic, and stereoscopic technologies to represent formation properties like resistivity, density, and porosity, allowing for cylindrical cross-plots and user-controlled viewing positions.

Engineering Contradiction Analysis
1Loss of information
If traditional two-dimensional logging displays are used, then the system is simple to operate and understand, but the system cannot effectively convey volumetric logging data extending further into formations
Solution Approach 1:
The patent transitions from traditional two-dimensional log displays to three-dimensional visualizations that represent formation properties as a function of depth, azimuth, and radial distance. This dimensional expansion allows volumetric logging data to be effectively conveyed while maintaining operational simplicity through intuitive graphical interfaces.
Solution Approach 2:
The system integrates multiple visualization modes (2D logs, 3D volumetric displays, cross-sectional views) within a single data presentation platform. This multi-functionality allows the system to adapt to different user needs and data types while maintaining a unified operational interface, resolving the contradiction between information completeness and system complexity.
2Loss of information
If advanced three-dimensional visualization techniques are employed, then comprehensive volumetric data can be represented, but the system complexity increases
Solution Approach 1:
The patent segments volumetric logging data into discrete radial bins at multiple depths and azimuths, allowing complex three-dimensional formation characteristics to be broken down into manageable computational units. This segmentation enables efficient processing and display of comprehensive volumetric data without overwhelming system complexity.
Solution Approach 2:
The system employs an intermediary processing layer that transforms raw volumetric logging data into standardized three-dimensional visualizations. This intermediary layer handles the complexity of data processing, coordinate transformations, and rendering, while presenting simplified, intuitive visual outputs to users, thereby masking system complexity.
3Loss of information
If telemetry streams are tailored for high-bandwidth three-dimensional data transmission, then volumetric data can be communicated effectively, but the system becomes less adaptable to bandwidth-constrained environments
Solution Approach 1:
The patent implements dynamic telemetry stream configuration that adapts to available bandwidth conditions. The system can adjust the resolution, radial bin density, and data transmission rate based on real-time bandwidth availability, allowing effective volumetric data communication in both high-bandwidth and bandwidth-constrained environments without sacrificing system versatility.
Solution Approach 2:
The system dynamically changes telemetry parameters such as radial resolution, azimuthal sampling rate, and data compression levels based on bandwidth conditions. This parameter adaptation allows the system to maintain effective volumetric data transmission across varying bandwidth environments, resolving the contradiction between data fidelity and environmental adaptability.

AI summary
Borehole data presentation systems and methods that facilitate communication of volumetric logging data to a surface processing system for presentation to a driller or other user interested in visualizing the formations surrounding a borehole. The disclosed systems optionally tailor the telemetry stream to match the chosen display technique, thereby maximizing the logging system utility for the driller. Variable opacity of certain data regions or certain data discontinuities greatly facilitates data comprehension, particularly when true three-dimensional display technologies are employed. Holographic or stereoscopic display technologies may be employed to show the three-dimensional dependence of measured formation properties such as resistivity, density, and porosity. Alternatively, the radial axis can be used to represent a formation parameter value, thereby enabling cylindrical cross-plots of multiple measurements. The user can control viewing position and orientation to more fully explore the three dimensional representation.
