Interactive Property Map Modeling with Dynamic Azimuth Guidelines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for property mapping in conditional or unconditional simulations are limited by their inability to allow interactive drawing of azimuth guidelines, reliance on static grids, and failure to capture complex directionality, making them inflexible and time-consuming to update.
Innovation Solution
A computer-implemented method and system that enables interactive updating of property maps using user-defined well data and variogram parameters, allowing users to sketch directional patterns and add pseudo-well control points, eliminating the need for static grids and enabling rapid creation and editing of complex vector fields.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mapping systems use static grids and algorithms assuming isotropy, then the mapping process is standardized and easy to implement, but the systems cannot capture complex directionality and are inflexible to updates
Solution Approach 1:
The patent transforms static grids into dynamic azimuth guidelines that can be interactively drawn and modified by users. The vector field becomes adaptive, allowing continuous changes in directionality without requiring complete reconstruction of the underlying grid structure. This enables the system to capture complex directional patterns while maintaining ease of operation through interactive drawing tools.
Solution Approach 2:
The patent divides the continuous vector field into discrete azimuth guidelines that can be independently drawn and modified. Each guideline segment represents a directional constraint that can be adjusted separately, allowing complex directionality to be built from simple drawable elements rather than requiring complex global grid reconfiguration.
2Productivity
If mapping systems require new grids to be constructed for any changes, then data consistency is maintained, but the process becomes time-consuming and rigid
Solution Approach 1:
The system allows dynamic modification of azimuth guidelines directly on existing property maps without requiring reconstruction of underlying grids. Users can draw, move, and adjust azimuth guidelines interactively, and the property map updates in real-time to reflect these changes, dramatically reducing update time while maintaining data consistency through the simulation algorithms.
Solution Approach 2:
The patent pre-establishes the grid structure and simulation parameters once, then allows subsequent updates to be made through simple azimuth guideline drawing rather than complete re-construction. This preliminary setup enables rapid iterative updates without repeating the time-consuming grid construction process.
3Adaptability or versatility
If painting patterns are used to impose directionality, then simple directional trends can be applied, but internal changes in continuity directions local to the object cannot be accommodated
Solution Approach 1:
The patent allows different azimuth guidelines to be drawn at different locations with different orientations, enabling each local region to have its own continuity direction. Users can draw multiple azimuth guidelines with varying angles and positions to capture local variations in property continuity, rather than imposing a single uniform painting pattern across the entire map.
Solution Approach 2:
The patent allows azimuth guidelines to be drawn as curved lines rather than only straight patterns, enabling the representation of complex directional changes and curved continuity trends. This curvature capability allows local continuity directions to follow natural geological or spatial patterns rather than being constrained to rigid painting patterns.
