Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sequential well planning workflows are used with traditional 2D maps and 3D visualization tools, then individual functions (target selection, trajectory design, hazard analysis) can be performed, but the process becomes time-consuming and inefficient due to lack of dynamic data integration and multiple iterations

Engineering Contradiction:
Improvewell path planning efficiencyVSAvoidtime for iterations and evaluations
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple sequential functions (target selection, trajectory design, hazard analysis, rock property evaluation) into a single integrated 3D workflow environment. Geoscientists and drilling engineers can simultaneously access and evaluate all relevant data layers (seismic data, well logs, rock properties, hazards) within one unified 3D visualization framework, eliminating the need to switch between multiple tools and perform repeated data transfers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent transitions from traditional 2D map-based target selection to immersive 3D visualization of the subsurface environment. This dimensional upgrade allows users to interactively explore reservoir geometry, trajectory options, and hazard locations in three-dimensional space, enabling more efficient evaluation of multiple well path scenarios and reducing iterative revisions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If detailed rock and fluid property analyses are performed for each well trajectory, then accurate engineering decisions can be made, but the complexity of obtaining and integrating data from multiple sources increases significantly

Engineering Contradiction:
Improveaccuracy of well design analysisVSAvoiddata integration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal 3D data framework that serves multiple functions simultaneously: visualizing reservoir geometry, displaying rock and fluid properties, identifying hazards, evaluating trajectory options, and performing engineering analyses. This multi-functional platform eliminates the need for separate data integration processes for each analysis type, as all data layers are pre-integrated and accessible within the same 3D environment.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If multiple well scenarios are evaluated with comprehensive data integration, then optimal well trajectories can be identified, but the interactivity and collaboration between geoscientists and engineers are limited in traditional workflows

Engineering Contradiction:
Improveability to evaluate multiple scenariosVSAvoidcross-functional collaboration ease
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a shared 3D visualization environment as an intermediary platform between geoscientists and drilling engineers. This mediator allows both disciplines to interact with the same data and models simultaneously, facilitating real-time collaboration and joint decision-making. Users can define screening constraints, evaluate trajectories, and assess hazards within the same interactive framework, eliminating silos and improving communication.

Inventive Principle:
Principle #24Intermediary (Mediator)
