Wellbore Path Visualization for Collision Avoidance Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for planning wellbores are ineffective in identifying pre-existing wellbore trajectories, leading to potential collisions and inefficient resource use, as they rely on costly and inaccurate external databases for collision avoidance.
Innovation Solution
A system and method that utilize an internal database to automatically generate a list of avoidance components, including pre-existing wellbores, endangered zones, and other restrictions, to visualize and adjust drilling paths, reducing the risk of collisions and improving planning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional systems use external databases to identify avoidance components, then collision avoidance information can be obtained, but the process is costly, inefficient, and yields incomplete data with inaccuracies
Solution Approach 1:
The system creates a digital copy of avoidance component data by generating three-dimensional representations of wellbores and geological features from existing well log data and geological models. These digital copies enable accurate collision detection without requiring access to external databases, thereby improving both accuracy and efficiency simultaneously
2Reliability
If radial scans are performed to detect avoidance components, then some collision risks can be identified, but the system cannot completely identify trajectories of pre-existing wellbores
Solution Approach 1:
The system transitions from two-dimensional radial scan analysis to three-dimensional wellbore trajectory reconstruction. By creating 3D representations of wellbores and integrating them with geological models, the system achieves complete trajectory identification and reliable collision detection that was impossible with conventional radial scan methods
3Loss of information
If individual licenses and subscription fees are paid to search regional databases, then avoidance component data can be obtained, but the process is costly and yields incomplete data
Solution Approach 1:
The system performs self-service by automatically generating avoidance component information from existing well log data and geological models already available in the system. This eliminates the need to purchase data from external databases, reducing costs to zero while providing complete and accurate avoidance component identification through internal data processing

AI summary
A system and method are provided to detect and avoid wellbore collision. The method may include receiving, by a processor, a path of a proposed wellbore. The processor then receives a boundary surrounding the path of the proposed wellbore. The processor then generates, automatically, a list of avoidance components within the boundary using an internal database. The proposed wellbore and avoidance components in the list are then displayed by a visualization system.
