Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling operations face challenges in accurately steering a bottom hole assembly (BHA) in horizontal or near-horizontal wellbores, requiring high expertise and precise navigation, and struggle to adapt drill plans in real-time based on changing geological data.
Innovation Solution
A system that provides a visualization of the actual and ideal drilling paths, using data from sensors and geological surveys to adjust the drill plan intuitively, allowing operators to compare and modify the drilling path dynamically, with the aid of three-dimensional visualizations and drilling windows representing tolerances.

Engineering Contradiction Analysis
1Quantity of substance
If multiple horizontal wellbores are drilled in close proximity to access deposits, then the amount of oil or gas that can be accessed increases, but the drilling precision and tolerance requirements increase significantly
Solution Approach 1:
The system continuously monitors the actual drilling path using sensors and measurement tools, comparing real-time position data against the planned wellbore trajectory. This feedback loop enables operators to detect deviations early and make corrective steering adjustments to maintain precision within tight tolerances for multiple closely-spaced horizontal wellbores
Solution Approach 2:
The patent replaces complex manual geometric calculations and mechanical steering methods with computer-based visualization systems and electronic steering control. The system uses software to compute the ideal drilling path and provides real-time guidance, substituting human cognitive processing with automated computational algorithms that handle the complex mathematics of directional drilling
2Productivity
If the drill plan is changed in real-time based on received data to direct BHA to more productive areas, then the productivity increases, but the complexity of maneuvering the BHA according to changes increases
Solution Approach 1:
The system pre-calculates and displays the adjusted ideal drilling path before the operator executes the maneuver. By computing the optimal steering trajectory in advance and presenting it through the visualization interface, the system prepares the operator with a clear guide for the upcoming BHA maneuvers, reducing the cognitive load during actual execution
Solution Approach 2:
The visualization system acts as an intermediary between the raw drilling data and the operator's steering decisions. It translates complex geological data and drill plan modifications into an intuitive graphical representation showing the adjusted ideal path, serving as a mediator that simplifies the interaction between data analysis and physical BHA maneuvering
3Ease of operation
If traditional drill plans are used without real-time adjustments, then the operational simplicity is maintained, but the ability to adapt to changing geological conditions and maximize productivity is reduced
Solution Approach 1:
The system transforms the static, pre-planned drilling trajectory into a dynamic, adaptive path that evolves in real-time based on incoming geological data and drilling conditions. The visualization interface continuously updates the ideal drilling path, allowing the plan to adapt flexibly while maintaining operational simplicity through automated calculations and clear graphical guidance
Data Source
AI summary
Systems, devices, and methods for visualizing and steering a drilling apparatus are provided, including a drill string with a bottom hole assembly (BHA), a sensor system, and a controller operable to generate a visualization comprising an original drill plan and an adjusted ideal drilling path. The adjusted ideal drilling path may represent an ideal drilling route based on updated drilling data received by the controller such as determined parameters of geological formations. The differences between the location of the BHA and the adjusted ideal drilling path may also be visualized. This visualization may be used by an operator or the controller to steer the BHA.
