Self-Loading Waste Capsule Deployment in Viscous Wellbores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for disposing of waste in deep underground formations are expensive, time-consuming, and pose safety risks due to the need for extensive drilling operations and manual handling of waste capsules, which requires significant resources and increases the risk of accidents.
Innovation Solution
The implementation of a self-loading system where waste capsules are dropped into wellbores filled with a fluid of controlled viscosity, allowing them to reach a terminal velocity that enables safe and efficient deployment without external force, reducing the need for expensive equipment and minimizing human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling operations and manual handling of waste capsules are used, then waste can be disposed of in deep underground formations, but operational costs increase and safety risks arise
Solution Approach 1:
The waste capsule automatically enters the wellbore under its own weight without requiring external handling equipment. The capsule self-propels down the wellbore using gravity, eliminating the need for complex drilling equipment and manual handling operations, thereby reducing both costs and safety risks.
Solution Approach 2:
The patent replaces complex mechanical drilling and handling systems with a simple gravity-based deployment mechanism. Instead of using drilling rigs and manual operations to place waste capsules, the system allows capsules to freely fall under gravity into the wellbore, substituting complex mechanical systems with a natural physical force.
2Productivity
If extensive drilling operations are conducted, then wellbores can be created for waste disposal, but time consumption increases
Solution Approach 1:
The wellbore is pre-prepared with appropriate dimensions and conditions before waste capsule deployment. The wellbore is drilled in advance and left ready to receive capsules, eliminating the need for time-consuming operations during the actual waste disposal process. Capsules can be rapidly deployed into the pre-prepared wellbore structure.
3Ease of operation
If manual handling of waste capsules is performed, then capsules can be placed in wellbores, but resource requirements increase
Solution Approach 1:
The waste capsule performs the placement operation itself by utilizing its own weight to enter the wellbore. No external handling equipment or manual labor is required - the capsule self-propels down the wellbore under gravity, eliminating resource requirements for handling operations while maintaining operational simplicity.

AI summary
Self-loading systems and methods for disposal of waste materials in a deep underground formation may include at least one wellbore that runs from the Earth's surface to the deep underground formations, wellbore viscous fluid within that at least one wellbore, and at least one waste capsule, wherein the at least one waste capsules houses some waste and is configured to fall within both the at least one wellbore and the wellbore viscous fluid. The systems and methods may also include at least one human-made cavern located in the deep underground formation and connected to the at least one wellbore, wherein the at least one human-made cavern may be configured to receive the at least one waste capsule. The systems and methods may also include a counter for counting waste capsules and/or a robot for dropping waste capsules into a wellhead leading to the at least one wellbore.
