Single Bore Well Access via Chamber Junctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for performing operations on multiple wells require numerous bores and conduits, leading to high costs and inefficiencies, especially in harsh environments, and are limited by the need for extensive above-ground equipment and restricted passage diameters, which hinder access to deep strata.
Innovation Solution
The system employs a single main bore with chamber junctions and a bore selection tool to enable communication with multiple wells through a substantially continuous diameter passage, allowing for batch drilling and completion operations without the need for extensive above-ground equipment, using a chamber junction with multiple orifices and a bore selection tool to selectively access and operate individual wells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods are used to perform operations on multiple wells, then each well can be accessed independently, but the number of bores and conduits increases significantly, leading to high costs and extensive above-ground equipment
Solution Approach 1:
The patent combines multiple well access functions into a single bore structure. A single bore contains multiple conduits that can be selectively accessed through a bore selection tool, merging what would traditionally require multiple separate bore systems into one integrated structure, thereby reducing above-ground equipment while maintaining the ability to access multiple wells independently
Solution Approach 2:
The single bore system is designed to perform multiple functions by accommodating different conduits for different wells within the same bore structure. The bore selection tool enables this universal access mechanism, allowing one bore to serve multiple wells that would traditionally require separate access points
2Ease of operation
If conventional above-ground equipment is used for each well, then each well can be operated independently, but the cost and environmental impact increase significantly
Solution Approach 1:
Multiple well operations are merged into a single bore structure, reducing the number of separate above-ground equipment installations needed. This consolidation maintains independent operational capability through the bore selection tool while minimizing the physical footprint and environmental impact of surface equipment
3Device complexity
If a single bore is used to access multiple wells, then costs and equipment are reduced, but the passage diameter is restricted, hindering access to deep strata
Solution Approach 1:
The single bore is segmented into multiple independent conduits, each capable of accommodating tools and equipment for specific well operations. This segmentation allows each conduit to be optimized for its specific function while maintaining access to deep strata, overcoming the diameter restriction issue by dividing the passage into functional segments rather than requiring one large undivided passage

AI summary
Systems and methods usable to operate on a plurality of wells through a single main bore are disclosed herein. One or more chamber junctions are provided in fluid communication with one or more conduits within the single main bore. Each chamber junction includes a first orifice communicating with the surface through the main bore, and one or more additional orifices in fluid communication with individual wells of the plurality of wells. Through the chamber junctions, each of the wells can be individually or simultaneously accessed. A bore selection tool having an upper opening and at least one lower opening can be inserted into the chamber junction such that the one or more lower openings align with orifices in the chamber junction, enabling selected individual or multiple wells to be accessed through the bore selection tool while other wells are isolated from the chamber junction.
