Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing downhole tool control systems for piping assemblies are inefficient and unreliable, particularly in deep cased wells, due to excessive length and complexity, which increases operating times and reduces reliability, and are not suitable for open hole wells without complicated pressure fluctuations.
Innovation Solution
A networkable control system using addressed datagrams that transmit and receive information through transmitters, receivers, and controllers, allowing for selective communication and logical operations on controllable devices within piping assemblies, including valves, switches, and pumps, using a variety of working mediums such as mechanical, hydraulic, or electromagnetic, enabling efficient control and measurement without lengthy pressure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard pressure controlled tools are used in deep cased wells, then the operating pressure would exceed the burst rating of the casing, but the patent enables operation in deep cased wells by using addressed datagrams to control devices without requiring high pressure signals
Solution Approach 1:
The patent replaces the traditional mechanical pressure-controlled system with an electromagnetic communication system using addressed datagrams. Instead of using high-pressure signals to control downhole devices, the system transmits control information through electromagnetic fields via addressed datagrams that can be received and acted upon by controllers at various depths without requiring excessive operating pressure that would risk casing failure
Solution Approach 2:
The patent changes the control parameter from pressure-based to data-based control. By using addressed datagrams containing control instructions, the system eliminates the need for high-pressure signals while maintaining the ability to control downhole devices, thus enabling operation in deep cased wells where pressure would otherwise exceed safety limits
2Productivity
If older pressure controlled valve devices are used, then they require lengthy operating times due to complicated pressure changes, but the patent reduces operating time by using addressed datagrams for direct control
Solution Approach 1:
The patent replaces the complex mechanical pressure cycling process with direct electromagnetic control through addressed datagrams. Controllers receive datagrams containing specific control instructions and can actuate valves and other devices directly without requiring lengthy sequences of pressure changes, significantly reducing the time needed to cycle devices from closed to opened positions and back
Solution Approach 2:
The addressed datagrams contain pre-programmed control instructions that enable controllers to execute device operations directly without requiring complex real-time pressure management. This preliminary encoding of control logic in the datagrams allows for faster response and reduced operating time compared to traditional pressure-controlled systems
3Adaptability or versatility
If combination of tester, sampler and circulating valves are used, then the dimensional length becomes excessive exceeding 200-300 feet, but the patent reduces the length by using compact addressed datagram controlled devices
Solution Approach 1:
The patent implements multi-functional downhole devices that can perform multiple service operations (testing, sampling, circulating) within a single compact tool assembly. The addressed datagram control system enables a single controller to manage multiple functions and devices, eliminating the need for separate long tool strings for each function and reducing the overall dimensional length while maintaining versatility
Solution Approach 2:
The patent merges multiple service functions (tester, sampler, circulating valves) into a single integrated tool assembly controlled by addressed datagrams. This consolidation reduces the total length from excessive 200-300 feet to a more manageable size while maintaining the ability to perform multiple service operations during single or multiple trips into the wellbore
4Adaptability or versatility
If complicated valve systems are used to perform multiple operations, then reliability decreases and chances of mishaps increase, but the patent increases reliability by using simple addressed datagram controlled devices
Solution Approach 1:
The patent segments the control system into independent addressed datagram receivers and controllers that can operate autonomously based on received instructions. This segmentation eliminates complex interconnections between multiple valve systems, reducing the chances of mishaps and improving reliability while still enabling multiple service operations through coordinated control of simpler individual components
Solution Approach 2:
The patent replaces complicated mechanical valve systems with simpler electromechanical devices controlled by addressed datagrams. This substitution reduces mechanical complexity and the number of moving parts that could fail, thereby increasing reliability while maintaining the capability to perform multiple service operations through intelligent control

AI summary
A control system with probes for generating and utilizing at least one or more addressed datagrams that communicate information to and from devices along piping assemblies comprising; one or more transmitters, one or more receivers, and one or more controllers, wherein the transmitters transmit information via one or more addressed datagrams encoded within a working medium to one or more receivers among the piping assemblies, is described. Transmitters convert datagrams into signals that are transmitted within the working medium and the receivers receive signals from the transmitters and also convert signals from the working medium which is converted back into datagrams. The controllers receive and decode the datagrams so that the controllers selectively communicate and perform logical operations on piping assembly devices according to directions received from the addressed datagrams. The entire control system can function as a network of controllers, receivers, transmitters, and/or transponders as required by one or more users.
