Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional jetting tools are used, then the equipment can be cleaned, but the desired fluid spray pattern cannot be provided and multiple pipe trips are required
Solution Approach 1:
The jetting tool is divided into modular components including a body, multiple nozzle assemblies that can be independently positioned, and removable nozzle elements. This segmentation allows the tool to be reconfigured for different cleaning scenarios without requiring multiple pipe trips, as each module can be adjusted to address specific cleaning needs.
Solution Approach 2:
The nozzle assemblies are designed to be movable and adjustable along the tool body, allowing dynamic repositioning to optimize fluid spray patterns for different equipment geometries. This dynamic capability enables a single tool configuration to handle multiple cleaning scenarios that previously required multiple fixed tools and pipe trips.
2Adaptability or versatility
If conventional jetting tools are used, then cleaning can be performed, but the tools cannot be quickly reconfigured
Solution Approach 1:
The tool employs segmented nozzle assemblies that can be independently removed and replaced. Each nozzle assembly is a discrete unit that can be quickly swapped without affecting other components, enabling rapid reconfiguration of the tool for different applications without complex disassembly procedures.
Solution Approach 2:
The tool body is designed as a universal platform that can accommodate multiple types of nozzle assemblies with different spray patterns, angles, and flow rates. This multi-functionality allows a single tool to perform various cleaning tasks by simply changing the nozzle assemblies, eliminating the need for multiple specialized tools.
3Reliability
If conventional jetting tools are used, then some cleaning is achieved, but thorough cleaning of all equipment surfaces cannot be ensured
Solution Approach 1:
Different nozzle assemblies are designed with specific spray patterns, angles, and pressure characteristics optimized for different equipment surfaces and contamination types. By selecting and positioning the appropriate nozzle assembly for each specific cleaning location, the tool achieves thorough cleaning of all equipment surfaces including internal cavities and crevasses in a single operation.
Solution Approach 2:
The tool incorporates nozzles that can direct fluid spray in multiple dimensions including radial, axial, and tangential directions. This multi-directional spray capability allows the tool to access and clean complex equipment geometries such as internal cavities and crevasses that single-direction conventional tools cannot reach, ensuring thorough cleaning without additional pipe trips.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cleaning efficiency, reduces rig time and costs, and improves health, safety, and environmental performance by allowing for flexible and effective fluid jetting operations with customizable nozzle sizes and configurations.
Implementation Method 1
Jetting tools can be used to direct pressurized fluid at internal surfaces of said equipment in order to remove or clean such accumulations from said surfaces
Implementation Method 2
Pressurized fluid is then pumped through the tubular work string and jetting tool at the inner surface(s) of such equipment. The pressurized fluid acts to loosen and clean any accumulated solids

AI summary
A multi-functional jetting tool can be installed within a tubular work string, or attached to the distal or leading end of the tubular work string, in order to facilitate improved cleaning of downhole and/or subsea equipment—and particularly equipment with internal recesses, cavities or crevasses. A bull nose cap member, which can be constructed of plastic or other non-abrasive material, can be attached when the jetting tool is run on the distal end of a tubular work string. Fluid jetting ports can be selectively equipped with standard-sized or adjustable nozzles, thereby permitting customized fluid jet flow pattern from the jetting tool along the tool body in multiple directions for desired applications.
