Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aquifer assessment methods for agriculture are inefficient and costly, relying on trial and error drilling to find suitable groundwater, which wastes time and resources, and lack effective tools for in situ analysis of water quality and flow rate.
Innovation Solution
The development of an underground sampling tool (HTMS) that provides real-time data on aquifer quality and flow rate, equipped with gauges for pressure, temperature, conductivity, pH, and ion content, allowing for in situ analysis and sampling, and a process for its deployment and operation to determine the suitability of groundwater for irrigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trial and error drilling method is used to find suitable groundwater, then groundwater layer can be found, but drilling costs and time increase significantly
Solution Approach 1:
The patent applies preliminary action by deploying an assessment tool into the drilled hole before completing the well construction. The tool measures pressure, temperature, conductivity, and other aquifer properties in advance, allowing operators to determine groundwater suitability before investing in expensive well casing and development. This prevents wasted drilling on unsuitable formations.
Solution Approach 2:
The patent uses an intermediary assessment tool that acts as a mediator between drilling and final well completion. This tool includes sensors and measurement devices that evaluate aquifer properties without requiring full well construction, providing critical information that guides subsequent drilling decisions and reduces unnecessary drilling activities.
2Reliability
If trial and error drilling method is used to find suitable groundwater, then groundwater layer can be found, but drilling costs increase
Solution Approach 1:
The assessment tool performs preliminary evaluation of aquifer suitability by measuring pressure, temperature, conductivity, and other parameters before well completion. This early assessment prevents wasted drilling costs on unsuitable formations and reduces the need for repeated drilling attempts.
Solution Approach 2:
The patent implements feedback by using measurement data from the assessment tool to guide drilling decisions. The tool provides real-time information on aquifer properties, allowing operators to adjust drilling strategies, avoid unsuitable formations, and optimize well placement, thereby reducing overall drilling costs.
3Measurement precision
If comprehensive water quality analysis is performed after drilling, then accurate quality data is obtained, but time and cost are wasted if water is unsuitable
Solution Approach 1:
The patent performs preliminary water quality assessment by measuring conductivity, pressure, temperature, and other parameters during the drilling process using the assessment tool. This early evaluation identifies unsuitable aquifers before costly well completion and extensive laboratory analysis, saving significant time and resources.
Solution Approach 2:
The patent replaces traditional mechanical sampling and laboratory analysis with in-situ electronic sensing and measurement. The assessment tool uses electrical conductivity sensors, pressure transducers, and temperature probes to evaluate water quality parameters directly in the aquifer, providing rapid results without requiring physical water samples or laboratory processing.
4Reliability
If well depth is increased to find suitable groundwater, then better water quality may be found, but drilling equipment cost and operational complexity increase
Solution Approach 1:
The assessment tool provides preliminary evaluation of aquifer suitability at different depths during the drilling process. By measuring pressure, temperature, conductivity, and other parameters in real-time, the tool identifies suitable groundwater zones without requiring excessive drilling depth, thereby avoiding the need for increasingly complex and expensive drilling equipment.
