Modular Containment Mat System with Geotextile Lap Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current containment and matting systems for oil and gas drilling sites are time-consuming and costly to install, prone to tears and punctures, and lack efficient spill protection, which compromises their environmental impact reduction and operational effectiveness.
Innovation Solution
A modular containment mat system with a top and bottom surface, featuring a 100 mil well pad liner between them, interconnected through nails or bolts, and a geotextile strip with a water or chemical impervious coating to provide enhanced spill protection and traction, allowing for rapid and cost-effective installation and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If liner material is placed directly on the ground surface, then installation is simple and fast, but tears and punctures occur reducing effectiveness
Solution Approach 1:
The patent uses a matting system with a bottom surface layer that acts as a protective shell between the ground and the liner material. This flexible film structure prevents direct contact between the liner and ground surface, eliminating tears and punctures while maintaining installation efficiency. The matting system itself is a flexible film structure that can be quickly deployed.
Solution Approach 2:
The matting system is installed beforehand to create a cushioning protective layer between the ground surface and the liner material. This pre-positioned protection prevents damage to the liner before it can occur, ensuring liner integrity from the start of operations.
2Object-affected harmful factors
If traditional lining and matting systems are used, then environmental protection is provided, but installation takes significant time and cost
Solution Approach 1:
The patent combines the lining function and matting function into a single integrated matting system. The matting system includes both a bottom surface layer for ground protection and a top surface layer for spill containment, eliminating the need for separate lining and matting installations. This merger significantly reduces installation time and cost while maintaining environmental protection.
Solution Approach 2:
The matting system performs multiple functions simultaneously: it provides ground protection, spill containment, and a working surface. This multi-functional design replaces traditional multi-component systems, reducing installation complexity and time while maintaining all necessary environmental protection functions.
3Productivity
If modular mat system with liner between surfaces is used, then installation is faster and less expensive, but structural complexity increases
Solution Approach 1:
The matting system is divided into modular units with distinct top and bottom surface layers that can be manufactured separately and assembled quickly on-site. This segmentation allows for pre-fabrication and standardized installation procedures, improving installation efficiency despite the multi-layer structure. Each module is independently simple but combines to provide the full protective function.

AI summary
Improved containment mats and systems of containment mats may include multiple adjoining mats with a top surface and a bottom surface, and a liner material placed between the top and bottom surfaces. The multiple mats may provide a modular structural mat system that may be installed at a drill site, with multiple mats placed adjacent to each other with a lap joint connecting adjacent mats. A geotextile may be used to cover the lap joints and a coating applied to the geotextile. Such a system may provide containment of potential spills, a reliable working surface for drilling operations, and relatively fast and less expensive installation. The liner and geotextile may be a 100 mil well pad liner.
