Rig mat sprayed with polyurea systems

Abstract

A containment mat generally including matting tiles and a polyuria / polyurethane coating. Matting tiles are preferably formed from composite recycled rubber and are arranged in a first layer and a second layer with overlapping edges forming a shiplap design. The polyuria / polyurethane coating is sprayed on the seams between matting tiles creating a solid containment mat. A rig mat system may include a rig mat and a sealed leak-proof containment berm made from geo-fabric and foam blocks that are encapsulated in the geo-fabric and sprayed with the polyuria / polyurethane coating. The area between the berm and the matting tiles creates a trough for containing liquids.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit under 35 U.S.C. §119(e) of the earlier filing date of U.S. Provisional Patent Application No. 61 / 755,591 filed on Jan. 23, 2013, which is hereby incorporated by reference.FIELD OF THE INVENTION[0002]This application discloses an invention which is related, generally and in various embodiments, to solid containment for the oil and gas industry and other areas.BACKGROUND OF THE INVENTION[0003]Fracking is a method of extracting natural gas that is trapped in layers of shale beneath the Earth's surface. The process involves drilling into the shale layers and pumping pressurized fluid to recover natural gas. The environment is exposed to harmful contaminates during the drilling and recovery process of natural gas and oil products.[0004]Typical drilling sites are constructed and developed with heavy earth moving machinery until the best substructure is created to stabilize the ground that the drilling rig is place...

AI Technical Summary

Benefits of technology

The patent describes a system for a rig mat that is used in the oil and gas industry to create a safe and solid surface for drilling and hydraulic fracking. The rig mat is made from recycled rubber tiles and a polyurea coating that is sprayed on the seams between the tiles. The polyurea coating is a non-breachable seal that contains liquids that may be harmful to the environment. The technical effect of this invention is to provide a more durable and reliable containment solution for drilling and hydraulic fracking sites, as well as other areas such as farming, that can withstand heavy equipment and protect the environment from harm.

Problems solved by technology

The environment is exposed to harmful contaminates during the drilling and recovery process of natural gas and oil products.

The weight of these current mats threatens the integrity of the plastic liner during the installation process.

Also, HDPE systems are often breached when heavy equipment is tracked over the HDPE plastic liner.
