Description
- This application claims the benefit of U.S. Provisional Patent Application Ser. No. 61/555,523 filed Nov. 4, 2011, and U.S. Provisional Patent Application Ser. No. 61/581,884 filed Dec. 30, 2011, both of which are incorporated herein by reference.
- The present invention relates to liners that protect the environment from spills and leaks at sites such as oil and gas well drilling sites, and more particularly relates to berms for use with such liners.
- In conventional gas and oil drilling, large quantities of drilling mud, fracturing chemicals and flowback water are on site. Many operating companies compact the pad site and place a liner over the entire surface. The liner is pulled over earthen berms, railroad ties, corrugated pipe or foam blocks to form containment sidewalls or berms around the perimeter. The liner and berms then contain the leaks and spills so that on-site vacuum trucks can remove the waste without impact to the environment.
- There are issues with the current berm options. An earthen berm requires heavy equipment to build. The liner cannot be directly attached and requires staking. The earthen berms also tend to collapse into ruts under repeated vehicle traffic.
- While railroad ties can be moved from site to site for reuse, they are hard to decontaminate since they are covered in creosote and are absorbent to the chemicals on site. They require earthen ramps over top to move bobcats, skid steers, front end loaders, and track hoes on and off the pad site. The earthen ramp material inside the containment area absorbs the chemicals and must be landfilled afterwards. For tractor trailer traffic, the railroad ties need to be completely removed. Since durable liners are able to survive multiple operations in the well construction, this means that the berms may be removed and reinstalled up to five times. While the berms are out of position, the containment liner has an open sidewall. If a release occurs during that period, the liquids would flow off the edge of the pad.
- Corrugated pipe is easy to decontaminate due to its plastic construction. It is also light weight and easy to move. However, it is easy to crush and unable to support a ramp. It does not provide a physical barrier to traffic in sensitive areas and cannot be used in drive-over areas.
- Triangular and rectangular foam blocks underneath the liner provide easy drive-over sections. The drawbacks are: their limited weight which can allow wind uplift, and their poor resistance to being pushed forward into the pad. When the foam sidewall is pushed into the pad by vehicle traffic, the liner wrinkles. These wrinkles are tripping hazards for site personnel.
- The present invention provides berms for use with protective liners. In certain embodiments, the berms are configured to allow vehicular traffic to pass over the berms without causing damage. Such drive-over berms may be rigid and shaped to allow vehicle tires to pass over them, or may be resilient and collapsible such that they collapse when subjected to the weight of a vehicle tire and then spring back to shape after the vehicle passes. In certain embodiments, the berms may be stackable for storage and transportation purposes, and may include connectors for connecting multiple sections of the berms end-to-end.
- An aspect of the present invention is to provide a drive-over berm for use with a protective liner, the berm comprising a rigid base, and a berm body extending upwardly from the base structured and arranged to allow vehicular traffic over the berm.
- Another aspect of the present invention is to provide an interlocking berm assembly for use with a protective liner, the assembly comprising a first berm section having a connecting end, a second berm section having a connecting end, and at least one connector securing the connecting ends of the first and second berm sections together.
- A further aspect of the present invention is to provide a stackable berm for use with a protective liner, the stackable berm comprising opposing sidewalls extending upward from an open base, and a top connected to upper portions of the opposing sidewalls, wherein the sidewalls and top define an open volume inside the stackable berm, and are structured and arranged to fit inside an open volume inside another similarly shaped berm.
- Another aspect of the present invention is to provide a protective liner and berm assembly comprising a berm comprising a rigid base and a berm body extending upwardly from the base structured and arranged to allow vehicular traffic over the berm, and a protective liner covering at least a portion of the berm.
- These and other aspects of the present invention will be more apparent from the following description.
