Mountain Equipment Trash Catcher FAQ

What is a trash catcher?

Simply put, a trash catcher is a device used to collect and isolate debris (also called 'trash' or 'junk') from the flow of a wellhead. The debris, such as drill-out plug particles or frac balls, can be harmful to machinery and instrumentation further downstream. A trash catcher allows for the capture and disposal of this debris and can prevent the well from needing to be shut in for clean out.

How is a trash catcher used?

Trash catchers are the first piece of equipment to handle the flow of a well during drill-out. By being placed upstream of all other equipment, the trash catcher protects other in-line equipment and instrumentation. The trash catcher is installed so that the flow enters the first barrel of the trash catcher. This first barrel is connected to a second barrel via small connections which allow gas and liquids to pass through, but block any large solids. Once the first barrel clogs with solids, a pressure differential develops between the two barrels and the operator can then purge the first barrel of material for proper disposal by blowing it down. Trash catchers are being increasingly utilized as the popularity of fracing grows worldwide.

What pressure can the trash catchers handle?

Since the trash catcher is exposed to high shut in pressures near the well head, a trash catcher is rated to handle high pressures. Our trash catchers are rated for 7500 psi MAWP. 10,000 psi is also available for custom orders; please discuss your requirements with your sales person.

What size debris can a trash catcher handle?

Our unique "triplet" trash catcher has the ability to handle debris of a variety of sizes. The first trash barrel captures larger debris ranging from 3/8" to 2-1/2" in diameter. The second barrel captures smaller debris from 1/4" to 3/8" in diameter. The flow is then directed into a sand trap which captures debris smaller than 1/4" and fine sand.

Does the well need to be shut in when one of the barrels clogs with debris?

No. Each barrel of a trash catcher can be blown down independantly without shutting in, providing the trash catcher is rigged up with a bypass.

How long is a trash catcher needed on site?

A trash catcher is needed upstream of other equipment as long as the well is producing debris. A well may produce persistent trash, or it may clear; it depends on the methods used to frac and complete that well.

What different types of trash catchers are there?

We manufacture three different types of trash catchers: a double-barrel model, a quad-pack model and our 'triplet' model. The triplet can handle sand as well as debris.

Do you offer NACE trash catchers?

Yes we do. Please be sure to discuss your sour service needs with your sales person.

How do I get a trash catcher on-site?

Our trash catchers are mounted on heavy-duty oilfield skids, but are easy to transport. A forklift or winch truck should be sufficient to load/unload.
