NuWave Industries Inc. brings you an innovative well abandonment solution that offers dramatic improvements over traditional cut-and-cap methods.

NuWave’s patented mobile hydro-cutting system offers increased safety, minimal environmental disturbance, and saves you time and money!

NuWave Industries’ safe, clean well and pipeline abandonment system is a true game-changer in the oil and gas industry. Once you see the NuWave system in action, you’ll never cut and cap any other way!

NuWave Industries’ technology is Canadian-designed, patented and AER-approved. Our safe, clean well abandonment method is suitable for oil wells, natural gas wells, pilings and pipeline risers. We serve clients across Alberta and British Columbia. Our hydro-cutting (water jet) system is compact and mobile, suitable for use on any terrain, in any weather conditions. It’s especially well suited to the demands of jobs in the wet muskeg conditions found in northern Alberta.

How are we different? Old vs. NuWave

Traditional Excavation Method

  • Excavate a wide, sloped hole around the wellhead, at least two meters deep.
  • Any water down there? (If you’re working in the muskeg up north, you bet there is.) You’re going to need to hydrovac that out and keep it dry the whole time.
  • Construct and place a stable entry walkway. (This will have to double as a fast escape route in case of spark-related mishap).
  • Send the welder down into this sloped, hopefully not-too-damp hole, where he’ll use a cutting torch to (slowly) cut through the outermost layer of steel casing.
  • Use a sledgehammer to knock away the layer of cement between the outer casing and the next layer of steel. (It makes your back hurt just thinking about this.)
  • Repeat the cutting and smashing steps for each layer of casing and cement lining. Will there be two? …Three? …Four?
  • Careful with that torch on the innermost layer. Things could get real hot in a hurry.
  • When it’s finally severed, hoist the pipe out of there.
  • Weld a cap on top of the exposed casing strings.
  • Get people and equipment out of the hole.
  • Remove any soil contaminated in the messy cutting process.
  • Backfill the hole (probably with fresh dirt you had to truck in to replace potentially contaminated soil).
  • Everyone can leave now! Maybe there’s time to do one more well today. (Hooray.)
  • Come back again in a year when the ground has had time to settle. Fill in with more dirt.
  • Come back the next year to see if you need to do that again.
  • Apply for environmental reclamation certificate. It should only be a couple more years (okay, maybe five) until the site is back to its “natural state” and your responsibility for it is complete.

The NuWave Process

  • Remove wellhead from the top of the well.
  • Place NuWave’s patented Ultra-HighPressure Hydraulic Sub-Level Pipe Cutter inside the innermost casing.
  • Hook up water and abrasive lines and fire up the pumps.
  • High-pressure water delivers abrasive to a cutting tip two meters below surface. The tip rotates inside the casing, making a smooth cut from the inside out.
  • Depending on the thickness and number of casing layers, it can take 20 minutes to an hour to complete the cut.
  • Remove tool and pull the casing out of the ground with a backhoe. Look on with pride at how little ground disturbance you’ve created.
  • Compression fit our AER-approved vented cap to the below-ground casing strings.
  • Backfill the “gopher hole” and you’re done.
  • Oh, are you still working on that excavation? Okay, well, we’re going to go complete five more NuWave abandonments today…
  • With minimal ground disturbance, the site returns to its natural state very quickly. You could have your environmental reclamation certificate in less than a year.

Save Time and Money

NuWave’s hydro-cutting process takes from 20 minutes to an hour(depending on the number of layers of casings and cement). The traditional excavation cut-and-cap method, in many cases, can take all day to complete a single well. In that same day’s time, NuWave can complete up to six abandonments.

NuWave’s technology is mobile and portable. It works on any terrain, in any temperature. The system is ideal for use in wet muskeg conditions, where you would otherwise require a hydrovac or two running constantly to keep the excavation dry.

Saving on time, manpower and resources all works out to saving big money!

Safety

NuWave’s greatest innovation is the tremendous increase in safety. For starters, you’re not putting a man down a pit—that eliminates all kinds of potential injury hazards, including cave-in, right there.

There’s no exposure to harmful gases or chemicals.

NuWave’s process involves no flame or sparking tools, eliminating dangerous fire hazards.

Environmentally Friendly

The NuWave system uses only water and natural abrasives—no harmful chemicals.

The procedure involves minimal ground disturbance, dramatically reducing the time it takes for the area to return to a natural state. With traditional excavations, it can take three to five years to get your environmental reclamation certificate. NuWave sites have received theirs in as little as eight months.

In response to our clients’ needs, we have adapted our wellbore abandonment technology to pipeline risers and pilings.

The system uses a miniature version of our hydro-cutting tool suitable for use in pipes as small as two inches.

The process is similar to well abandonment, with one significant adjustment: an engraved, AER-approved plug is installed in the pipeline first, and the cut is made above it. This ensures that no soil enters the pipe when the casing is removed—and nothing from the pipe comes in contact with its surroundings—no matter the conditions of the ground or angle of the pipe.

Depending on the size of the pipe, it takes 4 to 10 minutes to complete the cut. (Compare that to 4+ hours for an excavation.) Start to finish, the entire job takes 20 to 30 minutes.

We can complete seven or more pipeline abandonments in a day. We can cut and pull up to 30 pilings per day. The speed and efficiency of the NuWave system results in tremendous cost savings, coming in around one-third the cost of an excavation project of similar scope.

And it comes with all the convenience, safety, and environmental benefits inherent in the NuWave system!
