Where Calgary actually made things

The Calgary most visitors see is a downtown of glass towers, the Bow River pathway and a ten-day rodeo. The Calgary that built those towers is southeast of the tracks. Manchester, Highfield, Bonnybrook, Ogden and Alyth are a continuous belt of rail yards, tank farms, rendering plants, gas utilities and heavy industry running along the Bow, and they have been there since the Canadian Pacific Railway decided in 1883 that this bend in the river was where the divisional point would go. Imperial Oil ran a refinery in the southeast for decades before closing it in the mid-seventies. The Ogden shops built and repaired locomotives for most of a century and turned out naval gun mountings during the Second World War. Bonnybrook still handles a good share of the city’s heavy utility load.

It is a part of the city with almost no tourist appeal and enormous relevance to what Tundra Engineering does. Oil treating and battery work is the least photogenic corner of the industry — tanks, treaters, separators, truck-in facilities, a flare and some mud — and it is where a very large share of Alberta’s production revenue is actually realised. If the battery does not make clean oil to spec, nothing upstream of it matters.

The neighbourhoods around that industrial belt tell the other half of the story. Inglewood, the oldest surviving neighbourhood in Calgary, sits directly between the rail yards and the river and has spent thirty years turning warehouses into record shops, book stores, breweries and restaurants without evicting the industry that gave it a reason to exist. Ramsay looks down on the Stampede grounds from a hill of century-old workers’ cottages. Bridgeland was the Italian and Ukrainian quarter and now has some of the best food in the city. This is a place with an unusually honest relationship between its industrial base and its cultural life, and it is one of the reasons engineers stay.

Oil batteries and oil treating

An oil battery is the surface facility that takes raw well effluent — oil, water, gas, sand, emulsion and whatever else the reservoir sends — and separates it into a saleable crude stream, a gas stream that is conserved or flared, and produced water that is disposed of or reinjected. The equipment list is short and the process is anything but simple: inlet separation, free water knockout, heater treaters or electrostatic treaters, chemical injection and demulsifier selection, tankage with the right vapour handling, LACT measurement and proving, truck-in and truck-out facilities, produced water handling and the vapour recovery that keeps the whole thing legal.

Tundra’s work here spans new batteries, expansions, consolidations and the troubleshooting of facilities that have stopped performing. Emulsion problems are the most common complaint and rarely have a single cause: a change in water cut, a new well with different fluid chemistry, a demulsifier that no longer suits the blend, residence time lost to sand accumulation, a treater running below design temperature to save fuel, or upstream chemical incompatibility. Diagnosing it properly requires field sampling and bottle testing rather than a catalogue.

Sand and solids deserve a special mention in Alberta. Many of the formations produced here deliver enough sand to change vessel residence time within a couple of years of start-up, and a battery that was correctly sized on paper will underperform if nobody accounts for the volume of solids sitting in the bottom of the free water knockout. Designing for cleanout access is worth more than an extra metre of vessel.

Consolidation is the other recurring theme. Alberta is covered in small batteries built one at a time as pools were developed, and as fields decline the economics of running twenty small facilities collapse. A consolidation study — which sites can be tied together, what the gathering hydraulics allow, what the emissions and trucking picture looks like afterwards, and what the closure cost of the abandoned sites is — is one of the highest-return pieces of engineering a mature-asset operator can buy.

Vapour, emissions and the tank farm nobody thinks about

Storage tanks at a battery are a quiet source of emissions and a recurring compliance problem. Flashing, working and breathing losses from tanks handling live crude can be substantial, and Directive 060 has steadily tightened what is acceptable. Vapour recovery units, properly sized and actually maintained, convert a reported emission into a sold volume. We size them, specify them and, just as importantly, look at whether the site can keep one running — a VRU that trips every second week and gets bypassed is worse than none, because it exists on the emissions report as a control.

Truck traffic is the other externality. A battery with a heavy truck-in schedule generates road damage, dust and complaints from the county long before it generates a regulatory problem, and the fix is usually pipeline connection rather than diplomacy.

The regulatory frame

Batteries in Alberta are licensed under Directive 056, measured and reported under Directive 017, and constrained on flaring and venting by Directive 060, with waste handling under Directive 058 and closure obligations under the licensee liability framework. Measurement is where operators most often get into trouble, because allocation between partners depends on it and an audit that finds a proving gap becomes a commercial problem rather than a technical one.

We prepare the applications, build the measurement schematics and reconcile the volumes, and we do it with the assumption that the file will eventually be read by somebody who was not there when it was written — an auditor, a purchaser, or the engineer who inherits the asset.

Working from Calgary

Everything about this work benefits from being close to it. The treaters and separators are fabricated in shops within an hour of the office, the chemical suppliers who will run your bottle tests are in the same industrial parks, and the fields are a morning’s drive. Our engineers can be at a battery, pull samples, talk to the operator who actually knows what changed, and be back at a desk the same day.

There is also the matter of institutional memory. Calgary is where the records, the previous owners, the original design consultants and frequently the retired engineer who commissioned the plant in 1987 all still are. On brownfield battery work that is a genuine technical resource, and it is not available anywhere else.

Culturally, this is a city that respects people who can fix things. The Stampede handshake and the downtown boardroom get the attention, but the industry’s centre of gravity is a lot closer to a shop in Foothills Industrial Park than to a tower on 5th Avenue, and the engineers who do well here are the ones who are comfortable in both.

If your battery is not making spec, your emulsion is getting worse, your tank vapours are showing up in your emissions report, or you are running more small facilities than the field can now justify, that is precisely the work this group does.

Small facilities, real money

Battery work rarely attracts the attention that a new plant does, which is exactly why it is often the best return available to a mature-asset operator. A treater running twenty degrees cooler than it should, a demulsifier that has not been re-tested since the water cut changed, a VRU that has been bypassed for eighteen months, or a meter that has drifted two percent are individually unglamorous and collectively worth more than most capital projects on the list.

We look for those first. A field walk, a set of samples, a week with the historian and a look at the last three years of volumetric reconciliation will usually identify more value than a concept study, and it costs a fraction as much. Only when the easy money is gone do we start talking about new equipment.

Calgary is the right base for that kind of work because everything it depends on is here: the chemical suppliers who will run bottle tests, the measurement specialists, the fabricators who build treaters and separators, and the fields themselves a few hours away. Our engineers can pull samples in the morning and have results discussed the same week.

It also helps that this is a city with a long institutional memory of exactly this kind of facility. Somebody in Calgary designed, commissioned or operated almost every battery in the province, and a surprising number of them are still reachable. On brownfield oil treating problems that is not nostalgia, it is a technical resource, and we use it regularly.

If your oil is off specification, your emulsion is worsening, or you are running more small facilities than the production now justifies, start with a field assessment rather than a capital request.
