Fracing vs. Fracking: Winning the Grammar Battle and Losing the Search Engine War


Hydraulic fracturing is the drilling process where layers of bedrock are cracked and spilt using hydraulic fluids to free up and extract oil and natural gas trapped within. TECO is a manufacturer of severe service magnetic flowmeters designed specifically for the hydraulic fracturing industry.

We at TECO believe its important to fully understand an industry's unique processes, challenges, and terminology. By doing so we gain a deep industry knowledge. This knowledge facilitates better communication. Better communication increases understanding and reduces mistakes and errors.

There are very few situations where this isn't the best track to follow. But we found one.

We always tried to do our best by being clear, accurate, and following industry standards. But sometimes you just have to know when to give up. Such is the case with the never-ending "fracing vs. fracking" debate.

This isn't the first essay on the subject, and it won't be the last. It's just that, we here at TECO, have decided to change our online communications approach, based upon some pretty strong data.

While the Oil and Gas industry prefer leaving that lower case "k" out, it's become quite clear that Mr. Google and Mr. Webster decided the "k" needs to be there. And when you're a company making great flow meters, and trying to let people know how good they are, it's makes a world of difference in getting found on the search engines.

It's no secret that Oil and Gas industry people clearly prefer the use of frac or fracing. There are quite a few instances where industry leaders have strongly argued that frac or fracing are the only acceptable spellings. TECO too, decided the industry preferred version was the way to go, and decided that all of our efforts in online marketing and communications would follow suit. We were sure that by sticking to the use of the industry preferred spelling, we'd be in a perfect position to be seen by all the industry professionals searching for "fracing flow meters".

But that didn't happen. Mr. Google wasn't buying it. Search engine results were disappointing. We needed to find out what we were doing wrong.

After careful review of our online content, and use of keywords, we determined it was that lousy lowercase "k". Turns out it makes an insane amount of difference when people use a search engine.

For example, in one test, using a generic keyword tracking tool, we found that the term "fracing" returns a total of 1187 searches, while the term "fracking" returns an astounding 87,836 searches! That means "fracking" is searched for 74 times more than "fracing". You can't ignore that.

Additionally, when you review the Google Trends graph below,  you see a vivid illustration of the usage (and trends) for the terms Frac, Frack, Fracing and Fracking (it's pretty clear that Fracking is the winner).

But this graph also reveals another important geographic clue. You'll note that the term Frac is used in the specific states where the actual drilling is happening, which makes sense because that's where the fracing industry professionals are. And we want to make sure we reach them. So, our conclusion and online marketing plan may not surprise you.

We'll use both. 😀

Magnetic Flowmeters for Fracing

Fracing
Fracing illustration (USGS)
Hydraulic fracturing, or fracing, is the process of exploiting small fissures or cracks in rock layers deep under the earths surface, and increasing their number and size for the purpose of freeing up trapped natural gas. The process includes drilling horizontally in the bedrock and then forcing "frac fluid" into those cracks under very high pressure. The fracturing fluid is made up of water, a special type of sand (referred to as the proppant) and a mixture of chemicals.

Flow measurement is very important in fracing and requires instrumentation with long life and high accuracy.  Frac fluid is a very nasty slurry and it's flow measurement is challenging. Flow instruments are exposed to high pressures, erosive materials and corrosive chemicals.

FracingFrac sand is very erosive and the high pressure and corrosive chemicals complicate things exponentially. Any flowmeter used in fracing applications must not only be rugged enough to withstand these harsh conditions, but the flowmeter must also provide the accuracy required for reliable data reporting to supervisory agencies. Cost-effectively meeting accuracy and longevity requirements for these applications can be frustrating.

Magnetic flowmeters have always appealed to the fracing industry because of their unfettered flow path, availability of sizes and level of accuracy. Their downfall is their longevity. Standard, off-the-shelf magnetic flowmeters don't last in this environment and can't be considered an economically viable choice.

An excellent solution that provides all the the virtues of magnetic flowmeters, and overcomes the longevity and economics issues, are specialized magnetic flowmeters. Referred to as "severe service flowmeters" or "slurry flowmeters", they are designed with components matched specifically to withstand the mechanical and chemical abuse they will see.

Magnetic flowmeters, specialized for fracing, provide all of a "magmeters" desirable features with these critical enhancements:
  1. A ceramic sleeved liner made of magnesia partially stabilized zirconia. This ceramic can handle the abrasion and chemical attack with very little degradation.
  2. Highly polished, ultra-smooth Tungsten electrodes. The Tungsten provides outstanding wear resistance while the high-polish reduces electrical noise introduced in the electrode circuitry.
  3. Special coatings, or paints, to provide exterior protection.
Fracing flowmeterBy specifying magnetic flowmeters, specialized for fracing, not only do operators save money through increased uptime and decreased health, safety and environmental risk, but also through reduced costs related to flowmeter purchase and repair.

Magnetic Flow Meters with Specialized Construction Still the Best Bet for Dredging Applications

dredgers
Electromagnetic flow meters commonly measure slurry mixture flow on cutter suction dredgers and trailing suction hopper dredgers. These type of flow meters use exposed electrodes and non-conductive flow tubes. Ordinary magnetic flow meter flow tubes  are not designed to withstand the abrasive conditions prevalent in dredging. Standard magnetic flow meter electrodes  are prone to wear, breakage, and polarization requiring frequent re-adjustment. Standard electrode seals may also deteriorate and cause leaks and false readings.

dredgersAs an alternative, non-invasive (non-wetted) flow meters, such as clamp-on or Doppler ultrasonic flow meters, have long been proposed because of their  ease of installation and maintenance savings. However, testing of clamp-on or Doppler ultrasonic flow meters has never panned out in dredging applications. While there has been limited success on smaller sized diameters, there are few, if any, large diameter dredging pipe application success stories.

Dredging engineers always seek the simplest and most accurate method of measuring slurry flow. Considering this, there is convincing evidence that the use of customized electromagnetic flow meters, specifically designed to stand up to the rigors of dredging, look to be the best overall option.

Dredging-specific flow meters provide wear solutions that can extend the life of equipment and keep systems at maximum operational levels. Some users report life span up to 10 years.

The dredging modifications include custom engineered ceramic brick or polyurethane liners, 3/4" stainless steel inlet and outlet protectors, independently sealed electrode wells, and field accessible Hastelloy B electrodes.

Thompson Equipment (TECO), a manufacturer of severe service magnetic flow meters located in New Orleans, will "remanufacture" any make or model of electromagnetic flow meter for dredging service. They have decades of experience servicing and remanufacturing instrumentation, and are leaders in building severe service flow meters.

Electromagnetic flow meters have always been appealing for dredging applications in terms of accuracy, resolution, and response time. Their performance problems, caused by the direct and continuous flow of abrasive slurries, are mitigated through specialized construction.  By applying electromagnetic flow meters specifically designed for the application, dredging engineers now achieve excellent reliability, long life and significant reduction in maintenance and operational costs.






Electromagnetic Flow Meters for Accurate Measurement of Flowing Conductive Fluids and Slurries

In general, magnetic flow meters are sturdy, reliable devices able to withstand hazardous environments while returning precise measurements to operators of a wide variety of processes. The magnetic flowmeter has no moving parts. Electromagnetic meters will measure virtually any conductive fluid or slurry. This includes process water and wastewater. They provide low pressure drop, high accuracy, high turndown ratio, and excellent repeatability.  It is however, necessary to fill the entire cross section of the pipe in order to derive useful volumetric flow measurements.

Electromagnetic flow meters employ Faraday’s law of electromagnetic induction, whereby voltage is induced when a conductor moves through a magnetic field. The liquid acts as the conductor, with energized coils outside the flow tube creating the magnetic field. The produced voltage is directly proportional to the flow rate. Magnetic flow meter technology is not affected by temperature, pressure, or density of the subject fluid.

Electromagnetic flow meters tend to be heavy in larger sizes and may be prohibitively expensive for some purposes. However, irrespective of price and size, there are multiple reasons why magnetic flow meters are the instrument of choice for certain applications. They are resistant to corrosion and their ability to accurately measure dirty fluids makes them very suitable for wastewater measurement. As mentioned, there are no moving parts in a magnetic flow meter, keeping maintenance to a minimum. Power requirements are also low. Electromagnetic flow meters are available in a wide range of configurations, sizes, and construction materials to accommodate various process installation
requirements.

Severe Service Magmeters for Fracing Operations

Proven in the heat of a West Texas summer, and the cold of an Alberta winter, this TECO magmeter is designed from the ground up to withstand corrosive slurries, acids, bases and solvents.



Severe Application Meter

Magnetic flow meters (magmeters) installed on blender trucks are of particular concern. The application involves accurately measuring the flow of an extremely erosive slurry comprised of sand and “frac water” (a mixture of water and harsh chemicals). Replacing failed magmeters can take up to 4 hours, and requires the shutting down of the entire frac spread.

Calling upon sixty-plus years experience in magmeter application, failure analysis, repair, and design, TECO developed several innovative magmeter features intended to improve longevity in fracing operations.

First, TECO developed a ceramic sleeved liner made of “magnesia partially stabilized zirconia”, a very tough ceramic used in severe-service applications that provides corrosion resistance and durability.

Second, TECO developed electrodes built from a solid tungsten carbide billet, which afford unparalleled wear resistance. Given the sand density in the frac fluid, noise reduction is critically important; so, the tungsten carbide is polished leaving a hard, smooth finish that significantly reduces noise in the electrode circuit.

FRAC Sand
Erosive sand tears up
other magmeters. 
Finally, TECO designed the magmeter as a drop-in replacement. It operates with a variety of secondaries and matches the “lay length” of the meter being replaced. There is no need for a new transmitter and no need for repiping, allowing for simple retrofit in existing installations.
