10 Years Ago – Stewart & Stevenson– Stimulated to continue century-Long Tradition of Excellence

It was in early 2007 when Stewart & Stevenson LLC of Houston, Texas acquired Calgary-headquartered Crown Energy Technologies, Inc., a leading manufacturer of drill­ing, well servicing, workover rigs and stimulation equipment.

“As a result of this acquisi­tion, Stewart & Stevenson will be the largest provider of well stimulation equipment in North America,” said Robert L. Hargrave, CEO of Stewart & Stevenson, at the time.

The company, which em­ploys 3,400 people worldwide, including 450 in Calgary, has major manufacturing facilities in Canada and the U.S. It also has 54 locations across the globe, including Colombia, Venezuela, China and Russia.

In business for more than 100 years (it was founded in 1902), Stewart & Steven­son’s diversified product offerings include equipment for well stimulation, well workovers and service, drilling, coiled tub­ing, cementing, nitrogen pumping, power generation and electrical systems as well as engines, transmissions and materials handling equipment.

“Acquiring Crown was a perfect match for us,” explains Stewart & Stevenson Canada General Manager Michael Hauser, who has been with the company for 14 years and in the manufacturing business for more than three decades. “Crown’s stimulation equipment complemented our U.S. stimulation equipment. And on the rig side, it was the best opportunity for us to get into that market.”

Since the 1950s, Stewart & Stevenson has engineered quality well servicing products to support the oil and gas industry— onshore, offshore and around the world, from the waters of the Gulf of Mexico and Caspian Sea to the deserts of the Middle East and the coldest re­gions of Siberia. Products manufactured by Stewart & Stevenson Canada build on this tradition.

“We offer the most complete line of stimulation equipment available, which means we can meet your application’s re­quirements from start to finish, whether you need acidizing equipment or a fracturing pump,” says Hauser, “And when it comes to customer service, you can count on Stewart & Stevenson to be there every step of the way, from helping you design the equip­ment best suited for your application to the final commissioning in the oilfield.”

For workovers, Stewart & Stevenson offers Flushby, 200, 350 and 550 models designed for lightweight, durable and ver­satile rigs. Known for fast and easy rig-up and user friendly operation and mainte­nance, these self-contained units have very few removable parts and require little or no assembly at the job site, thus benefiting customers with reduced downtime and saved man-hours. Like other units, these rigs are available in carrier-, trailer- or skid-mounted configurations.

The company offers equipment refur­bishment that ranges from simple cleaning, repair and a new paint job to a complete rebuild. “We have the talent and tools to complete any refurbishment, whether it is for a rig or a fleet, an engine or a genset, a transmission or other equipment,” explains Manager of Rig Programs Dave Keck, who has 33 years in the industry.

“Our team of experts has the mechani­cal, electrical and structural repair experi­ence to accomplish any refurbishment, quickly and cost effectively. The end result is a like-new product at nearly half the cost that will provide years of extended service life,” he continues. “Our on-site testing capabilities allow us to hydraulically pull test up to 1 million pounds.”

Also of interest are the company’s AC/VFD control systems, which are devel­oped completely in-house. Each includes a custom-designed control panel for ease of operation, connecting and operating every piece of rig equipment on the rig site.

Engineered Oilfield Products

– Stimulation Equipment

Stewart & Stevenson’s stimulation equip­ment is renowned across the globe. “Here in Canada, we offer frac equipment, blend­ers, data vans, coiled tubing rigs, acidizers, cementing and nitrogen units,” Hauser explains. “Our stimulation equipment is cus­tomized to suit our clients needs and we are focusing our energy towards new products in international markets.”

Fracturing Equipment – Stewart & Stevenson developed the world’s first 100 barrels per minute blender in 1959. Fast forward close to 50 years and you’ll find the company is still innovating and setting the industry standard with some of the most reliable, efficient and productive equipment available.

“Our blenders feature highly efficient closed loop hydraulic systems that provide faster response than open loop systems while consuming less power and produc­ing less waste heat for longer component life and reduced maintenance require­ments,” Hauser says. “Our AccuFrac System provides automated density and chemical controls in a user-friendly interface that can be installed and operated from the unit or a data van.”

Such equipment as pumpers, blenders and data vans are now manufactured in Canada.

Hydration and Chemical Additive Systems – These systems are designed to provide polymer injection and hydra­tion to eliminate post-job waste while increasing slurry viscosity. Stewart & Stevenson’s units, equipped with the AccuFrac System, allow the operator to tailor fluid systems to perform the most difficult treatments on the fly while auto­matically proportioning chemicals.

“As with other units in our extensive line of stimulation equipment, we offer a variety of configurations and packages to best suit your application. We can custom-design your equipment to feature trailer-, truck- or skid-mounted configurations,” he explains. “The system is also available as a standalone chemical additive unit or a combination chemical additive and hydra­tion blender.”

Acidizing – Stewart & Stevenson acidiz­ing units bring high horsepower pumping, acid transportation and fluid mixing capa­bilities to the wellsite in a single unit pack­age. “Our units are efficiently designed and fully integrated, allowing operators to accomplish multiple acidizing treatments quickly so they can move on to their next job,” says Hauser.

Data Acquisition and Control Centres – Getting the right information at the right time can be the difference between a quality treatment job and ruining a

well. Thanks to a user-friendly interface that provides real-time data about the ongoing fracturing treatment, Stewart & Stevenson’s Data Acquisition and Control Centres greatly improve job quality while providing a centralized and comfortable command centre to monitor and control all critical well site equipment.

The company’s AccuFrac System, for example, is included with the Data Acquisi­tion and Control Centre, allowing clients to control a variety of stimulation equipment, including blenders, hydration units and chemical additive units. “This enables you to reduce the number of equipment opera­tors required to complete the treatment,” he explains. “Up to 24 fracturing pumps can be controlled through a single work­station, and the centres come equipped with UPS systems and solid-state CPUcomponents to minimize downtime.”

Stewart & Stevenson’s wireless option provides for a “cable free” wellsite.

Cementing – The company has designed and manufactured cementing equipment for the oilfield since the 1950s. Stewart & Stevenson’s high-energy, recir­culating mixing systems, available with or without automated density controls, provide consistent cement density profiles that meet the most difficult job require­ments. The company’s cementing systems include batch mixing units and high-pres­sure pumping.

Coiled Tubing – Since beginning the design and manufacture of coiled tubing equipment in 1990, Stewart & Steven­son has positioned itself as one of the industry’s leading suppliers of high-qual­ity, reliable fit-for-purpose coiled tubing equipment to service companies world­wide for onshore or offshore applications. The company is best known for its light­weight, high pull capacity injector heads. Custom projects in Canada have pioneered CT products with masts, something unique to company operations.

Nitrogen – Stewart & Stevenson manufactures nitrogen pumping units in fired and non-fired (heat recovery) versions. It also manufactures non-cryo­genic gaseous nitrogen generation using membrane technology.

As for nitrogen pumping systems, the company is an original equipment manufacturer of vapourization systems for use in the oilfield services and under-balanced drilling industries. Standard configurations to vapourize and pump nitrogen provide from 90,000 SCFH to 1,200,000 SCFH at discharge pressures up to 15,000 psi.
