About Us


ESI’s mandate is to acquire and develop investments in the pipeline service sector in Canada, the United States and select international markets. ESI Energy Services Inc. (“ESI” or the” Company”) was incorporated as a numbered company under the Business Corporations Act (Alberta) on February 22, 2001. Pursuant to subsection 167(1)(a) of the Business Corporations Act (Alberta), the Company’s Articles of Incorporation were amended and the corporation changed its name to ESI Energy Services Inc. on September 12, 2001. The Company commenced operations in October 2001 with a mandate to enter the oilfield service business in western Canada. The Company has two wholly owned operating subsidiaries, ESI Pipeline Services Ltd. (Canada) and ESI Pipeline Services Inc. (United States). The two subsidiaries operate under the name of Ozzie’s Pipeline Padder. The Company's head and registered office is located at 500, 727 7th Avenue S.W., Calgary, Alberta. ESI also maintains service facilities in Leduc, Alberta and Phoenix, Arizona. The Leduc service center operates out of a 30,000 square foot office and shop complex situated on 12.9 acres of prime industrial land located within two miles of the Edmonton International Airport. The Phoenix service center operates out of a 29,400 square foot office and shop complex situated on 4.9 acres of light industrial land in west Phoenix. Both properties are Company owned. ESI employs approximately 34 employees, 5 of whom are based in the Company’s downtown Calgary, AB, corporate offices, 11 employees are located in Leduc, AB and 18 are located in Phoenix, AZ. The service centers in Leduc and Phoenix employ teams of fully qualified and experienced service technicians.

About the Business

ESI acquired Ozzie’s Pipeline Padder, Inc. (“Ozzie’s” or “OPI”) from a financial distress situation in August 2003. The Company exited the oilfield service business in September 2009 in order to focus on the pipeline equipment rental business. Since taking over Ozzie’s, the Company has restored Ozzie’s to profitability and re-established its reputation as a premium supplier of self-propelled, self-loading backfill separation machines (“Padding Machines”) to North American mainline pipeline contractors, utility contractors and renewables (wind and solar) contractors. ESI’s management has successfully restructured and reorganized the OPI’s management team, developed an impressive in-house design and engineering capability, and upgraded the fleet of 30 aging, mainline Padding Machines to meet the highest industry standards of performance, quality assurance and health, safety and environment. Ozzie’s also owns and operates a rental fleet of 15 Mini-padding machines which are powered by full size track loaders as well as a fleet of 3 Micro-padding machines which are powered by compact track loaders. The Micro-padding machines are our newest addition to our fleet of Padding Machines. The first Micro-padder was introduced in early 2017. Padding Machines are used by pipeline contractors to screen rocks and hard material out of the spoil pile, which is located on the side of an excavated pipeline trench, in order to backfill the pipeline located on the bottom of the pipeline ditch. Ozzie’s Padding Machines are self-propelled and self-loading. They operate by way of a single continuous pass through the spoil pile located parallel to the pipeline trench or ditch. Material is scooped up by the Padding Machine’s elevator system (the “Elevator”) which consists of a scoop and an inclined movable conveyor system which transports material from the bottom of the scoop up to the top of the Elevator where it is deposited on to a vibrating shaker system. The vibrating shaker system consists of a large rectangular metal box (the “Shaker Body”) over which a screen (the “Shaker Screen”) is placed. The shaker system is situated at approximately a negative 10 degree angle from the bottom of the Elevator running down towards the bottom of the lower back end of the Padding Machine. The purpose of the Shaker Screen is to prevent over-sized material from passing through the Shaker Screen and onto a conveyor system (the “Conveyor”) which is located below the lower part of the Shaker Body. When material from the Elevator is deposited onto the vibrating Shaker Body, the vibrating motion of the Shaker Body causes the under-sized material (material which is small enough to pass through the Shaker Screen) to pass through the Shaker Screen and fall onto the Conveyor which propels the undersized or screened material in a transverse direction towards the pipeline ditch where it falls under, over and around the pipe situated at the bottom of the ditch. The vibrating Shaker Body causes the oversized material (material which is too large to pass through the screen) to roll down towards the lower back end of the Padding Machine where it falls off of the Shaker Body back into the spoil pile. The size of the Shaker Screen can vary from 0.5 inches to as much as 4.0 inches, depending the backfill material specifications. The smaller the screen size, the smaller the material particle size that is allowed to pass through the Shaker Screen and onto, under and around the pipe. Typically, a smaller screen size on the Shaker Body will result in less material falling onto the pipe which results in lower backfill production. The purpose of screening the spoil pile before backfilling the trench is to prevent rocks and hard objects situated within the spoil pile from falling onto the pipe and puncturing the protective coating on the pipe and/or damaging the pipe during the backfill process. Padding is a “Green” alternative; it facilitates maximum ditch soil replacement and better soil compaction during the backfill process. Proper soil compaction helps to support the pipe firmly in place, preventing it from shifting or distorting as a result of unevenly distributed soil. Backfilling a pipeline trench with a Padding Machine as opposed to hauling in select backfill material eliminates soil contamination. Backfilling a ditch with a Padding Machine costs a fraction of the price of hauling in select backfill material such as sand or using other methods of pipe protection such as rock jacket or rock shield. Mini-padders and Micro-padders function in more or less the same capacity as large Padding Machines. They are basically compact versions of the larger machines and utilize scaled down versions of all of the same components their full size counterparts including: Scoop, Elevator, Shaker system and Conveyor. Mini-padders and Micro-padders are used for backfill separation during the construction of small utility pipelines, conduit and fibre optic cable as well as backfill separation of electrical cable during the construction of wind and solar projects.
