Three major value points of PRO-ROD Reduce Maintenance Increase Production Enhance Profit Pro-Rod delivers the most convenient and cost-effective coiled rod product and is the industry's largest coiled rod manufacturer, with world-class facilities in Canada, the United States and the Middle East. Coiled rod is manufactured as a one-piece, continuous rod string that effectively connects the bottom-hole pump to the prime mover at surface. With only two connections, one at the top and one on bottom of the rod string, all other connections are eliminated for a uniform rod diameter. Costly well maintenance interventions due to failures associated with rod couplings, tubing wear and coupling makeup issues are significantly reduced. Coiled rod's uniform and flexible nature makes it the most effective and efficient choice for rod strings in all wells deviated from vertical (horizontal, slant or directional). Our coiled rod is manufactured using the highest quality domestic steel available and is subject to the industry's most rigorous quality assurance program. Pro-Rod s proprietary high-quality, fully quenched and tempered coiled rod is available in the size and grade required to meet your needs. REDUCE LIFT COSTS Failure analysis data indicates that the majority of conventional sucker rod string failures occur within the coupling connections and forged upset areas. Pro-Rod s connectionless rod string with uniform rod diameter can drastically reduce the associated costs of rod string maintenance, tubing replacement and well downtime. INCREASE PRODUCTION Removal of the couplings from a rod string creates a uniform flow area for fluid in the production tubing and eliminates pressure loss experienced across couplings, increasing both pump efficiency and production. reduce SERVICE COSTS Firstly, producers can expect lower well service costs by reducing well intervention frequency utilizing Pro-Rod. Secondly, coiled rods one-piece configuration also helps to significantly reduce trip times, rod handling and manpower associated with conventional sucker rods. 2
BENEFITS OF COILED ROD Bringing the benefits of coiled rod to your oilfield, simply and efficiently Coiled rod technology has been available since the 1960s but remained a relatively under-utilized product due to the significant logistical obstacles it once presented for well operators. Recent advances in the equipment used to install and maintain coiled rod-equipped wells, coupled with an increased availability of third-party coiled rod installation services, have removed the cost-prohibitive barriers of entry and revolutionized the utilization of coiled rod in the industry. Pro-Rod and Dover Artificial Lift have been at the forefront of these recent advances. Thanks to state-of-the-art installation and servicing equipment, coupled with coiled rod manufactured with industry-leading steel strength and quality, oil producers can now leverage coiled rod in any type of well, in a manner that ensures optimal production and drastically reduces well maintenance costs. The Benefits of Coiled Rod INCREASED PRODUCTION By removing couplings, centralizers and guides from the rod string, coiled rod helps boost production by providing: Increased annular flow area Eliminates pressure drop across couplings/centralizers/guides Eliminates rod coupling/centralizer piston effect Allows for utilization of larger diameter rod in slim-hole applications ROD IN PRODUCTION TUBING Conventional coupled rod Coiled rod Conventional sucker rod Coiled rod with coupling 3
BENEFITS OF COILED ROD CONTACT LOAD & TUBING WEAR Couplings on conventional sucker rod (left) generate high concentrated contact loads and bending stresses especially in deviated tubing sections. Coiled rod's uniform diameter (right) allows for a more uniformly distribution of loads which decreases contact loads and bending stresses. Tubing Sucker Rod Concentrated Contact Load Tubing Uniformly Distributed Contact Area Coupling or/and Guide Coiled Rod Reduce Well Downtime and Maintenance Eliminating couplings prevents an estimated 75% of rod string failures Coiled rod distributes side loads more effectively than conventional sucker rod throughout the entire rod string, which eliminates the concentrated wear caused by couplings every 25 feet to significantly reduce tubing wear SUCKER ROD IN TUBING SUCKER ROD COUPLING & Tubing WEAR 4
PRO-ROD APPLICATIONS Optimizing Production Across a Range of Rod-Driven Pump Systems Pro-Rod has earned its reputation as an industry-leading rod lift solution for a variety of well configurations and artificial lift applications. Reciprocating Rod Lift Reciprocating rod lift (RRL) remains the most widely utilized method of artificial lift around the globe. Coiled rod can complement most RRL systems, particularly those producing from horizontal, or directional well profiles. Pro-Rod enhances these systems by reducing tubing wear, improving pump and surface equipment efficiencies, and increasing production in both light-and heavy-oil applications. The removal of rod couplings along the entire length of a rod string achieves several key efficiencies to reduce your lift costs: Eliminates rod coupling failures with the majority of rod failures confined to the coupling/upset area. Reduces tubing wear by distributing contact loads over a larger area. Reduces rod stress. Creates unrestricted laminar flow through uniform rod diameter. Eliminates the piston effect common to conventional sucker rods, which reduces friction and increases plunger travel for increased production. Makes Pro-Rod a more efficient and longer-running alternative to coupled sucker rods. Coiled rod lowers maintenance costs, as overall rod stress and tubing wear are reduced, particularly in the case of deviated wells. With lower rod stresses, surface drives can be downsized, thus lowering capital and energy costs, and downhole pumps can be upsized to provide increased production. The absence of couplings also creates a more uniform diameter, resulting in reduced pressure losses, a lower likelihood of paraffin deposition and buildup and a less turbulent flow profile up the production tubing.

PRO-ROD APPLICATIONS Progressing Cavity Pumping Progressing cavity pump (PCP) systems are a popular lift option in wells characterized by mid to low API gravity oil. In many regions this viscous oil is produced along with sand (solids) cuts that create conditions unfavorable to the utilization of conventional rod with couplings. The presence of solids in a vortex condition around each coupling increases the risk of abrasive coupling failure. In addition, the flow restrictions created by the couplings decreases the pump's Polished Rod ability to effectively lift fluid/solids to surface. The streamlined profile of Pro-Rod coiled rod helps to enhance the operational efficiency of PCP systems by reducing rod and tubing wear as well overall rod stress. Lower rod stress allows the operator to downsize the surface drive, thus lowering operating costs, or upsize the PC pump to increase flow rates to the surface. The streamlined profile of coiled rod enables laminar flow of fluids to surface which minimizes problems associated with solids fall-out. This profile also allows for coiled tubing clean-outs to remove solids down to the top of the pump. Additionally, without having to make-up a coupling connection every 25 feet, Pro-Rod strings are installed faster and with less manpower.

CASE STUDY The Case for Pro-Rod Pro-Rod works with a major Canadian heavy oil producer for drastically increased mean time before system failures, substantial service cost savings and enhanced production. Understanding the Challenge Reduce well intervention frequency in their CHOPS (Cold Heavy Oil Production with Sand) wells. The harsh conditions of the wells in question caused excessive tubing and rod string wear, especially in the rod coupling area. This led to frequent interventions, high service costs and less than optimal well production. Average mean time between system failures was roughly 9 months, much shorter than ideal or possible. Identifying the Right Solutions Pro-Rod replaced the traditional conventional coupled rod with coiled rod. Pro-Rod was installed into 1,500 wells, initially as a pilot study. Due to the documented early success of the product and service model, the company elected to convert 3,500 producing wells and install all new drills to Pro-Rod coiled rod. The service model warranted the deployment of 20 Pro-Rod coiled rod injectors directly into the company's service equipment fleet over time. Pro-Rod also provided coiled rod injectors to third party contractors to ensure full and on-going coverage for this producer. This model alleviated the inconvenience and service delays typically associated with coiled rod-driven production. The pilot also proved that the servicing of coiled rod was much more efficient compared to conventional coupled rod. Delivering Results In the wells monitored by the pilot, net well service costs were reduced by $1,600 per well, per month, for a total field-wide savings of $2.4 million per month. The mean time between system failure was improved by 33%, from 9 to 12 months. This represented significant savings due to a decrease in service costs. The average time for the first intervention on a new well was improved by 200%, from 3 to 9 months. This decrease in site downtime improved overall production by 10%, or 258 barrels per month per well. SAVE $2.4M SAVINGS OF $1,600 / MONTH per well, per month MTBF 33% increase PRODUCTION 10% increase 8
