ThREE mAjOR VALuE POInTS OF PRO-ROD®

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 COSTSFailure 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 PRODUCTIONRemoval 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 COSTSFirstly, 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.

Bringing the benefits of coiled rod to your oilfield,simply and efficiently

The Benefits of Coiled Rod

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.

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.

Reciprocating Rod LiftReciprocating 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.• Reducestubingwearbydistributingcontactloadsoveralargerarea.• Reducesrodstress.• Creates unrestricted laminar flow through uniform rod diameter.• Eliminatesthepistoneffectcommontoconventional sucker rods, which reduces friction and increases plunger travel for increased production.• MakesPro-Rod® a more efficient and longer-running alternative to coupled sucker rods.

Coiled rod lowers maintenance costs, as overall rod stressand tubing wear are reduced, particularly in the case ofdeviated wells. With lower rod stresses, surface drives canbe downsized, thus lowering capital and energy costs, anddownhole pumps can be upsized to provide increasedproduction. The absence of couplings also creates a moreuniform diameter, resulting in reduced pressure losses, alower likelihood of paraffin deposition and buildup and aless turbulent flow profile up the production tubing.

Reciprocating Pump

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 solidsin a vortex condition around each coupling increases therisk of abrasive coupling failure. In addition, the flowrestrictions created by the couplings decreases the pump'sability to effectively lift fluid/solids to surface.

The streamlined profile of Pro-Rod® coiled rod helps toenhance the operational efficiency of PCP systems byreducing rod and tubing wear as well overall rod stress.Lower rod stress allows the operator to downsize thesurface drive, thus lowering operating costs, or upsize thePC pump to increase flow rates to the surface. Thestreamlined profile of coiled rod enables laminar flow offluids to surface which minimizes problems associated withsolids fall-out. This profile also allows for coiled tubingclean-outs to remove solids down to the top of the pump.Additionally, without having to make-up a couplingconnectionevery25feet,Pro-Rod® strings areinstalled faster and with less manpower.

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 CHALLENGEReduce 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®wasinstalledinto1,500wells, initially as a pilot study. Due to the documented early success of the product and service model, the company electedtoconvert3,500producingwellsandinstallallnewdrills to Pro-Rod® coiled rod.

The service model warranted the deployment of 20Pro-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 RESULTSIn 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 improvedby33%,from9to12months.This represented significant savings due to a decrease in service costs.

The average time for the first intervention onanewwellwasimprovedby200%,from 3 to 9 months. This decrease in site downtime improved overall production by 10%,or258barrelspermonthperwell.
