Reliable Power Supply for ESP on Land and Under Water

A crucial component of any submersible pump installation is the cable, through which electricity is supplied to the well. Novomet has its own cable manufacturing facility, launched in 2021. This leads to a reduction in the cost of a complete installation, shorter production times, and guarantees timely product delivery.

"The cable was the last major product we were purchasing from outside, but after launching our own production, we ensured 100% manufacturing of all key components of complete installations," says Yuri Vinogradov, head of cable production at Novomet. "Today, we fully supply our branches both in Russia and abroad with cables. We use the most modern materials and maintain a high level of quality control. The reduced insulation layer significantly lightens the weight of the product, which is one of our competitive advantages in the market."

The submersible cable from Novomet is designed for powering submersible motors with a maximum operating voltage of up to 5000V AC and a frequency range from 50 to 400 Hz. Its applications include mechanized oil extraction, water injection into reservoirs, and intra-well pumping, as well as the operation of offshore fields, water intake wells, and geothermal wells.

The cable can be used both as part of an extension cord and for the main cable line in deep wells with complex characteristics—high temperatures of the surrounding working fluid, high water content, acids, salts, and other aggressive substances, increased intra-well hydrostatic pressure, and high gas factors. A wide range of sizes for cable extensions allows their use in any ESP from size 2A to size 9.

The special durability of the cable is achieved through a protective armor for various operating conditions, which reduces the number of failures when lowering installations into horizontal boreholes. The cable is resistant to temperatures ranging from -60 to +232°C. It can be manufactured according to individual parameters depending on the working environment conditions—corrosion-resistant designs, increased corrosion resistance, and resistance to stress corrosion cracking, particularly in especially challenging wells.

Higher reliability is ensured through the use of new heat-resistant electrical insulating materials, as well as through continuous improvement of the technological processes in their manufacturing.

Today, Novomet's production capacity is designed to produce 180 km of finished high-temperature submersible oil cables per month. The production lines are capable of manufacturing all sizes of submersible oil cables used for mechanized extraction. In the future, plans are in place to double the cable production capacity.

Universal downhole dosing unit – a universal assistant in the fight against salts and corrosion

Damage to submersible pump installations due to salt deposits and the carryover of insoluble solid particles from the reservoir remains one of the main factors complicating oil production. Novomet offers a comprehensive solution to this problem – the use of salt deposition inhibitors, filters (previously discussed here/link), and separators, as well as various design implementations.

"The formation of salts in the well occurs due to the supersaturation of water with poorly soluble salts when there are changes in temperature, pressure, pH levels, gas release, or mixing incompatible liquids. Salt is dangerous because it precipitates on equipment, mainly on pumps," explains Novomet process engineer Dmitry Savakov. "To protect against this, oil workers have several methods – physical, chemical, and technological. Today, the most effective method is chemical technology – the use of salt deposition inhibitors. They are introduced into the reservoir fluid and suppress the growth of salt and corrosion crystals. The best way to deliver them to the well is through containers installed beneath the submersible electric motor. Their advantages lie in the simplicity and convenience of installation and low operating costs."

The universal downhole dosing unit consists of a cylindrical body containing the inhibitor and a dispenser that controls the uniform flow of the mixture for at least a year. The technology operates without additional equipment and without human control, which enhances the efficiency of servicing wells in hard-to-reach areas. The location of the container at the bottom of the installation protects not only the pump but also all equipment, including safeguarding the motor from overheating.

A fundamental feature and advantage of the universal downhole dosing unit design is the placement of the dispenser on the container lid. This allows it to be used in simultaneous-separate operation when, due to the presence of a packer, it is not possible to dose the inhibitor from the surface.

The container is called universal because it can work with both solid and liquid fillings, as well as with chemistry against salt deposition and corrosion. Inhibitors in capsule form have become particularly widespread since their active base dissolves gradually rather than immediately. The design of the container for encapsulated inhibitors was proposed to reduce reagent consumption at the initial stage and to ensure a long-term stable supply of inhibitor into the reservoir fluid. This technology has undergone pilot industrial testing and has proven successful in operation with submersible electric pumps (ESP) at fields, with operational durations reaching up to 600 days or more. It can also be used in horizontal wells.

Thus, dosing units are installed in a single operation with the ESP, making them one of the most effective and economical solutions for preventing salt deposition and ensuring longer operation in the well.

ESP downhole disc filter – Reliable Protection for Long-Term Operation of Submersible Pumps

More than 60% of problems with submersible pumps arise due to the presence of solid mechanical impurities in reservoir fluids. They damage equipment, reduce production volumes, and incur additional maintenance and repair costs. The most common method of combating mechanical impurities has been the use of wedge filters; however, these devices are prone to rapid clogging and do not guarantee reliable protection for the installation.

Specialists from Novomet have developed a new volumetric device - ESP downhole disc filter. The design consists of a set of mesh rings mounted on a perforated shaft, which are manufactured using stamping. The size of the cells is chosen based on the required filtration fineness - 100, 200, 300, or 500 microns. The filtering element is made from corrosion-resistant material. The design of the filter is protected by a patent.

- The main advantage of the downhole disc filter is that filtration occurs not only on the surface but also inside the filter itself – in the mesh cells. In wedge filters, particles are retained only on the surface, allowing smaller clay particles to freely enter the pump and clog it, leading to faster blockage, - explains Yuri Korotkov, head of the design bureau for submersible pumps at Novomet. – At the same time, the downhole disc filter, providing high protection against mechanical impurities and extending the service life of the installation, wins in dimensions. Its length is 3-4 times shorter while maintaining the same necessary flow rates. Reducing metal consumption decreases weight and increases the overall resource of the submersible pump.

As a result of bench tests comparing clogging in wedge and disk filters of equal length with solid particle sizes of 0-200 microns, it was found that the throughput of the disk filter is 6-8 times higher. This is explained by the high specific area of open cells. The disk filter increases the service life of the submersible pump by 2-3 times, and in some cases even more.

The downhole disc filter easily performs its function in curved wells and in wells complicated by the carryover of mechanical impurities with an average particle diameter greater than 100 microns. It can be part of both compact submersible pumps of sizes 2A and 3 as well as the most common installations of sizes 5 and 5A. The downhole disc filter is mounted on a sealed casing or on the motor base (or Downhole ESP sensors) through a sealing unit.

To extend the service life of the submersible pump and ensure uninterrupted operation in the well, the filter can be equipped with a safety valve if necessary. This helps eliminate the risk of motor overheating during clogging of mesh disks. Additionally, one of the important advantages of the downhole disc filter is regeneration and multiple reuse. During scheduled maintenance or other instances when the installation is lifted to the surface, the filter can be cleaned and reused.

Overall, Novomet's downhole disc filter is currently the most successful and effective solution for protecting well pumps from mechanical impurities while maintaining reduced dimensional length and low hydraulic losses.

Rotary displacement cylindrical pumps - New Solutions for Extracting Heavy Viscous Liquids

Recent studies show that nearly half of the world's oil reserves consist of viscous and bituminous liquid deposits, with recovery rates ranging from 5% to 30%. Various technologies have been employed for its extraction, including cold production with mechanical admixtures, steam-assisted gravity drainage, open-pit development, and others. However, all of them are inefficient and create additional problems that reduce profitability.

Novomet has developed a solution unique to the market – a rotary displacement cylindrical pumps for extracting high-viscosity oil. This volumetric machine has become an excellent alternative to screw and rod pumping units, which significantly underperform in conditions of high mechanical impurities, gas content, and declining pressure. Additionally, the Rotary displacement pumps can replace electric submersible pumps (ESP) when operating at low flow rates (intermittent mode).

The configuration of the Rotary displacement pumps is similar to classic electric submersible pump systems, but compared to them, the Rotary displacement pumps eliminates operational interruptions caused by low inflow and high gas factors without additional pre-installed devices. It differs from screw pumps in that it uses components in its design that are resistant to aggressive environments, reducing wear and the likelihood of breakdowns. Advantages over rod pumps include a smaller footprint and dimensions, the ability to operate at depths of up to 3000 meters, no need for regular maintenance, and reduced risk of damage to sucker rods. Installation is standardized and does not require additional qualifications.

The volumetric rotary pump is designed for pumping liquids with a viscosity range from 20 to 5000 cSt. It is produced in sizes 5 and 5A. Its areas of application include wells with high-viscosity oil, low-flow wells, and wells complicated by mechanical impurities. It works excellently in wells with low inflow rates of 5-50 m³/day at temperatures up to 170°C. Moreover, the higher the viscosity of the oil, the better its efficiency, which increases extraction effectiveness without the need for complex and costly technologies.

"Today we are working on enhancing the uniqueness of our equipment and increasing the liquid pressure generated by each stage of the pump; we are conducting additional experimental tests," says Andrey Orlov, head of the design bureau for volumetric pumps and filtration systems at Novomet. "Increasing the pressure will reduce the number of stages and, consequently, the length of the pump, decrease material consumption and the risk of premature failure, as well as reduce power consumption per stage, which in turn will lower energy consumption."

Thus, the Rotary displacement pumps by Novomet is an entirely new pump design that provides excellent performance indicators such as output, efficiency, long service life under low flow conditions and heavy oil extraction, despite complications from mechanical impurities and high gas content.

SlimLine – the smallest installations for the most challenging wells

For cases where well operation involves lowering equipment into a «narrow» casing or navigating complex sections, such as transitioning from a larger diameter casing to a smaller one or lowering a pump into a lateral bore, Novomet offers a solution – the SlimLineESP equipment line in sizes 2A and 3.

SlimLineESP allows operation in lateral bores and production casings of 102 and 114 mm. These are small-sized electric submersible pumps (ESPs) with cross-sectional dimensions of 82 mm and 95 mm, respectively. Due to their compact size, they easily navigate complex curved sections, ensuring safe equipment lowering into the calculated suspension zone and trouble-free operation during the warranty period. SlimLineESP equipment can also be used as part of bypass systems like Y-tools in casings from 146 mm, where geophysical studies are required, and in dual systems for simultaneous-separate operation of multiple reservoirs.

The small-sized ESPs are powered by a high-speed valve motor of 81 mm on permanent magnets, which, combined with special algorithms from the control station, reduces energy losses. Novomet offers a wide range of valve motors, both single-section and two-section, with rated power from 20 to 200 kW. Additional equipment is used for protection against mechanical impurities – slotted and disc filters; to combat salt deposition – containers with inhibitors; and to manage gas – pre-installed devices (multiphase pumps, gas separators, gas stabilizers). Novomet specialists have developed a broad range of energy-efficient pre-installed devices for sizes 2A and 3, allowing reliable operation at speeds up to 8000 rpm.

Additionally, the company has developed a unique design of a volumetric action filter, which is more efficient than standard slotted filters. Its distinctive feature is that filtration from mechanical impurities occurs both on the surface of the filter itself and directly inside between the discs. As a result, it is shorter and, due to its unique design, more repairable. The filter is produced in size 81 – specifically for ESPs of sizes 2A and 3.

Overall, Novomet's SlimLineESP line is the most extensive on the market – with five sizes in 2A and six sizes in 3. The pump rotation speed ranges from 3000 to 6000 rpm. The average operational life is over 500 days, with more than 1,500 implementations for each size. Operational practice shows that this is a proven and reliable serial equipment today.

- A new improved model of the installation is currently under development with a motor rotation speed of 7200-8000 rpm, - reports Novomet's chief designer Konstantin Saveliev. - This will significantly reduce the length of the installation, making it possible to master wells with more curved sections.

Thus, Novomet's small-sized ESPs represent a new installation design with the widest range of pumps, valve motors, and pre-installed devices that ensure operation in challenging conditions with confirmed high reliability.

Geyser - Earth's Heat for Future Technologies

Geothermal energy is a highly promising field based on the use of hot water from the Earth's depths to generate energy, and it is considered the most stable among alternative energy sources. Currently, the majority of geothermal deposits consist of flowing wells, but reservoir pressure is rapidly declining, prompting consumers to seek solutions for mechanized extraction. Most submersible pumps either fail under high-temperature conditions or consume significant amounts of electricity.

To address the challenge of cost-effective operation of geothermal fields, specialists at Novomet have applied their extensive experience in the development and production of submersible electric centrifugal pumps, which has been proven reliable and effective in oil well operations. Now, this enhanced technology is applicable to even harsher, extreme conditions of geothermal water extraction, says Sergey Stolbov, Deputy Director of the Department of Innovative Developments at Novomet.

The Geyser systems for geothermal waters are equipped with heat-resistant components and filled with high-temperature motor oils. Additionally, they feature tandem hydraulic protection and two independent thrust bearings for increased reliability. The equipment can withstand temperatures up to 230 degrees Celsius, is resistant to aggressive environments, and can operate at depths of 1400 meters or more. The performance reaches up to 12,000 m³/day, with a service life exceeding a thousand days.

Renewable energy obtained from geothermal deposits is used for generating electricity at geothermal power plants or directly for heating and hot water supply, including greenhouse heating.

The Geyser technology not only ensures reliability but also significantly reduces energy consumption—resulting in a 25% savings in electricity. Consequently, this increases the service life and maintenance intervals while enhancing operational efficiency. Practical experience shows that the use of Geyser systems with a valve motor reduces specific energy consumption by up to two times for clients. Furthermore, the technology contributes to a decrease in CO2 emissions into the atmosphere.

In summary, high-performance geothermal pumping systems from Novomet provide reliable delivery of high-temperature formation fluids, feature a wide range of flow rates designed for operation under extreme temperatures, and ensure substantial energy savings, ultimately increasing the efficiency of electricity generation on the surface.

PowerSaveESP – A Complex Technology for Reducing Production Costs

Up to 61% of the energy consumed by a standard ESP system is lost to heating the fluid and equipment, with only 39% of the power used directly for hydrocarbon extraction. This is typical across the industry, and oil companies have long been working to reduce specific energy consumption. Various methods are employed, such as using high-voltage motors in the ESP systems, pumps with higher efficiency, changing equipment selection criteria, and others.

Novomet has taken a step further by creating the PowerSaveESP technology – energy- efficient installations. Its uniqueness lies in a complex approach that enables maximum reduction of oil extraction costs.

Firstly, it involves the proper selection in specialized software and operating equipment at maximum efficiency, which is ensured through special control station algorithms. Specialized software can define precise parameters for conditions and select an installation that will operate at the point of maximum efficiency.

Secondly, operation at high speeds (over 3000 RPM) has been researched at the company to determine the impact of rotational frequency on ESP efficiency. Tests confirmed that higher pump speeds lead to increased efficiency and head, allowing for a reduction in ESP length by up to 60%. An effective design simplifies installation, placement in wells, and replacement.

Thirdly, the installation incorporates pumps of a new design and valve electric motors. Energy-efficient pumps feature more complex, optimized geometries that reduce losses and increase stage efficiency by 10-15 points. A reinforced construction is used for operation at elevated rotational frequencies, ensuring necessary reliability. The advantages of valve motors are well-known – a wide range of regulation, lower losses, reduced heat generation, and consequently, higher efficiency.

Additionally, as part of the comprehensive approach to combat gas issues, solutions such as additional energy-efficient pre-installed devices – gas stabilizers and gas separators – are utilized. These devices are characterized by increased wear resistance and reduced energy consumption. The claimed specifications are confirmed by full resource testing and real-world operating conditions with clients.

All these solutions in total can reduce the energy consumption of ESP systems by 25- 30%, and in some cases, up to 35%. Furthermore, the pumps and motors included in the PowerSaveESP system manufactured by Novomet have a high energy efficiency class specified in their documentation and may qualify for various tax incentives. Novomet’s PowerSaveESP installations offer a very wide range, produced in sizes from 2A to 8 with flow rates ranging from 15 m³/day to 4000 m³/day.

- Thus, switching to energy-efficient ESP systems will reliably save up to 25% of electricity when lifting fluids from wells, - summarizes Novomet's Chief Designer Konstantin Saveliev. - It will enhance the reliability of submerged equipment, especially in challenging conditions, allow for stable operation at maximum efficiency or maximum extraction rates, and ultimately increase production volumes through effective selection.

Geyser High-Flow, High-Temp ESPs Deployed in Geothermal Wells in Turkey, Cut Electrical Usage by 28%

Geothermal power plants use water naturally heated by the earth to generate electricity. Geothermal energy is clean, renewable, and helps reduce carbon emissions related to power generation. But harsh conditions in geothermal wells cause many downhole pumps to fail prematurely. Typical geothermal well environments feature:

• Reservoir temperatures up to 200°С (392°F)
• Conditions prone to active scale accumulation

In 2018 and 2019, Novomet engineers used decades of knowledge and experience gained through deploying electrical submersible pumping (ESP) systems in harsh oil and gas wells to begin developing a cost-effective geothermal pumping system. This newly adapted geothermal ESP system featured heat-resistant, corrosion-resistant pumps and permanent magnet motors, which consume less electricity and produce less heat than downhole induction motors. Geothermal fields in Turkey provided the challenging conditions needed for Novomet to pilot its geothermal pumping systems. After initial development and lab simulations, Novomet engineers began installing and testing geothermal ESPs in wells across Turkey.

Novomet geothermal ESP systems performed well despite the harsh conditions. After seeing how successful the first systems were, Novomet began standardizing the design so it could be offered as a new line of pumps. Because of the massive volume of water required in geothermal operations, Novomet made additional design improvements, including high-volume, high-performance pumps and high-power permanent magnet motors. The result is the high-temperature, high-flow Geyser geothermal ESP.

In November 2019, three more Geyser geothermal ESPs were installed in Turkey. These systems have the ability to produce fluid at the rate of 10,000 m³/day (2.6 million gal/day) and they are powered by highly efficient 660-kW permanent magnet motors. These three systems are still running perfectly and bring the total count of Geyser ESP systems in operation in Turkey to 21. Despite geothermal fluid temperatures ranging from 155–195°C (311–383°F) Geyser systems have now been in operation for more than 380 days.

Because Novomet ESP designs are more efficient than competing systems, Geyser ESPs have also reduced the electricity required to pump a cubic meter of water in geothermal operations. The closest competing geothermal pump in Turkey uses 1.25 kWh per cubic meter of produced water, while Novomet Geyser systems consume only 0.9 kWh to lift the same volume of water. This reduces ongoing power consumption and costs by 28%, further supporting the goal of reducing carbon emissions.

Finding cost-effective, alternative energy sources remains a high priority for countries and companies alike in a joint effort to curb the increase in global average annual temperatures. Geyser ESP systems not only support sustainable geothermal energy initiatives to reduce greenhouse gas emissions, but they also reduce energy consumption by lowering the power required to produce geothermal fluids. Novomet is an active supporter of the Paris Agreement and is proud to join other technology-forward companies in the hunt for alternative, green energy solutions.
