The EXCELLENT Artificial Lift Technology for YOUR application!
The industry nowadays offers countless artificial lift systems, from standard to very special. But not everything what is available, is really necessary and reasonable. And vice versa, not everything what is desired, is already available…
As independent partner we are happy to find the right AL system for you. This may be a proven standard system from stock, a customized system for your special application, or a tailor made system, which is specifically developed for you!
You can find here some of our favourite Artificial Lift technologies – from standard to quite special applications:
- Piston Pumps

- PCP – Progressive Cavity Pumps
- PMM Motor
- GL – Gas Lift
- Others
Rod Pumps
How we can support you:
Despite the simplicity of a standard SRP, even more important is high quality of every single part. Especially barrel, plunger and valves need to be in perfect shape in order to facilitate a long run life in your wells. Professional factory acceptance tests according to API 11AX are cumbersome to prepare and execute - let us support you in this matter!
Due to their application in low rate - low budget fields, SRP got a cheap image in the industry. However, especially under these economic conditions, long run lives and avoiding workovers and buying new pumps are so important for your field economics!
But we can do so much more - from detailed failure analysis we can develop tailor made solutions, design adaptations and quality assurance plans for you. We are looking at the bigger picture - quality and design of pumps, the rod string and pumping unit, the operating environment and procedures - all to find a way to produce more, longer, better.
In addition we know countless special parts offered in order to tackle specific challenges of your SRPs - eg gas/sand production and crooked holes. We are also open to support you in designing new special parts, deviations from API 11AX, wherever necessary.

Hydraulic Long Stroke Rod Pump
How we can support you:
The surface pumping unit of standard SRPs is usually looked at just twice - at design and first installation. We are looking at pumping units in much more detail and with dedication, especially at hydraulic long stroke units:
To use the whole potential of hydraulic long stroke units, it needs some careful design of its installation and operation. Especially the smart operation control of the hydraulic drive is a key task on the system's overall efficiency. Needless to say that digitalization of the pumping unit operation represents a great asset for increasing the efficiency of this artificial lift method.
In addition we care for your downhole pump parts as usual - we know each downhole pump part by heart and look for optimization of downhole pump, tubing and rod string.

Heavy oil ESP
How we can support you:
Our team has extensive knowledge in ESP applications for heavy oil fields (up to 1000 cP dry viscosity). In some fields it may be necessary to execute detailed test programs in special ESP pump test stands, to fully reflect the impact of your oil on the pump stages. Of course we are ready to support you with preparation, execution and analysis of these pump tests. With the knowledge about the derating of the system due to viscosity, we can adapt the ESP design, making it fit for purpose in your heavy oil field.

Polymer Backproducing ESP
How we can support you:
In some chemically flooded fields, Electrical Submersible Pumps are selected to back produce the injected polymer solution. Depending the reservoir conditions, this solution may have even initial fluid properties and therefore can represent a challenge for the pump. Since ESPs are sensitive to changes in production environment, their design needs to be carefully harmonized with the expected properties of back produced fluids over time.
Our team is supporting you also here along the whole lifecycle - from the first entry of polymer solution into the borehole until it reaches the separator. We are familiar with typical production challenges of various polymer floods around the world and what it needs to design and operate a resilient polymer back producing ESP.

Gas Hydrate Production with ESP
How we can support you:
In this application we set the focus for the ESP on a gassy fluid ESP design on the one side, as well specifically on the accurate drawdown control of the system on the other side. It is crucial to carefully operate the ESP system in order to balance the required dissociation pressure without pumping off. Our team is very experienced in setting up system controls to make your operators' life easier in that respect. We are experts in automation, thus building automatic alarms and reacting on changing fluid properties into the control system is one topic we can help you with.

ESPs for high GOR wells
How we can support you:
There are several approaches to adapt ESP designs to gassy fluids. The application of flow diverting pods, adapting pump setting depths, but of course also numerous special parts (gas separators, booster stages), may help to qualify your ESP system for gassy wells. Our team is supporting you in analyzing the impact severity of free gas on the ESPs over time and recommends the best economic technology for your application.

ESP for DST
How we can support you:
Of course this non-standard application requires careful ESP design to qualify the parts for the shock wave resulting from the perforation. In most cases the ESP is supposed to produce only for short time period to gather production and pressure data of the open interval. Therefore, our main focus is on the materials and pressure ratings of all string parts, rather than on long lasting ESP.

Coiled Tubing deployed ESP
How we can support you:
Keeping an overview of already available rigless ESP systems takes time - analyzing which system is of most value for your fields even more: technologies and deployment methods, available pump sizes, materials and ratings, service availability, operating flexibility for the pumps' lifetime, installation programs, etc. As independent experts, we are supporting you in technology selection and ESP design from idea to execution.

Dual ESP
How we can support you:
Parallel Back-up ESP: Dual ESPs in parallel set-up can be used to add redundancy to the ESP string. Even though the lifetime of the AL method is not double, at least some production can be achieved with the back-up ESP, once the main ESP has failed. Therefore dual ESP systems can significantly reduce deferred production during the waiting for workover rig. Our team is supporting at designing both ESPs with special focus on material selection and operational procedures, to make sure the back-up ESP is successfully working whenever necessary.
Parallel commingled Dual ESP: Dual ESPs can also be used for highly controlled production of two reservoirs with different pressure and productivity. In this set-up the ESPs are balancing the inflow characteristics and produce either commingled or one-zone at a time to surface. We are very experienced in flow modelling for this very specific application, especially finding the optimal design combination for your reservoirs!
Parallel concentric Dual ESP: Another parallel application is the independent Dual ESP with dual concentric tubing strings to produce separately from two different reservoir sections without mixing the reservoir fluids. Here our focus lays in selection of pump and string dimensions, to facilitate having two strings at once in your well.
Serial dual ESPs: This set-up is used when large heads need to be produced. There, the lower pump acts like a booster pump, increasing the inlet pressure of the upper pump. This application requires right selection of parts, tolerating strong pressure fluctuations - we are happy to support you with this design!

High speed slim ESP
How we can support you:
Our team actively follows technology development of high speed ESPs for the application in smaller diameter casings. Also here we are following our approach of sandface-to-separator service: From early design phase until execution and production optimization, we are caring for your system. We are accounting especially for changing reservoir parameters over time, making your ESP system as flexible as possible and resistant against potential flowback of proppant.

Ultra-high speed ESP
In wells with small casing diameters, one way to reach high production rates is to increase the frequency of the driving system. Also for retrofit applications in existing tubings, ultra-high speed ESPs can deliver reasonably high production rates. This application is usually equipped with permanent magnet motor, which reaches up to 10.000 rpm.
ESP controlled Dump Flood
How we can support you:
Here the ESP performance is depending on both productivity of the production zone and injectivity of the injection zone, which both may change over the pump's life time. This application requires a lot of modelling experience to get the ESP system design right at the first time. In addition the ESP can be installed in different ways - depending on where the ESP is landed, it can be executed with inverted ESP systems or including a pod /encapsulation. Your prudent knowledge about the productivity and injectivity of both layers build the fundament of our complex application design.

Geothermal ESP
How we can support you:
Usually geothermal applications need high production rates to generate economic heat output. There, special attention should be paid on motor and seal section. In order to withstand high temperatures, we are reviewing design and material selection in detail. In addition, we account for solid content, naturally occuring radioactivity, scaling tendency and corrosivity of the produced hot water. Our team is supporting you in selecting the right ESP system and reasonable operating ranges for your geothermal wells. Increasing your geothermal project economics, our focus lays on long run life and stable high rate production.

SAGD ESP
How we can support you:
Our team is supporting you during the whole thermal EOR project. We are able to recommend necessary adaptations in the design phase, addressing reservoir uncertainties and technical requirements. For SAGD ESPs of course we are focusing on the influence of temperature (250°C) and gassy low viscosity fluids on all system components - especially elastomers, motor insulation, bearings and shaft seals.

PCP - Progressive Cavity Pumps
How we can support you:
Though PCPs consists only of few parts, proper design is even more important. We support you at finding the right PCP for your application, select the best elastomer for your stator, assist at installation and data interpretation and of course are there for pump disassebly and failure assessment.
ESPCP
At Electrical Submersible Progressive Cavity Pumps, a downhole motor is turning the rotor of the PCP. By replacing the standard rod drive, the ESPCP becomes more resilient for larger depths and deviated holes, but still keeps the advantages of the pumping action of the PCP.
SAGD Metal to Metal PCP
Whenever the efficient pumping action of PCP is desired, but the fluid conditions (high T, varying fluid composition), the M2M PCP is a good alternative. Here the seal face of the stator is not a vulnerable elastomer, but hard steel.
PMM Motor
How we can support you:
To harvest the whole potential benefits from permanent magnet motors, we are supporting you at design and operating procedures for your specific application.
The higher energy density offers shorter and lighter ESP strings - especially interesting for highly deviated, deep and unconventional wells. The lower motor heat generation elongates the overal run life, helps in high T reservoirs and avoids undesired fluid precipiation effects on the housing. Especially the application of slimhole high speed PMM may turn many challenging wells into success!

GL - Gas Lift
How we can support you:
The perfect (flexible, maintenance free, reliable and resistant) Gas Lift design is considered an art for many engineers. Many years of experience may be necessary to find the best set-up of different valve types, setting depths, and operating pressures. We support you at the selection of the right GL method, initial design, installation and operating procedures. Interpretation of GL charts belongs as well to our favourites, as the production optimization simulations of whole gas lifted fields, to get the most oil of your available lift gas.
Gas Lift HPHT
For the application of Gas Lift in high pressure high temperature wells, a lot of attention must be paid on the fluid behavior at these harsh conditions. Once lift gas is pressured so much that it becomes a supercritical fluid, valve design and flow assurance need to be re-engineered totally in order to reach a reliable and efficient injection operation.
Gas Lift electrically activated
Gas lift systems are highly dependent on good input data and build on the premise that the production environment stays constant. Since reservoir pressure, fluid composition and desired flow rates may change with time, a more flexible gas lift system is required. By using an electrically activated GLV, the necessary exchange of the valves is made redundant. Similar to inflow control valves, now the gas lift valves can be electrically adjusted and optimized based on the current conditions.

We assist you not only with the design of the jet pump, but also make recommendations how to apply chemical solutions for your challenging field application - and this in a safe, reliable and efficient way!
HSP Hydraulic Submersible Pump
Hydraulic Submersible Pumps are similar to standard ESPs, but are driven not by an submerged motor, but by a pressurized power fluid and a turbine. Thereby all potential failures of electrification (cable, motor, protector) are avoided, but also any problems arising from high temperature of the motor. Furthermore HSPs can operate at larger rotational speed than standard ESPs and are able to handle significant amount of free gas at intake. In an open design, the power fluid is commingled with the reservoir fluid after the centrifugal pump and needs to be separated again on surface. When being pumped in a closed system, more effort needs to be taken for the system design itself.
HPS Horizontal Pump System
Horizontal Pump Systems are centrifugal booster pumps, most often used on surface or platforms to for crude oil transport pipelines, or in subsea skids to boost the fluid on the seabed.
Multiphase Pumps
Subsea multiphase pumps can bring significant value by lowering the well head pressure and thereby increasing recoverable reserves of low pressure wells. In addition the multiphase pumps boost the produced fluids on the seabed to reach the processing facilities.
Downhole Water Separation
Downhole oil/water separation offers large benefits, once the system is properly designed: Here typically an ESP is producing oil and water of a conventional reservoir, feeding into hydrocyclones, which separate the water from the produced oil. The water stream is getting reinjected into a water zone, while the oil stream is produced to surface.
Downhole Gas Compressor
Similar to ESPs in oil wells, downhole gas compressors are used in wells of midlife gas fields, in order to increase the recoverable production of lower pressure gas wells. Magnetic couplings are connecting the Permanent Magnet Motor with the Gas Compressor section, making drive shafts and seal sections redundant, thereby increasing the system's reliability.
The electric light did not come from the continuous improvement of candles.
