Key benefits for your organization
Reliability under extreme conditions
Our Caterpillar products are designed for use in harsh conditions. The wellbore environment is often characterized by extreme temperatures, high pressure, and abrasive materials that would quickly wear out conventional equipment. Our Cat engines and gensets are built for longevity and durability, making them ideal for such demanding applications.
Performance and efficiency
The pumps used for re-cementing must generate extremely high pressures to push the cement into the wellbore. Our Cat engines provide the necessary power to operate reliably even under challenging conditions and high loads. This efficiency helps accelerate the cementing process and minimize downtime.
Compact and robust design
Our engines are compact and can be easily integrated into tight spaces on offshore rigs or mobile workover rigs. At the same time, their robust design withstands shocks, high vibrations, extreme temperatures, and corrosive environments, which are common during wellbore repairs.
Precision and control
Thanks to the advanced Cat control systems, our engines and pumps can be precisely managed, which is especially important to ensure that the cement is pumped into the correct areas. This precise control helps prevent leaks and restores the structural integrity of the wellbore.

Optimal cementing with Cat power
Re-cementing is a crucial step in wellbore repair to repair leaks or damaged cement barriers that are meant to prevent the escape of gas, oil, or water. Re-cementing is particularly necessary when the original cementing has been damaged by corrosion, deposits, or changes in the subsurface. By reintroducing cement into the affected areas, the tightness and stability of the wellbore can be restored.
Zeppelin Power Systems offers a range of Cat products that are essential for performing re-cementing operations in the oil and gas industry. Our products provide the necessary power and reliability to carry out demanding cementing projects, even under extreme conditions.
Cat products for demanding re-cementing operations
Our Cat C15, C18, C27, and C32 diesel engines deliver the required power to drive high-pressure pumps for cementing operations, where cement must be pumped into the wellbore at extremely high pressures. These engines enable the transportation of cement mixtures deep into the desired zones over several kilometers. The C18 engine is often used for cement pumps due to its high performance and compact design, while the C32 engine is ideal for particularly large cementing jobs that require high pressures and large flow rates. Both engines are designed for operation under extreme conditions, such as heat and pressure.
At remote locations, mobile gensets provide reliable power supply for wellbore repairs and re-cementing operations. These generators, specifically designed for use in the oil and gas industry, offer the flexibility to carry out cementing work even without fixed power infrastructure and are built to withstand challenging climatic conditions.

Effective leak management with Caterpillar products
While re-cementing uses fresh cement to stabilize the wellbore's steel casing, water ingress management focuses on repairing smaller leak points.
Sealing solutions for your wells
Sealing and water ingress management are key measures in wellbore repair to prevent the uncontrolled influx of water or gas into the wellbore. These issues can occur during production and impact the efficiency and safety of extraction. By using special sealing fluids or cement mixtures, leak points in the wellbore are sealed.
This method is particularly important when the original cementing has failed or when the wellbore needs to be adapted for new extraction methods.
Caterpillar power for the perfect wellbore condition
Here, our powerful Cat engines, such as the C15, C18, C27, and C32 models, come into play. They drive high-pressure pumps that generate the necessary pressure to inject sealing materials deep into the wellbore.

Mobile container solutions for wellbore repair drive systems
Flexible infrastructure for power supply in wellbore repair
Zeppelin Power Systems offers customized container solutions for the oil and gas industry, which prove essential in wellbore repairs. Since these repairs often take place in remote or extreme environments, the mobile and flexible containers provide optimal infrastructure for the safe and efficient operation of drive systems and power generation equipment.
With their ATEX certification, they are ideal for work in explosive environments, which are common during wellbore repairs, as these operations often involve gases and other hazardous materials. The container solutions, with their modular design, allow for quick transport and on-site assembly.
What technologies are used in workover operations?
Workover operations play a crucial role in the oil and gas industry, especially when it comes to restoring or increasing the productivity of a well.
Technologies used in workover operations
Specialized technologies and tools are required for workover operations to repair the wellbore. One central technology commonly used is coiled tubing. This is a continuous steel pipe wound on a drum that can be inserted into the wellbore without joints. Coiled tubing is used for various tasks, such as injecting chemicals, removing deposits, or sealing leaks.
Another important tool is wireline and slickline technologies. These thin, but extremely durable cables are lowered into the wellbore to deploy measurement instruments or tools. Wireline is often used to collect data about the wellbore's condition, while slickline is used for mechanical tasks such as installing or removing valves and other components.
Cementing involves pumping cement under pressure into leaking or damaged areas of the wellbore. This technique is commonly used to seal leaks in casing or stop unwanted fluid flows. The cement hardens and forms a barrier that restores the integrity of the wellbore.
Mixing and hydration units are used to create cement mixtures and chemical solutions on-site and pump them into the wellbore. They ensure that the correct chemical properties are available for the repair processes.
Drive systems and power supply for workover operations
Since wellbore repairs often take place in remote areas or under extreme conditions, the engines and generators driving the tools must not only be powerful but also robust and reliable.
For conducting workover operations, mobile power units are often required, which are flexible and portable to be deployed in hard-to-reach regions. These mobile solutions provide a reliable power supply and are specifically designed for operation in harsh environmental conditions.
Another key aspect of the drive systems for workovers is their power and efficiency. These engines must be capable of driving a variety of tools simultaneously without sacrificing efficiency. They often offer high power density to operate the required equipment safely and in a controlled manner. Modern diesel generators and electric motors are commonly used due to their reliability and ability to work continuously even under challenging conditions.
