Fiberglass Sucker Rods vs Steel Sucker Rods: Which One is Better for Your Well?

In the oil and gas industry, the efficiency of well operations significantly depends on the type of sucker rods used. As a leader in providing cutting-edge solutions, CNPS offers expert guidance in this critical area, including the utilization of advanced products like API 15hr pipes.

Sucker rods are crucial in the artificial lift system, and choosing between fiberglass and steel sucker rods can have profound implications on operation costs, maintenance, and overall productivity.

This blog aims to provide a detailed comparison between fiberglass sucker rods and steel sucker rods, helping industry professionals make informed decisions for enhanced well performance. For personalized advice and solutions, our CNPS specialists are readily available to assist you.

Understanding Sucker Rods

Sucker rods are essential in the artificial lift system, a method used in oil wells to increase pressure within the reservoir and push the oil to the surface. These rods connect the surface and downhole components of a pump in an oil well. The material composition of sucker rods is crucial as it directly impacts their ability to withstand daily stresses and environmental factors within the well.

Their performance, durability, and compatibility with specific well conditions are vital considerations in the selection process. In particular, considerations of reinforced thermoplastic pipes (RTP pipes) are gaining attention for their durability and resistance in certain applications.

In addition to material considerations, the design and manufacturing quality of sucker rods play a significant role in their performance. The right choice of sucker rods ensures efficient energy transfer, optimal pumping speeds, and reduced downtime, all contributing to the overall cost-effectiveness of well operations.

Fiberglass Sucker Rods: Innovation in Artificial Lift

Fiberglass sucker rods.

Fiberglass sucker rods are a modern solution to some of the challenges posed by traditional steel rods. These rods are engineered for performance and longevity, with several key benefits:

  1. Enhanced Corrosion Resistance: In environments with high levels of H2S, CO2, or saline water, steel rods are prone to corrosion, leading to premature failure. Fiberglass, with its inert properties, withstands these harsh conditions, reducing the frequency of maintenance and replacement. This resistance is similar to the qualities found in fiberglass pipes and tanks, which are also known for their durability in corrosive environments.
  2. Optimal for Moderate Depths: While fiberglass rods are not typically used in extremely deep wells, they are ideal for moderate depths, providing sufficient strength while offering the benefits of lighter weight and flexibility.
  3. Reduced Rod and Tubing Wear: The elasticity of fiberglass reduces the pounding effect on the tubing and rod, minimizing the wear and tear that is often seen with steel rods. This extends the life of both the rods and the tubing.
  4. Increased Pump Efficiency: The lightweight nature of fiberglass rods allows for more efficient energy transfer during the pumping process, which can lead to increased overall pump efficiency.

Steel Sucker Rods: The Traditional Standard

Steel sucker rods have been the standard in the industry for many years. Known for their strength and durability, they are often preferred for certain types of wells. For instance, in wells where GRE tubing is used for its corrosion resistance, steel sucker rods can be a compatible choice due to their robustness and ability to handle similar operating conditions.

  1. Suitable for Harsh Environments: Steel rods are often preferred in wells with abrasive elements, where the robustness of steel is necessary to withstand the harsh downhole conditions.
  2. Versatility in Application: Steel rods can be used in a wide range of well depths and conditions, making them a versatile choice for many oil and gas operations.
  3. High Load Capacity: For wells that require heavy lifting capacity, steel sucker rods provide the necessary strength to handle the significant loads associated with deep and high-volume wells.
  4. Long-Term Cost Benefits: While the initial investment in steel rods might be higher due to potential corrosion issues and the need for more frequent replacements in certain environments, in wells where corrosion is less of a concern, their durability and strength can offer long-term cost benefits.

Comparative Analysis

When comparing fiberglass and steel sucker rods, it’s important to understand how their distinct characteristics can influence well operations.

  1. Well Depth and Load:
    • Steel Sucker Rods: For deep wells, especially those exceeding 2,500 meters, steel rods are often indispensable. Their ability to handle significant axial loads without compromising integrity makes them a reliable choice for such demanding environments. In such cases, complementing the system with GRE tubing can enhance the overall efficiency and durability of the setup.
    • Fiberglass Sucker Rods: Ideal for wells up to approximately 1,800 meters deep, fiberglass rods are beneficial in scenarios where load requirements are moderate. Their usage reduces the overall weight of the rod string, easing the burden on the lift system, and can be effectively integrated with fiberglass reinforced plastic pipes for a cohesive system design.
  2. Corrosive Environments:
    • Advantage of Fiberglass: In wells with high acidity or the presence of corrosive gases like hydrogen sulfide, fiberglass rods exhibit remarkable resilience, similar to that of FRP pipes, known for their corrosion resistance. They do not succumb to the rust and corrosion that typically affect steel rods, thereby enhancing well integrity and reducing the risk of environmental hazards.
    • Coatings and Alloys for Steel: To combat corrosion in steel rods, the industry has developed special coatings and alloys. However, these solutions can be cost-prohibitive and may not always provide long-term protection, unlike integrated solutions such as GRE casing, which offers inherent corrosion resistance.
  3. Long-Term Operational Costs:
    • Maintenance and Replacement Costs: The durability of fiberglass reduces the frequency of rod replacements and maintenance interventions. This can lead to significant savings over the life of the well, particularly in corrosive environments.
    • Energy Efficiency: The lighter weight of fiberglass rods translates into lower energy requirements for the pumping unit, which can be a critical factor in reducing operational costs, especially in remote or energy-sensitive locations.
  4. Environmental and Safety Considerations:
    • Reduced Environmental Impact: Fiberglass rods contribute to a smaller carbon footprint, both in terms of manufacturing and operational energy use.
    • Safer Handling and Installation: The lightweight nature of fiberglass rods reduces transport and handling costs and minimizes the risk of injuries during manual handling and installation processes.

Choosing the Right Material for Your Well

Selecting the appropriate material for sucker rods requires a holistic approach:

  • Assessment of Well Characteristics: Parameters such as well depth, temperature, presence of corrosive fluids, and the type of production (oil or water-heavy) should be evaluated. In this context, understanding the application of reinforced thermoplastic pipes (RTP pipe) alongside sucker rods can be crucial for certain well environments.
  • Economic Analysis: An economic analysis considering both the short-term and long-term costs associated with each type of rod is critical. This analysis should include initial purchase costs, expected lifespan, maintenance requirements, and any additional operational costs. For wells requiring enhanced corrosion resistance, incorporating GRE tubing as part of the overall system may also be a factor in the economic analysis.
