Summary

In the high-stakes world of oil and gas well construction, the integrity of tubular components is not just an engineering metric—it is the foundation of operational safety and commercial success. Engineers face immense pressure to design casing, tubing, and downhole equipment that can survive extreme downhole conditions, including high pressure, high temperature, and dynamic mechanical loads, over the service life of a well.

This is where the TDAS Tubular Design and Analysis System (TDAS) proves invaluable. Since 1985, this software has served as a trusted digital solution, enabling engineers to simulate complex operating conditions, anticipate potential failures, and define secure operating envelopes. By automating critical calculations and providing data-driven insights, TDAS empowers professionals to transform complex engineering challenges into confident, optimized well designs.

What is TDAS Tubular Design and Analysis System Software?

TDAS is a specialized engineering software application developed by SLB (formerly Schlumberger) for the analysis and design of casing and tubing strings. It is a critical tool in the well completions digital solutions portfolio, designed to ensure the integrity of downhole equipment throughout a well’s lifecycle.

Target users include:

• Petroleum and Completion Engineers

• Drilling Engineers

• Well Integrity Specialists

• Technical Professionals involved in well planning and operations

Key Features & Benefits

TDAS provides a comprehensive suite of analysis tools that help engineers move beyond guesswork to data-backed decision-making:

• 01. Stress & Movement Analysis: An accurate engine calculates stress and movement for downhole tubulars and equipment, ensuring integrity during installation, production, and beyond.

• 02. Torque & Drag Simulation: The software simulates whether a tubular string can safely reach the target depth, preventing costly and dangerous operational issues.

• 03. Thermal & APB Analysis: It simulates multi-string temperature profiles and annular pressure buildup (APB) caused by temperature changes during production or injection, mitigating risks of burst or collapse.

• 04. Least Cost Design Engine: This feature automatically proposes minimum-cost string designs based on user-defined constraints, optimizing both safety and budget.

• 05. Risk Warning Outputs: The software delivers a clear output summary with integrated warnings for potential hazards like pipe buckling and burst, allowing engineers to proactively address issues.

Pricing & Plans

While TDAS is typically offered through enterprise licensing due to its specialized nature, SLB provides flexible access options:

• Free Trial / Demo Access: Qualified professionals can often request a free trial or guided demo access to evaluate the official version of the software. This allows you to test its capabilities against real-world well scenarios before any commitment.

• Premium Plans: For long-term deployment, SLB offers premium plans tailored to company-wide or multi-user team requirements. These plans include full technical support and regular updates.

• Special Offers: Contact SLB sales to inquire about potential promotions, including up to 50% OFF for qualifying educational institutions or long-term enterprise contracts.

Use Cases: Real-World Applications

TDAS is not just theoretical; it solves tangible problems. A notable case study involves the Kuwait Oil Company (KOC), which used TDAS to design a dual-concentric completion for an Electrical Submersible Pump (ESP) system. This application enabled KOC to simultaneously produce oil and inject water, saving at least USD 4 million. Other typical use cases include:

• Designing casing programs for high-pressure, high-temperature (HP/HT) wells.

• Verifying the integrity of tubing strings for deepwater completions.

• Analyzing thermal stresses in steam injection wells for heavy oil recovery.

Who Should Use This Software?

• Beginners: New engineers will find the user-friendly workflow and flexible, predefined load cases accelerate their learning curve, reducing the risk of errors.

• Professionals: Experienced well design experts can leverage advanced features like the kick tolerance calculator and least-cost design engine to optimize complex multi-string designs.

• Agencies & Consultants: Engineering firms will value the software’s adherence to industry standards such as API Specification 5CT, Specification 11D, TR 5C3, and Specification 19V, ensuring their designs are legally and technically sound.

When NOT to Use This Software

While powerful, TDAS is a specialized tool. It is not designed for:

• General-purpose CAD modeling: For creating detailed 3D models of rig equipment, use general-purpose CAD software.

• Surface facility design: The software is focused on downhole tubulars, not surface pipelines or processing plants.

• Teams without well engineering expertise: Effective use requires a fundamental understanding of well mechanics, loads, and design criteria.

TDAS vs Competitors

When evaluating well tubular design software, several key differences set TDAS apart:

• TDAS by SLB vs Oliasoft WellDesign: Oliasoft offers a modern, web-based platform that unifies trajectory, casing, tubing, and drilling mechanics. TDAS, while traditionally a desktop application, benefits from deep integration into the SLB ecosystem and a proven 35+ year track record of reliability in major operating companies.

• TDAS vs WELLCAT: WELLCAT is another robust tool, particularly strong in modeling complex HP/HT conditions and steam injection scenarios. TDAS differentiates itself with its “least cost design engine” and a more streamlined workflow for standard completion types, which can save significant time in conventional well planning.

• TDAS vs WellPlan: Halliburton’s WellPlan is a comprehensive well engineering tool kit covering hydraulics, swab/surge, and well control. TDAS excels specifically in tubular stress and movement analysis. The choice often depends on which broader ecosystem (SLB or Halliburton) your organization primarily uses.

System Requirements

How to Use TDAS (Step-by-Step Workflow)

1. Define Well Parameters: Input well trajectory, depth, and hole size.

2. Select Tubulars: Choose casing, tubing, and completion equipment from the library or define custom specifications.

3. Apply Load Cases: Use predefined or create custom load cases for installation, production, injection, and testing scenarios.

4. Run Analysis: Execute the stress, movement, torque, and drag simulations.

5. Review Output: Analyze results, risk warnings, and the least-cost design proposal to finalize a safe and optimized plan.

Pros and Cons

Pros:

• Industry Standard: Trusted by major operators globally since 1985.

• Comprehensive Analysis: Combines stress, movement, thermal, APB, and torque/drag in one tool.
