The engineering team at Bureau Veritas provides consulting services supporting all major aspects of drilling operations. Our dedicated and experienced engineers assist small independents to major operators around the globe to maximize the design of drill string structural integrity no matter the conditions.
To provide an optimal solution to your drilling needs, Bureau Veritas utilizes the expertise gained from thousands of engineering analyses. The comprehensive models have been used successfully in many of the worlds’ most technically challenging wells and, enhanced by customer feedback, resulted in concise and practical recommendations validated by experience.
When avoiding drill string structural failure can hinge on something as simple as connection selection, mechanical design represents an essential part of providing optimal solutions for complex drilling issues. Our in-house mechanical design group provides the extensive research and development which is needed to maintain our DS-1, and we perform evaluations of the design of all components for drilling operations, applying this expertise to
• Drill string structural design analysis – evaluating torque and drag with hydraulics as well as looking at the current rig inventory to determine the optimum design.
• BHA design and analysis – evaluating structural design of components to mitigate failures. Structural design of the bottom hole assembly typically includes review of weight on bit, stiffness, bending strength rations, connection selection, stability index, and buckling design factor.
• C-Fat Inspection Scheduling – based on the fatigue design approach that we developed for the 3rd edition of the DS-1. This can be used in planning, real time or end of job review to understand measurement of fatigue damage and how it accumulates so that a drill pipe inspection schedule is based on actual conditions rather than time.
• Landing string and slip crushing analysis – providing recommendations for landing string considerations appropriate to the wellbore design. This includes several considerations such as predicted loads, pipe physical properties, overpull analysis, connection selection, evaluation of traceability, and QA documentation of all components within the landing string.
• Heave induced dynamic load analysis – using proprietary methods we can determine the maximum sea swell that can be sustained by the drill string or landing string in floating rig operations.
• FEA and tool design review – examination of tool design to verify load ratings using finite element analysis.
• Casing wear analysis – using our in-house simulation programs, we can calculate the side loads for any operation and provide quantitative details of anticipated casing wear in each hole section.
• Stuck pipe analysis – providing an accurate trip profile with anticipated loads so that the driller has specific instructions on how to prevent stuck pipe. If pipe becomes stuck, Bureau Veritas can provide data on what tension, torque and loads can be applied.
• Failure analysis - The occurrence of any failure is unacceptable but, when one happens, it is vitally important to learn from it. We have performed thousands of failure analyses in the past 25 years. As industry leaders in engineering and quality assurance services, we will find the root cause of the failure and provide practical recommendations on how to avoid similar failures in future. The value of analyzing a failure correctly lies in not having to pay for it again.
With our experience analyzing drill string components, designing BHA and evaluating the factors that can lead to failure, Bureau Veritas is uniquely placed to provide recommendations on drilling operations that will lead to overall success, no matter the level of difficulty involved.
