This is probably the most important part of a casing crew’s job; identifying the pipe and ensuring all equipment and tools are within the specs to handle and make up the connections.
Why is this so important? The crew needs to understand what type of connections they are making up. Are they all the same, or are there different types in one string? This is crucial as torque figures might differ, connection OD and ID might change, or perhaps the connection is completely different and not compatible.
There are many ways to identify pipe and I shall try to outline how this process is done and what to look out for.
