Breaking it Down: Engineering for Degradability in Industrial Applications

Temporary Materials Used in Oil and Gas Well Completions

There are a large number of applications of temporary materials in the process of completing oil and gas wells. Temporary materials are those materials that perform a function (usually mechanical) for a period of time downhole and then degrade and are removed without any intervention. The material can take many forms, from a mechanical component to fine powder depending on the application. A primary use generally involves influencing the flow path of fluids by creating a pressure tight seal. By using the self-removing materials, there is an opportunity for both cost savings and reducing the time and effort required to complete wells. Polylactic acid (PLA) is the predominant material used, but it has limitations. The advantages and disadvantages of PLA will be discussed, along with identifying where improvements are possible.

Don’t just take our word for it

I strongly recommend Innovation Takes Root. It's a good opportunity to understand and see what happens in this area of biopolymers. It's an international event and not just on PLA. I think it's well done, well-managed, and well-organized. It was a good investment for me.

I'd definitely come back (to ITR) and recommend it. I think many different industries could learn something from a conference like this - it really is focused on the next level of sustainability.

It has been a wonderful event; very well organized. I especially appreciate the scheduling of activities, the alternation of speeches, and time to network, which has been one of the key successes from my point of view. We also felt very supported by your team; we had the feeling you believe in what Flo is doing and, for us, that's very important.
