摘要: Downhole tools for use in oil and gas production which degrade into non-toxic materials, a method of making them methods using them. A frac ball bridge plug comprised polyglycolic acid can be used fracking well then left the bore to predictably, quickly, safely disintegrate environmentally friendly products without needing milled out or retrieved.
