The careful introduction of cut inferences can be used to structure and possibly compress formal sequent calculus proofs. This paper presents CIRes, an algorithm for the introduction of atomic cuts based on various modifications and improvements of the CERes method, which was originally devised for efficient cut-elimination. It is also demonstrated that CIRes is capable of compressing proofs, and the amount of compression is shown to be exponential in the length of proofs.
