IRP 21 was sanctioned in May 2017, following a limited scope review. The key revisions include reformatting to match the current style guide, updated references, and most importantly, a revision of the Well Servicing Pressure Categories. These revisions align the IRP 21 Well Classification System with global API Standards.
