If someone decided to take a really long time with all their procedures and continue straight out, they could go quite far. There are some locations with distant mountains as we all know.
While the published departure procedure doesn't necessarily meet engine-inoperative criteria, I have found some info about normal departures....
What criteria is used to provide obstruction clearance during departure?
The 40:1 obstacle identification surface (OIS) begins at the departure end of runway (DER) and slopes upward at 152 FPNM until reaching the minimum IFR altitude or entering the en route structure. This assessment area is limited to 25 NM from the airport in non-mountainous areas and 46 NM in designated mountainous areas. Beyond this distance, the pilot is responsible for obstacle clearance if not operating on a published route, if below (having not reached) the MEA or MOCA of a published route, or an ATC assigned altitude.

I wonder what it is for engine out procedures?
