Narrative:
At FL370 on nat track we experienced significant wake turbulence from an aircraft that was 1;000 ft above and 13 NM ahead on the same track headed in the same direction. We contacted the other aircraft and asked him to offset to the right so that we could return to centerline (we were offset 2 NM right) and get out of the wake turbulence (winds were a quartering left tailwind and we were trying to get upwind of him). We could not descend as there was another aircraft 1;000 ft below us in close proximity. I suggested a left offset and after some discussion the other first officer agreed. We then offset 2 NM left of centerline (that put us out of the turbulence) until we passed the higher flight and returned to centerline. We then offset 2 NM right of course and continued to our destination. Right offset is standard and we should have coordinated with gander for a left 2 NM offset.
