PITTSBURGH — Chevron is putting on hold its plans for a large regional headquarters in the Pittsburgh suburbs.

The energy company has delayed a final decision on the office project for the foreseeable future.

The company, based in San Ramon, Calif., paid more than $17 million to buy land for what was envisioned as a 61-acre project.

Chevron is one of the region’s largest producers of natural gas from the Marcellus Shale formation, with holdings in Pennsylvania, Ohio and West Virginia.
