Exploration and Development Well Information Network



The Bureau of Topographic & Geologic Survey launched the Exploration and Development Well Information Network (EDWIN) on September 23. Named in honor of “Colonel” Edwin L. Drake, who struck oil in Titusville on August 27, 1859, EDWIN provides users access to Pennsylvania’s 178,000+ oil and gas wells of record. EDWIN provides access to both scanned oil and gas well documents and associated digital and interpreted data through a single web-based application that stores database contents in the Cloud. EDWIN replaces the older PA*IRIS/WIS system, which was developed more than 20 years ago and provided well information using a combination of software applications and physical server infrastructure. 

System Access

EDWIN is accessible free of charge by visiting either of the Bureau’s offices (Pittsburgh or Middletown) during normal business hours. EDWIN is also available as a subscription service for those desiring the convenience of 24/7 remote access to Pennsylvania’s oil and gas well information. Any questions regarding EDWIN or obtaining oil and gas well data can be directed to the Bureau’s Pittsburgh office at 412-442-4235.
