The Pennsylvania Independent Oil & Gas Association (PIOGA) has appointed Daniel J. Weaver president and executive director. Weaver succeeds Louis D'Amico, who after 22 years in the position has announced his retirement. Weaver, 37, has served as PIOGA's public outreach director since 2012 and previously held several leadership positions with the Drake Well Museum in Northwest Pennsylvania, which is the site of one of the nation's first commercial oil wells. D'Amico has been a vocal proponent of the state's oil and gas industry, especially in recent years as it faced closer scrutiny with the rise of the Marcellus Shale. "He has been at the forefront of every issue faced by our members during his tenure with this organization and its predecessor," said PIOGA Board Chairman Gary Slagel. D'Amico will retire after working for 44 years in the industry. Based in Western Pennsylvania, PIOGA represents 550 members working across the state's oil and gas industry.
