Oil production history

Is there anyone who would know where I could get information on the oil production (BBL) for a specific area/wells going back to 1986? None of my family (rightful mineral heirs) was notified of these producing wells so don't know if royalties were pooled/held or forfeited to the state. Thank you in advance for any HELP!!!

The TX RRC's Production Data Query goes back to 1993. Getting records before that would likely involve an open records request or something similar. http://webapps2.rrc.state.tx.us/EWA/ewaPdqMain.do

Thanks so much AJ!!
