There are nine keyfield indices that can be used to search for a desired file. The keyfield indices are: District, Lease/Gas ID, Docket #, County, Subject, Field Name, Lease Name, Applicant Name, and Hearing Date.  Key the information you are looking for into the appropriate value box.  Generally, less information will provide a better search result.  For example, if you know the docket number of the hearing you are interested in, that is the only value box you need to populate.

Wildcard Feature

To the right of each Value box there is information describing the requirements.  Several Fields allow the use of the wildcard ( asterisk icon for wildcard ) feature.  Use the asterisk (*) when you are unsure of the spelling of a name or when you would like to see records for all formations of a field:

texas Returns results where 'texas' has to be an exact match for the Value
