Almost one month after a fiery oil rig explosion in Karnes county, Encana Corp released final figures to state regulators.

Encana Corp. reported that the accident released over 760,000 pounds of crude oil and possibly tens of thousands of pounds of gas and into the air. The company estimates that the crude was worth more than $197,000.

The county sheriff called the May 19th accident the ‘worst environmental disaster in more than 20 years’, leaving trees, fields, roads and houses covered in oil and displacing numerous families.
