Harris County is suing 10 oil or energy-related companies involved in the 2010 Deepwater Horizon disaster and Gulf of Mexico oil spill.
The group includes three British Petroleum companies, five Transocean companies and two Halliburton.
The lawsuit claims Harris County suffered damage in the form of lost revenue and other economic losses.
Some of the additional losses are related to lost hotel occupancy tax and personal property tax revenue.
Harris County is asking for a jury trial and is seeking a variety of damages and interest.
Harris County Attorney Vince Ryan estimates the damages could exceed $23 million plus interest.
The state of Texas and city of Houston have filed similar lawsuits in recent years.
