Lawsuit allegations            

In the lawsuit, eight plaintiffs have sued 25 defendants, alleging that they own and/or use a certain 4,480 acres located in the Pointe a la Hache oil and gas field.

In the lawsuit, the plaintiffs have alleged that real property they own in Terrebonne Parish has been environmentally damaged as a result of oil and gas exploration activities of twenty different defendants.  The plaintiffs seek damages for testing and remediation of the property, property stigma, loss of use of land and lost profits, civil fruits for defendants trespass, land loss and subsidence, punitive or exemplary damages and attorney’s fees. Per Louisiana law, no actual dollar amount of damages has been alleged in the Petition. With specific regard to HKN, Inc., out of over one hundred wells identified in the Petition, HKN, Inc. only drilled one well, the MA Smythe Nelson #1, which was a dry hole. The MA Smythe Nelson #1 was drilled on June 2, 1980 and plugged and abandoned on July 12, 1980.

Plaintiffs South Louisiana Flood Protection Authority—East (“SLFPA-E”) filed this lawsuit in Louisiana state court against over 90 oil and gas and pipeline companies. Generally the lawsuit alleges that activities by defendants—primarily but not exclusively the dredging of canals—have made it more difficult for the SLFPA-E to protect the New Orleans metropolitan area from flooding.
