Pipeline right of way. Need legal guidance

We(multiple family owners) were recently offered a proposal from a landman that Denbury Resources wanted to construct a pipeline over a parcel of land in rural Calcasieu Parish south of Sulphur, LA. The proposal included a survey which showed an existing ethylene pipeline by a major oil company on the same area. None of my cousins nor I were aware of an agreement.
Thusfar I have not been able to locate a document confirming a ROW agreement with that company or even one in that section of land from the courthouse but I was able to locate some ROW agreements with the same ethylene (not too far away)line with other landowners. They were signed in 1984 and due to have been renewed in 1999. I did locate and visit the area and it appears that survey from Denbury resources indicates the pipeline is within the quarter section(our property) line there is correct. Last week I left messages with a contact number that the oil company gave me.
Are we entitled to tresspass damages if the pipeline was placed on the wrong property from possibly a survey error or construction mistake or other compensation?
It makes me recall what happened on Toledo Lake many years ago. A man that I know purchased land to build a camp. Six month later he discovered that all of the hardwood trees were cut down on his property. The tree cutters had gone to the wrong site and he sued for damages.
If the oil company fails to communicate with me in a reasonable time could a judge issue an order to block the line off at a metering station which 300 yards away? Dig up the line?
What options do the landowners have?

Could you recommend an attorney who specializes in oil and gas leases and tresspass law? Should we seek one? Need one now?

It would be greatly appreciated if anyone could point us in the right direction at this time.
