Flare Stack Inspection While our drone contractor was collecting the baseline imagery (pre shothole), one of nearby field locations requested that we send our UAV contractor to with a flare stack inspection The flare was not safe to inspect without understanding the origin of the leak Utilized the quadcopter drone to inspect the full length of the stack in high resolution video Quickly determined the leak was confined to an area that could easily be fixed without risk 10

Thermal Test Flight in South Texas Oil Field 28,29.JAN.2017 Air Temperature ~45F Fluid temperature as high as 120F NYSE: DNR www.denbury.com 12
Thermal Test Flight in South Texas Oil Field 14
Timing now we know we have a tool that works but at the time we weren t sure about ground temperatures and variable near surface moisture content and how that might effect our results The plan was to start in S Texas when temperatures cooled off 45F ambient temperature and 120F fluid buried 3-4 feet Following the S Texas project, we would move up North We chose to wait until after the ground began to thaw worried about the insulated properties of the <32F near surface 45F ambient temperature and 200F fluid buried 6-8 feet 15
