Methane Quantification at Extreme Distances

One of the hallmarks of lidar gas imaging is the ability to make high-resolution gas images at a great distance. The QLM camera can measure lidar returns out to ~200m and beyond. In recent testing with our partners at SLB, we maxed out (at 100m) the size of our test setup at the TTU Oilfield Technology Center; here are images of a 1kg/h leak at 100m range. The majority of US O&G facilities for example are far smaller than 200m in radius, so this is a demonstration of how one singular QLM camera can detect, precisely localize, and precisely quantify emissions at such a site from a central vantage point, out to ~200m radially. Note here that we are getting good lidar returns out to >225m, meaning we can measure plumes up to that distance if there is a hard surface at that distance to scatter back the lidar signal: The storage tank here is at ~105m but the field beyond is ~225m at its maximum distance. You can see bits of the plume (located at ~100m) which we detect via photons bouncing back from the ground >200m away, behind the plume.
