so you got the mud logs which would tell you what all you drilled through to get to 18,00 feet?
Oil and or natural gas leaks (red and yellow columns) mapped by Thomas Jefferson, and by Gordon Gunter (purple cylinders) along with CTD stations showing high fluorescence or possible oil and gas anomalies (brown, green and white spheres). The Deepwater Horizon well site is in background (red cylinder) and distribution of Bottom Following Reflectors is represented by orange lines.
NOAA has said that the leaks on the sea floor graphed in the 3D model above appear to be pre-existing seeps that occur naturally and are unrelated to the spill and have labeled leaks as such in the Thomas Jefferson report.
Below is the well control loss time-line, and some recent seismic imaging done at the area of the well-head , from Alexander Higgins' blog
