Figure 1. Map showing wells that were drilled through the allochthonous salt, as of 1995. To date (1995), 27 wells have been drilled through the allochthonous salt since 1984 (red dots). The first discovery was in Mississippi Canyon 211 by Exxon in 1990. This well was in water over 4300 ft deep - on the slope. The Mahogany well also discovered hydrocarbons below salt, but the water depth is significantly shallower (372 ft) - on the shelf. In 1994 Phillips and Anadarko also announced the Teak subsalt oil discovery in 290 ft of water. Currently three significant subsalt wells are operating, two exploration and one delineation.
