BP's schills, pro BP scientists and industry experts have long denied the existence of the 3rd illegal well drilled by BP. Their strenuous denial is obvious since it was the 3rd illegal well that blew on 20 April 2010.

It was the only well that was drilled to TD (total depth of 18,360ft BSL) to reach the Macondo reservoir. The first 2 wells which were approved by MMS in BP's application was Well A and Well B which were drilled to depths of 5,000 ft BML and 13,300 ft BSL respectively. Both wells encountered shallow gas blowouts (out of well control situations, essentially the same as blowouts) and had to terminate drilling due to "jammed drill strings"on both holes. 

BP "misled" MMS by applying for a well by-pass each time they drilled a new well location. How could BP have drilled 2 by-passes from the same well A location which they had to abandon on 13 February 2010 under emergency near-disastrous situation?

If BP had not been able to drill beyond 5,000ft BML (10,000 ft BSL) at well A, how could they have managed to drill to 13,305 ft. BSL to report another "well control, pipe stuck and severed pipe at 12,146 ft event on 8 March 2010?

On 8 April 2010 (1 month later) BP reported another well control event. BP reported in their Well Activity report (WAR) "Macondo well Kick, initiation of reservoir fluids into the well bore due to an underbalanced condition occurred while drilling at a depth of 13,250 ft. Well Control event".

Is it not obvious BP had encountered enormous shallow gas problems from the GWSF hazards zone from 9,000 to 13,350 ft BSL? 

BP managed to contain the 8 April well event to continue drilling to reach the reservoir but not the other two well locations (A and B). There are many technical details to prove that BP drilled 3 wells. This evidence on the wellhead of the 3rd illegal is just one of the many.
