... because of excessive gas encountered in the charged shallow water aquifer. The only remaining option was to drill a·relief well to control the blowout. PRE-PLANNING Relief Well 515 was to be drilled to kill the blowout flow in Well 159, plug and abandon Well 159, and then serve as a replacement well...
