Pretty drawn out saga the Heron drill. Seemed to be done in two parts the Plover formation and then moved on to Epenarra.
The West Atlas was then moved on to drill Blackwood. I didn't include Blackwood on there - not enough room(spudded 01/02/2008)
The West Atlas went on to have a undistinguished career (or should that be an unextinguished career?), culminating in this mess.
