RE: RE: RE: From SOUND this am I think that we have to assume that they are working at drilling towards TD. TD can be anywhere that a decision is made to cease drilling and TD is not necessarily the projected TD as per the drilling program.
I am guessing that the current hole size is causing problems with deviation issues and drilling is slow, key word being "guessing". This comes with the idea that the drill collars are not fitted with stabilizers and perhaps in the interests of preventing any further stuck drill strings in the hole I also assume that formation pressures between the two zones of interest have been considered and are not an issue.
