The DT-4 well is being drilled vertically to an estimated target depth of 2,020m with the principal objective of testing a four-way fold closure that is part of a fault block prospect named Davsan Tolgoi West, that has a pre-drill potential mean un-risked resource of 21mmbo.
DT-4 is being drilled by a partially winterized rig and is currently at a depth of 1,271m, at the bottom of the intermediate section.
The well has been logged to the current depth, the casing and cementing of the intermediate section has been completed, the wellbore is in a safe position and the reservoir section is yet to be disturbed.
The drilling rig will remain on location and is being prepared for hibernation over the winter. It is anticipated that drilling operations will recommence in early April 2011.
Currently, analysis of the results ascertained from the successful 2010 drilling program is being undertaken.
Results from the DT-1, DT-2 and DT-3 wells will enable the company to undertaken a revaluation of the published Prospective Resources of Davsan Tolgoi.
The 3D seismic survey is being both re-processed and re-mapped, and the previous risking analysis is being re-assessed.
