Petro Matad updates on Mongolia drilling
Petro Matad has provided an update on its drilling activities on the Davsan Tolgoi Prospect on Block XX in Eastern Mongolia.
Drilling operations on the DT-5 well were completed on 2 June 2011 at a depth of 1,954m below surface. Wireline logging has been completed and the logs have been petrophysically assessed. Numerous thin zones of calculated moveable hydrocarbons were identified, with a cumulative net pay of 3m at the upper contact of the Lower Tsagaantsav, at 1,707m. This zone will be tested in due course. As noted back in May, DT-5 was drilled to test a portion of the paleovalley-filling Uvgan Gol horizon as well as the underlying Lower Tsagaantsav. The well confirmed the presence and configuration of the paleovalley; however, the Uvgan Gol horizon consisted of non-reservoir shales and tight sandstones. The net pay zone at 1,707m is within Lower Tsagaantsav sandstones beneath the basal contact of the Uvgan Gol horizon.
No oil shows were observed during drilling, and petrophysical results indicate low porosity and permeability throughout the entire Tsagaantsav at this locality. The well will be tested during 2011 and, as it is felt likely that stimulation will be required to induce flow at this location, a stimulation contract is being prepared with contractor DQE International.
The drill rig is now being moved to the DT-6 site approximately 2.3km SSE of DT-1. DT-6 will test a thick section of the Uppermost Tsagaantsav (Uvgan Gol horizon) within a well-defined northeast-trending paleovalley, as well as the underlying Lower Tsagaantsav formation.
Petro Matad CEO Douglas McGay said "It is pleasing that our Davsan Tolgoi drilling programme continues to yield positive drilling results, with testable zones in each of the five wells drilled to date."
