SOCO Announces Drilling Update in Vietnam

Source: www.gulfoilandgas.com 10/31/2007, Location: Asia

SOCO Vietnam announces that the Voi Nau (VN-1X) well, the first well on Prospect "AA" in Block 16-1, will be plugged and abandoned after reaching a total depth of 3,130 metres. The well was drilled on a four way closure to evaluate the Oligocene section that was productive in Voi Trang. While the well encountered oil shows, the sands were poorly developed and had insufficient porosity to warrant testing.

TGD-1X Well Testing

Following this well, the rig will return to the Te Giac Den 1X ("TGD-1X") well on Prospect "E". As announced on 30 July 2007, the TGD-1X well encountered hydrocarbons in two Oligocene clastic sequences, which were separated by a volcanic layer. Well logs over the upper sequence indicated approximately 30 metres of net pay. After drilling through the volcanics, the well also encountered a deeper high pressure clastic sequence with oil and gas shows. A further 300 metres of sediment is interpreted above the Basement.

Although equipment is now assembled that would enable the section above the volcanics to be tested, detailed analysis of the well, including the benefit of drilling with the high pressure blow out preventer, testing multiple high pressure zones and the extent of the potential formation damage, has supported a decision to re-drill the entire section and conduct a single testing programme.
