Well Summary:

The BU-D05 / BU-D05ST1 development well was drilled from the BU-DPP platform by the Ensco 104 jackup rig. BU-DPP is located in the western half of the Bayu-Undan gas condensate field which is in the Production Sharing Contract (PSC) areas of JPDA 03-12 and JPDA 03-13, North Bonaparte Basin, Timor Sea, offshore Northwest Australia.

The location is approximately 250km south of East Timor and 480km northwest of Darwin. ConocoPhillips (03-12) Pty Ltd is the operator. The Ensco 104 jackup drilling rig (previously the Chiles Discovery) was on contract on the Bayu-Undan Field on 1st May, 2002 following the completion of drilling, completion and flow testing operations on the BU-WP1 platform. The rig was towed to the BU-DPP platform jacket where it was pinned on location on 23rd July, 2003. The BU-D05 well was spudded on 14th September 2003.
