Well Summary


The BU-D07 water disposal 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 was on contract within the Bayu-Undan Field on 1st May, 2002. Following the completion of drilling, completions 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. BU-D07 was spudded in on 21st September 2005, as part of batch drilling procedures with other DPP wells. The well was drilled to the North-West and reached a total depth of 2191.8 mMDRT in 8 ˝" x 9 ⅞” hole size on 21st March 2005. BU-D07 was cased and completed in the Johnson Formation as a water disposal well. The total number of days at the BU-D07 location was 15 days. As BU-D07 was the last well drilled in Phase I of the Bayu-Undan Development Project, the ENSCO 104 jackup rig was released on 7th April 2005.

LOGGING

Mud logging

Sperry-sun Drilling Services provided the mud logging services with formation evaluation and pressure monitoring services from 126.7 mMDRT to total depth. Drilling rate, calcimetries, lithologies, total gas and chromatographic analysis of the ditch gas are plotted on the mudlog. Pressure indicators were measured and are plotted on the pressure log. Mudlog ASCII data and plots are included on the BU-D07 Well Completion Report, Volume 1: Basic Data CD within the MUDLOG directory

LWD Logging
Sperry-sun Drilling Services ran the open hole LWD logs as seen on the table provided below.
Wireline Logging
No wireline logging was acquired.
