Eni Australia BV (Eni) operates the Blacktip facilities, approximately 300km west south west of Darwin, located in Lease Area WA-33-L, within Commonwealth waters in the Joseph Bonaparte Gulf (JBG). The facilities consists of a normally unpopulated wellhead platform (WHP) in approximately 51m water depth, platform wells, flowlines, and a subsea gas export pipeline (GEP) (Licence WA-15-PL, NT/PL2) bringing whole well stream fluid (as in, gas, condensate and produced water) to the Yelcherr Gas Plant (YGP) near Wadeye in the Northern Territory (NT). Stabilised condensate is stored on site at the YGP before being exported via a subsea condensate export pipeline (CEP) (NT/PL3) to a single point mooring (SPM), located approximately 7km offshore in Commonwealth waters, for loading to tanker vessels and subsequent transport to market.
The Blacktip Drilling Environment Plan (EP) is a standalone drilling EP covering the development drilling and completion scope for a new Blacktip development well at the WHP. The nearest shoreline is approximately 100km to the east and 100km to the south. The schedule for these drilling activities will be subject to jack-up mobile offshore drilling unit (MODU) availability; however, is anticipated to take place between 2024 and 2027. Once drilled, the new well will be shut in, its hook-up, commissioning and production will be covered under the Blacktip Operations EP (000036_DV_PR.HSE.0677.0000).
The scope of the Blacktip Drilling EP includes:
• A geophysical survey at the WHP
• The mobilisation, positioning, and demobilisation of a jack up MODU at the WHP
• Drilling and completions of a new development well in the Blacktip field through an existing slot on the Blacktip WHP
• Intervention on current production wells at the WHP (rig-based)
• Contingent workover operations on current production wells at the WHP
Ongoing operations of Blacktip facilities, including the production from Blacktip wells included in Blacktip Operations EP (000036_DV_PR.HSE.0677.000)
