AGR Commences Drilling of High-Impact Exploration Well in Australia’s North West Shelf
Pioneering Spirit’s Direct Lift From Quayside at Lerwick Harbour
The world’s largest offshore construction vessel, Allseas’ Pioneering Spirit, successfully completed delivery of the 8,500 tonne Ninian Northern platform jacket for decommissioning at Dales Voe, Shetland.
AGR’s Well Management Division has spudded the Sasanof-1 exploration well in Australia’s Carnarvon Basin, on behalf of Western Gas.
The semi-submersible Valaris MS-1 rig arrived at the deep water well location last week and spud the well in the Carnarvon Basin, approximately 207 km off North West of Onslow.
A recent report on the contribution of high impact wells released by IHS Markit (part of S&P Global) earlier this year, cited the Sasanof Prospect as being one of only two high impact wells in the Asia Pacific region of the 20 global high impact wells planned due to be drilled in 2022.
Based on the independent estimates, the Sasanof Prospect contains a 2U Prospective Resource of 7.2 Tcf gas and 176 Million bbls condensate (P50), with a high case 3U Prospective Resource estimate of 17.8 Tcf gas and 449 Million bbls condensate (P10).
Lerwick Port Authority Chief Executive, Captain Calum Grains, “The second successful visit by Pioneering Spirit highlights another example of the deep-water harbour’s capacity and facilities to handle large vessels and major projects for energy industries and points the way to future operations.”
On arrival from the North Sea, Pioneering Spirit went directly to the Port Authority’s Dales Voe Base – the first time she has operated at quayside in a UK port – to lift steel structures onto a barge for removal following their use on her first visit to deliver the Ninian Northern topside in 2020.
The huge 382-metres-long and 124-metres wide vessel then manoeuvred mid-voe to transfer the 83-metre-high jacket via the Allseas barge, Iron Lady, to the Base where it was loaded-in to a heavy-duty pad in a complex operation.
The jacket is being decommissioned by international partnership, Veolia/Peterson, which also processed the topside. Before sailing from Lerwick, Pioneering Spirit mobilised in the voe for her next project. Video of the whole operation:
