On Sept. 11 the Tom Prosser sailed from Singapore on route to Australia and is expected to arrive in Dampier between Sept. 19 and 21. The jackup will drill a well for Vermillion Energy at the Wandoo oil field before commencing Roc-1 drilling operations, early November 2015 (best estimate). The risk of renegotiation and sinking day rate is now an important issue, and we should always be on the lookout. Noble Corp. (NYSE:NE) This article is an update of my preceding article published on Sept. 18, 2015. About the complete Fleet Status as of September 18, 2015. A bit of history: On 6/11/14, Noble also added that it had taken delivery of the newly-built Noble Tom Prosser jack-up from Jurong Shipyard in Singapore. The company said that the Noble Tom Prosser rig will remain in Singapore into the early fourth quarter of 2014 while completing crew familiarization and rig commissioning, prior to going on contract with Apache in Australia.The Noble Tom Prosser will stay with Apache until the third quarter of 2016 at a day rate of $203.500. The contract is expected to begin in the first quarter of 2015. On 3/13, 2015, Noble Corporation and Apache agreed to push back start-up date for newbuild jack-up. Noble Tom Prosser (400' IC - SE Asia): NE and the operator, Apache, have mutually agreed to delay the commencement of the 18-month contract by six months. Originally, the contract was set to start in April 2015, but now that has been pushed back to September 2015. The dayrate of $203k/day remains the same. On 9/14, 2015, We learned that Rig owner Noble Corporation has pushed back the start date of a contract for one of its jack-ups with offshore player Quadrant Energy/Apache. Carnarvon Petroleum Limited (Carnarvon) provided Monday the following update regarding the upcoming drilling of the Roc-1 well in WA-437-P offshore Western Australia.Quadrant Energy is the operator of WA-437-P and contracted the jackup Noble Tom Prosser (400' ILC) to drill the Roc-1 well.On Sept. 11 the Tom Prosser sailed from Singapore on route to Australia and is expected to arrive in Dampier between Sept. 19 and 21.The jackup will drill a well for Vermillion Energy at the Wandoo oil field before commencing Roc-1 drilling operations.At this time, the best estimate for the commencement of the Roc-1 well is early to mid November and the well is estimated to take around 50 to 60 days to complete.

Delays are never a good situation for the offshore drillers, right now, and it is important to see what will happen next? Apparently, this new delay has been mutually agreed by both parties, and nothing drastic has affected the contract and the dayrate is still $203.5/d. The well will be drilled starting November 2015, but we do not know who is going to pay for the two months delay? Recently, Seadrill Ltd. canceled the Semi-sub West Mira, because it could not reach an agreement with Husky oil in Canada, and canceled the rig being built by Hyundai, which was supposed to be delivered in January 2016, instead of September 2015. In fact, Husky oil was more than happy to renegotiate the contract that was canceled "de facto", when SDRL could not present the West Mira on time. The dayrate was negotiated a few years earlier at $590k/d, and even if SDRL can substitute another rig for the work, the dayrate will be much lower now. The risk of renegotiation and sinking dayrate is now an important issue, and we should always be on the lookout. I do not know exactly what was the reason invoked to delay the Roc-1 well, but shareholders should be always concerned, because it may be a sign of a dayrate change? So far, Noble Corp., has been spared from any bad surprise, and I am hopeful as a shareholder, that it will remain that way. Noble spun off Paragon Offshore (NYSE:PGN) last year with three rigs contracted to Petrobras that have been or will be soon canceled due to a large backlog dispute, putting PGN in a very bad financial situation. I am wondering if this situation may not create some friction between PGN and NE? After all, these rigs have been spun off from Noble fleet and this backlog dispute arised when the rigs were part of the Noble fleet, right? More
