Tungsten Explorer

12,000 ft.
Drillship
Vantage Drilling confirmed that the Tungsten Explorer (UDW drillship) has received a letter of award for work which is expected to start upon delivery from the shipyard. Industry sources have reported that the contract is with PTTEP Myanmar for one well in Block 11. A total contract value of $68.2 million was reported for the PTTEP well. However, channel checks have suggested that the clean rate for the contract is in the low-$580s. Vantage says they are also working on securing another contract to fill in the gap between the PTTEP well and the start of the Total contract at Moho Nord in mid-2014.

Noble Cat J Jackup TBN
|
500 ft.
Jackup
Statoil and its partners in the Mariner field have selected Noble Drilling to supply and operate the Category J jackup which will be used for the project. The Cat J is based on the MSCGusto CJ-70-150 design and will be rated to work in water depths up to 492 feet with a rated drilling depth capacity of 33,000 feet. The rig will be capable of working in harsh environments and have the ability to deploy either a surface or subsea BOP. Construction cost is expected to be approximately $690 million. While a yard has not yet been selected, Noble is reported to be in talks with Jurong and Daewoo. The deal comes with a four-year contract valued at $655 million, including mobilization fees. Statoil received development plan approval from UK's DECC in February. Mariner is located east of the Shetland Isles. Statoil expects to start production from Mariner in 2017. The field is expected to produce for at least 30 years. The average production is estimated at around 55,000 barrels of oil per day over the plateau period from 2017 to 2020.
