Sep 13, 2012 – The Gurame SE-1X well is expected to spud towards the end of September, according to MEO Australia. Success of the appraisal well could lead to early development of the Gurame oil and gas field situated offshore northern Sumatra in the Seruway PSC. The well was identified via 3D seismic as the lowest risk drill-ready candidate with the highest potential for commercial development. Drilling will be undertaken by the Hercules 208 (200′ MLC). Two attractive targets in the well, the Baong and Belumai reservoirs, are expected to be naturally fractured and gas bearing. These attributes should improve the possibility of achieving commercial flow rates. MOE maintains a 100% interest in Seruway.

Sep 12, 2012 – Shell’s much anticipated Chukchi Sea drilling campaign is underway marking the first attempt in 20 years to explore offshore U.S. Arctic petroleum resources. Currently, the Noble Discoverer (mid-water drillship) is being used to drill the mud line cellar and top-hole sections of the first well. This is expected to take two weeks, after which the Discoverer will either continue drilling the Burger prospect or will move to another location to drill the top-hole section. Part of that decision will rest on whether or not the company is able to obtain a permit to drill past the surface sections into the oil bearing portion of the well. Shell has plans to drill three wells in the Chukchi Sea and two wells in the Beaufort Sea if the weather cooperates.

Aug 28, 2012 – Noble Mediterranean Energy along with external consulting firms and the Israeli Department of Energy and Water have selected an alternate plan for sealing and abandoning drilling operations in Leviathan 2 offshore Israel. Drilling will be carried out by the ENSCO 5006 (DW semisub) for an estimated period of 60 days at a cost of $46.6 million. However, due to the complexity of the plan, deviations to these estimates are likely. Noble, the field operator, does not expect any environmental damage to result from the abundance of water produced from Leviathan drilling operations.
Noble and its partners Ratio, Delek and Avner are covered by “control of well” insurance that will takeover expenses for re-drilling and sealing and abandonment of operations up to $200 million per case. So far, the Leviathan 2 partnership has received $53 million for 100% coverage.

When working in the most extreme offshore environments, crews have to be able to rely on the absolute integrity and performance of their vessels. Ulstein Group has joined forces with GC Rieber Shipping to offer the market a new standard in operational security and performance – a ship that refuses to accept failure, thanks to the pioneering ‘operation+’ philosophy.
GC Rieber Shipping, the Norway-based harsh environment shipping specialist, has charged ULSTEIN with developing a high-capacity subsea vessel based on its SX121 design. This NOK 800 million ship, ordered in June 2012, alongside an option for a sister vessel, has been commissioned in response to strong market desire for offshore construction support vessels (CSVs) for deep and harsh environments.
Reliability in the extreme
Alongside state-of-the-art features, equipment and performance figures, the vessel will give GC Rieber Shipping maximum operational availability – a vital characteristic for both the company and those chartering the ship. Downtime will be minimised thanks to the ‘operation+’ feature, an evolution of GC Rieber Shipping’s own ‘fail-to-safe’ design approach.
‘Operation+’ allows the vessel to continue to operate even if it has experienced a significant failure. Bjørn Valberg, GC Rieber Shipping’s Technical Director, explains more:
“Fail-to-safe means that even if a ship encounters a failure it is rendered in a safe condition. Our objective with this ship is to take that philosophy a step further,” Valberg comments.
“In the case of this vessel a single failure – such as a failure of a generator set, a single thruster or even an entire switchboard section (operating two generators and two thrusters) – will not threaten the redundant continuation of operations, giving charterers real peace of mind.”
Valberg illustrates this with a real-life scenario involving subsea flex pipe laying – an operation the new vessel is optimised for – where, if a single failure was encountered, a ‘standard’ ship would be forced to terminate operations as redundancy would be jeopardised.
“And of course,” he states, “if you are in deep waters with a substantial length of product, such as flex pipe, hanging from the ship, abandoning that operation is, well… it’s quite obvious how difficult, time-consuming and expensive that is.
“This new vessel, thanks to ‘operation+’ is protected against that scenario – it could continue with its assignment. That’s a hugely important characteristic of that vessel, helping the charterer meet the demanding expectations of the market.”
Configured for success
ULSTEIN’s design and solutions team has been working to turn this concept into reality and deliver the Holy Grail of minimal operational downtime and maximum efficiency and reliability.
Geir Sivertstøl, principal engineer electrical systems at ULSTEIN, says the vessel, equipped with three main thrusters and three side thrusters (for stationkeeping during pipe laying), is fully optimised for carrying out assignments without interruption.
He notes: ”The switchboard system, propellers and diesel motors can be configured in groups of two, three or four. In case of an AUTR operation (i.e. the occurrence of a single major failure), the vessel will only lose one third of its installed power package and propulsion, and will be able to complete the operation with two thirds of its capacity.”
“This,” he stresses, “in combination with the highest standards for dynamic positioning, DYNPOS-AUTRO, will ensure that charterers can look forward to operational standards that are custom made to tackle the world’s harshest – and potentially most resource rich – environments.”
Equipped, flexible, compelling
GC Rieber Shipping’s version of the SX121 (yard number 300 at Ulstein Verft) has been equipped to meet the most diverse requirements, in the most demanding of conditions.
The 130-metre long, 25-metre wide vessel can accommodate a crew of 130 and cut through deep waters with a top speed of 14.5 knots, while meeting all the latest environmental standards. She is equipped with a powerful 250 ton AHC (active heave compensated) offshore crane, perfect for lifting and lowering heavy equipment to and from subsea environments.
A large cargo deck creates the optimal environment for a variety of operations, ensuring that the vessel is well placed to meet the hugely diverse demands of the offshore construction market. It also offers the ability to carry two ROVs (remotely operated vehicles) – one that will be launched from the starboard side and the other through a moon pool.
In addition, the ship has been designed with SURF (subsea umbilical riser and flowline) capabilities and is prepared for the installation of a below-deck basket/ carousel with a 2500 ton capacity, as well as a 250 ton VLS (vertical lay system) for deployment through the moon pool.
It is, as Valberg stresses, a compellingly comprehensive package: “One of the main reasons for choosing the SX121 design from ULSTEIN was its inherent flexibility, which allows several types of operations and enables us to operate in a wider range of market segments. The fact that we can utilise the 250 ton crane to the maximum of its capability both in offshore and subsea lifts on this vessel was another deciding factor.”
GC Rieber Shipping’s vessel is, according to Tore Ulstein, deputy CEO in Ulstein Group, the ‘perfect project’ for ULSTEIN to show its renowned design and shipbuilding pedigree. Tore Ulstein notes that the business is well accustomed to developing and producing vessels that have the capability to minimise operational downtime, maximising customers’ profits.
He commented: “Our organisation has broad expertise in developing advanced high-capacity offshore vessels together with customers, so this project suits us perfectly.”
The SX121 is scheduled for delivery in the first quarter of 2014, boosting GC Rieber Shipping’s fleet (which was fully booked at the conclusion of 2011) of 18 advanced special purpose vessels, 12 of which are owned by the company.
CEO in GC Rieber Shipping, Irene W. Basili, has imparted that the new addition to the company will “strengthen our position in the high-end subsea segment” and that she is looking forward to receiving “a top-class vessel from ULSTEIN” – a sentiment that potential charterers will no doubt agree with.

Aug 17, 2012 – Premier Oil reported that the Chim Sao North West appraisal well, CS-3X, has reached a total depth of 13,894 feet (4,235 meters). The well has been plugged and abandoned after encountering oil shows in the Middle Dua sands. The appraisal well was drilled to determine whether the Chim Sao North West discovery extended into a separate fault segment to the north. The well targeted the Upper and Middle Dua sands. While 443 feet (135 meters) of sandstone reservoir were penetrated in the Upper Dua interval there was no indication of hydrocarbons. In the Middle Dua interval 541 feet (165 meters) of sands were drilled, but only oil shows were encountered. The CS-N17XP well, which was completed immediately prior to the appraisal well, was drilled to produce from the North West extension to the Chim Sao Field. That well was brought on-stream earlier this month with initial extended production test rates averaging 4,000 barrels of oil per day from four Upper Dua reservoirs.

All of the five exploration wells will be drilled by the Transocean Legend, and lie in the WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries. Karoon Gas holds a 40 percent stake in WA-315-P and WA-398-P, and a 90 percent stake in WA-314-P. ConocoPhillips holds the remaining stakes in the three permits.

Aberdeen-based Helix Well Ops UK (Well Ops), a business unit of international offshore energy company Helix Energy Solutions Group (Helix ESG), is expanding its Europe and Africa well intervention fleet with an investment that will create 60 jobs.
A leading global provider of subsea well intervention, Well Ops will take control of the mono-hull well intervention vessel Skandi Constructor in spring 2013, after agreeing a three-year charter with DOF Subsea.
The move to strengthen Well Ops’ regional fleet, which currently includes the 132-metre (433ft) long Well Enhancer and the 114-metre (374ft) long MSV Seawell, will lead to the creation of approximately 50 jobs offshore and a further 10 onshore over the next nine months. At the moment the firm employs 70 staff in Aberdeen and a further 300 offshore.
Launched in 2009, Skandi Constructor is a 120-metre (393ft) long Ulstein SX121 DP3 mono-hull well intervention vessel that features the new X-bow design. The 8,500-tonne vessel accommodates up to 100 personnel and is capable of working in depths of up to 3,000 metres (9,842ft). It has a deck capacity of 1,470 square metres (15,822 sq ft) and features an 8m x 8m (27ft x 27ft) moon-pool, a 150-tonne crane, a multi-purpose tower with 140-tonne lift capability and two work class ROVs.
Well Ops will build and test, ready for use, a specially designed version of its 7⅜” subsea intervention lubricator (SIL) to enable subsea well interventions to be undertaken from Skandi Constructor. The SIL is a single trip well intervention system that provides well access, while managing containment when the well is ‘live’ and under pressure. The SIL is configured to undertake work through all types of subsea xmas trees. The vessel and SIL will allow Well Ops to provide its regional clients with a solution for deeper water wells and well interventions, which to date has been limited within the mono-hull vessel market.
Steve Nairn, Well Ops’ regional vice president of Europe and Africa, said: “Well Ops is extremely proud to announce the addition of a third vessel to our fleet and it underlines our commitment to providing well intervention services. Skandi Constructor strengthens our offering internationally and expands our well intervention service capability.”
The need for a third vessel in Well Ops’ fleet has been driven by demand from operators in the North Sea and in other oil and gas producing provinces. The firm recently secured contracts from a number of the North Sea’s major operators to provide light well intervention and associated subsea services from its existing vessels between 2013 and 2015.
Internationally, it has also received strong interest from operators, particularly in West Africa. This follows Well Enhancer’s deployment to the region earlier this year, where it completed what was believed to have been the region’s first well intervention project from a mono-hull vessel.
Mr Nairn added: “This is an exciting time for the company and the demand that we are witnessing is illustrative of the level of service and expertise that we can offer clients. As operators continually seek to make their operations more time and cost efficient, it is encouraging that more are turning to mono-hull vessels to conduct well intervention work.
“Our experience of providing an alternative to rig-based intervention systems has been built up over 25 years. MSV Seawell helped to pioneer light well intervention in the North Sea and we have built on this over recent years with Well Enhancer, which was the first mono-hull vessel capable of delivering coiled tubing intervention.”
