Norway to Power Offshore Platforms from Land?

image

The operators and licence holders for the Johan Sverdrup, Dagny, Draupne and Luno fields in the North Sea will study setting up a hub for the supply of electrical power from land. The study will form the basis for a decision on electrification.

The study, which has been initiated by the Ministry of Petroleum and Energy, is headed by Statoil and involves the operators Lundin and Det norske oljeselskap, as well as the other licence holders. The work will comprise technical studies, such as concept planning, as well as commercial solutions for the electrification of the fields on the Utsira High. The intention is to create a framework for potentially setting up a company or partnership to own and operate the facilities that will feed the receiving platforms with power.

It is primarily the gigantic Johan Sverdrup discovery – together with Luno, Draupne and Dagny, including Eirin – that makes such a shared power solution possible. Preparations will be made for the possible subsequent tie-in of other installations on the Norwegian continental shelf.

The study will take in an offshore distribution platform located near Johan Sverdrup, with DC cables from land to the distribution platform and AC cables on to the receiving platforms. An analysis of the power situation at the potential land-based connection points will also form part of the study.

There will be the additional requirement for converters and transformers on the distribution platform and on land. AC cables will also be necessary and the existing switching station will need to be extended for connection to the grid network.

The progress plan for study will, to a large extent, be governed by the plans of those who will be in receipt of the power.

A concept will be selected, and the investment decision made,at the earliest in the fourth quarter of this year.

The decision to electrify will be taken by the licence holders/owners, on the basis of profitability, the official specifications and the conditions stipulated . Utsira Height can be well suited for electrification due to its considerable power needs, as well as the favourable distances and water depths involved.

MacGregor Systems for New OSVs in Asia and Europe

image

MacGregor bulk handling systems are to be installed on four offshore support vessels (OSV) of various types under construction in Asia and Europe.

In the last quarter of 2011 Cargotec secured contracts for MacGregor bulk handling systems for installation onboard four offshore support vessels (OSV) newbuildings belonging to two different owners; one in the UAE (two vessels) and the other in Spain (two vessels).

At the end of November, Grandweld Shipyards in the United Arab Emirates ordered MacGregor bulk handling systems for two anchor-handling tug/supply (AHTS) vessels, hull Nos 389 and 390. They will handle cement, barite and bentonite for their owner Halul Offshore Services Company, in Doha, Qatar. Equipment for both vessels is scheduled for delivery at the end of June 2012.

In December Cargotec received an order for MacGregor bulk handling systems to be installed on two PSVs (hull Nos 446 and 447) under construction at Astilleros Balenciaga S.A. in Spain, for North Star Shipping in Scotland, UK. The vessels will operate in the North Sea and will handle cement, barite and bentonite. The equipment is scheduled for delivery in June and November, 2012.

“For the owners, it was important that the vessels were fitted with simple and well proven bulk handling technology, with a solid track record,” says Pankaj Thakker, Cargotec Sales Manager, Marine Selfunloaders. “Each installation will feature dust-free operation and low power consumption, making these some of the most environmentally-friendly systems available today.”

Bulk handling systems are standard equipment for offshore support vessels, enabling them to perform their supply role. The main task of such a system is to receive cargo, store and discharge it. MacGregor can offer operators two main system types: one uses a more conventional method where the storage and discharge of cargo is carried out using pressured tanks; and the other uses the hopper and blow pump concept.

Odfjell Drilling has been awarded a significant pre-contract award with BP for the provision of a new build, semi-submersible drilling unit for use in the UK’s West of Shetland region. The contract value is approximately $1.2 billion, excluding options, and represents the largest contract in Odfjell Drilling’s 40 year history.

The new unit will be involved in drilling in the Schiehallion and Loyal fields and will form a key part of the Quad 204 development. The full contract, which is subject to approval by the Quad 204 Partnership, will have a fixed duration of 7 years and is due to start in Q4 2014.

In July 2011 BP announced a decision to progress a major re-development of the Schiehallion and Loyal oil fields to the west of the Shetland Islands.

Schiehallion and Loyal have produced nearly 400 million barrels of oil since production started in 1998 and an estimated 450 million barrels of resource is still available. The investment of circa £3 billion in the re-development of the fields will take production out to 2035 and possibly beyond.

President & CEO of Odfjell Drilling, Simen Lieungh states:

“This contract award from BP is of great importance and represents a solid contribution to the company’s further growth and is a recognition of Odfjell Drilling’s status as a reputable international drilling contractor. We have a track record of delivering new build units on time and on budget and this new build for BP will be the fifth new deep water unit for the company. We highly value our relationship with BP and look forward to developing this relationship further in the future.”

Jim Cowie, BP Vice President for Wells, said: “The Quad 204 partnership is making this major investment in its drilling capability in response to high future demand West of Shetland and a desire to invest in the latest equipment that can help deliver its business plans. This is an exciting development and one which builds on BP’s recent announcements concerning its investments in the North Sea. Odfjell Drilling is a safe, efficient and innovative drilling contractor that is performing well for BP in the North Sea and with Deepsea Stavanger offshore Angola.”

Fifth deepwater unit delivery

The new state of the art Sixth generation rig will be built in South Korea by Daewoo Shipbuilding & Marine Engineering (DSME).

“The new rig for BP is of the enhanced GVA7500 harsh environment design and will be a sister rig of the Deepsea Atlantic and Deepsea Stavanger previously delivered to us by DSME. We are pleased to continue our collaboration with DSME, says Mr. Lieungh.”

Construction engineering has commenced and keel laying is scheduled for March 2013.

image

Aquaterra has successfully installed a ‘world first’ 10,000psi rated, 20” I.D. full bore drilling riser for Apache North Sea.

The unique High Pressure Riser System was designed specifically for Apache North Sea to drill three subsea wells on the Bacchus field from the Rowan Gorilla VII. The installation marks the first Riser System of this kind to be run worldwide.

Aquaterra Energy built on the success of their 5,000psi Riser System, using Merlin Connectors developed by Oil States Industries (UK) Ltd to produce a higher capacity, 10,000psi system in conjunction with Oil States. The 10k System is a ‘world first’ as never before have Merlin connectors been used at this size or pressure, for this application. To cope with the increased pressure and anticipated loads, the joints were fully forged with a wall thickness of 2 ½” and the overall dimensions of the Merlin Connector were increased greatly. The Merlin Connector significantly increases running speed and improves the efficiency of operations when compared to standard flanged alternatives. With a unique service agreement in place with Oil States Industries, Aquaterra Energy is the only service company providing this exclusive rental system to the market.

High Pressure Drilling Riser specialists, Aquaterra Energy, offered a full scope of supply to Apache North Sea ranging from Riser Analysis to offshore installation. Aquaterra’s dedicated in-house team of Drilling Riser Engineers provided design engineering, project management, operational expertise and managed the delivery of the riser system as well as offshore installation

Aquaterra Senior Project Engineer, Stuart Dockree managed the project and commented, “The overall project was extremely interesting with many engineering and operational planning challenges throughout, which required continued focus from the project team. Speaking on behalf of that team, we have all been delighted to be involved with this significant ‘world first, full bore 10k Merlin riser system’ project which has further strengthened our riser team and product lines as clear market leaders for High Pressure Riser Systems.”

Aquaterra Project Engineer, James Head, who supervised the Riser installation on the Rowan Gorilla VII said, “A positive working relationship and excellent communications between Aquaterra Energy and Apache North Sea throughout the offshore operation ensured that the Riser System was installed to plan. The operation went smoothly as all parties pulled together to ensure a successful outcome.”

EnCore Reaches TD in Tudor Rose
Dec 28, 2011 – EnCore Oil has encountered an oil column in the Tudor Rose well within the targeted Beauly formation and oil water contact at 3,236 feet (986 meters) total vertical depth. The operator gathered wireline samplings and conducted pressure testing of the hydrocarbon-bearing zone. Initial wellsite analysis of the samples suggest a viscosity of 600 to 800 Centipoise, which is likely too viscous to be commercially exploitable. EnCore says further onshore analysis is required before the provisional evaluation can be confirmed. The well will be plugged and abandoned. The Tudor Rose well is located on Block 14/30a in the UK sector of the North Sea. EnCore operates the block with a 40 percent interest; while Nautical Petroleum holds 20 percent; Endeavour holds 20 percent; and EnQuest holds 20 percent.

Antrim Sidetracks Erne Discovery
Dec 27, 2011 – Antrim Energy announced that the Erne discovery well sidetrack, 21/29d-11Z, encountered about 24 feet (7 meters) of net oil pay and 14 feet (4 meters) of net gas pay in a high-quality sandstone reservoir. Initial interpretation is that the well has penetrated a separate accumulation from that in the 21/29d-11 discovery well, but further work is necessary to confirm this, stated the operator. The 21/29d-11Z well will now be suspended for potential future re-entry and use in the development of the Erne discovery. The 21/29d-11Z well was designed to appraise the Erne oil discovery in the Eocene Tay formation, and was drilled up-dip of the discovery location to a total depth of 5,124 feet (1,562 meters). Erne is located in Block 21/29d in the UK sector of the North Sea. Antrim Energy operates Block 21/29d.

BG Discovers Oil in PL 373 S
Dec 27, 2011 – BG Norge has made an oil discovery in the North Sea in Production License 373 S. The wells, 34/3-3 S and 34/3-3 A, proved oil in early Jurassic sandstone. The objective of the well 34/3-3 S was to prove hydrocarbons in the Cook formation of the early Jurassic age in the Jordbaer Vest prospect. Oil was proven in the upper part of the Cook formation with very good reservoir quality. The objective of the 34/3-3 A sidetrack was to delineate the 34/3-3 S discovery by confirming the extent of the reservoir rocks, and also proving oil in the lower part of the Cook formation. The well proved oil both in the upper and lower Cook formation with very good reservoir quality. Extensive data acquisition programs have been carried out in both wells. Preliminary estimates place the size of the discovery between 1.5 and 4 million standard cubic meters of oil equivalents. The licensees will consider developing the discovery with the Knarr development, which was approved in June 2011.
Project Details: Knarr (Jordbaer)
Statoil Considers Skrugard Development in the Barents Sea
Dec 27, 2011 – Statoil and partners are considering developing the Skrugard discovery in the Barents Sea by a floating production unit with additional capacity to process and transport from other prospects in the vicinity. Statoil says a feasibility study has identified a technical and commercial solution for Skugard, resulting in the rapid development of the discovery. The production unit will have separate oil and storage and offloading capability with a production capacity of 95,000 bopd. The field development calls for 14 oil producers and pressure support will be provided via injection wells for water and gas. Skugard is estimated to hold around 250 MMbbl of recoverable oil equivalents, with a considerable upside potential. Statoil plans to drill an exploration well on Havis, a prospect located roughly five kilometers from the Skrugard discovery, but within the same license. After drilling the Havis well, the rig will drill an appraisal well on Skrugard. Skrugard is located in Production License 532, which Statoil operates, holding a 50 percent interest. Partners in the license include Eni Norge (30 percent) and Petoro (20 percent).

Otto will submit the required assignment documents to the Philippine Department of Energy for their approval of the transfer of participating interest to BHP Billiton. Upon completion of the farm-in, Otto’s working interest in SC 55 will reduce to 33.18 percent.
Cairn to Enter Second Phase of Exploration
Dec 27, 2011 – Cairn Lanka Limited has successfully completed the first phase of the exploration campaign in Sri Lanka Block SL-2007-01-001. The exploration program involved the acquisition, processing and interpretation of 433,175 acres (1,753 square kilometers) of 3D seismic data and a three-well deepwater drilling program. The seismic program exceeded the first phase commitment by 20 percent, and the drilling program exceeded the drilling depth commitment by 50 percent. Cairn said this program resulted in two successive gas and condensate discoveries; the CLPL-Dorado-91H/1z well and, the CLPL-Barracuda-1G/1 well. The third well, CLPL-Dorado North 1-82K/1 was plugged and abandoned as a dry hole. This drilling program has found an established working petroleum system in the frontier Mannar Basin. Cairn Lanka intends to enter the second phase of exploration.
