This week the SubseaIQ team added 4 new projects and updated 22 projects. You can see all the updates made over any time period via the Project Update History search. The latest offshore field develoment news and activities are listed below for your convenience.
Jan 31, 2014 – Production from the Guendalina field remains down according the 4Q 2013 Operational Update provided by Mediterranean Oil & Gas (MOG). Low manifold pressure necessitated the shut-in of the GUE 3ss well in August 2013. Eni, the field operator, determined that the reservoir was in good condition and that a blockage in the production string was causing the poor performance. Remedial operations were undertaken in December but progress was hampered by poor weather conditions in the Adriatic. Intervention operations were completed Jan. 11, 2014 and the well returned to a low-production rate. The flow rate will improve as the well cleans up. Eni and MOG maintain 80% and 20% stakes respectively.

Jan 31, 2014 – Salamander Energy sees production from the Bualuang field recommencing in early February after it was stopped in November 2013 when bad weather caused the Rubicon Vantage FPSO to drift off location and damage the production riser. Since then, divers have completed a full inspection and replacement riser and spool materials are being moved to location. While progress is being made, poor weather conditions have slowed repair efforts. A development drilling program being carried out by the Atwood Mako (400′ ILC) has not been interrupted by the event and two production wells have been drilled since the shutdown. Salamander’s production forecast for the field remains unchanged and is expected to average between 13,000 and 16,000 boepd.

Jan 30, 2014 – Through an oversubscribed share placing, Parkmead Group was able to raise $66 million in an effort to bolster some of its activities in the UK North Sea. Parkmead, operator of the Athena field in License P1293, will use a portion of the funds to enhance production from the field. The group plans to carry out a workover of the P4 well. If successful, the operation could increase field production to 9,000 bopd. Locations are also being evaluated for an additional production well that has the potential to add 1,100 bopd to the production stream. Proceeds from the placing will also allow the group to test several prosepcts in its portfolio such as Skerryvore, Possum, Blackadder and Davaar. Well planning is already underway for Skerryvore.

Jan 30, 2014 – Operator Faroe Petroleum announced an oil and gas discovery at its Novus prospect in license PL645 in the Norwegian Sea. Well 6507/10-2S was drilled by the West Navigator (UDW drillship) to a depth of 9,701 feet. A 39-foot net gas column and 41-foot net oil column were encountered in high quality Garn reservoir. Secondary targets in the Ile and Tilje formations proved to be water wet. Results from pressure and fluid sampling indicate the discovery reservoirs hold between 6 and 15 MMboe. Additionally, the results will be integrated into the existing geologic model of the area to de-risk the remaining prospects and leads in the license.

Jan 31, 2014 – Production activities at the West Chirag platform are underway according to the BP-operated Azerbaijan International Operating Company (AIOC). The platform is part of the Azeri-Chirag-Guneshli (ACG) development in the Azerbaijan sector of the Caspian Sea. On January 28, 2014 oil began flowing from the J05 development well. Production will increase throughout the year as additional wells are brought on line. As a whole, the ACG fields have produced over 2.3 billion barrels and, with future development, is expected to be a viable project for many decades. The West Chirag platform was installed in 557 feet of water and has a designed processing capacity of 183 thousand bopd. Startup of West Chirag is the final phase of the Chirag Oil Project and is expected to greatly enhance the deliverability of the ACG development.

Jan 31, 2014 – Shell announced its intention to divest 23% of its interest in the Parque das Conchas development to Qatar Petroleum International for approximately $1 billion. Once the agreement is approved by Brazilian regulators, Shell’s operating interest will be reduced to 50%. Parque das Conchas currently produces at a rate of 50,000 boepd since the Ostra and Argonauta B-West fields were brought on-stream in 2009 as part of Phase 1. Phase 2 was completed in October 2013 when oil production commenced at Argonauta O-North. In July 2013, Shell and its partner ONGC (27%) made the final investment decision regarding Phase 3 and will consist of subsea facilities tying the Argonauta O-South and Massa fields to the Espirito Santo FPSO.

Barclays James West and Zachary Sadow explain:
Our Base case assumes dayrates continue to slide with UDW dayrates dropping to $475k and total average rates dropping 16% from our bull case. We think this is the most likely outcome as we continue to believe the market still needs to work through excess capacity and that conditions will get worse before they get better. In this environment, we anticipate utilization would drop modestly as well. Overall, we expect EPS to be below our 2015 EPS estimates by 38% (ex-HERO) and EBITDA to be 26% below our 2015 EBITDA estimates. Companies with larger portions of fleets derived from older assets would be the most impacted. Under this scenario, all companies in our coverage universe (except Rowan (RDC)) are subject to share price depreciation with an average pullback of 35% (-28% ex-[Vantage Drilling Company (VTG)]). At these levels, we would expect companies with higher leverage levels to be more impacted and see potential for financing events as equity values contract.
Under this scenario, Rowan could gain 2% while Seadrill could plummet 52%, Diamond Offshore could plunge 45%, Transocean could fall 24% and Atwood Oceanics (ATW) could drop 15%.

BP has added two drilling rigs to the deepwater Gulf of Mexico, bringing its fleet to a company record nine rigs as it continues to develop its strong portfolio of assets in the key U.S. offshore basin.
One of the rigs is a new ultra-deepwater drillship known as the West Auriga that is under long-term contract to BP from Seadrill Ltd, a leading international offshore drilling contractor. The vessel, capable of operating in up to 12,000 feet of water, has begun development drilling work at BP’s Thunder Horse field.
The other is a reconstructed drilling rig on BP’s Mad Dog oil and gas production platform. It replaces the original rig on the platform that was badly damaged and left inoperable by Hurricane Ike in 2008. With the new, state-of-the art rig, the platform recently resumed development drilling at the massive Mad Dog field complex.
“The addition of these two rigs reflects the vital importance of the deepwater Gulf of Mexico to the future of BP,” said Richard Morrison, Regional President of BP’s Gulf of Mexico business. “It also clearly demonstrates BP’s commitment to the American economy and to U.S. energy security.”
BP currently anticipates investing on average at least $4 billion in the Gulf of Mexico each year for the next decade. The company plans to concentrate future activity and investment in the Gulf on growth opportunities around its four major operated production hubs – Thunder Horse, Na Kika, Atlantis and Mad Dog – and three non-operated production hubs – Mars, Ursa and Great White – in the deepwater, as well as on significant exploration and appraisal opportunities in the Paleogene and elsewhere.
BP is also advancing a strong pipeline of future development projects in the deepwater Gulf. In April, the company started up the Atlantis North expansion, the first of seven additional wells to be tied back to the existing Atlantis platform. At Na Kika, another field expansion is planned, following the successful startup last year of the Galapagos development, a subsea tieback to the Na Kika production facility. BP is also pursuing plans for a second phase of the Mad Dog field.
Transocean has secured a contract extension for its Discoverer Enterprise drillship in the U.S. Gulf of Mexico.
The nine-month contract extension has been awarded by BP. The extension begins in January next year, with the expiration date set for October 2014. The new dayrate for the drilling unit has been set at $615.000 ($166 million estimated backlog). The rig’s prior dayrate was $515,000.
Discoverer Enterprise is a fifth generation deepwater double hulled dynamically positioned drillship, capable of operating in moderate environments and water depths up to 3,049 m (10,000 ft). From 1998 to 2005 the vessel was Panama-flagged and currently flies the flag of convenience of the Marshall Islands.
Also, the company said it sold the standard jackup, GSF Rig 127, which was previously held for sale. The details of the transaction have not been disclosed.

Corpus Christi, TX – Analysis: From Big Foot to Bluto, Gulf of Mexico set for record oil supply surge
CORPUS CHRISTI, Texas Sun Oct 27, 2013 9:10pm EDT By Kristen Hays and Terry Wade
(Reuters) – The Gulf of Mexico, stung by the worst offshore oil spill in U.S. history in 2010 and then overshadowed by the onshore fracking boom, is on the verge of its biggest supply surge ever, adding to the American oil renaissance.
Over the next three years, the Gulf is poised to deliver a slug of more than 700,000 barrels per day of new crude, reversing a decline in production and potentially rivaling shale hot spots like Texas’s Eagle Ford formation in terms of growth.
The revival began this summer, when Royal Dutch Shell‘s (RDSa.L) 100,000 barrels per day Olympus platform was towed out to sea 130 miles south of New Orleans – the first of seven new ultra-modern systems starting up through 2016. It weighs 120,000 tons, more than 200 Boeing 777 jumbo jets.
The Gulf Of Mexico’s growth will bolster the United States’ emerging role as the world’s top oil and gas producer, a trend led by advances in hydraulic fracturing and horizontal drilling that unlock hydrocarbons from tight rock reservoirs in places like North Dakota’s Bakken and the Permian of West Texas.
Rising domestic production and the start of natural gas exports may transform the economy and realign geopolitics as U.S. reliance on foreign oil declines.
The resurgence in the Gulf is occurring even though the U.S. government imposed stringent safety and environmental rules after BP Plc‘s (BP.L) Macondo spill. Foreign countries from Brazil to Angola have also aggressively courted Big Oil to invest in developing their offshore fields. And the shale boom has diverted billions of dollars in capital onshore.
The deepwater Gulf, considered the most technically challenging offshore oil patch, remains alluring even as other areas struggle. Brazil attracted only a single bid this month for its once-touted Libra field, yet global companies still compete fiercely for the right to drill in the Gulf.
“A barrel of discovered oil in the Gulf of Mexico is difficult to beat for value anywhere else, even with the increased costs of doing business,” said Jez Averty, senior vice president of North American exploration at Norway’s Statoil (STL.OL).
Huge finds over the last decade – in what engineers call “elephant fields” that can produce for 25 years or more – are lifting growth in a basin some companies once abandoned, fearing it was drying up or its resources were beyond reach.
“This is still one of the premier oil and gas regions in the world and that’s why we’ve never left,” said Steve Thurston, vice president of Chevron Corp‘s (CVX.N) North American exploration and production division.
Even after decades of production in the Gulf, government estimates have shown that 48 billion barrels could still be recovered.
The area of the Gulf of Mexico where most of the new infrastructure will start up is in an ancient geological trend in its deepest waters 200 miles or more from shore known as the Lower Tertiary, estimated to hold 15 billion barrels of crude.
Appraisals in the Gulf’s Lower Tertiary have shown fields that could have half a billion barrels or more of oil, like Exxon Mobil Corp’s (XOM.N) Hadrian, estimated to hold up to 700 million barrels, or Anadarko Petroleum Corp‘s (APC.N) Shenandoah, which tests this year showed could hold up to three times more than initial estimates of 300 million barrels.
The potential bounty of massive deposits that can produce for a quarter century or more is what keeps players coming even though a single well that bores tens of thousands of feet through thick salt and rock to strike oil – or a dry hole – can cost $130 million or more.
By contrast, an onshore well costs about $8 million to drill – but may only produce a trickle of oil for a few years.
Chevron’s Jack/St. Malo project, which will tie a platform to the ocean floor 7,000 feet below the surface and tap a reservoir 26,000 feet deep, costs $7.5 billion.
It may become the biggest such platform in the world after shipping out later this year, with the ability to double its initial 170,000 bpd capacity. It will be followed next year by Chevron’s second new platform, Big Foot, to be secured to the sea floor by 16 miles of interlocking metal strands, or tendons.
In addition to projects by Anadarko Petroleum Corp (APC.N) and Williams Cos (WMB.N), private equity firm Blackstone Energy Partners will join the game. In 2015, Blackstone’s partner LLOG Exploration aims to start up Delta House – named for the boisterous fraternity in the film “Animal House” – less than 10 miles from BP’s plugged Macondo well.
Delta House will pump oil from the Marmalard and Bluto fields, namesakes of characters in the movie.
CLEAR AND STABLE RULES
Three years ago, some analysts thought the post-Macondo Gulf would have fewer players as stricter regulations and higher operating chilled activity, particularly for smaller companies.
Producers must now provide more detailed plans for offshore operations, submit to more frequent inspections and prove they have access to a rapid-response system to cap a gushing well. More than 4 million barrels of oil poured into the sea for 87 days after the Macondo well blowout killed 11 men.
High costs have given some companies pause. Even as BP began appraisal drilling at its self-described “giant” Tiber field this August, a month later it canceled contracts to build a second platform at its Mad Dog field. BP says it wants to move forward on Mad Dog 2 “with the right plan.”
Many others are pressing ahead full steam.
“It hasn’t scared us away,” John Hollowell, Shell’s top deepwater executive for Shell Upstream Americas said, noting deepwater is one-third of Shell’s growth platform, alongside natural gas and unconventional areas like onshore shales.
Hess Corp (HES.N) Chief Executive John Hess has told analysts the company, which operates one oil and gas platform in the Gulf with another on the way next year, also aims to increase its exploration in the deep waters.
“It’s a core area for us and now that Macondo is behind the industry, it is an area where we intend to start investing more, assuming we get the returns that we expect,” he said.
Companies say the Gulf is still the best deepwater basin to set up shop – with high profit margins, reasonable per-barrel costs and a predictable legal and regulatory system.
Operators can bring in their own workers rather than employ a certain number from the host country, as they do in Brazil – where just finding enough qualified workers is a hurdle.
Gulf operators also do not have to brace themselves for sudden changes in royalty requirements or possibly be blocked from bidding on drilling rights, as has happened in Angola.
To get in the Gulf of Mexico’s door, they put in the highest bid when the government leases drilling rights.
“All you have to do is show up at the lease sale,” Statoil’s Averty said.

Rowan Companies plc announced today that one of its subsidiaries has entered into a three-year contract with Cobalt International Energy, L.P. for the Rowan Reliance, one of Rowan’s new ultra-deepwater drillships currently under construction at the Hyundai Heavy Industries Co. Ltd. (“HHI”) shipyard in Ulsan, South Korea. The drillship is expected to operate in the U.S. Gulf of Mexico.
The Rowan Reliance is expected to be delivered from HHI at the end of October 2014. The contract is expected to commence late January 2015 following mobilization. The effective day rate for the work will be $602,000, including mobilization revenues, and adds $660 million in revenue backlog.
Matt Ralls, Rowan’s Chief Executive Officer, stated, “We are very pleased to enter into this relationship with Cobalt. They have a very exciting growth story with a strong track record in ultra-deepwater exploration. We will complement their growth potential through our expansion into the ultra-deepwater drilling segment with the most advanced drillships in the industry. We are proud to have this opportunity to be part of the future success of this exciting company.”
The Rowan Reliance is one of four ultra-deepwater drillships being constructed for Rowan by HHI. All four drillships are based on a GustoMSC P10,000 hull design, capable of drilling wells to depths of 40,000 feet in water depths up to 12,000 feet. The DP-3 compliant, dynamically positioned drillship will be equipped with retractable thrusters, two readily deployable seven-ram BOP systems, five mud pumps, dual mud systems and a maximum hookload capacity of 1,250 tons.
With the award of this contract for the Rowan Reliance, three of the Company’s four ultra-deepwater drillships under construction at HHI are now under contract. The fourth remaining uncontracted drillship, the Rowan Relentless, is scheduled to be delivered from the shipyard at the end of March 2015.
Rowan, August 6, 2013
Offshore technology provider AGR Enhanced Drilling, via its subsidiary Ocean Riser Systems, has entered into a NOK120m (USD20m) Letter of Intent (LOI) together with Statoil to deliver the next-generation EC-Drill® Managed Pressure Drilling system.
This latest contract will replace a purchase order made last year, when Statoil joined with Norway-based Enhanced Drilling to further develop its EC-Drill® Managed Pressure Drilling (MPD) solution for floating rigs. The initial phase of the project was worth US$5.1m.
The next-generation EC-Drill® system incorporates state-of-the-art control system capability, enhanced riser integration and multiple other features. Testing of the system is due to commence in the autumn and it will eventually be used on the Norwegian Continental Shelf.
EC-Drill® is a step-change MPD solution, solving a challenge commonly encountered in deep-water wells: drilling within a Narrow Pressure Window. EC-Drill® manipulates bottom-hole pressure by changing the level of drilling mud in the riser, enabling the operator to ‘walk the line’ between pore and fracture pressures. It provides a far greater degree of control than conventional drilling while enhancing safety, plus it is possible to cost-effectively hit deep targets that are simply impractical to reach with more traditional drilling techniques.
David Hine, Executive Vice President at Enhanced Drilling, said from the company’s head office in Straume: “This further commitment by Statoil is another significant endorsement of EC-Drill® as a game-changing technology and the benefits that it brings. This next-generation system is a further step in taking Enhanced Drilling towards the forefront of the MPD market.”
The drillship is expected to be delivered at the end of the second quarter 2014 and operate in the U.S. Gulf of Mexico starting in the late third quarter 2014. The Rowan Resolute is one of four ultra-deepwater drillships being constructed for Rowan by Hyundai Heavy Industries Co. Ltd. (“HHI”) shipyard in Ulsan, South Korea.
With the award of this contract for the Rowan Resolute, two of the Company’s four ultra-deepwater drillships under construction at HHI are now under contract. The remaining two uncontracted drillships are scheduled to be delivered from the shipyard at the end of October 2014 and March 2015.
Rowan, in its fleet status report, said that the day rate for the contract is in the high $600.000s.
Rig contract in Indonesia
Also, the company has informed it has secured a 170 day contract with Pertamina Hulu Energi for Gorilla II rig in Indonesia at a day rate in the high $160s (above previous day rate in the mid $130s) expected to commence operation in September 2013.
Further in the report for June 2013, Rowan said it has sold the Rowan Paris rig for $40 million in June 2013.
