Plans unveiled to drill world’s deepest well

HOUSTON -- Discussion of a plan to drill  in the seafloor more than 12,000 feet beneath the surface of the Pacific Ocean  impressed even the technical professionals at the Offshore Technology Conference, who already know a lot about doing complicated work under water.

The project,  scheduled for 2017 in the Pacific Ocean, would involve drilling a scientific well  to retrieve a core of the Earth’s mantle. It would bring the sample to the surface using a riser similar to the pipe that connects underwater wellheads to surface rigs.

If successful, it would drill in water as deep as 12,000 or 14,000 feet, well beyond the deepest drilling now, around 10,000 feet.
Nicolas Pilisi, an engineer for Blade Energy Partners, said the  greater water depths are accessible with changes in materials used and with additional power to move mud and other materials into and out of the hole.

While  steel risers used now are too heavy and pose a risk of buckling at greater depths, innovative designs using thinner risers, or ones made from titanium or aluminum, would offer strength and also cut down weight, Pilisi said.

Those advancements — which Pilisi said aren’t far from reality — could advance offshore capability, especially if the project settled for a more shallow site off the coast of Hawaii.

“Drilling and coring a scientific hole in the upper mantle is definitely possible,” Pilisi said. “A hole could be drilled today with the existing technology.”

Anadarko reports strong results from Utica program

HOUSTON -- Anadarko Petroleum Corporation provided an update on its drilling program in the Utica Shale play in eastern Ohio after filing the required production history with Ohio Department of Natural Resources. To date, the company has drilled and is producing from three wells in the Utica Shale, the most recent of which has delivered more than 9,500 barrels of light-gravity crude oil during its first 20 days on line.

"Though it is very early in our exploration program, the strong initial results are encouraging," said Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration. "We expect to begin flowing back our fourth Utica exploration well in the next few days and are currently drilling our fifth exploration well in the play. We plan to continue an active drilling program throughout the year, as we evaluate the liquids-rich potential of our 390,000-acre (gross) position in the Utica Shale."

Anadarko's Brookfield A-3H well in Noble County has produced approximately 9,500 barrels of oil and approximately 12 million cubic feet (MMcf) of high-BTU (British thermal units) natural gas during its first 20 days on line. The Spencer A-1H and Spencer A-5H wells, located in Guernsey County, have cumulatively produced a combined 20,000 barrels of light-gravity crude oil and 37 MMcf of liquids-rich natural gas in just under two months on line. All three horizontal wells were drilled to a vertical depth of approximately 6,500 feet and a lateral length of about 5,000 feet with 16- to 19-stage completions.

Anadarko operates the Brookfield and Spencer wells with a 100-percent working interest (82.5-percent net revenue interest) subject to a participation agreement with Artex Energy Group LLC.

Total weighing Elgin options

PARIS -- Total is still accessing its options with regards to plugging a large gas leak at a North Sea facility which the French major says is diminishing.

One of two rigs chartered with a view to drilling relief wells also continues towards the scene of the leak from the Elgin processing, utilities and quarters (PUQ) platform but will stand off at the perimeter of an exclusion zone, a spokesperson told Upstream on Monday.

Last week Total will send a team of well control experts b y helicopter to the leaking facility and, although they returned safely, the company has yet to decide on a plan to stop the leak.

Total is considering a ‘top kill’ procedure to plug the leak using drilling mud. Simultaneously it intends to begin drilling two relief wells which would be halted should the top kill job be successful.

Transocean’s Sedco 714 rig is en route to the scene, the spokesperson said. A broking source suggested last week that it would arrive on the scene on Sunday or Monday.

The Rowan Gorilla V has also been hired by the French company with a view to drilling relief wells.

Total shut in all production at its Elgin and Franklin fields following the discovery of the leak over two weeks ago. The oil major evacuated all 238 workers from the Elgin facility and the adjacent Rowan Viking.

Anglo-Dutch supermajor Shell also pulled all workers from its nearby Shearwater platform.

ConocoPhillips begins Browse basin campaign

Karoon Gas Australia Ltd's 2012 Browse Basin exploration drilling campaign has now commenced.
The Boreas-1 exploration well spudded at 02:30 (WST) on April 5, 2012. The proposed operation is to drill a 36" hole to planned casing point, then run and cement the 30" conductor prior to drilling ahead in a 17½" hole.

Boreas-1 is located approximately 2.5 miles (4 kilometers) south of Poseidon-1 in WA-315-P on a large tilted fault block which is part of the of the north-east trending structural high of the greater Poseidon structure. The objective of the well is to test the extent, presence and quality of reservoirs within the Boreas-1 fault block.

Boreas-1 Location:
• Latitude: 13 degrees 39' 24.87170" S
• Longitude: 122 degrees 17' 52.78733" E

UPCOMING WELL PROGRAM
The exploration program, operated by ConocoPhillips, plans to utilize the Transocean Legend (mid-water semisub) rig for the entire campaign and is expected to continue through 2013.

A minimum of five wells will be drilled during the exploration program. The principal objective of the exploration program is to better define the size and quality of the hydrocarbon accumulations within the exploration permits which contain the greater Poseidon trend.

The second well, Zephyros-1, is located in permit WA-398-P on a large tilted fault block approximately 5 miles (8 kilometers) south west of Kronos-1 discovery location. The third well, Proteus-1, is located in WA-398-P on a large tilted fault block approximately 9 miles (14 kilometers) south east of the Poseidon-1 discovery location.

Additional well locations for the remainder of the program will be announced as they obtain joint venture approval.

ConocoPhillips is the operator of the jointly held WA-314-P, WA-315-P and WA-398-P Browse Basin permits containing the previously announced Poseidon and Kronos gas discoveries. Karoon Gas Australia Ltd holds a 40-percent interest of permit WA-315-P and WA-398-P, and a 90-percent interest of permit WA-314-P.

Worldwide upstream M&A unconventional resource spending reached record high $75 billion

NORWALK, Conn. – Fueled by national oil companies and international buyers making acquisitions in North American shale gas, shale oil and tight oil basins, global transactions involving unconventional oil and gas resources reached a record high $75 billion in 2011, according to the IHS Herold 2012 Global Upstream M&A Review, which was just released by information and analytics provider IHS (NYSE: IHS). This figure represents 48 percent of total 2011 worldwide upstream merger and acquisition (M&A) spending

“Cross-border buyers, led by Asian-based investors, continued to stream into North American unconventional resource plays through asset partnerships and select corporate deals, with a bullish view on potential LNG exports to the Asia-Pacific region in the coming decades,” said Christopher Sheehan, director of energy M&A research at IHS. “In 2011, high crude oil and international gas prices were juxtaposed against persistently depressed North American natural gas prices, leading to a 15-year high in deal counts outside North America.”
Total global upstream M&A transaction value, including corporate mergers, fell 30 percent from an all-time high in 2010, which was driven by massive asset divestiture programs. Corporate deal value in 2011 rose 19 percent to more than $58 billion, including BHP Billiton’s $15 billion takeover of unconventional resource-focused Petrohawk Energy, the first upstream corporate merger greater than $10 billion since the ExxonMobil-XTO deal in late 2009.
Sheehan noted the deal flow also increased in all regions outside the U.S. and Canada as international investors pursued the prolific oil discoveries that have occurred in recent years in regions such as deepwater Brazil and Africa. In Australia, the coal seam gas-to-LNG market consolidated further, and evolving markets such as Iraq’s Kurdistan region welcomed new entrants through M&A.
Said Sheehan: “These areas are enticing international investors who continue to face access barriers in established hydrocarbon basins such as Venezuela, Russia and in the Middle East. World-class oil assets continue to be highly sought after by both cash-rich national oil companies and international integrated companies that continue to struggle to materially grow reserves through the drill bit.”
In the international gas markets, growing Asian LNG demand will increasingly fuel merger and acquisition activity from Australia to East Africa. In these regions, Sheehan believes small-cap international E&Ps that own huge resources, but lack sufficient development capital, will increasingly be takeover targets, particularly as the European debt crisis has impacted their access to and the costs of capital.
U.S. transaction value in 2011 reached a 10-year high despite a lower deal count than the prior year, as large joint-venture asset acquisitions by overseas buyers fueled mergers and acquisition activity. The U.S. accounted for approximately 50 percent of global upstream M&A spending, well above its historical average. Producing oil assets commanded a large deal price premium to gas properties, with a growing focus on liquids potential in emerging basins.
“Established shale gas and emerging shale oil and tight oil plays in the U.S. are attractive to foreign buyers since these plays offer massive discovered resources with low exploration risk in a country with relatively high political and fiscal stability, versus other global regions such as the Middle East, Africa and Latin America. The longer-term potential of LNG exports to the Asia Pacific from Canada and the U.S. is a strategic driver of many of the cross-border shale gas acquisitions in North America,” Sheehan added.
Meanwhile, decade low deal pricing for conventional gas assets, and the upside from liquids-prone plays, attracted increased M&A spending by private equity buyers seeking to benefit from a longer-term North American natural gas price revival.
Continued uncertainty in commodity price direction, wide-ranging geographic oil and gas price spreads, fragile global economic conditions, and limited or higher cost access to capital for many upstream companies are challenging strategic decision making in the industry and causing a consensus gap between potential buyers and sellers.
Added Sheehan: “We believe that, in the present volatile environment, global upstream M&A consolidation will accelerate in 2012 and beyond as the well-financed ‘haves’ prey on the capital-constrained ‘have-nots.’ Many of the latter are key holders of massive undeveloped gas and liquids resources that can provide material growth opportunities or establish a strategic foothold in emerging basins. Consolidation, including a rise in corporate takeovers, will be led by national oil companies and sovereign-wealth funds, major integrated companies, global industrial conglomerates, and private-equity investors, who all seek opportunistic purchases of capital-intensive oil and gas assets and financially strained companies that own prolific resource potential.”
IHS provides comprehensive analyses of 2011 transactions and forward-looking insights into 2012 and beyond in the just-released IHS Herold 2012 Global Upstream M&A Review. This year, the study identifies thirty key regional plays across the globe that need to be on the radar of oil and gas M&A market participants, including buyers, sellers, advisors, and capital providers.
The regional profiles in each of the study sections are drawn from the IHS Herold Company Research module Regional Play Assessments (RPAs), which use IHS proprietary geological data to independently value the resource potential and investment opportunities in established and emerging oil and gas plays around the world. This research features detailed analysis of company well results, acreage positions, drilling activity, financial strength, play economics and company and asset valuations.

Exxon, BP, Conoco agree to initial Pt. Thomson gas production by early 2016

HOUSTON -- Exxon Mobil, ConocoPhillips and BP have agreed to start producing natural gas at their Pt. Thomson development in Alaska by May 2016 at the latest, according to a settlement agreement between the companies and the state of Alaska.
The oil companies will be allowed to continue developing Pt. Thomson in exchange for the commitment to begin producing natural gas and condensate by end of the winter season of 2015-2016. The initial production system, which could be later ramped up, is being designed to produce about 200 MMcfd of gas and 10,000 bpd of condensate. Also, a pipeline is being designed to move about 70,000 bpd of liquid hydrocarbons from Point Thomson that will help move the fossil fuels to the Trans-Alaska pipeline. The companies also agreed to "undertake work for commercialization of North Slope gas," the document said. The Alaska government has said it would like to see a liquefied natural gas development to ship local natural gas to Asia. If a deal to sell the natural gas hasn't been struck by June 2016, the companies agreed to expand the amount of natural gas condensate shipped to the Trans-Alaska pipeline by 20,000 to 30,000 bpd. Point Thomson gas could also be delivered to oil operations in Prudhoe Bay for injection into the large oilfield there, the document said. The agreement said that a "major gas sale off the North Slope of Alaska is a primary goal of the parties."
The settlement puts to rest a long-standing dispute between the oil companies and the Alaska government. In 2006, the state revoked the Point Thomson license it had assigned Exxon and its partners alleging they hadn't moved quickly enough to develop the resource.
