BHP Billiton: Funds Approved for Mad Dog Phase 2 (USA)


BHP Billiton today announced approval for US$708 million (BHP Billiton share) in precommitment funding for the Mad Dog Phase 2 project in the deepwater Gulf of Mexico. The funding will facilitate detailed engineering and the procurement of long lead time items related to the hull, topsides and subsea equipment.

The Mad Dog Phase 2 project is based on successful appraisal drilling which confirmed significant hydrocarbons in the southern portion of the Mad Dog field. The proposed project includes the development of a second spar facility with all subsea production and injection wells. The new facility is estimated to have a design capacity of approximately 130,000 barrels of oil per day that will be exported via the Mardi Gras Pipelines under existing agreements. A final investment decision is anticipated in calendar year 2013 with first production scheduled for calendar year 2018.

BHP Billiton Petroleum Chief Executive Officer, J. Michael Yeager, said: “Mad Dog Phase 2 will join our extensive Gulf of Mexico portfolio that includes Mad Dog and Atlantis as well as the Shenzi and Neptune platforms that we operate. The extension of this field will underpin continued valuable liquids production from the Gulf of Mexico and further enhance our growth profile.”

Mad Dog is a partnership between BP (operator, 60.5 percent share), BHP Billiton (23.9 percent) and Chevron (15.6 percent).


Australia: Tap Taps into Tallaganda

Australia: Tap Taps into Tallaganda| Offshore Energy Today

Tap Oil Limited (Tap) advises that at 0900 hours (AWST) today the Atwood Eagle semi-submersible drilling rig commenced drilling the Tallaganda-1 exploration well in the WA-351-P permit.

The Tallaganda-1 prospect straddles both the WA-351-P and WA-335-P permits in the Carnarvon Basin, offshore Western Australia. The well will target 0.8 to 1.3 Tcf (mean to P10) of gas within WA-351-P (Tap estimate).

The prospect will test the gas potential of sandstones in the prolific Triassic age, Mungaroo Formation, in a well defined horst block as imaged by high quality modern 3D seismic data. This is the primary play type of the North West Shelf.

The well will be drilled as a vertical well in a water depth of 1,141 m and is expected to take 37 days (trouble free) to drill with a projected total depth of 4,250 m. Weekly updates will be provided on Wednesdays during drilling operations.

Tap’s cost for the well will be carried up to a cap of $10 million following Tap’s farmout of 25% of its participating interest in the permit to BHP Billiton Petroleum (North West Shelf) Pty Ltd in 2011.

Tap’s Managing Director/CEO, Mr Troy Hayden, said:

 “We are pleased to have commenced the Tallaganda-1 well which has the potential to deliver a resource multiple times larger than Tap’s current 2P reserves.  Success at Tallaganda-1 will also give greater certainty as to the prospectivity of the Triassic potential on the permit.”


The Operator completed a detailed assessment of the plays, prospects and leads in the permit in 2010 including the 3D seismic acquired in 2008. Further leads and prospects have been defined in the Triassic Mungaroo Formation which Tap has assessed as a 2-3 Tcf combined speculative resource on block.

Additional leads have been identified in WA-351-P in the Jurassic and Early Cretaceous, both of which are productive elsewhere in the Carnarvon Basin. Current indications are that this shallower potential is larger, but higher risk, than the Triassic in this permit. Further work will be done on these objectives.

Trinidad expects $3 Bln in energy exploration in 2012


By Linda Hutchinson-Jafar

PORT OF SPAIN, Feb 6 (Reuters) – Upstream companies operating in Trinidad and Tobago will invest $3 billion in oil and gas exploration activities this year, Energy Minister Kevin Ramnarine said on Monday.

“2012 exploration drilling will spring to life after low to moderate activity,” he said at the opening session of the Trinidad and Tobago Energy conference.

Some 15 exploration wells will be drilled this year, mainly by Canada-based companies Parex Resources and Niko Resources and by BP, he said.

Five drilling rigs are currently operating in the country while six seismic programs were continuing or starting in 2012.

Trinidad and Tobago is highly dependent on the energy sector, which contributes close to 40 percent of GDP, 40 percent of revenues and is the largest source of foreign direct investment.

Updating the status of negotiations for deep water blocks in the Atlantic, Ramnarine said discussions have concluded with BP Trinidad and Tobago and he expects sign-off soon, while talks were continuing with BG Trinidad and Tobago and BHP Billiton for deep water acreage.

Ramnarine said the country’s continuing decline in oil production was a “most worrying aspect of the energy sector.”

Oil production, which averaged 92,000 barrels per day in 2011, was hampered by a plant shutdown at the state-owned oil company Petrotrin and by maintenance activity by other small oil producers.

“Any gains in government revenue that could be realized as a result of increased oil prices were negated by falling oil production. It’s hurting the national economy and the country at a time when we should be benefitting from high oil prices,” he told the energy conference.

Oil production has declined to 100,000 barrels of oil per day (bpd) from 145,000 bpd over the last 10 years.

Ramnarine said his ministry is preparing for a road show at the end of the month in Houston to meet with representatives from 200 oil and gas companies that have expressed interest in Trinidad and Tobago.

The ministry will also promote the next deep water bid round, which will be launched next month, he said.

USA: Saratoga, McMoRan in Vermilion 16 Field JV Talks


Saratoga Resources and McMoRan Oil and Gas LLC (McMoRan) are in advanced talks regarding a potential joint venture on Saratoga’s Long John Silver Prospect at Vermilion 16 field.

While specific terms of the proposed joint venture are still being discussed and subject to confidentiality obligations, Saratoga anticipates contributing its deep rights (approximately 20,000 feet and below) to approximately 4,000 acres and access to Saratoga’s production and pipeline facilities in Vermilion 16 with McMoRan expected to contribute approximately 6,000 acres to the joint venture. The joint venture objective is expected to target ultradeep shelf Lower Tertiary (Wilcox) and Cretaceous objectives at depths of 23,000-30,000 feet subsea. All of the subject acreage is in Louisiana state waters in Vermilion Parish with water depths ranging from 5-10 feet.

The Long John Silver Prospect is situated in one of the main Lower Wilcox depositional fairways that fed McMoRan’s Davey Jones discovery on the Gulf of Mexico Shelf and the Walker Ridge Wilcox discoveries in Gulf of Mexico Deepwater.

Saratoga will retain its existing rights to all shallower objectives in the subject acreage, including all proved, probable and possible reserves, consisting of 8.7 million barrels of oil equivalent (MMBOE) of proved reserves and 18.6 MMBOE of total reserves at January 1, 2011. Additionally, Saratoga will retain the right to process its production from such shallower objectives at Saratoga’s production and pipeline facilities. Saratoga owns and operates a central production facility in Vermilion Block 16 with production capacity of 100 million cubic feet per day and a two mile pipeline to shore. Saratoga intends to continue its current development plans with respect to its shallower reserves in Vermilion 16, including drilling of development wells commencing in the first quarter of 2012.

Saratoga President, Mr. Andy Clifford, said “We are excited at the prospect of partnering with McMoRan in our ultradeep shelf play. McMoRan’s management team, under the visionary leadership of James Moffett, has established its position as a pioneer and the preeminent player in the ultradeep shelf play. We have gained valuable insights into the ultradeep Wilcox play through our involvement in the University of Texas Deep Shelf Consortium and through my years at BHP Billiton, a participant in the original Blackbeard well and a participant in the Cascade and Chinook Wilcox discoveries in Walker Ridge. We believe our Long John Silver Prospect has similar characteristics to recent high profile Wilcox successes, including McMoRan’s highly acclaimed Davey Jones well. Our 3D mapped deep shelf plays in Vermilion 16 and Grand Bay add exciting potential to our ongoing developmental drilling program.”

Phase I of the project focuses on the northern part of the greater Telemark area, which includes the Mirage and Morgus fields.
Located on Mississippi Canyon Block 941 in a water depth of 3,800 feet (1,158 meters), the Mirage field was discovered in 1998 when a well encountered roughly 87 feet (27 meters) of hydrocarbons in two sands. The Morgus field is located on Mississippi Canyon Block 942 in 4,304 feet (1,312 meters) of water, and was discovered when drilling encountered approximately 55 feet (17 meters) of net pay.
In an effort to cut costs, ATP decided to jointly develop these fields due to their close proximity. Combined, Mirage and Morgus hold estimated recoverable reserves of 190 Bcf (5 Bcm).
In 2008, the West Sirius semisub drilled three wells on the Mirage and Morgus fields and reached a total depth of 5,900 feet (1,798 meters) in 3,927 feet (1,197 meters) of water.
To develop the Mirage field, Technip received a contract for the flowlines, risers, jumpers and subsea structures. The contract covered engineering for the installation, welding and installation of two steel catenery risers and two oil and gas export flowlines; fabrication and installation of subsea structures and jumpers and pre-commissioning of the project.
Mirage is operated by ATP, which owns a 25% interest; Statoil owns the remaining 75% interest. Morgus is operated by ATP, but Statoil owns 100% of the interest.
Phase II of the project focuses on the Telemark field. Telemark is situated in a water depth of 4,300 feet (1,311 meters) on Atwater Valley Block 63. ATP acquired the field in 2006 and owns 97% interest; BHP Billiton holds 1% interest; Chevron holds 1% interest; and Eni holds the remaining 1% interest.
The field was discovered in 2003 in the southern part of the greater Telemark area when exploratory drilling encountered 140 feet (43 meters) of hydrocarbons in the Miocene sands. The Telemark field was deemed commercially viable shortly after, and ATP began field development preparations.
Situated 7 miles south of the Mirage and Morgus fields, Telemark originally was designed to have its own production hub, a MinDOC II, but the company decided to tie-back the field’s subsea well to the ATP Titan, as well. This development will result in an increase in production rates through ATP Titan in 2010 and 2011.
In May 2009, Bluewater Industries received a contract for the field’s development. The contract covers the design and manufacture of one high-pressure flexible riser measuring 2 miles (3 kilometers) long, and engineering for the installation and welding of one oil and gas production flowline approximately 13 miles (21 kilometers) long. The contact also includes installation of a flowline and associated riser with an option to install an umbilical; fabrication and installation of subsea structures and a jumper; and pre-commissioning of the project.
ATP Titan
In 2007, ATP decided to develop the Telemark area with a floating, drilling and production triple-column spar, the ATP Titan, since accessible infrastructure wasn’t nearby. The MinDOC, a deep draft floating platform, is comprised of three columns linked by pontoons, boasting a higher load capacity and enhanced stability than previous designed semisubmersibles or spars.
In 2007, construction of the ATP Titan MinDOC commenced with construction slated to end in the third quarter of 2009. The facility has a design capacity of 25 Mbopd and 60 MMcf/d (2 MMcm/d) and incoporates six dry tree wellheads with three pairs of future subsea flowlines. Mustang Engineering received a contract to provide detailed engineering and procurement support for the topsides production facilities on the ATP Titan.
Towards the end of 2009, ATP Titan was moored at the Mirage and Morgus fields to complete the drilling of three wells to vertical depths of 14,500 to 17,250 feet (4,420 to 5,258 meters). The vessel will serve as the production platform for the life of the fields’ reserves. Then, ATP Titan will move to the Telemark field to recover its remaining reserves once the vessel has finished producing from the Mirage and Morgus fields.
First production from the Telemark Hub commenced on March 28, 2010, and the vessel has an estimated life span of 40 years.
Future Exploration
A fourth field that is 100% owned and operated by APT — Oasis — is located on Mississippi Canyon Block 943, and may be tied-back to the platform, pending exploration results.


BP Announces Significant Resource Extension of Mad Dog Field in Gulf Of Mexico


Release date: 07 September 2011

BP announced today the drilling of a successful appraisal well in a previously untested northern segment of the Mad Dog field in the US Gulf of Mexico.


The well results confirm a significant resource extension for the Mad Dog Field complex, which includes the existing field, in production since 2005, and appraisal drilling of the Mad Dog South field in 2008 and 2009. Pending confirmation through future appraisal drilling, the total hydrocarbons initially in place in the Mad Dog field complex are now estimated to be up to four billion barrels of oil equivalent.

The well, drilled by BHP Billiton on behalf of the unit operator BP, is located on Gulf of Mexico Green Canyon block 738 approximately 140 miles (225 kilometres) south of Grand Isle, LA., in about 4,500 feet (1,371 metres) of water. The well encountered about 166 net feet (50 metres) of hydrocarbons in the objective Miocene hydrocarbon-bearing sands and discovered an oil column of more than 300 feet (91 metres).

“With these additional hydrocarbon resources north of the main field, Mad Dog has been firmly established as a giant field in BP’s Gulf of Mexico portfolio, rivalling Thunder Horse in size of resource,” said Bob Dudley, BP group chief executive. “Working with the industry and regulators, we will apply our enhanced standards of safety, reliability and compliance to all of our Gulf activities as we continue to provide important jobs and energy to the nation.”

BP maintains a 60.5 per cent working interest in Mad Dog. BHP Billiton has a 23.9 per cent interest, Chevron Corporation, through its subsidiary Union Oil Company of California, has a 15.6 per cent interest.

Due to the materiality of the Mad Dog South finds in 2009, BP has been advancing development options to increase production from Mad Dog by adding another spar production facility with a production capacity of 120,000–140,000 barrels of oil equivalent per day (boed).

“Coupled with the recent exploration success at the discovery at the Moccasin prospect, located in Keathley Canyon, the Mad Dog result re-emphasizes the exploration and development potential of the Gulf of Mexico and the region’s ability to continue to deliver material projects for BP,” Dudley added.

On Sept. 6, 2011 Chevron Corporation announced the Moccasin discovery in the Lower Tertiary play on Keathley Canyon block 736. BP has a 43.75 per cent working interest in the Moccasin prospect. The prospect is operated by Chevron U.S.A. Inc., also with a 43.75 per cent interest, and the co-owner is Samson Offshore Company with 12.5 per cent interest.


  • The Mad Dog Field started production in 2005 and utilizes a truss spar platform, equipped with facilities for simultaneous production and drilling operations. The facility is designed to process 80,000 barrels/day of oil and 60,000 standard cubic feet/day of gas.
  • Oil and gas is transported to existing shelf and onshore interconnections via the Mardi Gras Transportation System.
  • BP is one of the largest producers of oil and gas in the US Gulf of Mexico with net production of over 250,000 boed. BP is progressing eleven Gulf of Mexico projects: Atlantis Phases 2 and 3, Kaskida, Mars B, Galapagos, Na Kika Phases 3 and 4, Freedom, Mad Dog Phase 2, Mad Dog North and Tiber.
  • Major BP developments in the deepwater Gulf of Mexico include: Pompano, 1994; Marlin, 2000; Horn Mountain, 2002; Na Kika, 2003; Holstein, 2004; Mad Dog, 2005, Atlantis, 2007, Thunder Horse 2008.
