NPRA asks court to overturn EPA's E15 waiver

The National Petrochemical & Refiners Association and two other oil and gas associations petitioned a federal appeals court on Jan. 3 to review and overturn the US Environmental Protection Agency's decision allowing fuels with up to 15% ethanol to be used in model year 2007 or newer vehicles.

The Western States Petroleum Association and Independent Liquid Terminals Association joined NPRA in the legal challenge. "The organizations challenging EPA's decision believe the agency has acted unlawfully in its rush to allow a 50% increase in the amount of ethanol in gasoline without adequate testing and without following proper procedures," NPRA Pres. Charles T. Drevna said on Jan. 3. "As a result, we had no choice but to take this issue to court."

EPA issued the waiver on Oct. 13, 2010, in response to a petition by Growth Energy, an ethanol advocacy group. The US Appeals Court for the District of Columbia upheld EPA's action on Dec. 21. NPRA said it and the two other groups will argue in their lawsuit that EPA does not have legal authority under the Clean Air Act to approve a partial waiver allowing the use of E15 in some engines but not in others.

It said that it also will argue that EPA based its partial waiver decision on new data submitted to the public rulemaking docket on the day before it announced the partial waiver decision, thereby providing no time for stakeholder review or meaningful public comment which the federal Administrative Procedure Act requires.

NPRA, along with recreational, work equipment, and transportation engine manufacturers, have expressed concern that E15's introduction without more complete tests potentially could damage engines.

Newfield, EOG terminate Marcellus shale deal

Newfield Exploration Co. and EOG Resources Inc. mutually agreed to terminate a deal for Newfield to buy Marcellus shale development assets in Bradford County, Pa., from EOG for $405 million.

Japan's November oil imports rise 10.8% on year

Japan's Natural Resources and Energy Agency (NREA) said the country's imports of crude oil in November rose 10.8% from a year earlier to 122.09 million bbl.

It also marked the first sequential increase in 2 months, officials said.

Oil shipments from the Middle East accounted for 86.2% of Japan's total imports, down 3.8%, said NREA, a division of the Ministry of Economy, Trade, and Industry.

Saudi Arabia remained Japan's chief supplier of oil, exporting 38.24 million bbl, down 0.4%. The UAE followed with 22.14 million bbl, down 3.8%, while Qatar, which supplied 15.1 million bbl, rose 24.6%.

NREA earlier reported Japan's oil imports in October fell 5.8% from a year earlier to 105.23 million bbl, marking the first decline in 4 months.

It said oil shipments from the Middle East still accounted for 86.3% of total imports, down 3.5%.

Saudi Arabia remained Japan's biggest oil supplier, exporting 28.12 million bbl, down 4.5%; with the UAE second at 22.33 million bbl, down 19.3%; followed by Qatar, with 11.01 million bbl, down 20.1%.

According to the US Energy Information Administration, Japan was the second-largest net importer of oil in the world after the US in 2009, having imported about 4.7 million b/d.

"Japan is currently looking towards Russia, Southeast Asia, and Africa to geographically diversify its oil imports," EIA said, adding 80% of Japanese oil imports originate in the Middle East, up from 70% in the mid-1980s.

Ivanhoe discovers more Sichuan gas in China

Ivanhoe Energy Inc. said China subsidiary, Sunwing Energy Ltd., discovered natural gas with its Yixin-2 well in southwest China on the Zitong block. Gas flowed at rates of up to 13 MMcfd, and averaged 9-10 MMcfd during an initial 24-hr test.

Gas is flowed from the Xu-4 formation, a well established gas-producing formation. Ivanhoe said the rates recorded demonstrate the discovery's strong potential, and Sunwing plans to continue with further development of the Xu-4 formation and other structures in the Zitong block (OGJ Online, Nov. 2, 2010).

Sunwing's 659,840-acre holding on Zitong block is in the Sichuan Province. Sunwing operates the Zitong exploration block and holds a 90% contractor interest in a petroleum contract with PetroChina Co. Ltd. Japan's Mitsubishi Gas Chemical Co. holds 10% contractor interest.

Technical teams from Sunwing and PetroChina are working to develop a strategy to evaluate the Yixin structure, as well as the potential for further discoveries elsewhere on the Zitong block, Ivanhoe said.

Llanos wildcat making 10,440 b/d of light oil

Petrominerales Ltd., Bogota, said its Yatay-1 exploratory well on the Guatiquia block in Colombia's Llanos basin is making 10,440 b/d of 43° gravity oil on natural flow from the Lower Sand 3 formation.

Logs at Yatay-1 indicate 114 ft of potential net oil pay in the Lower Sand-3 formation and 17 ft of potential net oil pay in the Guadalupe formation.

An electrical submersible pump was installed in the well after perforating a 10-ft section at the top of the Lower Sand-3 formation. Over the last 17 hr the well has produced on natural flow through a 1-in. choke, at a rate of 10,440 b/d with less than a 0.1% water cut.

The company is evaluating the potential for additional Yatay follow-up locations incorporating the well results and recently completed Guatiquia 3D seismic survey. Yatay-1 is the first well into a new, seismically defined structure downdip from the Candelilla structure and across the bounding Candelilla fault. The Candelilla structure produced more than 7.3 million bbl of light oil in 2010 from the Lower Sand-3 and Guadalupe formations.

The rig will move to the Candelilla-5 location targeting the Guadalupe formation that is currently producing in Candelilla-4. Meanwhile, the Cardenal-1 and Celeste-1 wells are drilling since early December 2010 on the Corcel block, and results are due by late January.

Meanwhile, Petrominerales' Borugo-1 exploratory well on the Rio Ariari heavy oil block in the Llanos basin is cased for tests after logs indicated 35 ft of potential net oil pay in the Mirador formation. Total depth si 5,260 ft.

Borugo is testing a play concept distinct from the company's Mochelo-1 and Rio Ariari-1 discovery wells.

Desire drills another dry hole off Falklands

Desire Petroleum PLC said its 25/5-1 well on the Dawn/Jacinta prospect reached a depth of 1,313 m, but drilling and wireline logging data show no hydrocarbons have been found.

"The well will now be drilled to the planned total depth around 1,670 m to evaluate the deeper Dawn Prospect," Desire said, adding that the reported results are based on the work of Senergy (GB) Ltd.

The announcement will likely be greeted with cheers in Argentina, which has long complained of British-led efforts to discover oil and gas in the region around the Falklands Islands, over which the two nations went to war in the 1980s.

Argentina recently passed a law includes the disputed islands as part of its Tierra del Fuego province, and the Latin American nation also declared the Desire drilling illegal.

In October, Desire Petroleum disappointed investors by announcing its 14/15-1 well on the Rachel prospect in the remote North Falkland basin found thick, porous reservoir rock but no hydrocarbons and would be sidetracked (OGJ Online, Oct. 15, 2010).According to industry observers, Desire's failure on the Jacinta prospect will put pressure on Rockhopper Exploration PLC with its next well, aimed at proving an extension to the Sea Lion find reported in May.

At the time, Rockhopper said its Sea Lion discovery in the North Falkland basin in the South Atlantic found an estimated 170-242 million bbl of recoverable medium-gravity crude oil as "the first contingent oil resource in the Falklands" (OGJ Online, June 7, 2010).

Rockhopper plans to start drilling next month using the Ocean Guardian rig currently being used by Desire, which was named after HMS Desire, the British ship that claimed to have discovered the Falklands in 1592.

Apache starts production from Balboa in gulf

Houston independent Apache Corp. started producing oil and natural gas from Balboa field in about 3,350 ft of water on East Breaks Block 597, 130 miles south of Galveston, Tex. The field is a one-well development with a 6-mile tieback to the Anadarko Petroleum Corp. operated Boomvang spar on East Breaks Block 643.

Production from the well started on Dec. 28.

Apache said initial gross flow rates have stabilized at about 30 MMcfd of gas and 1,400 bo/d from an oil-bearing sandstone reservoir with a gas cap. The company noted that the well is completed near the crest of the structure to optimize overall hydrocarbon recovery and is expected to initially produce gas and liquids with increasing liquids and decreasing gas volumes throughout the life of the field.

Apache assumed operatorship of Balboa with the acquisition of Mariner Energy Inc. in November 2010.

The company holds a 50% interest in the block with the other 50% held by Marubeni Oil & Gas (USA) Inc., according to US Bureau of Ocean Energy Management, Regulation, and Enforcement records.

Seadrill buying two ultradeepwater semis

Seadrill Ltd. agreed to acquire two ultradeepwater semisubmersibles currently under construction at Jurong Shipyard Pte. Ltd. in Singapore for $1.2 billion, Seadrill announced on Jan. 3.

The SeaDragon I and Seadragon II are expected to be delivered in this year's first and fourth quarters, respectively.

The SeaDragon I had a 5-year contract, but Seadrill said the contract is under discussion because the scheduled delivery was delayed. There is no contract for the Seadragon II.

The dynamically positioned rigs will be capable of drilling in 10,000 ft of water and have total vertical drilling depth capacity of up to 35,000 ft. The rigs each have a single derrick with dual pipe handling and offline stand building capabilities, Seadrill said.

Vantage Drilling Co. oversaw construction services for SeaDragon I and SeaDragon II, which are nearing completion. Vantage said a customer, which it did not identify, had terminated Vantage's management contract for the rigs.

Paul A. Bragg, Vantage chairman and chief executive officer, said, his company considered buying the rigs but decided against it. "We were not prepared to take excessive risks in terms of our offer," Bragg said.

On Dec. 29, Vantage announced its Platinum Explorer ultradeepwater drillship commenced operations for ONGC in India. Platinum Explorer is contracted for 5 years with corresponding estimated revenues of $1.1 billion.

Vantage owns four Baker Marine Pacific Class 375 ultrapremium jack up rigs and a drillship.

Petrobras submits Tupi, Iracema declaration

Petroleo Brasileiro SA (Petrobras) submitted to Brazil's National Petroleum Agency (ANP) a declaration of commerciality for the presalt oil and gas fields in the Tupi and Iracema areas of Block BMS-11 in the Santos basin off Brazil.

Petrobras proposed the names Lula and Cernambi for the fields in the Tupi and Iracema areas, respectively.

In its commerciality declaration, Petrobras reports that Lula contains 6.5 billion boe and Cernambi contains 1.8 billion boe of recoverable oil and gas.

The oil gravity is 28° in Lula and 30° in Cernambi.

Petrobras notes that Lula will be the first supergiant oil field in Brazil with recoverable volumes more than 5 billion boe, while Cernambi is among the top-five giant fields in Brazil.

Along with the commerciality declaration, Petrobras also submitted to ANP the final report on the evaluation plan and the development plan for the two fields.

Petrobras drilled the discovery well for the area in October 2006 and since then has drilled 11 wells in the area. In April 2009, the company began an extended well test in Tupi that provided information for estimating recoverable volumes and formulating a development plan.

Pilot production from the Tupi area began in October (OGJ Online, Oct. 28, 2010).

Petrobras is the operator of the block with a 65% interest. Block partners are BG Group 25% and Portugal's Galp Energia 10%.

Denbury commences CO2 flood at Hastings

Denbury Resources Inc. in December completed the last section of the 24-in., 320-mile Green Pipeline for transporting carbon dioxide from Donaldsonville, La., to oil fields in Texas and on Dec. 16 started injecting CO2 for enhancing oil production from Hastings oil field in Brazoria County.

The Green line has a designed capacity to transport 800 MMcfd of CO2 and at Donaldsonville the pipeline receives CO2 from Denbury's NEJD CO2 pipeline that also transports CO2 from the company's Jackson Dome, Miss., CO2 source field to its enhanced oil recovery projects in Mississippi and Louisiana. The company also expects to eventually tie in anthropogenic CO2 sources to the Green line.

In addition, Denbury recently received a US Army Corps of Engineers permit for facility construction at Hastings and anticipates receiving a permit for facility construction at Oyster Bayou oil field, Chambers County, Tex., in January 2011.

Denbury started CO2 injection in Oyster Bayou in June 2010.

Denbury in a December presentation estimated that Hastings contains 70-100 million bbl and Oyster Bayou contains 20-30 million bbl of recoverable tertiary oil.

Chinese gas plant installs treating in eastern plant

Sinopec's 1.27-bcfd Puguang natural gas plant in China's eastern Sichuan province is using Black & Veatch's Interstage Cooling technology to remove H2S and CO2 from feed gas produced from Puguang field.

The Puguang gas plant produces up to 8,400 tonnes/day and 3 million tonnes/year of sulfur. The processing plant removes virtually all the H2S, which comprises nearly 15% of the raw gas, and converts it to elemental sulfur. It also reduces CO2 to 3 vol % from 10 vol %, according to the Black & Veatch announcement. The company is providing process design engineering, technology licensing, and field support services as part of a sour-gas purification and sulfur-recovery scheme.

The giant gas field, with proven original gas in place of more than 12.5 tcf, was discovered in 2003 in the eastern Sichuan basin. In addition to the Puguang gas plant, Black & Veatch says it has recently provided process engineering and technology licensing for PetroChina's Longgas sour-gas field development in Sichuan province, a field discovered in 2006.
