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: Shell Sets World Record for Deepest Subsea O&G Well at Perdido Development

image

Shell Oil Company is now producing oil from the world’s deepest subsea well at its Perdido Development, utilizing advanced technology to lead the way in increasing the company’s ability to produce more domestic oil and gas resources.

The well, at 9,627 feet below the water’s surface, is located in the Tobago Field 200 miles southwest of Houston in the ultra-deep water of the Gulf of Mexico. Tobago is jointly owned by Shell (32.5%, as operator), Chevron (57.5%), and Nexen (10.0%) and is one of three fields producing through the Perdido drilling and production platform.

Tobago breaks the world water depth record for subsea production, previously held by another field in the Perdido Development, the Silvertip field at 9,356 feet of water.

“Energy is fundamental to global economic growth. Providing this energy must be met practically, safely and in an environmentally responsible manner,” said Marvin Odum, Upstream Americas Director. “Through our highly skilled workforce and cadre of global geoscientists, Shell has applied its advanced seismic and drilling technologies at Perdido to produce additional sources of oil and gas.”

Moored in about 8,000 feet of water, the Perdido platform is jointly owned by Shell (33.34%), BP (33.33%) and Chevron (33.33%) and is the deepest drilling and production facility in the world with a capacity to handle 100,000 barrels of oil per day and 200 million standard cubic feet of gas per day. From Perdido, Shell accesses the Great White, Tobago, and Silvertip oil and gas fields through subsea wells directly below the facility and from wells up to seven miles away. At its peak, Perdido can produce enough energy to meet the needs of more than two million US households. Shell operates Perdido and its satellite fields on behalf of partners Chevron, Nexen, and BP.

This world-class project began with the 1996 lease sale when the technology to develop hydrocarbons at Perdido’s water depth did not yet exist. By the time the final investment decision for commercial development was made in October 2006, Shell had pioneered several technological firsts which allowed the company to proceed with ultra deepwater oil and gas production. Development drilling began in July 2007, five years after the discovery of hydrocarbons. Perdido produced its first oil and gas on March 31, 2010.

Perdido Technical Facts and Firsts

*Deepest water depth record for an offshore oil drilling and production platform.

*First water injection in 8,000 feet of water in the Gulf of Mexico (Great White GB001) helps push oil through the reservoir, from the injector wells to the production wells.

*First commercial production from the Lower Tertiary geological formation, which many see as the next big opportunity in deep water.

*Deployment of an innovative subsea separation and boosting system that compensates for the low-pressure reservoir and about 2,000 psi of backpressure from the wells. The system includes five specially designed 1,500-horsepower electric pumps embedded in the seafloor to boost production to the surface.

*First spar with direct vertical access wells and production hardware on the seafloor at a depth of more than 8,000 feet.

*Perdido weighs 50,000-tons and sits in water six times deeper than the height of the Empire State Building.

*The entire Perdido project has achieved 13 million man-hours without a lost-time injury, testifying to the effectiveness of the safety regimes put in place by the construction and operating teams.

Tour the Perdido platform, spar and underwater equipment with this fly-by animation.

Shell has been a leader in deep-water exploration and production for the last 30 years. Perdido in the Gulf of Mexico is one of our most challenging deep-water projects. Shell has a 35% interest in the project and is the operator. Perdido is in a water depth of some 2,450 metres (8,000 feet). First production from Perdido was on March 31, 2010.

Technology

Perdido, moored in ~2,450 metres (8,000 feet) of water, is the world’s deepest direct vertical access spar. The spar acts as a hub for and enables development of three fields – Great White, Tobago, and Silvertip. It gathers, processes and exports production within a 48-kilometre (30-mile) radius. Tobago, in ~2,925 metres (9,596 feet) of water, will be the world’s deepest subsea completion. The Perdido platform peak production will be 100,000 barrels of oil equivalent a day.

Environment and society

Social and environmental responsibility is a central pillar of Shell’s operations. Shell’s Gulf of Mexico operations have a long association with the city of New Orleans, and this is reflected in the contribution the company made to many recovery programmes after Hurricane Katrina. The Shell Coming Home campaign and sponsorship of the New Orleans Jazz and Heritage Festival – a key event in the city’s on-going recovery – helped build confidence in the city’s future. Shell is also involved in projects such as wetlands restoration on the Texas/ Louisiana coast.

Current developments

The Perdido spar was constructed by Technip in Pori, Finland and began its 13,200-kilometre (8,202-mile) journey to Texas in May 2008, arriving in the Gulf of Mexico in August 2008. The 170-metre (555-foot) cylindrical spar was secured to the sea floor and Shell completed the installation of the drilling and production platform on top of it. Around 270 staff living on the platform and an adjacent floating hotel, or flotel, completed the commissioning and hook-up required to produce first oil.

There are 22 direct vertical access wells from the spar, with an additional 13 tiebacks from subsea completions. The Perdido hull is nearly as tall as the Eiffel Tower and weighs the same as 10,000 large family cars.

The Noble Clyde Boudreaux platform drilled the production wells. We set a world record in December 2008 with the deepest completed offshore production well at about 2,852 metres (9,356 feet) below the water’s surface. Another well currently being drilled in the Tobago field will go deeper at around 2,925 metres (9,627 feet).

Niko to Begin Drilling at Block 2ab Offshore Trinidad in September 2011

image

Canada’s Niko Resources and Britain’s Centrica will invest $70 million in three offshore exploration wells this year in Trinidad and Tobago, the Caribbean’s leading oil and natural gas producer, officials said on Wednesday.

The two companies, along with Trinidad and Tobago’s state-owned integrated energy company Petrotrin, are joint venture partners in an offshore region known as Block 2ab.

Ajith Muralidharan, a manager at Niko Resources, said drilling is scheduled to begin in September and that surveying so far had “shown prospects with substantial potential.”

The investment comes as Trinidad and Tobago seeks to lure investment and increase oil and natural gas output in its vital energy sector, which accounts for 45 percent of the country’s gross domestic product and 60 percent of its foreign exchange earnings.

Government statistics show oil production has fallen steadily over the last decade from 145,000 barrels a day to 100,000 bpd over the last 10 years.

Natural gas reserves declined from 22 trillion cubic feet (TCF) to just over 14.5 TCF during the same period.

Trinidad and Tobago’s Energy Minister Carolyn Seepersad- Bachan welcomed the drilling plan as a sign exploration may be poised to pick up again after falling over the past two years largely because of high drilling costs and the onset of the global recession.
