O&G reserves in the South China Sea: Tempers Flaring
Geopolitical location, an abundance of fish and huge O&G reservoirs make the South China Sea (SCS) particularly attractive to the countries that all lay claim to parts of it, such as China, Taiwan, the Philippines, Malaysia, Brunei, Vietnam, Indonesia, Singapore, Thailand and Cambodia. While the Chinese National Offshore Oil Company (CNOOC) estimates the SCS holds around 125 billion barrels of oil and 500 trillion cubic feet of natural gas in uncorked reserves, the U.S. Energy Information Administration (EIA) estimates the SCS contains only approximately 11 billion barrels of oil and 190 trillion cubic feet of natural gas in proven and probable reserves, although the EIA admits this figure could increase pending geological surveys of peripheral locations.
Brazil Exploration Review 2013
The auction of Libra pre-salt field, forecast to contain between 8 and 12 billion barrels boe in recoverable reserves, was Brazil's first bidding round in the pre-salt area, and failed to meet the high expectations placed on it by the Brazilian government, yet the government, the ANP (National Oil Regulator) and Petrobras are highly satisfied with the results because they managed to attract important and experienced partners in Shell and Total, along with the high rolling Chinese companies. Despite a nine-month global publicity campaign and predictions of fervent bidding by as many as 40 firms, the license was awarded to the only consortium to register a bid. Another controversial state controlled company PPSA will oversee the contract’s implementation, having both voting and veto rights.
The Pelotas Basin Oil Province Revelation
Pre-salt and post-salt exploration in the Campos, Santos and Espirito Santo basins along Brazil’s southeast margin has yielded extraordinary success, while their southern sister, the relatively unknown Pelotas basin, has seen little attention for over the last ten years, despite displaying clear direct hydrocarbon indicators in previous seismic surveys. However, a new 2D seismic program acquired in 2013 by Spectrum Geo Multi-Client is revealing new evidence for sand-rich systems and oil plays, making the deepwater Pelotas basin an excellent choice for blocks to be nominated in Brazil’s upcoming 13th bidding round, which may take place sometime in 2014.
OTC Brasil 2013 – Opening Day Highlights
The Offshore Technology Conference Brasil 2013, was only the 2nd time the conference was held in Rio de Janeiro, Brazil, yet it was obvious that the conference had grown in size and scope. During the 3 days a long list of interesting and even some exiting Technical Sessions took place, addressing everything from Local Content to the latest in Deepwater Technology. After the Opening Session on Tuesday October 29th, which was presented by OTC and IBP (Brazilian Petroleum Institute) senior executives and the OTC Brasil Technical Program Chairman, the main event was the Topical Luncheon on Planning and Management of Offshore Oil Opportunities in Brazil: Petrobras Perspective, which had as its speaker Petrobras CEO Maria das Graças Foster.
SeaBED-class AUVs – The Deepwater Imager
The SeaBED AUV, developed by WHOI scientist Hanumant Singh and colleagues, is an AUV that can fly slowly or hover over the seafloor to depths of 6,000 feet (2,000 meters), making it particularly suited to collect highly detailed sonar and optical images of the seafloor. SeaBED flies about 8 feet (2.5 meters) above the seafloor, flashing its strobe light and snapping a photo every three seconds. It maintains a constant altitude and speed of a ½ knot. Over the last seven years SeaBED-class AUVs have shown their versatility on missions ranging from shallow coral reef surveys to searches for deep-sea hydrothermal vents, in environments ranging from the open ocean to the dense ice cover of the Arctic.
Ultra-Deepwater Subsea UHP Water Jet
There is a wide array of equipment used in deepwater oil and gas E&P, many are well known, others less so and some are simply unique. Deepwater subsea ultra-high pressure water (UHP) jets belong to this last category. Chukar Waterjet is the only water jet manufacturer in the world that offers UHP water jets that operate in the ultra-deepwater subsea environment, down to depths of up to 10,000 feet (3000 meters). Chukar’s deepwater subsea water jet system has numerous applications for deepwater emergency response operations, salvage operations, and rapid de-mobilization operations. It can cut steel up to 250 mm thick and quickly blast away concrete weight coatings, corrosion and marine growth at pressures up to 55,000 psi (3800 bar).
Subsea Connection Systems - FMC's UCON System
Subsea oil fields are dependent on a large amount of connections between various kinds of subsea equipment in order to function. They allow umbilicals, flowlines, risers and rigid jumpers to connect to manifolds, x-mas trees, BOPs, pipelines and riser bases. These connections need to be absolutely safe and reliable as connection problems can cause a series of problems in operating subsea equipment which may affect exploration and production only a little or cause these to partially or completely stop. On top of that subsea connection failures may also cause oil spills or gas leakage in the environment in small or large amounts, driving operators and subsea service and equipment providers to invest heavily in research regarding ideal connection manufacture…
Portuguese Investment in Brazil’s Pre-Salt
Galp Energy, which is Portugal’s major O&G operator, is aiming at increasing its investments in Brazil through acquisition of new block during Petrobras’ pre-salt bidding round next October. Galp is already considered a preferred partner by Petrobras as can be seen by the fact that Galp currently partners Petrobras in four deepwater pre-salt blocks in the Santos Basin, with the biggest blocks being Lula and Cerambi, both large pre-salt plays, which are producing. Earlier this year Galp again partnered Petrobras in acquiring nine blocks in the Parnaíba, Potiguar and Barreirinhas Basin, during the 11th bidding round which mainly encompassed block along Brazil’s Northeast Coast and Equatorial Margin.
R/V Meteor – German Research Ship off Brazil
The R/V Meteor research ship arrived in Fortaleza, Ceara, on Brazil’s Equatorial Margin last Friday, June 28th. The Meteor which has a complement of 30 scientists of different nationalities, including one Brazilian, left port on Monday as it begins another Atlantic crossing to Namibia in West Africa, where it is due to arrive on July 29th. Along the voyage the ship will be collecting samples and data from deep waters, to be analyzed by a multidisciplinary team of researchers, composed of chemists, biologists and physicists. The only Brazilian aboard is Marcio Pereira, a 63 year old professor of Oceanographic Physics from the Geophysics department of the Federal University of Rio Grande do Norte (UFRN), whose studies will be concentrated in variations of marine currents.
World's Largest PLV
The extraordinary growth of the world subsea market over the past decade and the raising demand for O&G plays in deep and ultra-deep waters to begin production and for the deep and ultra-deep water drilling to continue in Brazil, at the GoM and in WA, has led to the development of a range of new offshore field development and support vessels, including a large new pipelay vessel, currently laying its pipelines along the GoM. Since 2012 Saipem has been operating the MV CastorOne, it is a ship-shaped pipelay vessel with an overall length of 330 m (excluding stinger) and DP 3 capable. The CastorOne was classed by ABS (American Bureau of Standards) and is also Ice classed, capable of berthing 700.
Subsea Well Response Project to be launched in Brazil
With the continued increase in deepwater drilling off the coast of Brazil, it is good to see that Petrobras, Brazil’s national operator, will soon have a well containment device ready for immediate deployment in case of a deepwater blowout such as was experienced in the Deepwater Horizon tragedy at the GoM. According to a Petrobras drilling inspector who prefers to remain anonymous, the Brazilian super-major player believes that their well drilling and completion systems are totally reliable as long as their safety procedures are followed, however, they are taking no chances and have joined forces with other major operators to increase drilling, completion and production safety standards worldwide.
A Monster Named Libra
Back in 2009 I asked a good friend of my late father, who happened to be a long time Petrobras geologist, if he really knew the full potential of the pre-salt, after a while he looked up and said no not really, I know there are big fields out there, probably up to 10 billion boe in some reservoirs, possibly much more... Well, Petrobras kept on drilling and when Libra was found northeast of the Lula field (5 to 8 billion barrels boe), in 2010, the expectations ran high. Maybe 3.7 billion boe, maybe 15 billion boe. Probably 7.9, those are the numbers the ANP had in 2010. By May 2011 the ANP was downgrading it to 5 billion barrels boe.
