June 16, 2013

Untitled
The increase in exploratory O&G programs around the world and specifically the deepwater exploration programs being undertaken at the GOM, in West Africa and Brazil has caused major improvements and new technologies and materials to be employed in subsea equipment, such as BOPs, wellhead systems, risers, manifolds, flowlines, drilling fluids among others. GE´s VetcoGray has developed an interesting seal technology for its subsea wellheads. Named MS seal, it is based on Metal-to-metal sealing technology. All VetcoGray subsea wellheads use metal-to-metal sealing technology, which is superior to elastomer options because it prevents inevitable heat and corrosive fluids from damaging seal integrity. Both the wellhead and hanger have a sealing area of parallel wickers.

Lankhorst Ropes Thunder Hawk FPU go M moored with Gama rope reduced
With the increase in deepwater O&G exploration, the demand placed on mooring ropes for MODUs (Mobile Operating Drilling Units) has increased dramatically. Rope manufacturers have been developing products based on new materials and also adapting their manufacturing processes to accommodate new materials and more stringent requirements. In some deepwater plays mooring ropes will be going down to 2,000 or even 3,000 meters, which places massive stress on the ropes, due not only to its length and weight but also due to the action of subsea currents, ship movement caused by surface waves, currents and wind. Dutch rope manufacturer Lankhorst Ropes…

Ultra-Deepwater AUVs and ROVs show their value by finding AF 447s Fuselage

June 16, 2013

untitled
If the earlier searches for the debris had made a more intensive use of ultra-deepwater AUVs, finding the sunken fuselage, the black boxes and voice recorders may have taken considerably less than two years. However we must also consider that the total estimated search area was huge. The first idea of using submarines, just wasn´t enough with the extreme depth involved (3,900 meters). France had announced last February that it would begin the 4 phase of its search for the AF 447 debris, somewhere over 700 km from the north coast of Brazil, beyond the remote islands of Saint Peter and Saint Paul, a notorious shipwreck location. The new effort aimed to find the downed Airbus A330-200, which crashed on May 31 2009, killing all 228 passenger and crew members as it flew from Rio to Paris.

Rising Environmental Concerns greet the Woods Hole Group in Brazil

June 16, 2013

The Woods Hole Group (WHG), headquartered in East Falmouth, Cape Cod, Massachusetts, recently announced the launching of its first office in Brazil over increasing concerns about possible environmental problems which may be triggered by the continued increase in O&G exploration in Brazil. There are no local environmental organizations in Brazil that can match the experience, expertise and credibility of the WHG in terms of providing comprehensive solutions to challenges and consequences of environmental problems. Although Brazil´s official environmental impact agency “IBAMA” is undoubtedly experienced and even efficient in its environmental impact monitoring, it is still a government agency and therefore it can hardly be considered completely independent.

Deepwater Umbilical Challenges in Brazil and Worldwide

June 16, 2013

In the past all umbilicals were made of thermoplastics, used mainly for transport of hydraulic fluids to open or close valves, with separate hoses connecting to each valve on a subsea tree. As the deepwater production increased, concerns over possible failures on thermoplastic umbilicals mounted, triggering the development of the steel tube umbilical. Efficiency and reliability are the keys for deepwater umbilicals. The modern subsea umbilical used by the O&G industry provides transmission of electric and fiber optic signals, electrical power, hydraulic fluids, and injection of chemical fluids from the surface to the seabed through electric and/or fiber optic cables encased in thermoplastic and/or steel tubes.

Water Injection improving deepwater and mature field EOR

June 16, 2013

Enhanced Oil Recovery (EOR) can increase the volume of recovered oil from a well mainly through the use of two distinct techniques. One is water injection, which is increasingly being used in mature fields and another is CO2 injection which is mostly used in deepwater fields and according to Petrobras will be extensively used at many of the pre-salt fields in Brazil, as these fields usually contain significant amounts of CO2 along with oil and gas. These are secondary production processes. The production process always refers to oil that is recovered naturally from a producing well, that is without the use of pressure or flow stimulants, such as water or CO2.

Advanced-Subsea Deep in the Pre-salt

June 16, 2013

diapositive
With the great demand for deepwater subsea equipment and services,  for deployment at the new pre-salt plays and other post-salt deepwater plays from Petrobras and other O&G operators in Brazil, various companies specializing in deepwater equipment and services are setting up or have already set up shop in Brazil. At this point there are very few totally national companies that have the capacity to offer deepwater E&P support services and basically there are no 100% national companies with the capacity to manufacture deepwater support equipment. That will undoubtedly change along the next decade but for now until the foreseeable future these equipments and services will be provided by foreign companies through their Brazilian subsidiaries.

subseaequipmentservicesdemandcontinuesgrowinginbrazil
New discoveries and the development of deepwater and ultra-deepwater pre-salt increases the demand for subsea equipment and service providers, attracting various international and local companies to compete for subsea contracts for the Brazilian offshore.The deepwater scene is in full swing in Brazil, with major projects being developed by various operators and national operator Petrobras. All these projects require a multitude of subsea equipment and subsea services, which accounted for a steady growth in subsea equipment and service providers from around the world setting shop in Brazil. Companies that have a history of quality equipment and services usually have an advantage when disputing these contracts, but the final product and services price is also a major issue.

Carbon Fiber for Deepwater Umbilicals

October 15, 2010

carbonfiberfordeepwaterumbilicals
The umbilicals in the oil and gas industry are the lifelines of deepwater O&G fields, connecting wells to the offshore platform. The use of carbon fiber rods to replace some of the steel sheathing is an interesting development for use in deepwater umbilicals.Since the 1990s, subsea production systems have become increasingly important, specifically for deepwater plays. Some wells or well systems are located as far as 100 km from the production rig and may be up to 3,000 meters deep. As a result, umbilicals composed of steel tube conduit, thermoplastic hose, or a combination of the both, are critical for power, control, communication, and fluid injection to keep deepwater wells working efficiently and producing continuously.
