The Process Behind GTL Conversion

June 19, 2013

cgtl smalll
Liquid hydrocarbon fuels can be produced from associated natural gas via a well-known catalytic chemical reaction called Fischer-Tropsch (FT) synthesis. The FT synthesis is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen into liquid hydrocarbons. It was first developed by Franz Fischer and Hans Tropsch at the "Kaiser-Wilhelm-Institut für Kohleforschung" in Mülhei an der Ruhr (Germany) in the 1920s. During World War II, FT synthesis provided the needed liquid hydrocarbon fuels for the German war effort. Later, facing isolation during the apartheid era, South Africa turned to FT synthesis from coal gasification to supply significant quantities of its hydrocarbon fuel needs.

Brazil´s Floating Offshore Oil Terminal set for 2014

June 18, 2013

Petrobras will launch a world first floating offshore oil terminal in order to be able to transfer oil to oil tankers offshore, beginning in 2014. Up until now the oil had to be transported through pipelines from the offshore rigs to the coast where tankers would load up the oil. It is expected that this new system will decrease oil transportation costs as tankers will be relieved from the high Brazilian port taxes, the tankers will also save up on their own bunker oil as the distances they will have to travel will decrease. The new system should be used mainly for export oil and will also probably be a hub for tankers coming to fill up on deepwater pre-salt oil.

PipeWay Tools –Pigging Equipment Made in Brazil

PipeWay is also a spinoff from the Genesis Institute run by PUC University in Rio de Janeiro. PipeWay Engeneering is the only company in the Southern Hemisphere with fully national production, which manufactures and operates tools for O&G pipeline inspection, which check anomalies such as oval pipes, crushing and corrosions, contributing to avoid leakages that may cause environmental accidents and safety hazards. PipeWay entered the O&G market in 1998, when the group of researchers from the Pontifical Catholic University of Rio de Janeiro (PUC-Rio), by using the technology of Petrobras' Research and Development Center (CENPES), launched a tool for pipe integrity management.

The SUT Technical Conference 2010 will be held in Rio de Janeiro and promises to be the main subsea event of the year in Brazil.The Society for Underwater Technology (SUT) is a multi-disciplinary learned society that brings together organisations and individuals with a common interest in underwater technology, ocean science and offshore engineering. SUT was founded in 1966 and has members from more than 40 countries, including engineers, scientists, other professionals and students working in these areas. Cross-fertilisation and dissemination of ideas, experience and information between workers in academic research, applied research and technology, industry and government. Development of techniques and tools to explore, study and exploit the oceans.

Aubin Brings its Gel Based Products to Brazil

June 15, 2013

devonlarge
Although the Scottish chemical technology company Aubin originally specialized as a cement and stimulation additive supplier, it has made strong inroads into the Oil and Gas industry in recent years, with the subsea sector being their main target. The company is based in Ellon, Aberdeenshire and has been in business since 1987. Some 6 years ago they came up with a novel product, which came to be known as “gel with a memory”. It is mainly used for pipe pigging purposes as it can be squashed but returns to its original shape. Named L-gel, the product is also used for risers, which are considered impossible to be pigged. It can go around tight bends and through blocked areas where a conventional pig would probably get stuck.

C&C Technologies Thriving in the Brazilian AUV Market

June 16, 2013

Hugin
C&C entered the Brazilian market with its autonomous underwater vehicles (AUV) almost ten years ago. The company has had a steady growth in the country and now provides services that involve measurement of water properties, seabed topography, and seabed soil characterization. C&C uses their own vessels as platforms to launch their AUVs, covering the depth range from ultra shallow all the way to ultra deep 4500 meters and their clients use the data acquired by their AUVs to support their underwater infrastructure construction plans. In Brazil the company has enlarged its scope of services on demand by clients after the success of their seafloor mapping technology using side scan sonars mounted on AUVs C&C is also undertaking extensive work in oceanography and environmental monitoring.

Major New O&G Pipelines Raising Environmental Concerns

June 16, 2013

Recently Petrobras, the Brazilian national O&G operator announced that it had awarded Technip a 5-year frame agreement contract for the supply of around 1,400 kilometers of flexible pipes, with supply starting in 2013 and orders are guaranteed for at least 50% of the total value, which is currently estimated to be worth around US$2.1 billion. Flexible pipes for the contract will be produced both at Technip's existing manufacturing site in Vitoria, and also at our new manufacturing facility under construction in Açu, Brazil. This agreement is a direct spinoff of the investment Technip made last year in building a second state-of-the-art flexible pipe plant in Brazil…

Petrobras set to announce winner of offshore LNG production unit tender

June 16, 2013

The group that will be awarded the construction contract for this novel offshore LNG production unit will be known by October 31 Petrobras is keen to begin construction of the unit as it considers offshore natural gas liquefaction vital to guarantee a efficient output for the Santos Basin pre-salt gas. Many of the Santos Basin pre-salt fields are located over 300km from the coast, which convinced Petrobras to seek other options in order to deliver the gas to the market. Normally gas is transferred from wells to the coast through underwater pipelines but with such distances involved and with many of thereservoirs located in deep water…

Major Deepwater Contract with Petrobras Spotlights Subsea 7´s Enhanced Capabilities

The $1 billion contract awarded to Subsea 7 by Brazilian national oil company Petrobras, marks a new era in Subsea 7´s history. It is the first major (in terms of contract value) contract for the company after its merger with Acergy. The contract is for development of the Guara and Lula deepwater pre-salt fields in the Santos Basin, over 300km from the coast of Rio de Janeiro, in water depth of around 2,200 meters. These plays are located in Block BM-S-9 and BM-S-11 respectively. The EPIC (Engineering, Procurement, Installation and Pre-Commisioning) project scope consists of 4 decoupled riser systems featuring, four submerged buoys each of 1…

Investing in subsea pipeline technology development, PROTUBO has been producing interesting pipe bending solutions.Pipes are one of the most costly equipments in subsea systems. Here in Brazil subsea pipelines can range from tens, to hundreds of kilometers. Usually subsea pipelines include bended sections and more recently ( T ) pieces are installed in them to facilitate intervention, specially in deep water sections, where intervention costs are huge and new rigless intervention techniques are being introduced. In deep water pipelines, pipe in pipe technology is being extensively used and upgraded in order to optimize surveillance capabilities, where real time fiber optic surveillance technology appears to be the way to go.
