Aker on Managed Pressure Operations
When Aker Solutions acquired Managed Pressure Operations in 2013, it became a provider of next generation continuous circulation and managed pressure drilling (MPD) systems, which has become a critical component to the drilling process going into the future. MPD systems have proven to be reliable, enabling maximum up time and significant cost savings and has been labeled of strategic importance for pre-salt drilling by Brazilian operator Petrobras, which uses MPD systems developed by Weatherford, which was the company that first introduced large scale use of the system to the industry. The MPD system being introduced by Aker/MPO is fully automated and simple to operate, needing few people to run the equipment.
Future Trends – Automated Drilling
Some interesting trends are developing within the O & G industry, one of which is the trend towards increasingly automated drilling. Since the early stages of onshore and offshore drilling, the act of drilling itself has been undertaken as a hands-on job by specialized workers, along the last decade this has begun to change with the introduction of autonomous computer-controlled drilling operations, also known as drilling automation. Oil and Gas operators are developing technologies which they hope will allow drilling operations to be automated, consequently meeting their safety goal of zero people hurt on the job and also reducing drilling operation costs.
Advanced Drilling Technology: Mapping-While-Drilling
Oil and Gas drilling teams usually contend with tight schedules for project developments and this may eventually lead to low quality plans and limited risk assessment, which may cause expensive and potentially dangerous drilling problems, such as, stuck pipes, violent kicks, unproductive time and cost overruns. The introduction of Schlumberger’s reservoir mapping-while-drilling service is enabling drillers to make better decisions in short timeframes and avoid costly mistakes. For the operators, the main benefits from the effective well placement may be maximized production, minimized construction and intervention costs. The process of well placements brings together many different disciplines…
Naturally-Occurring Radioactive Materials in the O&G industry
Nuvia is one of the leading provider of Naturally Occurring Radioactive Material (NORM) management services in the UK. According to the U.S. Geologists have recognized their presence since the early 1930s and use their presence as a method for finding petroleum systems. Much of the petroleum in the earth's crust was created at the site of ancients seas by the decay of sea life. As a result, petroleum deposits often occur in aquifers containing brine (salt water). Radionuclides, along with other minerals that are dissolved in the brine, precipitate (separate and settle) out forming various wastes at the surface, such as mineneral scales inside drilling and production pipe, sludges, contaminated equipment or components and produced waters.
Research Drilling Proposals for the Brazilian Equatorial Margin
A NSF-sponsored workshop will be held in the coastal town of Maresias, São Paulo, Brazil, from the 4th to the 6th of February 2014, to discuss, plan and define the conceptual basis for developing an International Ocean Discovery Program (IODP) Drilling Proposal to investigate the Brazilian Equatorial Margin. b) The opening and expansion of the South Atlantic Ocean. The Brazilian Equatorial Margin (BEM) is a passive, stable margin at equatorial latitudes characterized by continuous sedimentary sequences divided among a series of basins. These basins contain a unique record of regional tectonic, biotic, and climatic events from the end of the early Cretaceous to present.
Efficient Drill Bits for the Pre-salt
The expression "pre-salt" refers to an aggregation of rocks located offshore along large portions of the Brazilian and West African coasts, it forms a carbonate rock interval that ranges under an extensive layer of salt which, in certain areas of the Brazilian coast, can be as much as 2,000 meters thick. The total depth of these rocks formations, or the distance between the surface of the sea and the oil reservoirs under the salt layer, can be as much as 7,000 meters. Drilling in the pre-salt is extremely complex and may require multiple trips being made by the drill bit in order to drill short lengths due to different rock layers with varying degrees of hardness. Another challenge is that the salt is very corrosive and is also plastic, as you drill down, it tends to close the well walls.
Environmental Risks of Drilling the Brazilian Equatorial Margin
With the 11th round of tendering for O&G block in Brazil set to start next week, it is important to look at some of the serious risks involved in drilling for O&G in Brazil’s Equatorial Margin. Most of the offshore blocks being tendered in this 11th round of bidding are located along Brazil’s northeast and north coasts. This, according to the Brazilian government, is being done in order to de-centralize O&G production in Brazil, where most of the oil and gas E&P is done along the southeast coast, basically centered off the states of São Paulo, Rio de Janeiro and Espirito Santo. This is all well and good, when considering the need to redistribute O&G wealth to other parts of the country…
JIP Collapse Assessment of Offshore Pipelines with D/t < 15
Based on project experience, research, and joint industry development work, DNV issues a number of pipeline codes. These comprise service specifications, standards and recommended practices, and are highly regarded within the international pipeline community. The DNV OS-F101 ‘Offshore Standard for Submarine Pipeline Systems’ provides acceptance criteria and design procedures for pipelines. The standard applies modern limit-state-design principles with ‘safety classes’ linked to consequences of failure. The DNV standard is complemented by several recommended practices (RPs), which give detailed advice on how to analyze specific technical aspects according to stated criteria.
Brasil Supply offering Integrated Solutions for the O&G Industry in Brazil

Further south, they also operate in the city of Itajaí, in the State of Santa Catarina, and are developing a significant operation in the Northeast of the country, in association with other major service providers.
The Cost of Deepwater E&P
This cost isn´t only in equipment and manpower, it´s in lives, human and animal and destroyed ecosystems which will take at least a decade to recuperate. Safety must always come first. Even with the most reliable equipment and redundancy, there will always be the human factor. Nothing like a full on environmental tragedy to make for a vital attitude change: Safety first, and then all the profit scene. We all know now, that there is no infallible safety measure, well not man proof anyway. Pressure seems to be a wee bit of a problem too. Like the old saying goes: You only knows, when it blows! Well now we know, don´t we? This is the worst case scenario and it could not be correctly simulated.
Pre-salt - Technological Challenges
Although not considered a major challenge by Petrobras, drilling two thousand meters below the water line, through about three thousand meters of sediments, and through two thousand meters of salt is done at the frontiers of technology.Drilling at a depth of two thousand meters is not a problem. Petrobras already has several wells at this depth, in Brazil and in the Gulf of Mexico, and produces at 1,886 meters in the Campos Basin, a mark that was once the world record (Shell currently holds the record, at more than two thousand meters from the water line in the Gulf of Mexico). The biggest challenge is the layer of salt, which, under high pressure and at high temperatures…

The OGX Exploratory Campaign Maintains Its High Success Rate
OGX Petróleo e Gás Participações S.A., the largest Brazilian private sector oil and gas company in terms of offshore exploratory acreage, announced today that it has completed the drilling of well 1-OGX-5-RJS, located in block BM-C-43, in the shallow waters of the southern part of the Campos Basin. OGX holds a 100% working interest in this block. The well OGX-5 was drilled to a depth of 4,100 meters, resulting in the detection of hydrocarbons in carbonate reservoirs in the Albian and Aptian sections. Cable tests performed after the conclusion of drilling also identified an oil-bearing column in the Maastrichtian section, from which oil samples were collected.
