Well control equipment: Metal hat, Fireproof coveralls… CFD
By Gaetan Bouzard – In the Oil & Gas industry, the integration of possible risk linked with well control — such as subsea plume, atmospheric dispersion, fire and explosion — is critical for minimizing impact on the entire system or on operations efficiency, and for ensuring worker health and safety. Risk to system integrity must be prevented at the design phase, but also addressed in case hazards happen along equipment lifetime or system in operation.
Last September 25th, Mr. Alistair E. Gill, from company Wild Well Control demonstrates the value of advanced structural and fluid dynamics mechanics simulation for well controls, emergency response and planning, as part of a Live Webinar organized by Siemens and Society of Petroleum Engineers. In this article I will try to summarize his presentation. To have more insights feel free to watch our On-Demand Webinar.
To be honest when talking about well control for Oil & Gas industry, people usual conception is that some disaster happened and guys wearing protections are trying to light off a big fire. Actually companies such as Wild Well Control are using modern and innovative techniques as Computational Fluid Dynamics (CFD) simulation to support practical team on a well control incident trying to keep asset integrity at the same time.
Mr. Gill provides several examples to demonstrate simulation techniques that were used from
- Subsea plume and gas dispersion modeling to understand where hydrocarbons go in the event of a blow out
- Radiant heat modeling in case of a fire
- Erosion modeling
- Thermal as well as Structural analysis
There is basically three major categories of simulation used, starting with everything related to the flow within the well bore, looking at kick tolerance, dynamic kill or bull heading; next anything to do with 3D flow using CFD simulation which is the main focus of this article; finally structural analysis using Finite Element modeling. more>

Democratic voters actually care about climate change. 2020 candidates are responding.
By Ella Nilsen – Rep. Alexandria Ocasio-Cortez thinks former Vice President Joe Biden’s $5 trillion climate plan — one of the first major policies his campaign has released — is a “start,” albeit one that needs to be scaled up dramatically.
“I think what that has shown is a dramatic shift in the right direction, but we need to keep pushing for a plan that is at the scale of the problem,” Ocasio-Cortez, progressive superstar and co-sponsor of the Green New Deal, told reporters on Tuesday. (For the record, she thinks the plan that gets closest is Washington Gov. Jay Inslee’s, which she called the “gold standard.”)
But the very fact that Biden felt the need to release a climate plan near the start of his policy rollout shows the influence and success of Ocasio-Cortez and her allies in the climate movement.
Five candidates, including Biden, Inslee, Sen. Elizabeth Warren, and former Reps. Beto O’Rourke and John Delaney have all released massive plans to combat climate change, ranging from $1.5 trillion to $3 trillion in federal investment over a decade. Candidates are factoring in the spur of private investments as well, hence the jump to $5 trillion in Biden’s plan.
“It’s a recognition of where the electorate is,” Monmouth University polling director Patrick Murray told Vox. “This popped out from the very beginning. Climate change and the environment in general was the No. 2 issue after health care for Democratic voters.
“I think it’s just becoming a zeitgeist for Democrats,” Murray added.
Over the past eight months, climate change has shot up as a core Democratic issue in polls. more>

By Umair Irfan – Humans are pumping more carbon dioxide into the atmosphere at an accelerating rate. But climate change is a cumulative problem, a function of the total amount of greenhouse gases that have accumulated in the sky. Some of the heat-trapping gases in the air right now date back to the Industrial Revolution. And since that time, some countries have pumped out vastly more carbon dioxide than others.
The wonderful folks at Carbon Brief have put together a great visual of how different countries have contributed to climate change since 1750. The animation shows the cumulative carbon dioxide emissions of the top emitters and how they’ve changed over time.
What’s abundantly clear is that the United States of America is the all-time biggest, baddest greenhouse gas emitter on the planet.
That’s true, despite recent gains in energy efficiency and cuts in emissions. These relatively small steps now cannot offset more than a century of reckless emissions that have built up in the atmosphere. Much more drastic steps are now needed to slow climate change. And as the top cumulative emitter, the US bears a greater imperative for curbing its carbon dioxide output and a greater moral responsibility for the impacts of global warming.
Yet the United States is now the only country aiming to withdraw from the Paris climate agreement. more>

New technology in industry is creating a platform economy
By Frank_Fang – Twenty years ago, product-centric companies dominated a list of the most valuable companies in the world. The list was a Who’s Who of automotive, manufacturing, oil and gas, and brick-and-mortar retailers.
Today, platform-based businesses rule.
This new economy forces product-centric manufacturing companies to rethink how they transform digitally to survive and thrive in a data-rich market. It’s no secret that new technology and new approaches eventually supersede the old.
We’re witnessing one of these periods now. As manufacturers look for ways to radically redefine processes through the hype of the sharing economy, online platforms, the end of money and all the other buzzwords people use today, digital twin evolution will lead to platform economy, a state Viktor Mayer-Schönberger foresees in his book Reinventing Capitalism in the Age of Big Data.
Digital twins, which evolve from decades of simulation and analysis in engineering, are high fidelity models for actual physical objects such as a product or production process. Using computer aided-design, model-based system engineering and multiphysics simulation tools, a designer or engineer creates a digital representation for a physical object or process.
The digital twin is no longer science fiction. For example, NASA used this approach to design, engineer and produce two Mars rovers: Curiosity and InSight.
Since you can’t build a Mars environment on earth, you simply bring Mars to the computer and digitally test your Mars rover. more>

Earth observation for weather prediction – solving the interference problem
By ITU News – “Today, several dozen satellites contribute to the accumulation of critical knowledge about the Earth’s system, enabling scientists to describe specific links between a major natural disturbance in the upper atmosphere, and changes in the weather thousands of miles away,” says Mario Maniewicz, Director of the ITU Radiocommunication Bureau.
“As accurate weather predictions need to start from the best possible estimate of the current state of the atmosphere, it is crucial that meteorologists have real-time, accurate global observations about what is happening in the Earth’s atmosphere over land and oceans. And for this, they rely on space sensing.”
Space sensing relies on the deployment of sensors to obtain data critical for Earth observation from space. Active sensors are radar systems on spaceborne platforms. They obtain data through the transmission and reception of radiowaves. Passive sensors, meanwhile, are very sensitive receivers that measure the electromagnetic energy emitted and scattered by the Earth, and the chemical constituents in the Earth’s atmosphere. They require protection from radio-frequency interference.
Spaceborne sensors measure the background natural radiative emission floor, therefore any man-made signal (e.g. communications, radars) that rises above this natural emission floor will likely interfere with the measurements. This interference can be tolerated only if its energy is well below the sensor sensitivity. more>

Multi-Discipline Data Management for Electronics
Siemens – Integrated hardware and software design and testing on electronic products are now part of a system of delivery needs, which can only be enforced by a tightly integrated and unified multi-discipline platform.
Manage multi-disciplinary engineering teams with an integrated approach to engineering lifecycle management that leverages integrated requirements management, secure supplier collaboration and an engineering management platform that combines mechanical, electronic and software co-design and co-simulation in a single collaborative environment.
Today’s electronic devices are a synthesis of multiple designs—mechanical, electrical, electronics, embedded software and application software. In addition, because of rapid development, many hardware features remain unexplored and under-managed resulting in sub-optimal integration between hardware and software.
The disadvantages of operating in different single-discipline platforms and the increasing role of global suppliers in early stages of design are driving engineering organizations to invest in multi-domain integration strategies to ensure the system works flawlessly. more>
