The motivation for high-performance computing in reservoir simulation has always existed. From the earliest simulation models, computing resources have been severely taxed simply because the level of complexity desired by the engineer almost always exceeded the speed and memory of the hardware. The high-speed vector processors such as the Cray of the late 1970s and early 1980s led to orders-of-magnitude improvement in speed of computation and led to production models of several hundred thousand cells. The relief brought by these models, unfortunately, was short-lived. The desire for increased physics of compositional modeling and the introduction of geostatistically/structurally based geological models led to increases in computational complexity even beyond the large-scale models of the vector processors.
Cyber security affects every aspect of modern life, from personal emails to identity information, corporate payrolls, or even national intelligence secrets. Within the oil and gas industry, cybercrime such as data breaches can cause major threats to organizations. Supervisory Control and Data Acquisitions (SCADA) and Drilling Control Systems (DCS) are two control systems that are critical to the infrastructure of the oil and gas industry. Originally designed to be in physically secured, isolated areas, these systems must now be integrated with IT networks. This integration, along with the increased use of commercial off the shelf components (COTS), like USB drives and Windows, has decreased the isolation of SCADA and DCS, thus increasing vulnerability to attacks.
An 18-month project will develop and trial a mobile robot for autonomous operational inspection of Total facilities. A consortium of organizations has set out to tackle one of the more enduring challenges in the North Sea: the nondestructive testing (NDT) of corroded pipes under insulation and engineered temporary pipe wraps. General Electric has launched a subsidiary to develop and sell the use of flying, crawling, and swimming drones for inspections in the oil and gas industry, among others, the company announced. Behind the use of most drones and unmanned aerial vehicles is the issue of safely and legally operating beyond the visual line of sight (BVLOS).
The US Occupational Safety and Health Administration, the National Institute for Occupational Safety and Health, the State of North Dakota, and the Bakken Basin Safety Consortium have signed an alliance to protect employees and promote safety and health in the oil and gas industry. The National Institute for Occupational Safety and Health is collaborating with partners in industry, government, academia, and labor and with other stakeholders to achieve successful and sustainable outcomes to improve worker safety and health across the oil and gas extraction industry. The tool, called the Field Analysis of Silica Tool, works with commercially available Fourier-transform infrared analyzers to determine a worker’s exposure to respirable crystalline silica dust, providing detailed results immediately following a worker’s shift. Millions of workers are exposed to noise in the workplace every day and, when uncontrolled, noise exposure may cause permanent hearing loss. Research demonstrates exposure to certain chemicals, called ototoxicants, may cause hearing loss or balance problems, regardless of noise exposure.
Optimizing the design, function, and benefits of the logical cyber-representation of physical asset environments is an evolving trend for the oil and gas industry to gain operational efficiency. Cyberattacks are an increasing threat globally to businesses and organizations, very much including the oil and gas industry, with operating activity of all kinds exposed as well as information technology networks. A computer scientist with the US Federal Bureau of Investigation says that oil and gas companies must do more to protect themselves from cyberattacks. A new survey shows oil and gas CEOs are most worried about cybersecurity and the speed of technological change. Cyber threats have expanded beyond data breaches and the theft of intellectual property.
The goal is to support the development and sharing of best-practice approaches for project delivery and asset operations using cloud services and digital workflows in engineering and operations. Whether using internal expertise or outside consultants, projects and initiatives can go awry due to cultural issues and bad management advice. This can have implications for many aspects of a business, including process safety.
Operators are increasingly using existing offshore infrastructure for asset life extension, and developing new marginal stranded fields rather than develop new large greenfields. Subsea processing is an enabling technology in this goal. A cybersecurity director outlines the steps needed to adopt a risk-based cybersecurity program. He cautions that in many cases, process control systems’ confidentiality is mistakenly viewed as a lower priority than IT systems’. AUVs aren’t limited to inspections and pipeline surveys.
