Leading Reservoir Services Company Geotrace Strengthens Its Suite of Deghosting Techniques

Geotrace Technologies Inc. (www.geotrace.com), an industry leader in high resolution exploration and production (E&P) solutions, today announced the success of HDBand, one of the most versatile and flexible suites of deghosting techniques in the industry. Geotrace’s proprietary HDBand technology suite focuses on the recovery of low and high frequencies to produce cleaner, sharper and higher resolution seismic data, especially in marine reservoir applications.

“With HDBand, Geotrace’s customers will have unmatched access to the latest industry technologies that attack ghosts in marine imaging,” said Bill Schrom, Geotrace CEO. “Eradicating these water surface frequency disruptions increases the resolution of a client’s imaging capabilities, giving them the highest quality data and leading to better informed decisions.”

Ghosting occurs when reflections from the water’s surface create notches in seismic imaging, and result in a resolution loss. Deghosting technologies thus help eliminate resolution damage and improve clarity in seismic data.

Geotrace’s marine deghosting techniques are purposely designed to be flexible and applicable at three key stages of a processing sequence: pre-imaging, post-imaging and post-stack for various streamer configurations at constant, slant or variable depths. A pre-imaging application can significantly improve the resolution for better velocity analysis and a more detailed final image, while a post-imaging application can be an efficient and cost effective solution, useful for AVO/AVA and inversion applications. The technology is also applicable before or after migration and can be used in post-stack mode. For reservoir characterization, a post-stack application can be the most cost effective - and often times the only - solution, particularly when pre-stack data is not available.

HDBand is designed to work with other techniques such as Q compensation and spectral whitening. Both can be applied to compensate seismic attenuation and improve the seismic resolution for structural and stratigraphic interpretation, inversion and reservoir characterization.

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happe...
The Internet of Things will put IT to its ultimate test by creating infinite new opportunities to digitize products and services, generate and analyze new data to improve customer satisfaction, and discover new ways to gain a competitive advantage across nearly every industry. In order to help corporate business units to capitalize on the rapidly evolving IoT opportunities, IT must stand up to a new set of challenges.

The Internet of Things promises to transform businesses (and lives), but navigating the business and technical path to success can be difficult to understand. In his session at @ThingsExpo, Sean Lorenz, Technical Product Manager for Xively at LogMeIn, demonstrated how to approach creating broadly successful connected customer solutions using real world business transformation studies including New England BioLabs and more.
An entirely new security model is needed for the Internet of Things, or is it? Can we save some old and tested controls for this new and different environment? In his session at @ThingsExpo, New York's at the Javits Center, Davi Ottenheimer, EMC Senior Director of Trust, reviewed hands-on lessons with IoT devices and reveal a new risk balance you might not expect. Davi Ottenheimer, EMC Senior Director of Trust, has more than nineteen years' experience managing global security operations and asse...
DevOps is all about agility. However, you don't want to be on a high-speed bus to nowhere. The right DevOps approach controls velocity with a tight feedback loop that not only consists of operational data but also incorporates business context. With a business context in the decision making, the right business priorities are incorporated, which results in a higher value creation. In his session at DevOps Summit, Todd Rader, Solutions Architect at AppDynamics, discussed key monitoring techniques...
P2P RTC will impact the landscape of communications, shifting from traditional telephony style communications models to OTT (Over-The-Top) cloud assisted & PaaS (Platform as a Service) communication services. The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at @ThingsExpo, Robin Raymond, Chief Architect...
What do a firewall and a fortress have in common? They are no longer strong enough to protect the valuables housed inside. Like the walls of an old fortress, the cracks in the firewall are allowing the bad guys to slip in - unannounced and unnoticed. By the time these thieves get in, the damage is already done and the network is already compromised. Intellectual property is easily slipped out the back door leaving no trace of forced entry. If we want to reign in on these cybercriminals, it's hig...
The definition of IoT is not new, in fact it’s been around for over a decade. What has changed is the public's awareness that the technology we use on a daily basis has caught up on the vision of an always on, always connected world. If you look into the details of what comprises the IoT, you’ll see that it includes everything from cloud computing, Big Data analytics, “Things,” Web communication, applications, network, storage, etc. It is essentially including everything connected online from ha...

We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management.
