Quantitative and qualitative seismic attributes interpretationmohamed Shihata
Seismic attribute is the only way that can enable interpreter to understand seismic data very well and generate new view for his model, but there are hundreds of seismic attributes and there are many classes that make interpreters afraid of using new thing so in this course explain both theoretical and application for each one and try to generate workflow to help interpretation for different geological environment.
In this course, we will gain an intuitive understanding of the kinds of seismic features that can be identified by 3-D seismic attributes, the sensitivity of seismic attributes to seismic acquisition and processing, and of how ‘independent’ seismic attributes can are coupled through geology. We will also discuss alternative workflows using seismic attributes for reservoir characterization as implemented by modern commercial software and practiced by interpretation service companies. Participants are invited to bring case studies from their workplace that demonstrates either the success or failure ofseismic attributes to stimulate class discussion.
Here are the lab assignments of Geophysical Exploration. It includes introduction of different geophysical equipments, seismic survey, GPR, magnetic survey, Gravity survey and resistivity survey. All applications of survey is listed in the document.

Developments and directions in 3D mapping of mineral systems using geophysicsRichard Lane
(See Geoscience Australia website - https://www.ga.gov.au/products/servlet/controller?event=GEOCAT_DETAILS&catno=70386 ). “Developments and directions in 3D mapping of mineral systems using geophysics” by Richard Lane (Geoscience Australia, richard.lane@ga.gov.au). Presented at “Science at the Surveys” (Melbourne, Victoria, Australia, 22 March 2010). The primary author would like to acknowledge the assistance of many people who have provided material and thoughts for this presentation, with special mention of Richard Chopping, Marina Costelloe, David Hutchinson, Nick Williams, and Lesley Wyborn.

Microseismic monitoring at the CCS fields - what we learnt from NagaokaGlobal CCS Institute
Dr Ziqiu Xue, Chief Researcher of the CO2 Storage Group at Japan’s Research Institute of Innovative Technology for the Earth (RITE) will lead a Global CCS Institute webinar to review and discuss microseismic monitoring at CCS storage sites.
The secure storage of carbon dioxide (CO2) in deep geological formations requires a sufficient overlying cap rock layer to contain the CO2 within the formation. Injection of CO2 increases the formation pressure in the target reservoir. This will decrease the effective pressure and will also lead to geomechanical deformation of the rocks. Therefore, to ensure safety of storage, the CO2 injection must be controlled to maintain integrity of the cap rock.
This webinar will give a simple review on microseismic monitoring results observed at onshore CO2 injection sites such as Weyburn, Canada and Lacq, France. Case study results from the Nagaoka pilot site in Japan will also be introduced, including the field survey results after an earthquake hit the area during CO2 injection.
This is the presentation for a webinar that we recently held, explaining the use of energy-dispersive spectrometry (EDS) on the scanning electron microscope (SEM) and micro-X-ray fluorexcence spectrometry (µ-XRF) in geosciences. You will find lots of interesting applications from this field.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms.

• The 3 component data was recorded using 1 profile, hence we
got 96 traces in each record.
• Before any processing could take place we had to separate the
H-1 and H-2 components.
• Using VISUAL SUNT we successfully separated the
components and got only the V-3 component.
