Today let’s look at VSP and how it can be used for your CCS project. In VSP (Vertical Seismic Profile), receivers are placed down a borehole with the source points located on the earth’s surface which results in a high resolution image of the subsurface near the borehole location. VSP provides the greatest value to a CCS project IN THE EARLY STAGES OF CO2 PLUME MONITORING. In the early months of injection, the CO2 plume is small and can be easily imaged by a VSP survey. BUT… VSP has a LIMITED APERTURE. The distance from the borehole that can be imaged is very limited. As the CO2 plume grows, there will be a point where the plume will grow outside the imaging limits of the VSP. If you have any questions feel free to contact us at: https://lnkd.in/e4W_9bRt Watch out for tomorrow’s video as we continue the discussion on TYPES OF SEISMIC.

Good Morning LinkedIn ⛅️ It’s a new week and a new episode on my knowledge sharing series “LearnWithSpiphy📚” Today’s Focus: Seismic Acquisition 📖 Seismic Acquisition is the process of using seismic waves to acquire data of the earth subsurface. It involves the use of two major instruments, which are the seismic sources and the seismic sensors(receivers).📖📚 Attached is a set of slides displaying a proper understanding of seismic acquisition as well as seismic sources. Take a look, share your thoughts, and let’s engage! 💡🥂 #LearnWithSpiphy #Petroleumgeology #SeismicAquisition #NYSC #LASG #Degeconek #Lagoskopa

New discoveries are being drilled from Static MT geophysical data, specifically deploying the Omega MT Ultra Wideband technology. Static Magnetotellurics, aka ground MT with a Full Tensor configuration, offers enhanced imagery with the added dimension of significantly deeper depth of investigation. Investigations can reach 100 km or more; however, for realistic economic exploration and exploitation, depths of up to 3 km are of most interest. With ground MT imaging, contact and sensor orientation is ideal and sensors can be set up precisely and with stability for measurement. It's an advanced targeting regime as compared with moving methods. When targeting and accuracy of targets for drilling are key, ground geophysics performs. In the image below, we see one of Simcoe's field crews setting up a precision Omega MT station with Full Tensor configuration, the resulting Resistivity values are precise with optimal definition of targets from near surface to deeper depths with wideband coverage across almost the complete depth (i.e. Ultra Wideband frequency) spectrum. To leverage MT in your exploration project, visit SimcoeGeoscience.com or speak with our Principal and Team Leaders at the PDAC conference in Toronto starting Sunday March 3. We are in booth 616 for the conference and would be delighted to chat with you about your MT and other ground geophysical targeting. #GroundMT #OmegaMTUltraWideband #ResistivityImaging #DeepExploration #CuPorphyry #Geothermal #LiBrines #NextGenerationGeophysics

Today, Jacques Deparis from BRGM is presenting new results On the use of time Series to improve Signal processing of Electrical Data. 😎 This works has been done together with Julien Gance and ORLANDO LEITE from IRIS Instruments 💫This collaborative work focuses on new apparatus and data processing in time and spectral domain. A big step for users in environment and ground water topics. We encourage you to stop by our poster at the #NSGE Asia Pacific EAGE (European Association of Geoscientists and Engineers) in Tsukuba (Japan). #nearsurface #geophysics

𝐍𝐞𝐰 𝐂𝐨𝐧𝐭𝐫𝐢𝐛𝐮𝐭𝐢𝐨𝐧 𝐟𝐫𝐨𝐦 𝐭𝐡𝐞 #UNITUS 𝐍𝐮𝐜𝐥𝐞𝐚𝐫 𝐅𝐮𝐬𝐢𝐨𝐧 𝐑𝐞𝐬𝐞𝐚𝐫𝐜𝐡 𝐓𝐞𝐚𝐦 📄 A new scientific paper titled "Effects of Seismic Isolation on the Dynamic Behaviour of the DTT Torus Complex During Earthquake Events" has been published in Fusion Engineering and Design journal. 🌍 It details the latest advancements in the construction of the Divertor Tokamak Test (#DTT) fusion machine at the ENEA site in Frascati, Italy. The location has been identified as being at high seismic risk. Preliminary analyses of seismic effects from local response spectra have been carried out on the structure, namely the cryostat base, supporting the vacuum vessel, the magnets and the cryostat, using both static equivalent and dynamic methods, and a reference design has been obtained. 🛠️ An update of the geological seismic surveys for the site showed a more severe local seismic response than previously considered. The analyses based on the updated seismic response revealed potential structural criticality for the base. Therefore, two possible seismic isolation solutions were considered to reduce the stress state. Finally, a comparison in terms of displacement and stress fields between the non-isolated configuration and the two isolated ones is presented. 📊 Access the full paper to find out more: https://lnkd.in/gU-h72_N #NuclearFusion #SpectrumAnalysis #Earthquake #SeismicIsolation Marco Fulici Valerio Belardi Mauro Dalla Palma Pierluigi Fanelli

🌍 How does spatial area influence seismic site response? Find out at Prof. Brady R. Cox's seminar on May 17th at 3:00 PM at the EUCENTRE Foundation in Pavia. During the event, Prof. Cox will present a new geostatistical approach based on horizontal-to-vertical spectral ratio (HVSR or H/V) measurements that can be used for building large and deep pseudo-3D shear wave velocity (Vs) models as a means to rationally account for spatial variability in seismic ground response analyses (GRAs). The efficacy of various strategies used to account for spatial variability in 1D, 2D, and 3D GRAs will be discussed in the context of several case histories based on recorded ground motions at borehole array sites. Don't miss this unique opportunity to learn from an internationally renowned expert in seismic design and in-situ site characterisation. #spatialarea #seismicresponse
