Which industries rely on geophysical surveys for subsurface analysis? Geophysical surveys are used in several industries to conduct subsurface analysis. Some of the industries that rely on geophysical surveys for subsurface analysis include: 1. Mining industry: Geophysical surveys are used to locate mineral deposits beneath the earth's surface, to estimate the quantity and quality of mineral resources and to plan mining operations. 2. Petroleum industry: Geophysical surveys are used to locate oil and gas reserves, to estimate the size and shape of reservoirs, and to monitor oil and gas extraction. 3. Environmental industry: Geophysical surveys are used to identify and evaluate environmental hazards such as soil contamination, landfill sites, and groundwater pollution. 4. Construction industry: Geophysical surveys are used to identify potential subsurface hazards, such as sinkholes, voids, and underground utilities, before construction can begin on-site. 5. Civil engineering industry: Geophysical surveys are used in the design of infrastructure projects such as roads, bridges, tunnels, and dams to evaluate the geological and hydrological conditions of the subsurface. In conclusion, geophysical surveys are used extensively in various industries for subsurface analysis. These surveys provide valuable insights into subsurface conditions, which can be crucial for planning and decision-making in different industries. #survey #offshorejobs #offshore #rov #offshorewind Visit our website for more information. www.quasarsubsea.com

I just want to share the insights I gained for today about site investigations in pre-development planning. It turns out that combining geophysical methods such as seismic refraction, ground-penetrating radar, and electrical resistivity with civil engineering techniques such as borehole drilling, standard penetration tests, and cone penetration tests provides a comprehensive understanding of the subsurface. Geophysical methods are non-invasive, fast, and cost-effective for large areas, offering a broad view of subsurface conditions such as bedrock depth, faults, and groundwater. However, these methods can sometimes struggle with data interpretation and resolution in shallow layers. This is where civil engineering methods excel. They give us direct, detailed data on soil properties like strength and load-bearing capacity but tend to be more localized, time-consuming, and expensive. What I’ve learned is that integrating both approaches is key. Geophysical methods help identify areas of interest quickly, while civil engineering tests provide the precise data needed for safe construction. This balanced approach minimizes risks, optimizes resources, and ensures a more accurate understanding of the site before development begins. Answering questions about the benefits and limitations of these methods really showed me the importance of using the right tools to achieve both efficiency and accuracy in site investigations. It’s all about making smarter decisions for safer construction projects! #Geophysics #CivilEngineering #SiteInvestigation #ProjectPlanning #ConstructionSafety #ContinuousLearning

Subsea pipeline / flowline route selection The routing of subsea pipeline which transports the hydrocarbons from subsea field to onshore is more complicated than infield flowlines. It is necessary to survey a number of alternative routes in order to select an optimum route. The criteria needing considerations are as follow: *Water depth * Seabed roughness and rocks existence. * Crossing of existing pipelines. *Geotechnics of seabed if it is hard or soft. *Fishing activities. *Old minefields. *Trenches. * Shore approaches. * Wave breaking and sediment movements near the shore approach, *Seismic activities. Using survey ships with sophisticated soil analysis labs onboard it is easy to carry out a total route survey to establish both topographical, geotechnical data along the potential routes before final selection. The potential routes for flowlines and pipelines must be surveyed to secure the best locations on seabed. The seabed is surveyed with a number of techniques, the most common is a sonar investigation. From such surveys detailed maps are made showing contour levels and locations of other seabed items or different rock types. This information is used to formulate a detailed construction map for laying process. Further surveys of the line will be carried out after laying and during the line life. Further surveys should be carried out during and after the pipe-laying phase. All records of the final as laid survey should be kept to compare them, as a benchmark, with the future surveys. Video here shows the survey by multibeam data sample. #subsea #subseaengineering #offshore #offshoreoilandgas #offshoreengineering
