Annoucement December 13th 2021. A New Airborne Geophysical Survey for Southwest England Begins This Week.

Press Release / Julianne Sharples / 2021
Bell Geospace, an Edinburgh-based airborne geophysical surveying company, is commencing operations this week in the Southwest of the England. The survey will take two to three weeks and involve a plane flying in straight lines at an average height of 200 meters to collect geophysical information on the properties of rocks below the ground. The information being collected creates geological maps. These maps may be used for planning geothermal resources in the area or by domestic mining companies tasked with future-proofing the supply of critical minerals needed to build net-zero economies. The airborne survey involves measuring minor variations in the Earth’s gravitational field. Sensitive measuring equipment located in the aircraft will be used to gather this data. It is a totally passive technique which does not involve sending out any signals or sound waves. Bell Geospace is one of the only two contractors in the world that can do this type of survey. They have been in the geophysical surveying business for over twenty-five years, have an unblemished safety record and an experienced field and office crew. Flights will take place early morning, with take-off at around 6am. Flights typically last between four and five hours. Livestock owners and parishes in the area are being contacted by mail and social media. it is possible for residents and any interested parties to find out more about the survey at info.bellgeo.com/cornwall_faq or by calling the Bell Geospace community helpline, 0131 202 7144.

How FTG Can Rejuvenate Old Seismic Data

Journal / Julianne Sharples / 2020
One of the prime uses for FTG technology is that it can be used to rejuvenate old seismic or poor quality seismic. This function of FTG has become especially important in recent years. In fact in the downturn of 2011, an Operator reported that instead of starting from scratch and shooting three dimensional seismic, they took their old two dimensional data set and flew some new FTG. They managed to get incredible results, while spending only around 3% of the cost

Gravity Gradiometer Design Comparison by Three Different Methods

White Paper / James Brewster / 2018
Differing gravity meter designs exist; two gravity gradiometer designs are currently available for commercial survey operations and other instruments are in the late stages of pre-deployment research. These gradiometer systems differ from one another with respect to the number and orientation of sensing accelerometer pairs. There is a need for a theoretical framework to evaluate how these design variations affect the expected performance of these devices

Source Body Migration Imaging of the SEAM Salt Body Model

White Paper / James Brewster / 2017
The paper presents a discussion of source body migration as a method of converting gravity gradiometer survey measurements to a three dimensional density image. At the core of the method is the concept of upward continuation of density, which due to the non-uniqueness of potential field data does not change the observed field values. The workflow uses a combined iterative process of source body migration followed by density continuation and is demonstrated using a simulated gravity gradiometer survey data set generated using the SEG SEAM salt body model.
