Scroll down for an informative video and a tour of the work that goes into the process. ![Acquisition with Bell Geo](https://www.bellgeo.com/hubfs/Untitled%20(5).jpg) ## Data Acquisition with Bell Geo ### Fast, reliable, high resolution data acquired passively and safely.  Bell Geospace airborne geophysical surveys are built to deliver rapid, high-resolution insight from the very start of acquisition. Using industry-leading Full Tensor Gravity Gradiometry (FTG), our aircraft capture precise measurements of subsurface density variations, revealing geological structure with exceptional clarity. From the first lines flown, interim results begin to illuminate basin architecture, fault systems, and prospect-scale features. This early visibility enables exploration teams to adapt in real time, refining targets, optimising survey design, and directing investment where it matters most. Through advanced processing, inversion, and interpretation, Bell Geospace transforms raw airborne data into actionable geological understanding typically within weeks, accelerating decision-making and reducing exploration risk.   ![First Steps](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Aoi.jpeg) ![Feasibility Study](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Fesibility.jpg) ![Operational Setup](https://www.bellgeo.com/hubfs/m_limit-IMG_1873.jpg) ![Survey Planning](https://www.bellgeo.com/hubfs/m_limit-Survey_planning.jpg) ![Acquistion](https://www.bellgeo.com/hubfs/m_limit-Acquisition.png) ![Infill & Interims](https://www.bellgeo.com/hubfs/m_limit-Interims2.png) First Steps A need to better understand the geological situation in your area of interest (AOI) is identified. This may be an underexplored frontier region, an area that is difficult to access on the ground or somewhere that seismic acquisition has issues resolving structures. Whatever the reason, FTG data has the potential to help further your understanding of the underlying geology. After initial conversations about your particular situation, a shapefile or coordinates of the AOI are gathered to locate the survey. From there we can build a rough survey plan to give an estimate of cost. ![Data Acquisition - First Steps](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Aoi.jpg) Feasibility Study If the geological challenges are well understood and a cross-section/seismic image can be provided, a feasibility study is created based on that understanding. This takes into account the unique properties of FTG acquisition along with target depth, size and density contrast. From this data, we can recommend a survey line spacing which will meet your geological needs while not acquiring unnecessary lines that inflate the project cost. ![Data Acquisition - Feasibility Study](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Fesibility.jpg) Operational Setup Before commencing a survey we will do some basic checks to make sure we can operate in your area of interest. Our checklist includes, but is not limited to: - - Fuel availability - - Airport location - - Ferry distance to AOI - - Accommodation availability - - Security We have three Basler BT-67 aircraft in our fleet. With their long-range fuel tanks and excellent cargo capacity, there are few places around the world we cannot operate. Successful surveys in remote areas include: - - Svalbard and Greenland - - Somaliland - - Uganda - - Australia – Northern Territory - - Canada - Yukon ![Data Acquisition - Operational Setup](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-IMG_1873-1.jpg) Survey Planning With the information from a feasibility study or general knowledge about the geology within the AOI, the ideal line spacing can be determined. At this stage a Bell Geo geoscientist will use various data sources to plan the survey based on terrain data, population density, country borders and restricted areas. In an ideal world, the survey area would be near an airport, a regular shape with long lines and over flat terrain or water. However, as survey AOIs rarely come with these properties we will work with you to put a plan in place which meets your geological needs while ensuring we comply with our HSE guidelines for a zero-incident project. ![Data Acquisition - Survey Planning](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Survey_planning-1.jpg) Acquistion Data acquisition flights commence as soon as possible after initial calibrations and clearance from local aviation authorities.

We will generally provide these images once every third of the lines are complete – we call these thirds ‘interlaces’. This allows the option to plan targeted areas in the original AOI or extensional areas outside if the geology dictates. ![Data Acquisition - Infill & Interims](https://www.bellgeo.com/hubfs/BellGeospace_June2022/image/m_limit-Interims2.png) ### Do you want to know more about how we can help your business?
