Bain Geophysical Services, Inc. provides integrated geophysical and geological interpretation solutions to the worldwide exploration community. Our solutions involve tight integration of your exploration teams’ knowledge, with our unique expertise and tools for interpreting gravity, magnetic and seismic data sets.
Bain Geophysical Services was founded by John Bain who, prior to forming Bain Geo, served as the Vice President of Interpretation Services at Fugro-LCT, after having created and subsequently sold Galileo Geophysics, Inc. to Fugro. Prior to that, John was a key member of the LCT management team, having established their processing and interpretation groups, created their Houston office, and participated in the management buyout of LCT in the role of President. LCT was also later sold to Fugro.
Your Office or Ours!
We work wherever the project team can be most effective – either in your offices, or ours, on a worldwide basis. Our goal is to extend your team, providing you with expert integration of gravity and magnetic data and knowledge, with your seismic and geological interpretation expertise, in the most resourceful manner possible.
Experts in Integrated 3-D Modeling
- Complex salt, carbonates, complicated overthrust
- Using both gravity and Full Tensor Gradient (FTG/Falcon) data, as well as high resolution detailed magnetics
We are experts in 3-D modeling around salt, carbonates, complex overthrust features, etc., using both gravity and FTG/Falcon data sets, oftentimes tightly integrated with seismic velocities.
Depth to Magnetic Basement -
New Twist on Old Methods
One key to obtaining the best interpretive information from magnetic data is computing the correct depth to basement – particularly if your seismic imaging of basement is challenging. We have developed a new depth to magnetic basement tool – MagDepth™, which has numerous methods built in for computing magnetic depth to source, with a key emphasis on properly computing depth with the thickness of the magnetic crust as a built-in constraint. This is especially critical for thin-crust environments.
We have also implemented methods in MagDepth™ to work directly (and correctly) on non-reduced-to-pole (RTP) data. This has been a major step forward in the quality of the depth to magnetic basement interpretations we conduct, particularly in low magnetic latitude regions. Too many methods (including standard tilt-depth, most slope methods, etc.) rely solely on RTP data; a process that inherently distorts the gradients that are so important for correct depth computation.
Survey Design and Quality Control
- Airborne, marine and land gravity/magnetic surveys
- Data processing
Our experts also design and provide quality control for airborne, marine and land gravity and magnetic surveys – primarily for programs that we will ultimately interpret, so that we have the best data possible for our interpretation work. In this way, our experts work closely with your team to allow the geology and exploration objectives to inform the design of an optimal survey.
Our QC is primarily done remotely from the field, where we perform rigorous quality control assessments on the data (daily, weekly, as data drops allow). This allows us to review the data as acquired, and confer with the field and data processing personnel to ensure the highest quality survey results, make recommendations for re-flights, determine chargeable km, etc. Our QC role continues during the data processing phase, oftentimes with a visit to the data processing center to perform final QC, discuss deliverables, etc.
We are experts in using various industry-leading software tools, and have extensive experience with the LCT (owned by CGG) system and the Geosoft (owned by Seequent) suite of gravity and magnetic interpretation modules. Many of our projects use both LCT software and Geosoft, as well as software that we have developed internally to solve specific exploration questions.
Bain Geo’s own software tools include incorporation of a thermal gravity correction (Greenhalgh, Chappell, Kusznir, for example), which can be used effectively in areas of young, thinned crust. Our software has extended the thermal gravity work by others to incorporate the use of multiple Moho tie points during gravity inversion for crustal thickness, along with multi-layered crust models.
BainGeo is pleased to be working closely with Dan Dromereschi for more than 10 years to design and develop the user interfaces for the software tools described above. Click here to learn more about Dan’s services.
Experts in Data Merging
- Data re-processing and merging of large and differing vintages of data
Bain Geo’s team are experts at assembling and merging large and very diverse gravity and magnetic data sets. Whenever possible, we re-process the data to a common set of reduction parameters, including full 3-D terrain corrections (gravity) and common observation levels (drape, level, etc.). We then merge the data sets using combinations of points, lines and grids, to (typically) form a large coverage well beyond the prospect area, so that both regional to prospect scales can be investigated and understood.
