Geological & Geophysical


A major use of geophysics in engineering investigations is as a tool in unravelling the subsurface geology. In this fundamental and early application, it is the geology that is the target, and engineering considerations and material properties are secondary. The simplest geological structure, which can be investigated, is a horizontal interface such as that between bedrock and overburden. Geological structures are rarely simple, and surveys have to be designed to tackle complex situations.

Geological structure can be considered as lateral variation in the properties of the subsurface rocks. In its simplest form it might be represented by a single dipping or irregular interface such as a bedrock surface. In more complex situations it might include thickness changes, faults, folds, or igneous intrusions.

The first section examines the measurement of depth to bedrock, as this is probably the most common boundary problem. Other geological structures are briefly considered under different types of geological hazard.

Geophysical applications are commonly seen in various industries such as oil well drilling, petroleum, mining, mineral extraction, and metallurgical sector. The science of geophysics involves working with technologically advanced equipment that are capable of being compatible with the seismic waves. These devices require powerful transformers to sustain their voltage maintenance and current generation needs. Custom Coils toroidal transformers are apt for such requirements.

Different Geophysical Applications that Rely on Toroidal Transformers

Following applications are dependent on toroidal transformers in the geophysical sector:

  • Seismic data collection
  • Recording the wave movement in Earths layers
  • Seismic data interpretation
  • Automated thermal printing
  • Seabed seismic data analysis
  • Seismic recording for geophone operation

All these and many more such applications make use of toroidal transformers for effective and efficient operation.These transformers are essential for creating highly powerful magnetic fields that lead in the generation of electrical current. The voltage across terminals is maintained with the help of toroidal transformers. The inductors of these transformers are essential in providing capacitance to the field helping in proficient operation of the high-end equipment and systems used in different geophysical applications.
