SPA is based on the application of technologies of irregular observation systems combined with modern hardware and software  means of recording and processing of seismic data.

Advantages of 3-D irregular survey

• Execution of 3-D survey in a limited area (up to 15 sq. km). This is important taking into account a modern level of infrastructure and  increasing quantity of small prospecting objects

• Reduction of time for  the acquisition of geophysical data for 4-6 months from the beginning of field season

• Application of an observation system individually adapted to a definite area and if necessary its effective changes in the field conditions. It leads to the acquisition of 3-D data in the conditions where regular 3-D observations are basically impossible. 

• 30-40% reduction of general expenses for field investigations retaining a high quality of data due to the application of a system of computerized planning, optimization of irregular observations and data processing technique.
