An seismic wave generated electrokinetic potential method and geophysical technology for directly locating groundwater aquifers to deduce the associated petroleum hydrocarbon reservoir structure with high accuracy,  low cost,  site access , portability, and simple operational procedures in the field.

The seismoelectric method is different from  conventional  seismic prospecting or  an electrical resistivity survey, which separately register either a seismic impulse velocity or electrical resistivity sounding data in the geological structure. Seismoelectric make use of the different physical character between the ground-flow(water and oil) from the earth solid (rock or soil) to locate ground-flow directly.  

DC-4500 Seismoelectric Ground-Flow Locator receives both a seismic signal and a seismoelectric signal generated by the same seismic source. The penetration of  seismoelectric signal is depend on the power of seismic source. We have got 7000 feet depth reservoir seismoelectric data in LA with a Buffalo gun seismic source. We also have seismoelectric data from 30000 feet depth with a special testing.  

DC-4500 Seismoelectric survey can avoid  dry holes in water well drilling, indicates groundwater in real time analysis. With further data processing and interpretation with the reference application to locate such fluids- crude oil or natural gas .    

Seismoelectric survey can also work with seismic survey. With the same seismic source, we can get both seismic data and seismoelectric data at same time give additional ground-flow information to the seismic survey, with lower cost. To indicate groundwater, seismoelectric signal is around 70% match the well log nearby.   
 
We provide the following types of service:

•  Seismoelectric oil & gas survey
•  Seismoelectric groundwater survey.
•  Combine seismoelectric survey with seismic survey, additional seismoelectric data will show ground-water directly. 
•  Technical training in the use of seismoelectric survey. 
•  Research and development of seismoelectric exploration. 

The DC-4500 is patented both in US and in China.

•US Patent (US 6,476,608).
•China Patent (CN 1392420A).

DC-4500 is used as groundwater survey equipment to a  sub-contractor of  the US NAVY. 
We also service to CH2M HILL, Sinopec, etc. So far we have more than 500 successful projects all over the world.

Seismo Electronics LLC. is an international professional geophysics company. We conduct ground-flow exploration survey; supply seismoelectric instruments and training;   and carry out research and development on Seismoelectronics.

Field operation of the portable DC-4500 is not complicated  as shown in the photo but requires only careful attention to the proper assembly of the components.

The electrodes and geophone are connected by a cable to the DC-4500 computer unit and placed on the ground. The seismic source is generated by either  a mechanical impact such as a sledge 
hammer  (or weight drop) or  an explosive device such as a buffalo gun/12 gauge  depending on the desired  target depth and range of seismic acoustic wave transmission.

The seismoelectric survey also can shear the same seismic source in the seismic survey and carry with traditional seismic survey. That will give more ground-flow information in the seismic interpretation. On another hand, it will give the distribution of ground-flow from the seismoelectric data in the field. That will lower the cost of seismic survey
