MODE AND ARRANGEMENT FOR DETERMINATION OF CHARACTERISTICS OF UNDERWATER OR UNDERGROUND RESERVOIR Russian patent published in 2005 - IPC

FIELD: geophysical reconnaissance.

SUBSTANCE: alternating in time electromagnetic wave field is transmitted with the help of at least one transmitter on the transmitting frequency from 0.1 to 1 kilocycle to strata containing a reservoir. Detection of an responding electromagnetic wave is carried out with the help of at least one receiver. The transmitter and/or receiver is located at the bottom of the sea or nearby or at the bottom of an other basin. Analysis of effects caused by reservoir on the characteristics of the detected field is made for determination of the content of the reservoir on the basis of this analysis. Preferable distance 1 between the transmitter and the receiver is 1=2s=2λ, where s - the distance between the sea bottom and reservoir, λ - the length of the transmission of the wave through covering layers.

EFFECT: high possibility of determination of reservoir characteristics without well-boring.
