Field-work automation of hydrocarbon exploration using a passive seismic-electric method

Abstract

The paper proposes to exclude the active source of the seismic field from the measurement scheme, which is often a massive truck with equipment installed on it, which in its turn makes it difficult and increases the cost of field-work. The proposed passive measurement installation allows the detection of hydrocarbon deposits by registering the natural fields of the Earth. All measurements can be carried out by one person due to the use of magnetic antennas. A method of field measurements by means of such installation, as well as measurement data on a real gas condensate field are presented.

Study of the Seismoelectric Effect of the Second Kind Using Molecular Sensors

“…As shown in Table 2 , obtained in 2019–2020, the experimental data confirmed the results of the measurements in 2014–2018 [ 27 , 28 , 44 , 45 , 46 , 47 ]. Figure 9 b also shows a curve obtained by solving Equations (1)–(8), according to which the values of the electric field strength E will correspond to the magnitude of the observed SE effect on the day surface.…”

“…This was the first attempt to process data obtained in different years of observation. Based on the experience of [ 27 , 28 , 44 , 45 , 46 , 47 ] on this profile, it can be concluded that the amplitude value of the observed cross-correlation coefficient on the Earth’s surface depends on many factors. Thus, the absolute value of this coefficient cannot be used for the assessment, and, therefore, the shape of the resulting curve is a more important factor.…”

“…At the same time, as induction geophones, the same ones in the experiments on observing the SE phenomena (2014–2018), namely GS-ONE [ 43 ], were used. The measurement scheme is shown in Figure 7 [ 44 , 45 ].…”
