INNOVATIVE TECHNOLOGY OF DIRECT OIL LOCATION
VERTICAL ELECTRIC CURRENT SOUNDING IS A KEY TO HIGHER EFFICIENCY OF EXPLORATORY DRILLING
As a result of long-term investigations, modeling, real field works, processing, and interpretation of the field work results acquired during prospecting and exploration of oil accumulations, ore deposits and kimberlite bodies, the inference can be drawn that the vertical Current Sounding (VECS) is a high efficiency technology in acquisition of local targets.
When the VECS method is applied for petroleum prospecting and exploration, the presence of hydrocarbons is predicted with high probability in targets intended as promising by seismic surveys. Efficiency of exploration drilling may be eventually increased (the efficiency of which is now no more than 60-65%). In this case, a possible oil outline is defined more accurately and locations of most hydrocarbon accumulations are predicted due to which the direction of drilling may be specified more exactly.
The VECS electrical exploration does not compete with seismic survey, but can essentially compliment its results. As an example, VECS works at fields of oil specified the range distribution of hydrocarbons and locations of their greatest accumulation.
Presently the VECS method has been transformed into a valuable prospecting and exploration technology for areal measurements.
The VECS method refers to the area of high-tech technologies. The powerful axially symmetric source, environmental compensation, and dense areal measurements applied in prospecting and exploration works have revealed the very positive effect that cannot be presently explained. The VECS technology can be successfully applied at the shelf of arctic seas in the regions with covered polar ice where applying seismic survey faces a serious problem.
In prospecting and exploration of kimberlite bodies, the VECS method is much more efficient than the TEM in the sense of resolution, the degree of detail, depth and area of investigations, performance, and presentation of prospecting and exploration results. Measurement of the additional (horizontal) component of an electromagnetic field allows even more accurate identification of a sought target.
The VECS technology includes:
- operation with surveying system,
- acquisition technique,
- modeling, processing, and interpretation.
STC “ZaVeT- GЕО” can undertake field works applying the VECS technology by request of organizations concerned at an agreed price.
SТC “ZaVeT- GЕО” will supply the VECS technology to organizations concerned (firms and companies) at an agreed price including:
- manufacture of surveying system,
- personnel training,
- execution of work (under a separate contract) on the area required to confirm the technology efficiency;
- providing nonexclusive license throughout Russian Federation.
The VECS technology is supplied in two versions:
- VECS technology for prospecting and exploration works on oil;
- VECS technology for prospecting and exploration of ore and kimberlite bodies.
The method and technology of VECS require follow-up investigations. New opportunities are opened when multi-component measurements for solving a problem of three-dimensional structure of a geologic medium are carried out and more powerful sounding setups for increase of the depth of investigations and setups with operating voltage more than 1000 V for operation in areas with low conductivity of a host medium are developed. Applying the VECS method in the frequency mode of electrical exploration is promising. Organizations, companies, and firms are invited to take part in further investigations.
