UAV-mobile geophysical complex for oil and gas exploration and production

Posted by Center for Technology Transfer and Commercialization of Novosibirsk State UniversityResponsive · Innovative Products and Technologies · Russian Federation

Summary of the technology

NSU developed a UAV-mobile complex for geophysical research. It uses a high-frequency and highly sensitive vector magnetometer, gamma-spectrometer, gas analyzer, as well as special software for data processing, which creates a high-precision description of the depth of occurrence and morphology of magnetic anomaly with the size of up to tens of centimeters and less. Due to this, the costs of exploration are significantly, often more than 10 times lower than using conventional methods.

Description of the technology

Due to the significant growth in demand for minerals in the twentieth century, geological exploration has intensified significantly, resulting in the discovery, commissioning and development of many mineral deposits. To date, most of the "convenient" deposits in the immediate vicinity of settlements and transport routes have already been found and are being developed.

In this respect, modern geological exploration mostly deals with work in hard-to-reach areas (mountains, taiga, jungle, tundra), as well as on terrain, where it was difficult or impossible to conduct it earlier (swamps, lakes, deserts). Even with the use of modern high-performance equipment, the cost of these works is extremely high, primarily due to the high cost of preparatory work (surveying, cutting down vegetation along the profile) and ground survey, as well as low productivity of exploration on complex terrain.

The use of the UAV, in particular, for magnetic survey does not allow to completely get rid of the ground stage of the works because of the low resolution of the current generation of devices (with the help of the UAV now it is possible only to somehow lessen the amount of foot surveys). Low polling frequency does not allow modern magnetometers to create more detailed maps than 1:10000 with the help of UAV or other type of aircrafts, while 1:5000 and better is required for field development.

The proposed complex will create detailed maps with scale up to 1:200, not requiring any additional ground survey. The system will include a set of sensors and special software, which, based on the information from the sensors, will predict the size, shape and depth of the occurrence, for example, of the ore body or other object, which even slightly distorts the natural magnetic fields. In this case, the size of the object may be 10-30 centimeters. Sensors will be carried by light and super lightweight UAVs, which will carry out a fully automatic survey of the territory, returning to the base only to replace the battery and transfer the collected data. Due to the high degree of automation it is expected that the operation of the complex will be very inexpensive: at least three times less than the traditionally used methods of ground exploration, and taking into account the savings due to the reduction in the volume of drilling and ancillary work (topographic survey, cutting profiles, etc.) savings on exploration work on individual projects can be up to 80 - 90%

The innovation lies in the combination of highly efficient sensors and special software for processing the collected data, which allows us to obtain a very detailed description of the depth of occurrence and morphology of magnetic anomaly, which is unattainable for the current generation of UAVs:

Highly sensitive high-frequency vector magnetometric channel with a mass of ~0.6 kg. Sensitivity up to ±0.07 nT at frequencies up to 3000 Hz.

Software for interpretation and visualization of geophysical measurement data, which allows calculating the depth and morphology of the magnetic anomaly using the information obtained from the magnetometer and other sensors of the complex.

Ultra-light UAV with a low level of magnetic noise

High-precision gas analyzer (methane, 1 - 1000 ppm).

Light Gamma - spectrometer (0.05 - 3 MeV)

The following services can be provided to oil producing, exploration and service companies:

1) Search and exploration of oil and gas fields on the basis of separation of magnetic anomalies over the oil layers and on the water-oil contact area within the oil reservoir, as well as ring anomalies of gamma-ray spectrometry and ring-shaped geochemical anomalies (methane, propane, butane, gas factor detection)

2) correction of hydrodynamic models and schemes of development of oil and gas fields with complex reservoirs on the basis of direct local determination of permeability using magnetometry data;

3) monitoring of hydraulic fracturing efficiency using magnetometry data;

4) monitoring the efficiency of field development scheme selection, localization of remaining reserves using magnetometry data;

5) monitoring of unauthorized taps into pipelines using magnetometry data
