Development of technologies, growth of trends of reducing impact on environment and challenging tasks, which oil and gas producers face, make introduction of new technologies in seismic exploration field unavoidable. As a key tool of prospecting, exploration and reconnaissance of hydrocarbons, seismic exploration is usually restricted by terrain conditions. Urban, wooded and marshy lands, protected areas, river valleys, mountain areas often make seismic exploration impossible or signifi cantly impact its quality and efficiency.
One of the modern trends enabling resolution of the issues related to impact on environment is to switch to cable-free registration systems (wireless seismic), so called low impact seismic. Due to the use of cable-free equipment, this new technology makes it possible to reduce impact on environment during field works, as equipment is delivered to the place of installation with no special heavy machinery involved.
On the other hand, cable-free systems of seismic acquisition allow to resolve complex tasks of exploration and appraisal studies. Firstly, carry out exploration of hard-to-reach territories, including protected environmental areas, which until now remain unexplored or slightly explored. Managing seismic cables in such conditions is very complicated or impossible. Cable-free technologies allow easily resolving such issues due to both minimum impact on environment and simple and quick placement of receivers. Flexibility and easy scaling of wireless seismic adds to its advantages versus conventional survey. Kilometres of wires are not needed, which allows to easily increase the number of receiver channels and conduct high-density full azimuth seismic survey with single seismic receivers at deep structures, thus, significantly increasing quality of the data received.
The pilot project successfully completed at Khoroshivska area by joint efforts of DTEK Oil&Gas LLC and LLC Denimex Geo LLC confi rms in full advantages of wireless solutions revealing new opportunities for the use of seismic exploration at areas previously hard to reach and allowing implementation of high density acquisition projects.
