Exploration

Petro-Drill Global is in an exclusive partnership with Geo Exploration Services a German based Hydrocarbon exploration survey company with vast knowledge and experience in detection of Oil and Gas and Solid minerals deposits. This advanced method of exploration is very accurate, precise and very affordable with a quick turn around time of results delivery without harming the environment nor obtaining environmental permits and clearance as is observable with other on the ground exploration seismic systems.
Onshore and Offshore Exploration of Oil & Gas Reservoirs HYDROSCAN® is an innovative helicopter-based passive seismo- electromagnetic exploration technology which is used to detect hydrocarbon (HC) accumulations up to depths of more than 4,000 m. 3D imaging enables mean depth and multi-reservoir indication. For all tasks the HC reservoir identification capability includes conventional (anticlinal) traps as well as unconventional non-structural related traps, like occurrences in stratigraphic closures, fault zones, sub-salt and sub-basalt.
Airborne Seismo- Electromagnetic Method The development of the proprietary system is based on research results obtained over oil and gas fields, where it is found that specific low-frequency (LF) electromagnetic (EM) power spectra are largely raised as compared to dry and tight rock mass. The observed diagnostic signal data can be related to an electrokinetic conversion associated with HC/brine reservoirs. Thereby ocean-wave generatic seismic earth noise is the driving excitation force which is changed into an electromagnetic field radiation under the influence of the geomagnetic field. Thus, a HYDROSCAN survey enables the discrimination between presence and absence of transmissible (productive) HC reservoir zones. The signal intensity is proportional to HC saturation, permeability and pay thickness expressed by the HC transmissibility which mainly influences the HC productivity of a well. It opens a wide range of highly beneficial usage, from frontier exploration to field extensions, from prospect de-risking to seismic interpretation support, and from optimization of well placement to reservoir time-lapse monitoring.	Typical frequency spectra indicating no-HC and HC reservoir zones Seismo-EM system equipped at helicopter 3D imaging enables mean depth and multi-reservoir indication.
