Our Exploration Program Field Work (Geophysical Activities)

QEI Starts Implementation of the Exploration Program and Field Work Activities from 1st of January 2016

Al Qamer for Energy & Infrastructure Ltd is Starting implementation of the exploration program and field work activities, in Attarat umm Ghudran, MoU Area with a QEI’s partner Al Own for Contracting and Mining Company, Ltd. to implement MoU Requirements. and Mazen Rial Expert Decision Engineering Office (MRO).


The TEM source consists of a fast turn-off, high current transmitter driving a large loop placed on the ground. The actual size of the loop depends upon the depth of investigation desired and the amount of area to be covered. A battery-powered transmitter will produce currents of up to 4 amperes in a typical loop. The current is cycled on and off in pulses of alternating polarity. Receiver measurements are made during the off time when only the secondary fields are present. A pulse of energy is put into the ground during the current turnoff time, and the voltage generated in the receiver loop or magnetic coil antenna is measured as the induced energy diffuses into the earth.

Typical time intervals or delays monitored on the decay waveform vary from 30 microseconds to 10’s of milliseconds for mining applications. Each decay waveform is measured with logarithmically spaced data points (time windows) which give a relatively uniform depth measurement as a function of earth’s resistivity.

The first phase of TEM resistivity survey was conducted at Al Qamer oil shale area which was started on site on 14/1/2016 and was completed on 17/1/2016 covering the southern and middle including 27 TEM, four BH-TEM calibration areas.

2. Survey design

The geophysical survey was carried out with a TEM-FAST 48HPC device from Applied Electromagnetic Research (AEMR) (Figure 1), using the coincident loop configuration of 100m × 100m, and an injection current of 1 to 4A. The study area consists of 70 TEM sites and proposed TEM calibration at possible 10 boreholes (i.e. ATO2 and AG36) (Figure 2; Table 1), the grid survey was designed to conduct resistivity at ~1km station-station distance that are distributed evenly to explore possible sites of oil shale occurrence. All proposed TEM sites and boreholes displayed according to Cassini projection type of Palestine grid system.
