Results of experimental magnetic gradient mapping, with small set of the field detectors (Az = 1.8 m). Are presented field measurements complemented by 2-D modelling of magnetic effects have given the estimation of a magnitude of anomalous field, which can be registered above oil and gas deposits. The data for modelling were obtained from laboratory measurements of magnetic susceptibility of near-surface strata above Radlin gas deposit.
Basing on the relation between amplitude of the anomaly and thickness of the generating anomaly stratum it is shown that such kind of anomaly could be registered in magnetic measurements. Apart of that both above Radlin gas deposit and above the second object in region of Lubaczow magnetic gradient anomalies were find experimentally in the range 2-4 nT. |
