Theoretical calculation shows the anomaly of reservoir tidal gravity is measured at μGal level, while the measured data shows the observation error of such tidal gravity at 10-μGal level. This indicates that the data noise may well disguise real anomalies, and therefore that the lack of measured anomaly data does not necessarily equate to the lack of oil and gas reservoir underneath. The actual observed tidal gravity anomaly can reach tens of μGal. Though it is more than three times the observation error, we can not attribute it to the reservoir-induced tidal gravity anomaly.
