Abstract

Time Lapse microgravity represents a development of gravity methods. The microgravity change due to fluid movement in the subsurface is very small, therefore special equipment and strategic surveys are required. Simulations of response microgravity anomalies must be done in order to know the time interval period of measurement and the specification of the gravity meter which must be used. Gravity meter: Graviton-EG Meter, Scitrex-CG5 and of Lacoste & Romberg type G and type D with Alliod 100 system are very good for the survey of microgravity. In every period, the measurement sequence of microgravity must be fixed, since every gravity station in one loop can see similar drift correction. Corrections of tidal gravity observations and theory give different results of amplitude or period, so tidal correction must be observed.
