Exploration Methods: Gravimetric
It is a natural field geophysical method that assesses the characteristics of the planet's gravitational field to describe the subsoil in terms of density, depth and geometry of rocks. This is done by studying gravimetric anomalies, which are calculated isolating from the measured value at a certain location, the calculated theoretical effect based on a mathematical simulation of gravity for the same location.
Gravimetry is characterized by its efficiency, profitability and versatility, as it requires little staff to acquire data and can be carried out as ground acquisition, marine and airborne.
This method is widely used throughout the range of prospective applications: characterization of the basement in the oil and gas industry, location of cavities for geotechnics, location of bodies with high lateral density contrasts, such as veins and intrusion mining. There are two common ways to apply the method, a - measuring on a profile in those cases where the direction and average dimension of the target is known. The final products are represented in 2D; or b - distributing the data measurementson the surface of the study area, essential in studies where the location of rocks or structures of interest is unknown, or in studies where it is necessary to do mapping analysis to establish and define prospective areas.
The Gravimetric Method is used when providing the following services:
