Gravity observations provide a measure of the earth’s gravity field, which is sensitive to variation in rock density. Local mass excesses or deficiencies produce, increases or decreases in gravity field. These departures from the immediate background level are termed positive and negative anomalies.
Land Gravity has been used for more than 60 years in oil & gas exploration. Still, under the right conditions data acquired on the ground can achieve the best resolution and accuracy for gravity.
For Land Gravity, RecsaLOG uses CG-5 The Autograv Gravity Meter and LaCoste & Romberg (Type G) for gravity survey, depending on specific requirements.
