4D Gravity Surveys
4D Gravity Monitoring Onshore and Offshore
Gravity and subsidence sensors used for time-lapse surveys can provide high quality and accurate measurement with respect to resolution, reliability and cost.
REX Geo Solutions can advise on technology and plan surveys to ensure they meet the objectives. Repeat surveys in the North Sea have achieved vertical resolution down to ½ meter in the gas-water contact height, and seafloor subsidence of 2-5 mm precision. The technologies being tested to depths of 3000 m, indicating they are highly robust and capable of providing great clarity into subsidence and density changes in deep water environments.
