SqueeSAR™ measures ground response to enhanced oil recovery (EOR) operations and contributes to the development of EOR strategies.

EOR operations can induce surface deformation in both expected and unintended areas. SqueeSAR™ is used to identify areas of deformation and determine the surface and subsurface impacts of EOR activities thereby assisting in site production optimization.

Fluid Migration Tracking
Ground displacement measurements incorporated with subsurface models provide an overview of fluid-flow migration within EOR reservoirs. Regular data acquisition provides an ideal tool for mapping preferential fluid flow paths and fluid propagation within the reservoir over time.

The high spatial density of ground points may also allow for the detection of potential reservoir leakages.

Refining EOR Strategies
Surface deformation measurements, used as input to geomechanical subsurface models, highlight the reservoir boundary and allow for the calculation of reservoir volume, pressure distribution and permeability. 

Ground deformation measurements are beneficial for the development of effective EOR strategies by providing regular updates of surface deformation patterns, enabling engineers to optimize production and identify potential problems before production is threatened.

Ground Response Monitoring
Although SqueeSAR™ measurements complement data obtained from traditional ground-based surveys, both the spatial extent and density of ground points is on a significantly larger scale. Ground displacement maps highlight spatial patterns in surface subsidence, identifying both known and unknown active fault / fracture systems, whilst also improving knowledge of the reservoir structure.

This technique holds promise for the detection of surface deformation caused by hydraulic fracturing (fracing).
