Our products can be used to complement other data, such as (micro-)seismic mapping, downhole pressure gauging and tiltmeters. No capital expenditure is needed. In the case of horizontal drilling the mass displacement can follow unpredicted conduction pathways. Subsurface crack propagation and subsequent mass transport can be hard to predict or model.
In both conventional and unconventional plays, local variations in stratigraphy and fault pattern can cause enough variation that model outcomes need continuous fine-tuning.
Any mapping based on satellite images – and displacement mapping in particular – is very information-dense: it typically yields several orders of magnitude more information than conventional terrestrial methods for surveying surface motion.
The availability of all this new data of the earth’s surface motions also enables new, previously unimaginable applications. We make our maps with comparable accuracy, at a lower cost and no capital expenditure. The larger and the more inaccessible the area of interest, the higher the value added by remote sensing.
Surface measurements can help put quantitative constraints on geophysical models. Subsidence bowls tend to be symmetric even where the compaction in the payzone is not. Subsidence effects resulting from each compacting element are superposed, so displacement bowls typically average out variations.
Overburden anisotropy and slippage along fault patterns can affect the spread of displacement. So vice versa, asymmetries in displacement patterns combined with knowledge about overburden anisotropies or fault patterns can isolate “visible” compaction. The SkyGeo horizontal vs. vertical surface motion measurements can further improve compaction estimates thus constrained in the models.
