3D Inversion of Ultradeep Electromagnetic Data, the Key to Understanding Complex Subsurface Geology
Offshore Technology Conference Asia, 2020Abstract In complex reservoirs, the position of geological and fluid boundaries can vary significantly in all directions; for comprehensive reservoir understanding and optimal placement of the wellbore, these boundaries should be mapped and understood in three dimensions (3D).

AbstractThe small‐scale discontinuous and inhomogeneous geologies, such as tiny faults, cavities and fractures, play an important role in reservoir analysis. However, effectively extracting them from seismic imaging data is a challenging problem, as their seismic responses are much weaker than reflections' from large‐scale structures. On the other hand,

Magnetic surveys of sites contaminated with unexploded ordnance (UXO) locate ferromagnetic sources and discriminate between UXO and some non-UXO (clutter) that can be left in place. High-pass, two-dimensional (2-D) intra-inversion filtering (IIF) is introduced as a partial solution to the vexing problem of overlapping fields of UXO, clutter, and ...

A simple mathematical inverse method has been developed to correlate two time series Y1(x1) and Y2(x2), where these two signals are related to each other by a mapping function x1(x2). The mapping function describes differences between the two signals and is parameterized in terms of a sum of simple functions of unknown coefficients, ai.
