Due to the limitation of seismic resolution, resolving a thin reservoir from seismic alone is difficult. Geostatistical seismic inversion provide solution to this issue by integrating the geostatistical model from well logs and other inputs along with the seismic data to map facies below seismic resolution.
On-shore data. Middle & right are results from a study where geostatistical inversion (right) was able to map the thin sand better compared to deterministic inversion (middle). The probability of sand (right) shows how geostatistical inversion reduces risk and uncertainty in mapping that sand.

NeuEra Petroleum also offers other types of inversion such as colored inversion and extended elastic impedance (EEI) which fit an exploration team where not enough well data is available to perform deterministic inversion.
Lancaster and Whitcombe (2000) published a fast method for band-limited inversion of seismic data known as colored inversion (CI) that generated widespread interest among interpreters. we describe all the steps to go from reflectivity data to inverted cubes:
