Traditionally, this has been done using a technique called inversion, which has been well described in the literature (e.g. INTRODUCTION The classical problem in seismic exploration and production is how to integrate seismic data, which is spatially closely sampled but of relatively low resolution, with well log data, which is of high resolution but is poorly sampled spatially.
Commercial PRIMA processing modules and features are written in same programming. Nutec Energy Services was acquired by TGS in 2004. Current commercial version of PRIMA is V20.0 and was compiled September, 2018. We illustrate this technique with a 3D channel sand example from Alberta. PRIMA is a multifunction exploration software package that incorporates: PRIMA originally developed at Nutec Energy Services in 1997. In this paper, we propose a new technique that incorporates both multiattribute transforms (either linear or nonlinear) and geostatistics. second approach is model-based inversion technique (Russell and Hampson, 1991). These approaches include geostatistical methods such as kriging with external drift (KED) and cokriging, multilinear transforms involving seismic attributes, and neural networks. More recently, statistical techniques have been applied to the problem. The integration of well log and seismic data has traditionally been done using deterministic model-based approaches such as acoustic impedance inversion.
