... the transition zone. This often means dividing the field into smaller areas where the formation is seen to be consistent. R v and R h curves are computed from conventional resistivities and modelled anisotropy, while R v _sh and R h _sh values are determined from resistivities in thick shale sequences...

... Abstract A pragmatic technique has been developed to accurately determine the total organic carbon (TOC) content in shale formations by analyzing well logging measurements. More specifically, a generalized equation has been proposed firstly to determine the positive separation (i.e., Δlog R...

... Abstract In petrophysical evaluation one of the most common procedures of zoning into shale and sand layers is to use GR logs. In this study an alternative zoning approach was proposed, using the Vp/Vs log curves. First, Vp and Vs were calculated based on the sonic slowness log data (DT...

... (Sequential Indicator co-simulation), is employed in this study. In COSISIM, probabilities of sand and shale, which are derived from well logs and seismic, are used as soft data. We create 25 heterogeneous models for the inputs of the flow simulation. The results indicate the large variations or uncertainty...
