Geological Trend versus Mathematical Trend: Introducing a High-Resolution Approach to Subsurface Structure Mapping using Well-log Data and Geospatial Analysis
نویسنده
چکیده
In general, the conventional approach to structure study uses potential-field data, including aeromagnetic and gravity data, for detecting the basement structures, and geophysical well-log data (combined with seismic data when available) for interpreting the sedimentary cover structures. With respect to well-log data, the main approach is to interpret faults from isopach and structure-top contour maps. For example, descriptions of structures related to the PRA-PRE, as presented by DeMille (1958), Lavoie (1958), Williams (1958), Sikabonyi and Rodgers (1959), Jones (1980), Cant (1988), Barclay et al. (1990), Dix (1990), O'Connell et al. (1990) and O’Connell (1994), are all based on use of well-log and sedimentological data to identify fault locations and trends, as well as magnitudes and types of offset.

Water saturation determination is one of the most important tasks in reservoir studies to predict oil and gas in place needed to be calculated with more accuracy. The estimation of this important reservoir parameter is commonly determined by various well logs data and by applying some correlations that may not be so accurate in some real practical cases, especially for carbonate reservoirs. Sin...
