Use of ground‐penetrating radar for 3-D sedimentological characterization of clastic reservoir analogs

Abstract

Clastic reservoir analogs based on 2-D outcrop studies provide valuable definitions of geometric and petrophysical heterogeneities at interwell scales. Integration of 3-D ground-penetrating radar (GPR) surveys with sedimentological and stratigraphic data provides information on the internal heterogeneities of sedimentary sequences at scales that allow dissection of the 3-D anatomy of clastic depositional systems. Two 3-D GPR data volumes were acquired in the Ferron sandstone of east-central Utah. The data show prominent lenticular features, a variety of lithologies, and structural elements such as channels and shale drapes that match well with those seen at the same stratigraphic levels in adjacent cliff faces.

Extrapolation of depositional geometries of the Menorcan Miocene carbonate ramp with ground-penetrating radar

“…GPR represents an inexpensive and fast reconnaissance technique with high resolution of the shallow subsurface. GPR has been established as a standard too for the examination of siliciclastic sediments and rocks (e.g., Huggenberger et al 1994;Stephens 1994;Bristow 1995;Asprion and Aigner 1997;McMechan et al 1997;Corbeanu et al 2001;Buynevich and Fitzgerald 2003). In contrast, the application to carbonate rocks still is far from routine.…”

The location and mapping of ancient ruins on the castle of Lefkas (Greece) by resistivity and GPR methods

“…In Figure 8 the image of the resistivity distribution in the blocks m6 and m7 is presented in greyscale form. In order to present the GPR data in a comparable form, time slicing was performed in the radar data of the same area (Goodman et al, 1995;Malagodi et al, 1996;Daniels et al, 1997;McMechan et al, 1997). The radargrams were first processed along the baselines described in an earlier paragraph.…”

“…Reservoir analog based on outcrop studies provides definitions of geometry and heterogeneities at interwell scales and characterizes reservoirs [24]. A subsurface reservoir model using outcrop analog [25] is employed for an understanding of geological parameters associated with reservoir and at 4…”
