Ryder Scott performs geological analyses of fields and regions worldwide—from basin evaluations to production geology. The firm uses stratigraphic and structural analyses and the latest computer-mapping programs and techniques to help unravel structurally complex geology. The firm generates isopach and structure maps to better understand depositional environments and to define subsurface traps. Reservoir characteristics typically mapped include net and gross reservoir thickness, water saturation, porosity and pore volume. To produce a geologic model, Ryder Scott matches core and log data with the seismic stratigraphy and projects extensions of stratigraphic sections in unexplored areas. Ryder Scott integrates geological studies with geophysics, petrophysics and fluid properties to estimate the volumes of oil and gas in place.
