The results of the investigative efforts for this jointly funded DOE-State of Texas research project achieved during the 1991-1992 year may be summarized as follows: Geological Characterization - Detailed fracture system maps measured at outcrops along the Austin Chalk trend have been related to the subsurface. Statistical data obtained from the outcrop studies has been correlated with FMS dipmeter information obtained from Austin Chalk operators. These studies have shown the hierarchical nature and the bed contained fracture development observed in the outcrop may be extrapolated to the subsurface. Well-log response in Austin Chalk wells has been shown to be a reliable indicator of both organic maturity and fracturability. Multi-component, vertical-seismic-profile. VSP shear-wave data were reduced to their true orthogonal components by balancing or rotating the source magnitudes and geophone couplings. The resultant method appears to be useful to detect the negligible displacement fractures in the Austin Chalk. Production decline curves have been related to well test or transient pressure analysis methods. Studies on daily production records of Austin Chalk horizontal wells have shown that analysis of production records may be substituted for the more expensive and difficult to obtain transient pressure data. Development of the EOR Imbibition Process - Magnetic Resonance Imaging. MRI studies have shown the carbonated water-imbibition displacement process significantly accelerates and increases recovery from oil saturated, low permeability rocks. These studies applied to flow in open and dead-end micro-fractures have shown significant volumes of oil remain undisturbed in the dead-end micro-fractures even when carbonated water is used as the imbibing fluid.
