this conference proceedings contains 85 papers. some of the topics discussed by the papers are here cited as examples: a case study of reservoir characterization from dst and seismic data; a method to estimate the value of well log information; pressure behavior of laterally composite reservoirs; relating static and ultrasonic laboratory measurements to acoustic log measurements in tight gas sands; scale consistency from cores to geological description; defining flow units in dolomitized carbonate-ramp reservoirs; a comparison of log interpretation to core results using a full element model and a reduced element model in the east texas cotton valley sandstone of gri well no. 3; integrating seismic data in reservoir modeling: the collocated cokriging alternative; geological heterogeneity in the niger delta: a case for additional recovery through a combined effort of geologicall targeted infill driling, stimulation, and gas-lift installation; effect of reservoir stress path on compressibility and permeability of sandstones; the profile permeameter: a new, fast, accurate minipermeameter; and dynamic filtration of invert-emulsion muds
