An Investigation of Radial Tracer Flow in Naturally Fractured Reservoirs
This study presents a general solution for the radial flow of tracers in naturally fractured reservoirs. Continuous and finite step injection of chemical and radioactive tracers are considered. The reservoir is treated as being composed of two regions: a mobile region where longitudinal dispersion and convection take place and a stagnant region where only diffusion and adsorption are a1 1 owed....

متن کاملAn Analytical Solution for Slug-Tracer Tests in Fractured Reservoirs
The transport of chemicals or heat in fractured reservoirs is strongly affected by the fracture-matrix interfacial area. In a vapor-dominated geothermal reservoir, this area can be estimated by inert gas tracer tests, where gas diffusion between the fracture and matrix causes the tracer breakthrough curve (BTC) to have a long tail determined by the interfacial area. For water-saturated conditio...
متن کاملGeological Characterization Of Naturally Fractured Reservoirs Using Multiple Point Geostatistics
The spatial distribution of fractures in a reservoir affects the displacement of fluids and the prediction of future performance. Realistic characterization of fractured reservoirs requires quantification and classification of fracture patterns on the basis of the underlying geological characteristics and developing reservoir modeling algorithms that can integrate connectivity based (multiple p...
متن کاملCharacterization of Fractured Reservoirs Using Continuous Self-potential Measurements
We have extended our “EKP-postprocessor” (Ishido and Pritchett, 1996) to calculate electrokinetic potentials in fractured geothermal reservoirs that are represented computationally as “MINC” doubleporosity media. In such reservoir descriptions, global mass exchange between adjacent macroscopic computational grid blocks takes place mainly through the “fracture zone”. Inter-block flow through the...
