Instantaneous Spectral Analysis Applied to Reservoir Imaging and Producibility Characterization
نویسندگان
چکیده
Imaging and characterizing fractured shale reservoirs constitute significant challenges. We introduce a workflow and illustrate the application of instantaneous spectral analysis with the aid of a case study on fractured shale reservoirs. With the well log modeling, frequency dependent energy and phase are improved by removing the wavelet overprint. Extracted frequency dependent energy and phase cubes provide an efficient tool to delineate distributions of reservoirs and fault systems. Our results show that the reservoirs distribute along the structure high and are consistent with the paleo-current directions. The attenuation analysis allows observing spectral anomalous variations, representing an alternative tool for hydrocarbon exploration and indirect fracture indicator. Our results also show attenuation anomalies integrated with the production data can guide our predictions of reservoir producibility and indirectly characterize fracture intensity.

Some new coordination compounds of tin(IV) having general formula [SnBu2 (L)2 ] (where L = carbohydrazone ligand) have been synthesized by the reaction of dibutyltin oxide with carbohydrazone ligands with the ratio of 1:2 (metal- ligand) using dry benzene as a reaction medium. The newly synthesized complexes were characterized by elemental analysis, molecular weight determinations, conductivity...
متن کاملIntegrated Characterization and a Tuning Strategy for the PVT Analysis of Representative Fluids in a Gas Condensate Reservoir
Gas condensate reservoirs are characterized by a distinctive retrograde behavior and potential for condensate drop out during production and sampling. Efficient modeling of gas condensate reservoir requires careful phase behavior studies of samples collected prior to and during the production life of reservoir. In this work, an integrated characterization and tuning algorithm is proposed to ana...
متن کاملPore throat size characterization of carbonate reservoirs by integrating core data, well logs and seismic attributes
Investigation of pore system properties of carbonate reservoirs has an important role in evaluating the reservoir quality and delineating high production intervals. The current study proposes a three-step approach for pore throat size characterization of these reservoirs, by integrating core data, well logs and 3D seismic volume. In this respect, first the pore throats size was calculated using...

This paper presents a comparative study between three versions of adaptive neuro-fuzzy inference system (ANFIS) algorithms and a pseudo-forward equation (PFE) to characterize the North Sea reservoir (F3 block) based on seismic data. According to the statistical studies, four attributes (energy, envelope, spectral decomposition and similarity) are known to be useful as fundamental attributes in ...
