Seismic Facies Characterization by Scale Analysis
Over the years, there has been an ongoing struggle to relate well-log and seismic data due to the inherent bandwidth limitation of seismic data, the problem of seismic amplitudes, and the apparent inability to delineate and characterize the transitions that can be linked to and held responsible for major reflection events and their signatures. By shifting focus to a scale invariant sharpness ch...
متن کاملSeismic facies characterization by monoscale analysis
Relating sedimentary records to seismic data is a major challenge. By shifting focus to a scale-invariant sharpness characterization for the reflectors, we develop an attribute that can capture and categorize the main reflector features, without being sensitive to amplitudes. Sharpness is defined by a scale exponent, which expresses singularity order and determines the reflection signature/wave...
متن کاملRock physics based facies classification from seismic-inversion results in unconventional reservoirs
The objective of this study is to demonstrate the power of integrating rock physics theory, measurement and simulation to improve facies prediction in an unconventional limestone and shale reservoir. Reliable facies prediction is a challenge in unconventional reservoir characterization because of complex geological heterogeneities. Both deterministic and probabilistic approaches are commonly us...
متن کاملFacies Classifications for Seismic Inversion
Identifying facies for classification for a seismic inversion project is an important step where one balances computational effort and the quality of the results. We propose a new measure to quantify the suitability of a given facies partition based on information theory. The results depend on a user-selected cutoff, and we propose a reasonable value for this constant. We also show the analysis...
متن کاملAn Integrated Approach for Facies Characterization in Raageshwari Deep Gas Volcanic Reservoirs, Barmer Basin, India
Barmer Basin is one of the most prolific hydrocarbon basins of India having more than 30 discoveries to date. The Raageshwari Deep Gas (RDG) Field, situated in the southern Barmer Basin, was discovered in 2003 by exploration well Raageshwari-1 and is a part of RJ-ON-90/1 contract area operated by Cairn India. This field is characterized by tight gas-condensate reservoirs with excellent gas qual...
