SeisART software: seismic facies analysis by contributing interpreter and computer

Abstract

In this paper, an interpreter computer interactive software, named SeisART, is introduced which is employed for seismic facies analysis. Seismic facies analysis is considered as a technique for mapping geological changes using seismic data. In recent years, the number of seismic attributes and the size of seismic data have been increased. Therefore, the interpretation of seismic facies has become a more elusive issue. In a seismic facies analysis procedure, there are three main steps: (i) selecting appropriate attributes as the feature extraction task, (ii) defining the proper number of clusters, and (iii) utilizing an appropriate pattern recognition method. Interpreter plays a remarkable role in performing these steps, based on his/her knowledge, and also available tools and geological information. SeisART as a package-deal software includes numerous methods of feature extraction, validation, and pattern recognition. In a user-friendly environment, the interpreter is able to employ these utilities along with well-designed visualization tools for choosing the best methods to obtain and compare numerous results. Besides, owing to the uncertainty of seismic data, SeisART employs the Fuzzy system to gain more confidence with the seismic facies interpretation.
