Title: Interactive Color Previous HitDisplayNext Hit and Analysis--Added Dimension to Previous HitSeismicNext Hit Interpretation: ABSTRACT

Article Type: Meeting abstract


Interactive color video Previous HitdisplayNext Hit systems provide a new dimension to the analysis of Previous HitseismicNext Hit Previous HitdataNext Hit. Subtle concurrent changes in multiple Previous HitseismicNext Hit parameters such as reflection strength, velocity, frequency, and structure can be assimilated more effectively with the aid of interactive color technology. We examine here two typical interpretation problems--bright spots and 3-D Previous HitdataNext Hit--and illustrate the use of interactive color Previous HitdisplayNext Hit and analysis in formulating a solution. The successful analysis of hydrocarbon indicators relies on both the ability to measure the auxiliary effects that hydrocarbon indicators have on Previous HitseismicNext Hit Previous HitdataNext Hit and to Previous HitdisplayNext Hit these effects in a form that is visible to the interpreter. If the interpreter can view an optimum combination of subtle changes in thes parameters, his ability to predict both the lateral extent of the reservoir and the amount of gas saturation can be substantially improved.

One way to Previous HitdisplayNext Hit simultaneous variation in several Previous HitseismicNext Hit parameters is through the use of an interactive color imaging system. After digital displays of the Previous HitseismicNext Hit reflection Previous HitdataNext Hit variables are input, color assignments are made interactively among the Previous HitseismicNext Hit variables and the primary colors. This process can vary from a simple assignment of a primary color for each variable to a more complex analysis technique that dynamically assigns proportions of the Previous HitseismicNext Hit variables to all colors. Unlike some approaches that "color" a single parameter to better illustrate its dynamic range, the methods described here use color to illustrate the simultaneous changes in all variables. These video imagery systems provide flexible, high-resolution displays that can cope visually with large volu es of Previous HitdataNext Hit that are typical for 3-D surveys. It allows the interpreter to perform a variety of instant, on-the-spot enhancement techniques. Thus, the technology significantly minimizes some of the problems in dealing with 3-D Previous HitdataNext Hit. Typical vertical sections or horizontal time-slice displays from a cube of 3-D Previous HitdataNext Hit can be shown in a variable intensity mode. The horizontal Seiscut displays can be viewed in a flexible and easily controlled movie fashion or overlaid in color to enhance delineation of structural features. When the multiple parameter technique is employed on the Seiscut Previous HitdisplayTop, it produces an "instant geologic map." Each lithologic unit boundary can be distinguished by its unique color pattern.
