Abstract
Making decisions about improving an oil and gas reservoir model
based upon microseismic data is a difficult challenge for reservoir
engineers and analysts. These difficulties arise because the available
data contains inaccuracies, has high-dimensionality and has a
high degree of uncertainty. Currently these difficulties are intensified
by the lack of computational tools to support interactive visual
interpretation and integration of geophysical data leading to robust
structural models of the reservoir and its parameters. To address
these difficulties domain experts are demanding better and more
detailed visualization tools to help them as they explore their data.
In this paper, we present a tool that contains a set of interactive visualizations
that combines, merges and extends existing visualization
techniques. We describe the iterative design process we undertook
to develop the tool, relying on insight from domain specialists. Our
tool supports 3D spatial analysis and exploration of the data with
a set of manipulations designed to provide domain experts with insights
into their highly complex microseismic data. Our microseismic
visual-analysis tool also provides an extended parallel coordinates
implementation to: (1) support interactive filtering and selection
through combined filter and shadow boxes that can remove the
uninteresting events from further analysis, (2) correlate between the
data attributes by axes reordering and outlier discovery, and (3) visually
correlate the data events rendering through additional visual
elements such as color maps. Our multiple coordinated views link
the insights gained from one view with other views instantaneously.
We conclude with a discussion of the feedback provided to us by the
domain experts.
