Abstract: The Role of 
Well
Pix in Correlating Well Logs and
Constructing a 3D Sequence Stratigraphic Framework of the South Marsh Island
Area, Gulf of Mexico
Construction of a 3D sequence
stratigraphic framework model adds valuable information to the evaluation of
the quality of potential hydrocarbon bearing reservoirs. Analysis of rock
facies distribution, facies relationships, interpretation of stratal geometry,
as well as the analysis of petrophysical parameters, such as porosity and
permeability, is routinely done using a variety of well log interpretation
methods. In producing fields, wells frequently cover the entire area of
interest; and with an increasing number of wells and well logs it becomes
increasingly cumbersome to perform these tasks without using analytical,
computational, and visualization software. In this work we use WellPix, a
correlation tool utilizing variable area coloring, to demonstrate how such a
visual aid helps to enhance the graphic representation of stacking patterns.
The software is applied to the South Marsh Island, Gulf of Mexico area; and
specific recognizable patterns are discussed in relation to depositional
facies, sea-level fluctuations, and systems tracts through the integration of
seismic and biostratigraphic data. The result is a coherent 3D sequence
stratigraphic framework model with a visual overlay displaying the distribution
of reservoir facies and related sealing formations.
