Interpretation of stratigraphic-stacking patterns
on the Santa Margarita seismic line
The process of sequence stratigraphy interpretation involves the identification of erosional and depositional surfaces in the sedimentary
section. Using seismic these surfaces can be inferred to be present where the seismic reflectors terminate and or exhibit evidence of
truncation against other reflectors.
On the Santa Margarita seismic line below you can identify both termination and truncation and record this on the Power Point image
using the ‘curve’ tool. An initial line is provide you and can be copied and edited to confirm to your interpretations.
For the sake of starting your interpretation you should edit the “curve” line by right clicking on line and holding down the mouse this will
activate a vertical menu. A third of the way down the menu is menu item "Edit Points". Click on this and on the line formed by the curve
tool output, black points appear. The shape of the interpretive line can be edited by dragging points on the line. A succession of
interpretive lines will provide a chronostratigraphic framework to a sedimentary section that can be used to determine depositional setting
of the sediments in that section:
The succession of major surfaces subdividing the sedimentary section form a template for the conceptual depositional models you
believe are responsible for the Santa Margarita sedimentary section. The sequence stratigraphic framework outlines the geometric
hierarchy of sedimentary strata and elements formed by the strata. These can then be used to predict:
• Play geometries and character
• Reservoir geometry and character
