A structural and stratigraphic
study the Helis East Black Bay Field (offshore
The paper describes the methodology used
in the study. Structural dip values were determined from the shales using dips from microresistivity
images. Paleocurrent flow direction,
and energy of deposition was determined by integrating water based mud microresistivity images and structurally deleted dips (stratigraphic dips). The complete interpretation was
accomplished using static and dynamic borehole images in conjunction with the stratigraphic dips to determine the depositional history.
Deposition was quite active and variable
within the section of interest: Middle to upper-Middle Miocene, the section
containing a number of transgressive and regressive
cycles. Additionally, observations are correlated to published sequence stratigraphy of the Middle Miocene.
The paper concludes with recommendations
from image and dip interpretations of paleocurrents
combined with seismic amplitudes.
