Abstract
Nukhul Formation contains biodegraded heavy oil at Lagia Field, and
consists of five sandstone lobes that are interbedded with mudstones. All lobes
deeper than the first lobe have been truncated up dip or faulted out and are not
present. The sandstones are typically fine to medium grained and well
cemented with calcareous cement.
The structural contour map shown in Figure 2 displays TWTT contours,
drawn at the top of the Nukhul Formation. Reservoirs penetrated by Lagia 3, 5,
6 and 7 wells are bounded on the east and south by faults that are assumed to
be sealing. An oil column overlain by gas and underlain by water is assumed to
extend along strike from the fault on the south until it is cut by the northwest
trending fault. The structural dip within this area is about 7.5 degrees to the
southwest.
We will explain the distribution of petrophysical parameters (shale,
porosity, water saturation ,hydrocarbon saturation) of Lagia field through
isoparametric maps .
The shale distribution map illustrate the horizontal distribution of shale
in the study area it show that, the shale has minimum value at south direction
of the map where maximum value is represented in north east directions.
The total porosity distribution map reveals a gradual increase toward
south direction of the map where maximum value in Lagia-7. While it
decreases to west direction.
