Task 1: (1.5 Marks)
What are the processes that are responsible for the marine transgression and regression?
Assessment Tool
Task 2: (4 Marks)
The matrix in figure below is a set of measurements for water saturations (in % points) at
different locations in a reservoir rock formation. The data are plotted on a regular grid with both
horizontal (x) and vertical (y) distance of 1 between neighbouring points of measurement.
a) Write down the general equation for variogram calculation.

Assessment Tool
b) Calculate the experimental variogram for horizontal (x or 0°), vertical (y or 90°) and for the diagonal (45°) direction for the shortest possible nonzero distance in each case.

Sediments are supplied
from rivers.
Fluvial and lacustrine
sediments.
The clastic sediment
supply is largely
from the adjacent
continental land area.
In the deeper parts
sedimentation is
mainly pelagic,
consisting of fine-
grained biogenic
detritus and clays.
In some places sediments
are carried down the
subduction zone.

fossils to establish the relative age for each sequence.
