Task 1: (1.5 Marks)
What are the processes that are responsible for the marine transgression and regression?
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.
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.
Task 3: (1.25 Marks)
Match the following typical deposition with the corresponding basin name. The correspondence is one-

Task 5: (2 Marks)
Draw a correlation for the three geologic sequences shown in the three locations in Figure 1 using the
fossils to establish the relative age for each sequence.
Outcrops at three different locations
Task 6: (2.5 Marks)
In the geologic sequence shown in Figure 1 establish the right time sequence of the five formations,
from the oldest to the youngest.
Task 7: (2.5 Marks)
The coefficient of variation for permeability for several core plugs from different rock
formations are as follows:
Degree of heterogeneity
Homogeneous Heterogeneous Highly
(a) In the table above, specify the degree of heterogeneity for each rock type by a (x) sign in
front of the correct choice.
(b) Explain why you have selected the choices for the previous part.
