Aim: To predict resistivity and gamma ray log responses in different depositional
environments.

Resistivity Response upwell
Gamma-ray response upwell
For each of the above depositional environments, estimate what the log response will be
in a direction going up the well. Complete the table above with:
Increasing electrical resistivity, Decreasing electrical resistivity, Increasing gamma
ray intensity, Decreasing gamma ray intensity
In addition, for each depositional environment, predict the type of grain-size and
compositional change going up the well (if applicable).
Use as much space as needed.
