Abstract:
Understanding the uniaxial compression behavior of soil is important to engineers in the
offshore oil and gas industry. Laboratory compression test data is a key parameter to
characterizing overpressure zones underground. This research investigates two parameters
related to one-dimensional compression behavior through a rigorous laboratory
experimental program. First, the effect of ... read moretemperature on compression behavior is
examined using data from ten constant rate of strain tests. Five elevated temperature
tests are compared to five room temperature tests in the stress range of 0.1 to 40 MPa
to conclude that temperature does not have an effect on compression behavior.
Additionally, there is an investigation of how the pore fluid salinity of a specimen
changes with compression. The results of twenty-one salinity tests indicate that
salinity decreases with compression. Following the experimental program a model is
developed to predict the salinity at a given stress level and compared to the collected
data.
