Abstract EN
Physical properties of gas hydrate-bearing soils are known to be greatly affected by the pore space hydrate saturation.
The accuracy of most saturation estimation methods is affected by hydrate growth habit and pore space distribution.
We highlight the usefulness of dissociation gas evolution measurement (DGEM) method as a reference laboratory method to calibrate most other methods.
The DGEM method is based on the concept of mass balance and properties of volume compatibility between two distinct states of a closed system.
The accuracy of the estimation depends on (1) the precision with which the laboratory measurements of temperature, pressure, and volumetric properties are obtained (2) and the ability of theoretical models used in the calculation to closely represent the true nature of the system.
We perform an analysis to evaluate the sensitivity of the estimation (1) to various laboratory measurements and (2) to the use of different theoretical models to generate a feel for the appropriateness of various assumptions associated with DGEM.
The comprehensive guide to available resources useful in the hydrate saturation estimation also serves as one of the major contributions of the work presented.
