 Fluid Inclusion microthermometry measurements can provide quantitative numerical estimates of the temperatures at which mineral cements were precipitated during diagenesis. For hydrocarbon-filled inclusions, properties such as API gravity and GOR can be estimated in addition to trapping temperature. For aqueous inclusions, the salinity of the water can be measured.
At Panterra we conduct fluid inclusion petrography based on the Fluid Inclusion Assemblage (FIA) approach. A Fluid Inclusion Assemblage is a group of petrographically associated fluid inclusions that formed at about the same time or during the same set of diagenetic conditions. Primary inclusions (trapped during cement growth) are thus carefully distinguished from secondary inclusions (trapped along fractures formed after cement growth). |
