The use of titania polymorphs as indicators of hydrocarbon migration in sedimentary basins
May 20, 2021
The main goal of this project is to determine if diagenetic titania polymorphs can be used as a tool in tracking hydrocarbon migration in sedimentary basins. Titania (TiO2) occurs as three main polymorphs. Rutile is mostly pedogenic; anatase is prominent during eodiagenesis, particularly in lowstand systems tracts; and brookite is predominantly late mesodiagenetic. Ti, similar to V and Fe, can be readily mobilized when hydrocarbon-rich fluids are generated in sediments. Gas reservoirs in the Scotian Basin have common brookite, whereas the water intervals of reservoirs have anatase.

Identification and Ranking of Seabed Seep Prospects on the Scotian Slope
January 21, 2021
Studies have shown that seafloor seepage of thermogenic hydrocarbons can been linked to the presence of an active petroleum system. Nova Scotia has been researching, surveying, and piston coring potential offshore hydrocarbon seeps along the deep-water Scotian Slope since 2015. It is the hope that by confirming the presence of hydrocarbons naturally leaking from source rocks or reservoirs in our deep-water, it can encourage exploration offshore Nova Scotia. But what do these seeps mean? And how do we identify potential seep and coring sites?
