Fracture connectivity and power laws
It was about a year ago that I heard about a deep geothermal drilling project in Finland (St1 Deep Heat Project), during which a couple of 6 km deep wells…
The hidden lithium treasure of South Australia
Despite receiving just 165 mm of rain annually, Coopers Creek flows year-round, an anomaly that has lured generations of explorers in pre-history to early European settlers. Exploration by geologist Reg…
Are deep closed-loop geothermal systems doomed?
“Claims of universal geographical scalability of Closed Loop Geothermal Systems (CLGS) in power generation at competitive prices are not supported by simulation results,” is what the authors conclude in a…

How careful core description and detailed biostratigraphic analysis can delineate sub-seismic reservoir zones in a highly mud-prone system
This study was undertaken by PetroStrat in collaboration with Stratum AS (QEMSCAN), Barnwell Parker Geoscience Limited (seismic interpretation) and HM Research Associates (heavy mineral provenance analysis). Together, we have completed…
Heat flow as a basin model calibration? Not really
Many exploration geologists who work in data-lean basins or who do not have access to well data turn to published heat flow data as a calibration for basin models. More…
Geomodelling for CCS, a bridge too far?
Traditionally, geomodels are built in a simplistic fashion, taking into account the inherent degree of uncertainty in the input data. Attempting to accurately depict an unseen geological object, often multiple…
