Nanoscale imaging of shale fragments with coherent X-ray diffraction
Workflow for Sensitivity Analysis and Decision Making on the Lower Limit of the Mud-Weight Window in an Overpressured Formation
When drilling a well it is important to choose a reasonable mud density to ensure safe operations. This is not a trivial task because a balanced mud-weight has a complex relation to the uncertain formation conditions and properties. The paper presents a method for conducting sensitivity analysis...

Effects of Water Content and Temperature on Bulk Resistivity of Hybrid Cement/Carbon Nanofiber Composites
Micro- and macroscale consequences of interactions between CO2 and shale rocks
In carbon storage activities, and in shale oil and gas extraction (SOGE) with carbon dioxide (CO2) stimulation fluid, CO2 comes into contact with shale rock and its pore fluid. As a reactive fluid, the injected CO2 displays a large potential to modify the shale’s chemical, physical, and...
Simple Simulation of Fracturing as a Result of CO2 Mineral Dissolution and Precipitation
CO2 sequestration in aquifers or depleted oil and gas fields depends on good injectivity, which is not decreasing over time, to achieve the target storage capacity of the chosen reservoir. Depending on the mineral composition of the rock formation into which CO2 is planned to be stored, dissolution...
Tensile strength of cement to shale interface
Permanent CO2 sequestration relies on avoiding leakage from the reservoir through the caprock. The highest leakage risk resides at the wells penetrating the reservoir, in particular at the boundary between cement sheath and formation. Models quantifying the risk of cement debonding require the...
