The Way Ahead Interview - A conversation with Paal Kibsgaard, Schlumberger chief executive officer.

A Novel Approach to Incorporate Full Petroleum System Analysis into Play Risk Assessments

“…A recent survey indicates that, worldwide, an average of two out of three wildcat exploration wells fails to find commercial quantities of hydrocarbons, and 75% of these failures result from incorrect evaluation of charge or seal risk (Kibsgaard, 2011). Clearly, there is a need to improve our assessment of play risk if the industry is to improve its exploration success ratio.…”

Molybdenum Sulfides Materials As Hydrogen Evolution Catalysts and Surface Protecting Layers for Highly Active and Stable Silicon-Based Water Splitting Photocathodes

“…While the stability of this structure is among the best reported for silicon photocathodes, but the low density of HER-active MoS 2 edge sites at the electrode/electrolyte interface limits the voltage generated by this device. As illustrated in the figure below, we incorporate additional molybdenum sulfide HER catalysts such as [Mo 3 S 13 ] 2clusters 12 to increase the density of active site densities and improve the photocurrent onset voltage to within ~150 mV of the best reported Pt/Si photocathodes.…”
