Oilfield Wastewater Density

2019 STUDENT AWARDS

Richard S. Jayne (PhD 2019) and Assistant Professor Ryan Pollyea and their research team from the Department of Geosciences published a study in July 2019 showing that fluid composition plays an important role in the occurrence of injection-induced earthquakes. This study finds oilfield wastewater in Oklahoma and Kansas has a much higher density than fluids in the seismogenic zone. When injected into deep geologic formations, wastewater sinks and increases fluid pressure to levels sufficient to induce

earthquakes. By comparing numerical groundwater models of high density wastewater injections with the earthquake record in Oklahoma and Kansas, the researchers discovered that average earthquake depth increases at same rate as high-density wastewater sinks. They also found that the relative proportion of high-magnitude earthquakes increases with depth, which means that the injection-induced earthquake hazard in Oklahoma and Kansas may persist much longer than previously thought.
