Summary Measurements of shear-wave splitting in microseismic data are used to study seismic anisotropy in an oilfield in west-central Oman. Over 460 events are recorded by up to 10 downhole seismometers deployed in 5 boreholes resulting in nearly 2500 shear-wave splitting measurements. Stringent quality control reduces the number of reliable measurements to
