A geosteering geologist collects data and samples to find the optimal placement for oil drilling equipment and an oil well. You can work on land or an offshore oil rig. You collect seismic data and look at structural maps, and you look at samples during and after drilling operations. Your duties include monitoring drilling in real-time and providing input into the direction of the borehole. You communicate with other geologists and with the drilling team. Your responsibilities usually include using measurement while drilling (MWD) tools to map the drilling and show the drilling team how to steer the drill.
