MWD/LWD QA Tim Parker, Halliburton, USA be complex, making the logs from conventional gamma-ray sensors confusing and difficult to interpret. The Radian™ azimuthal gamma-ray and inclination service from Halliburton Sperry Drilling provides Geosteering high-quality images of the borehole wall, delivering a In unconventional reservoirs, placing wells and knowing cost-effective solution for geosteering and reservoir their position, while minimising costs, are critical evaluation at temperatures up to 175˚C (347˚F). The components in making a reservoir viable. The natural service provides 360˚ coverage of the borehole in gamma-ray signatures in some of these formations can real time, even while sliding, helping the operator to make better geosteering decisions to maximise reservoir contact. The tool can also be fitted with an inclinometer package, providing continuous, real time inclination measurements, which give immediate feedback on the impact of steering decisions on the well
