WebApr 2, 2011 · The real-time checkshot data were used to update the pre-drill velocity model as drilling progressed. Drilling interval for both wells was approximately 800 m (2,625 ft), and checkshots were acquired every … WebMar 27, 2024 · The delta curves will be used to build 3D delta models (see Delta Model) for anisotropic depth migration. In general, delta is calculated at the wells using the checkshot Vint and an initial (NMO) isotropic Vint field. There is an option to use the small delta approximation for this calculation if you want. hiro platform

WebBorehole seismic services offer high-resolution data that enable 3D images. This improves vertical and lateral reservoir resolution compared with surface seismic data. Our digital data acquisition services reduce rig time and improve your production while reducing well and field development risk. Contact your Baker Hughes representative to ... WebJan 29, 2024 · The checkshot survey is a measurement of seismic travel time at a range of depths in the borehole, at least at key stratigraphic boundaries and total depth. … WebThe drift curves are used to adjust the sonic logs. On the drift curves, the slope of the segment of the straight line joining two consecutive knees is the gradient of the drift, expressed in microseconds/ft is the average drift, i.e. correction to be applied to the sonic transit time.! When slope is negative, drift is said to be negative, which hiro plastic
