Abstract
A method for surveying a wellbore includes rotating a downhole tool having a tilted survey sensor in the wellbore. The tilted survey sensor has a sensory axis that is rotationally offset from a longitudinal axis of the downhole tool and is used to make sensor measurements while rotating the downhole tool in the wellbore. The sensor measurements are fit with a sinusoidal fitting function to obtain first and second fitting parameters. A wellbore survey parameter such as wellbore inclination or wellbore azimuth is computed from the first and second fitting parameters.
