A method for surveying a borehole is provided. The method includes providing a tool having a magnetic field measurement device disposed thereon and positioning the tool in a borehole. Magnetic interference vectors are determined at at least two positions in the borehole by comparing the measured magnetic fields at those positions with a known magnetic field of the earth. The magnetic interference vectors indicate a direction to a target subterranean structure. Various embodiments of the invention compare the directions to the target subterranean structure with a historical survey thereof, so as to determine a distance between the borehole and the subterranean structure and an azimuth of the borehole. The surveying methodology of this invention may advantageously improve borehole surveying data obtained, for example, in relief well and/or well twinning drilling applications.

Internet makes large-sample web surveys easy and inexpensive. However, the survey non-response rate (or missing response) is generally high. It is reasonably expected that the survey non-response rate increases as the number of survey questions increases. We propose a partial survey method, in which only a subset of survey questions are distributed to each tester and different testers may receive different questions. Then, the tester can spend much less time responding a short survey compared to the full survey (which includes all survey questions), and therefore it is less likely for a tester to decline the survey and hence increases survey response rate. A mixed survey, composed of the partial survey and full survey, is as well as an extrapolation estimator were also proposed and studied. Simulation was conducted and showed the partial survey produces less biased estimator for the mean response and regression coefficients than the full survey, but with increased standard error for the estimation. The partial survey provides much less mean squared error for the mean response compared to the full survey.
