<p style="margin: 0px; padding: 10px 0px; border: 0px; outline: 0px; font-family: Arial, Helvetica, sans-serif; color: #333333">It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation.</p><p style="margin: 0px; padding: 10px 0px; border: 0px; outline: 0px; font-family: Arial, Helvetica, sans-serif; color: #333333">Although the most precise method of simulating and calculating a wellbore trajectory generally requires more calculation than other, less-accurate methods, the wider use of computers in oil fields now eliminates this as an obstacle.</p><p style="margin: 0px; padding: 10px 0px; border: 0px; outline: 0px; font-family: Arial, Helvetica, sans-serif; color: #333333">The results of various calculations show that there is a deviation of more than 10 m among the different methods of calculation for a directional well of 3,000 m.<sup style="margin: 0px; padding: 0px; border: 0px; outline: 0px; font-style: inherit; font-size: 12px; font-family: inherit">1</sup> Consequently, it is important to improve the precision and reliability of survey calculation-the fundamental, necessary work of quantitatively monitoring and controlling wellbore trajectories.</p>
