Resumo:
It is now possible to improve the precision of well survey calculations by order of magnitude with numerical approximation.
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.
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.1 Consequently, it is important to improve the precision and reliability of survey calculation-the fundamental, necessary work of quantitatively monitoring and controlling wellbore trajectories.
