A Type II profile $($build$,$ hold and drop$)$ is planned for the following

well: VI $=10,000$ ft$,$ HI $=4000$ ft$,$ build up and drop$-$off rate $=2\backslash$deg

per $100$ ft$.$ At the end of the drop$-$off section the inclination is to be $0\backslash$deg

at a TVD of $9000$ ft$.$ If the inclination over the tangential section is

not to exceed $50\backslash$deg $,$ what is the deepest kick $-$off point that will meet the

requirements of the well?
