An operator in India experienced a drop in gas production in a high dogleg severity land well in a coalbed methane field. They needed to sidetrack a 6-in. borehole in the complicated well. The planned well was greater than 90° inclination in a narrow coal seam. The goal was to maximize reservoir exposure in the long lateral (2,297 ft/700 m) and boost production. Baker Hughes, a GE Company (BHGE), was engaged to drill the top-hole and sidetrack the well. The BHGE Drilling Services team deployed the BHGE Navi-Drill TM Ultra Xtreme TM and BHGE Ultra Xtreme IR directional drilling motors with the APS Tech Sureshot TM EM directional and gamma measuring-while-drilling (MWD) service to deliver real-time directional information required to drill the 81/2-in. top-hole section a
