HORIZONTAL SIDETRACK TAPS RESERVOIR "SWEET SPOTS"

James R. Wible Aran Energy Corp. Houston Cutting a window at 850 deviation allowed a sidetrack to pass through the high-resistivity sections in a Gulf of Mexico reservoir. Results from logging-while drilling (LWD) tools indicated the original horizontal bore dropped too low in the reservoir, possibly leading to a low productivity well. The subsequent sidetrack successfully delivered the desired well bore, and the increased productivity justified the efforts in cutting a window in the horizontal
