ABSTRACT A directional guidance device, for deflecting a drill bit away from the longitudinal axis of a substantially horizontal section of a wellbore, takes advantage of gravitational force to move a deflector member therein between first and second positions. In the first position, the deflector member prevents the drill bit from advancing past the directional guidance device. In the second position, the deflector member allows the bit to pass out of the guidance device, and deflects the bit away from the longitudinal axis of the horizontal section of the wellbore. A method of producing hydrocarbons includes drilling a wellbore including a slanted, substantially straight section, a substantially curved section, and a substantially straight, substantially horizontal section. The slanted section is drilled at an angle of approximately 60° from horizontal and the curved section is drilled at an angular rate of build of approximately 7?° per 100 feet. Multiple offset wells are drilled from the substantially horizontal section at an angle of approximately 30° from the longitudinal axis of the substantially horizontal section.
