Abstract:
Provided are systems and methods for drilling a horizontally-oriented well having a sigmoid-shaped wellbore including an upper sigmoid portion having a downward curving wellbore trajectory and a lower sigmoid portion having an upward curving wellbore trajectory. The upper sigmoid portion having a first trajectory having a generally horizontal gradient at an entry point of the wellbore and that increases in downward gradient to a vertical gradient at an inflection point. The lower sigmoid portion having a second trajectory that includes the vertical gradient at the inflection point and that decreases in downward gradient to a generally horizontal gradient at a horizontal transition point of the wellbore.

Claim (Index 1):
A hydrocarbon well drilling system comprising:\n a wellhead system comprising a wellhead body disposed at a surface of the earth, the wellhead body comprising a wellhead passage configured to guide a drill string from a horizontal orientation to a downward sloping orientation of a wellbore having a sigmoid well trajectory, the wellhead passage extending from a wellhead entrance at a vertically oriented side of the wellhead body to a wellhead exit at a horizontally oriented underside of the wellhead body; a drill string configured to pass through the wellhead passage, the drill string comprising a horizontally oriented starting end and a drill bit configured to bore through a subsurface formation to create the wellbore having the sigmoid well trajectory, the wellbore comprising:\n a first sigmoid portion extending from the wellhead exit to an inflection point of the wellbore, the inflection point being located downhole from the wellhead exit, the first sigmoid portion of the wellbore comprising a first trajectory that is generally horizontal at the wellhead exit of the wellbore and that increases in slope to a first gradient at the inflection point; and \n a second sigmoid portion extending from the inflection point of the wellbore to a transition point of the wellbore, the transition point being located downhole from the inflection point, the second sigmoid portion of the wellbore comprising a second trajectory that matches the first gradient of the first sigmoid portion of the wellbore at the inflection point and that decreases in slope to a second gradient at the transition point; and \n a drilling control system, comprising:\n a motive system configured to exert a horizontal motive force on the horizontally oriented starting end of the drill string to generate a force to facilitate the drill bit boring through the subsurface formation to create the wellbore having the sigmoid well trajectory.
