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 23):
The method of  claim 22 , wherein the down-hole portion of the wellhead passage has a first internal diameter, and wherein the hanger section comprises:\n a casing hanger shoulder defined by a casing hanger portion of the up-hole portion of the wellhead passage having a second internal diameter that is greater than the first internal diameter; and a production tubing hanger shoulder defined by a production tubing hanger portion of the up-hole portion of the wellhead passage having a third internal diameter that is greater than the second internal diameter, wherein the production tubing hanger portion is located up-hole from the casing hanger portion.
