Abstract

A system and method for drilling a substantially horizontal well bore 44 in a normally to sub-normally pressured formation 30. The normally to sub-normally pressured formation is an unconventional reservoir 30. The well bore is drilled over-balanced with a drilling fluid having a density at least about the density of the cuttings produced by drilling the well bore.
