...:2021 ). Often these hydrocarbon intervals cannot be predicted resulting in cautiously setting the HWPH and conductor at nonoptimal, from a well design point of view, shallow depths. This creates a "top-down" well design. This may result in the final casing diameter being as small as 5 in. Due...
