Abstract

As technology advances, horizontal wells are becoming more common. However, placing the wellbore for more common. However, placing the wellbore for maximum exposure to the pay zone is rarely maximum exposure to the pay zone is rarely straightforward. Petrophysical evaluation of the straightforward. Petrophysical evaluation of the formations also remains challenging due to hole formations also remains challenging due to hole conditions, rig time constraints, BHA design limitations, conditions, rig time constraints, BHA design limitations, and high flow rate requirements. Several recent Logging and high flow rate requirements. Several recent Logging While Drilling (LWD) developments help meet this While Drilling (LWD) developments help meet this challenge.
