Lithology
Soft-to-medium shale and sandstone
Section
26 in
High-risk interval
0 to 755 ft [0 to 230 m]
Drilling type
Extended reach
An operator needed to drill one remaining extended-reach well on a 32-well pad. However, drilling would pose a high risk of collision with the other wells because of its location at the center of the deck. The previously drilled wells were also in production under high-pressure conditions, so a collision could result in a serious HSE concern. To optimize drilling in the high-risk interval of the remaining well, Schlumberger designed a custom BHA.
