Method and system for subsurface logging utilizing a modified tubular having
an elongated body with tubular walls and a central bore adapted to receive a support
member. The tubular including slotted stations to provide through-tubular signal
passage. Pressure barrier means provide hydraulic isolation at the slotted stations.
The support member is equipped with sources or sensors and adapted for engagement
within the tubular. The tubular and support member are implemented in combination
with retrievable and re-seatable MWD apparatus.
