Abstract
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.
