    摘要： An apparatus and method useful for acquiring information from a subsurface formation penetrated by a wellbore contemplate the use of a tubular body adapted for connection within a drill string disposed in the wellbore. The tubular body is equipped with one or more protuberances (e.g., ribs) defining an expanded axial portion. A probe is carried by the tubular body at or near a first location within the expanded axial portion of the body where the cross-sectional area of the expanded axial portion is a minimum. The probe is movable between retracted and extended positions. In another aspect, the inventive apparatus may further include a cover releasably-secured about the probe for protecting the probe while drilling. In a further aspect, the inventive apparatus may include a shearable backup support carried by the tubular body azimuthally opposite the probe permitting release of the apparatus from the wellbore in the event of a failure. In yet another aspect, the probe is at least partially carried within a debris-clearing channel formed in a protruding portion of the tubular body to promote free movement of the probe within the wellbore.

    摘要： An apparatus and method for determining at least one downhole formation property is disclosed. The apparatus includes a pretest piston positionable in fluid communication with the formation, and a series of flowlines pressure gauges, and valves configured to selectively draw into the apparatus for measurement of one of formation fluid and mud. The method includes performing a first pretest to determine an estimated formation parameter; using the first pretest to design a second pretest and generate refined formation parameters whereby formation properties may be estimated.
