摘要： The invention relates to a self-tracking sensor mechanism for use with a smart pipeline inspection gauge, commonly termed a “smart pig”. The self-tracking sensor mechanism has a link pivotally attached to a body portion of the pig and a spring for urging the link in a direction away from the body portion of the pig and toward the wall of the pipeline being inspected. A trailing arm is pivotally connected to the link. The trailing arm has a sensor that is maintained in contact with the pipeline interior surface to be inspected during travel of the pig through the pipeline.

摘要： An apparatus and method for obtaining samples of pristine formation or; formation fluid, using a work string designed for performing other downhole work such as drilling, workover operations, or re-entry operations. An extendable element extends against the formation wall to obtain the pristine formation or fluid sample. The apparatus includes at least one extendable gripper element for anchoring the apparatus during testing and sampling operations.
