摘要: An apparatus and method for obtaining samples of pristine formation or fluid, using a work string designed performing other downhole such as drilling, workover operations, re-entry operations. extendable element extends against the wall to obtain fluid sample. While test tool is in standby condition, withdrawn within string, protected by structure from damage during operation string. The mounted on sliding, non-rotating, sleeve
