42. A method for taking downhole samples, comprising:
-
establishing fluid communication between a flowline in a downhole tool and a formation by extending the a packer seal to be in contact with a formation; obtaining a core sample using a coring bit configured to extend inside a sealing area of the packer seal; ejecting the core from the coring bit and into a sample chamber; and withdrawing a formation fluid from the formation through the flowline. - View Dependent Claims (43)
