Abstract: A method of formation fluid sampling that includes setting a dual packer tool in a wellbore. The dual packer tool is used to isolate an interval between an upper packer and a lower packer. The method also includes drawing fluid from the interval with a lower inlet, until an oil fraction increases over a base line reading, and drawing oil from by pumping at a low rate with an upper inlet.

Abstract: A multi-contact electrical connector assembly includes a first connector housing to electrically couple to a second connector housing. A moveable piston is disposed in a bore of the first housing and is biased to be adjacent a first plurality of electrical contacts on a surface of the bore. An end of the first housing has a first pressure connector electrically coupled to the first plurality of electrical contacts. A moveable annular piston is disposed about a rod in a bore of the second connector housing and is biased to isolate a second plurality of electrical contacts on an outer surface of the rod. The second housing also has a pressure connector electrically coupled to the second plurality of electrical contacts. The moveable piston and the moveable annular piston are simultaneously moveable to expose and matingly engage the electrical contacts.
