Title:
DETERMINING GRADIENTS USING A MULTI-PROBED FORMATION TESTER
Document Type and Number:
WIPO Patent Application WO2004099552
Kind Code:
A3
Abstract:
Methods for operating multi-probed formation testers to determine a fluid density gradient in the formation. The probes of the multi-probed formation tester are connected to a pressure gauge through a flowline that establishes a differential height between the probes. In some embodiments, a gradient of the fluid density in the flowline is determined as a function of the gradient of fluid density in the wellbore. The flowline fluid density gradient is then used to determine a formation fluid density gradient as a function of the flowline fluid density gradient.
