System and method for detecting pressure disturbances in a formation while performing an operation
First Claim
1. A method for detecting pressure disturbances in a formation accessible by a borehole while performing an operation, the method comprising:
- positioning a tool within the borehole;
positioning a first probe of the tool at a first location;
positioning a second probe of the tool at a second location remote from the first location to obtain a pressure reading;
performing an operation with the first probe;
detecting the presence of a single phase fluid within the tool;
detecting a pressure disturbance within the formation with the second probe; and
identifying a second phase fluid based on the detection of the pressure disturbance.

Abstract
A method for detecting pressure disturbances in a formation accessible by a borehole while performing an operation is disclosed. The method includes positioning a tool within the borehole, positioning a first probe of the tool at a first location, positioning a second probe of the tool at a second location remote from the first location to obtain a pressure reading, performing an operation with the first probe, detecting the presence of a single phase fluid within the tool, detecting a pressure disturbance within the formation with the second probe, and identifying a second phase fluid based on the detection of the pressure disturbance. Other methods and systems for detecting pressure disturbances in the formation are further disclosed.

12. A system for detecting pressure disturbances in a formation accessible by a borehole, the system comprising:
-
a tool including;
a housing;
a first probe coupled to the housing at a first position, the first probe being adapted to perform an operation; and
a second probe coupled to the housing at a second position remote from the first probe, the second probe being adapted to obtain a pressure reading;
a wire coupled to the housing of the tool, to support the tool in the borehole;
a controller, coupled to the first probe and the second probe, configured to control an operation with the first probe to analyze a first phase fluid, the controller further being configured to control detection of a pressure disturbance within the formation with the second probe, and configured to analyze whether a second phase fluid may be present based on the detection of the pressure disturbance. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of analyzing pressure disturbances of a fluid within a formation through a borehole, the method comprising:
-
analyzing a first phase of fluid acquired from a formation with a first probe at a first location within the borehole;
detecting pressure changes within the formation with a second probe at a second location, different than the first location, within the borehole; and
identifying whether the fluid within the formation has a second phase based on the pressure changes detected by the second probe. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A system of analyzing pressure disturbances of a fluid in a formation through a borehole, the system comprising:
a controller configured to receive data from a first probe located within the borehole and to analyze a first phase fluid sampled by the first probe, the controller being further configured to receive data from a second probe, spaced from the first probe within the borehole, to determine whether the fluid in the formation has a second phase based on any pressure changes detected by the second probe. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43)
