Adjustable Testing Tool and Method of Use

a testing tool and adjustment technology, applied in the direction of survey, wellbore/well accessories, sealing/packing, etc., can solve the problems of contaminating the formation fluid entering the tool, difficult to remove all of the wellbore fluid, and the methods applicable for reducing the contamination of fluids and other debris are not always applicable to reduce the contamination of fluids and other debris

Problems solved by technology

In some situations, a problem occurs when fluid is drawn into the tool through openings along the tool body.
Moreover, when the density of the wellbore fluid is larger than the density of the formation fluid, it is very difficult to remove all of the wellbore fluid since there will be a residual of wellbore fluid that resides between the lowest opening and the lowest packer, even after a log pumping time.
Thus, these wellbore fluids can contaminate the formation fluid entering the tool.
Note that methods applicable for reducing the contamination by mud filtrate surrounding the wellbore are not always applicable for reducing the contamination by fluids and other debris from the wellbore.

Embodiment Construction

[0028]Certain examples are shown in the above identified figures and described in detail below. In describing these examples, like or identical reference numbers are used to identify common or similar elements. The figures are not necessarily to scale and certain features and certain view of the figures may be shown exaggerated in scale or in schematic for clarity and / or conciseness.

[0029]FIG. 2 shows one embodiment of a testing tool capable of sealing wellbore intervals of various lengths. The testing tool 10 is conveyed within wellbore 11 created in formation 12 via conveyance mean 13. The testing tool 10 can be conveyed downhole using a wireline cable after the well has been drilled and the drill string removed from the wellbore. Alternatively, the testing tool can be conveyed downhole on the drill string used to drill the wellbore. Any conveyance mean known in the art can be used to convey the tool 10. Optionally, the conveyance mean allows for two ways communication between too...

Abstract

Methods and systems for testing a subterranean formation penetrated by a wellbore are provided. A testing tool has a plurality of packers spaced apart along the axis of the tool, and at least a testing port. The testing tool is positioned into the wellbore and packers are extended into sealing engagement with the wellbore wall, sealing thereby an interval of the wellbore. In some embodiments, the wellbore interval sealed between two packers is adjusted downhole. In one embodiment, the location of the testing port is adjusted between two packers. The methods may be used to advantage for reducing the contamination of the formation fluid by fluids or debris in the wellbore.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a non-provisional application of co-pending provisional application No. 60 / 845,332 filed on Sep. 18, 2006, and relates to co-pending and commonly assigned U.S. patent application Ser. No. 11 / 562,908 filed Nov. 22, 2006; U.S. patent application No. 60 / 882,701 filed Dec. 29,2006; and U.S. patent application No. 60 / 882359 filed Dec. 28, 2006, the disclosures of which are hereby incorporated herein by reference for all purposes.TECHNICAL FIELD[0002]The present invention relates to well testing tools and method of use. More particularly, the invention relates to testing tools having a plurality of packer elements and at least a testing port on the tool body.BACKGROUND OF THE INVENTION[0003]Advanced formation testing tools have been used for example to capture fluid samples from subsurface earth formations. The fluid samples could be gas, liquid hydrocarbons or formation water. Formation testing tools are typically eq...
