Benefits of technology

[0007]The present invention disclosed herein provides a system and method for evaluating reservoir fluids from multiple zones in a single trip. In addition, the system and method of the present invention reduce the time spent unloading fluid lost into the formations during the drilling and cementing phases of well construction.

Problems solved by technology

Accordingly, use of such sampling techniques can be quite time consuming in wellbores having multiple zones.
In addition, it has been found that fluid loss into certain formations occurs during the drilling, cementing and completions phases of well construction.
This swabbing process may take hours for each zone causing days of delay in wells having multiple zones.

Embodiment Construction

[0023]While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts which can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.

[0024]Referring initially to FIG. 1, therein is representatively illustrated a formation fluid evaluation system that is generally designated 100 and which embodies principles of the present invention. Formation fluid evaluation system 100 is disposed within a wellbore 102 that includes casing 104. Wellbore 102 traverses various earth strata including a plurality of zones of interest such as zones 106, 108, 110 which may be portions of a common formation or reservoir, or one or more of the zones may be portions of separate formations or reservoirs. As illustrat...

Abstract

A formation fluid evaluation system (800) interconnected within a tubular string (818) for operation in a wellbore (802) having multiple zones (806, 808, 810). The evaluation system (800) includes a set of straddle packers (820, 822) that is operable to sequentially isolate the multiple zones (806, 808, 810). A test valve (824) is disposed between the straddle packers (820, 822). A fluid unloading assembly (828) is positioned uphole of the straddle packers (820, 822). The fluid unloading assembly (828) is operable to draw fluid (834) from the isolated zone (808) into the tubular string (818) through the test valve (824) in response to the circulation of a drive fluid down the tubular string (818). A formation evaluation instrument (836) is disposed within the tubular string (818) and determines a characteristic of the fluid (834) received from the isolated zone (808).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a continuation-in-part application of co-pending application Ser. No. 11 / 811,761 filed on Jun. 11, 2007.TECHNICAL FIELD OF THE INVENTION[0002]The present invention relates, in general, to testing and evaluation of subterranean formation fluids and, in particular, to a single trip, multi-zone formation fluid evaluation system and method for unloading fluids from each zone prior to evaluating reservoir fluids at reservoir conditions.BACKGROUND OF THE INVENTION[0003]Without limiting the scope of the present invention, its background is described with reference to testing hydrocarbon formations, as an example.[0004]It is well known in the subterranean well drilling and completion art to perform tests on formations intersected by a wellbore. Such tests are typically performed in order to determine geological or other physical properties of the formations and the fluids contained therein. For example, parameters such as permeability, po...
