摘要： An example instrumented formation tester for injecting fluids and monitoring of fluids described herein includes a downhole tool which can be deployed in a wellbore via a wireline or a drill string. The downhole tool may facilitate the injection of fluids into an underground formation, and the monitoring of the directions in which the injected fluids flow in the formation in an open hole environment. In particular, the downhole tool may be configured for removing the mud cake from a portion of the wellbore wall for facilitating a fluid communication with the formation to be tested.

摘要： A technique involves collecting formation fluids through a single packer having at least one drain located within the single packer. The single packer is designed with an outer structural layer that expands across an expansion zone to facilitate creation of a seal with a surrounding wellbore wall. An inflatable bladder can be used within the outer structural layer to cause expansion, and a seal can be disposed for cooperation with the outer structural layer to facilitate sealing engagement with the surrounding wellbore wall. One or more drain features are used to improve the sampling process and/or to facilitate flow through the drain over the life of the single packer.

摘要： A method for analyzing formation fluid in earth formation surrounding a borehole includes storing analytical reagent in a reagent container in a fluids analyzer in a formation tester and moving the formation tester, including the reagent, downhole. Reagent from the reagent container is injected into formation fluid in the flow-line to make a mixture of formation fluid and reagent. The mixture is moved through a spectral analyzer cell in the fluids analyzer to produce a time-series of optical density measurements at a plurality of wavelengths. A characteristic of formation fluid is determined by spectral analysis of the time-series of optical density measurements.

摘要： A flow control valve includes a body having a fluid passageway therethrough and first and second openings each adapted for receiving or discharging fluid from the passageway. A piston is slidably disposed in the passageway between the first and second openings of the body. The piston has a conduit portion that defines a bore therethrough for conducting fluid through a portion of the passageway. The bore has a reduced flow area. A plug is carried within the body and is equipped with one or more annular seals for sealably engaging the reduced flow area of piston bore so as to close the bore upon translatory movement of the piston, the plug, or a combination thereof. The flow control valve has particular application in downhole tools for communicating fluid into, out of, or through the downhole tool when disposed in a subsurface borehole.
