摘要： A formation fluid sampling tool is provided with a drill which drills into the formation in a manner perpendicular or oblique to the borehole wall. Preferably the tool introduces a mechanism into the drilled hole for enhancing the mobility of the reservoir fluid. In one embodiment the mechanism is a heating element on the drill. In another embodiment, the mechanism is hot fluid which is generated in the tool and injected into the drilled hole. In another embodiment, the mechanism is a solvent which is stored in the tool and injected by the tool into the drilled hole.

摘要： Methods and apparatus for the characterization of formation fluids are disclosed. A downhole tool disposed in a borehole penetrating a subterranean formation obtains a NMR measurement, effects a change in a characteristic of the formation fluid, and obtains another NMR measurement subsequent to the change. Alternatively, the downhole tool effects a radial gradient of a characteristic of the formation and obtains NMR measurements at two or more selected radial distances from the wellbore wall. A parameter representative of the subterranean formation or the formation fluid is further determined from the NMR measurements.

摘要： A system and method for determining the asphaltene content of a downhole oil sample are provided. In one example, the method includes obtaining a hydrocarbon sample from a hydrocarbon formation of a reservoir at a given depth using a downhole tool. A liquid phase of the hydrocarbon sample is isolated within the downhole tool and the liquid phase is subjected to downhole analysis within the downhole tool to create a chromatography sample. The downhole analysis is based at least partially on size exclusion chromatography. A first property of the chromatography sample is measured to obtain a measured value, and a second property of the chromatography sample is estimated based on the measured value and known calibration curves.
