摘要: A downhole tool for extracting a sample from a subsurface formation includes an emitter of electromagnetic energy configured to heat water in the subsurface formation. A method for extracting a sample from a subsurface formation involves conveying a downhole tool in a wellbore drilled through the subsurface formation, the downhole tool having an emitter of electromagnetic energy configured to heat water in the subsurface formation, and actuating the emitter to expose a portion of the formation to electromagnetic energy.

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 flexible skin and one or more drains coupled to the outer flexible skin. The single packer further comprises one or more sensors positioned to detect one or more specific parameters that may be related to well characteristics and/or single packer characteristics.

摘要: A method of sampling fluid from a subterranean formation includes positioning a first tool having a heater in a borehole so that the heater is adjacent a portion of the subterranean formation; heating with the heater the portion of the subterranean formation; removing the first tool from the borehole; orienting a second tool having a sampling probe in the borehole so that the sampling probe is to contact a portion of the subterranean formation heated by the heater; and obtaining via the sampling probe a fluid sample from the portion of the subterranean formation heated by the heater.
