摘要： Methods and apparatuses for evaluating a fluid from a subterranean formation of a wellsite via a downhole tool positionable in a wellbore penetrating a subterranean formation are provided. The apparatus relates to a downhole tool having a probe with at least two intakes for receiving fluid from the subterranean formation. The downhole tool is configured according to a wellsite set up. The method involves positioning the downhole tool in the wellbore of the wellsite, drawing fluid into the downhole tool via the at least two intakes, monitoring at least one wellsite parameter via at least one sensor of the wellsite and automatically adjusting the wellsite setup based on the wellsite parameters.

摘要： A method of evaluating a fluid from a subterranean formation drawn into a downhole tool positioned in a wellbore penetrating the subterranean formation is provided. The method involves drawing fluid from a formation into an evaluation flowline, drawing fluid from a formation into a cleanup flowline, measuring a property of the fluid in the evaluation flowline and detecting stabilization of the property of the fluid in the evaluation flowline. Fluid properties in a combined flowline may be generated from the evaluation and cleanup flowlines. The fluid properties of the combined flowline may be used to project future evaluation flowline fluid properties. Contamination levels for a given fluid property of a given flowline may also be determined.

摘要： A method for acquiring a sample of a virgin fluid from a subsurface formation penetrated by a wellbore surrounded by a layer of contaminated fluid is disclosed. The method includes abutting a first packer against a wall of the wellbore, and extending at least a portion of a second packer beyond the first packer, wherein the second packer is at least partially disposed in the first packer. An inlet to a first flowline is at least partially defined by the first packer, and an inlet to a second flowline is defined by the second packer. The method further includes drawing one of virgin fluid, contaminated fluid and combinations thereof into the first flowline; and drawing virgin fluid into the second flowline.

摘要： An extendable component for use in a downhole tool for traversing subsurface formations includes a drive element that defines an axis and has a distal end, and an abutment that is spaced radially from a distal end of the drive element. A driven element defines a driven element axis, is flexibly coupled to the drive element, and includes a proximal end disposed adjacent to the drive element and a distal end. A tilt arm is coupled to the driven element, is disposed at an angle with respect to the driven element axis, and is configured to engage the abutment. The driven element is moveable between a normal position and a tilted position. A contact head is coupled to the driven element distal end and is adapted to engage the wellbore wall.
