    摘要: A method and an apparatus for nucleating bubbles in an oil-gas mixture, including introducing a sample comprising an oil-gas mixture into a chamber; and heating the sample with a heater until at least one bubble is thermally nucleated in the chamber. The bubble point (BP) pressure of the sample can be determined by detecting pressure at two points in a system, which includes the chamber and the heater, and by determining the behavior of the nucleated bubble as the pressure on the bubble is varied.

    摘要: The present invention recited a method and apparatus for measuring a parameter of a fluid within a fluid channel using a tracer element injection by an injection element and detected by a detection element at a location separate from the injection element location. The injection element and detection element of the present invention are in communication with a computational element, wherein the computation element is capable of measuring a parameter of a fluid in a fluid channel based upon time of flight data derived from the injection element and the detection element.

    摘要: The present disclosure relates to one or more apparatuses and methods to determine fluid movement within a formation. The apparatus includes a first packer configured to selectively engage a wall of a borehole of the formation, an outlet disposed adjacent to the first packer, wherein the outlet is configured to pump a first fluid therefrom and into the formation, and a detecting tool configured to detect the first fluid within the formation. Movement of the first fluid may be determined based upon the detection of the first fluid within the formation.
