Abstract
An apparatus (3) for use when gathering parameters from a well flow in a petroleum well (1) in order to be able to evaluate the flow and productivity or injectivity of the well is described, the apparatus (3) including: —a semi-rigid rod (5) arranged in a manner allowing it to sense the temperature profile of the well (1); —at least two mutually spaced-apart measuring devices and/or fluid phase indicators (9) attached to the semi-rigid rod (5); and —at least one pressure sensor (11) arranged in a manner allowing it to sense pressure in the well (1), whereby the amounts of water, oil and gas from one or more formation sections may be quantified. A method of using the apparatus is also described.
Claims10
An apparatus for use when gathering parameters from a well flow in a petroleum well for allowing evaluation of the flow and productivity or injectivity of the well continuously for a period of time, the apparatus including:
- a continuous, semi-rigid rod arranged in a manner allowing it to sense the temperature profile of the well;
- at least two mutually spaced-apart fluid phase indicators attached to the continuous, semi-rigid rod;
- and
- at least one pressure sensor arranged in a manner allowing it to sense pressure in the well, characterized in that the at least two mutually spaced-apart fluid phase indicators are disposed around the semi-rigid rod, the fluid phase indicators being arranged for detecting and quantifying the velocity and density of the fluid;
- and that each of the mutually spaced-apart fluid phase indicators comprise trace elements and/or chemicals that are arranged in a manner allowing them to be separated from each other, and that the fluid phase indicators are simultaneously affected by the well flow.
