Problems solved by technology

As DTS spatially averages temperature over approximately 1 meter lengths it fails to provide precise measurements of the inflow temperature of produced fluids.
However, this type of logging tool has had issues with mechanical effectiveness.
Another disadvantage, which increases logging time on the well, is that calibration must be done downhole by making several extra logging runs at various logging speeds.

Embodiment Construction

[0013]Reference will now be made in detail to embodiments of the present invention, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation of the invention, not as a limitation of the invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used in another embodiment to yield a still further embodiment. Thus, it is intended that the present invention cover such modifications and variations that come within the scope of the appended claims and their equivalents.

[0014]As previously discussed, capturing the upstream, downstream and inflow temperatures of produced fluids around the inflow mixing point provides a significant amount of data necessary to determine inflowing produced fluid rates so far as...

Abstract

A matrix production logging tool for measuring the temperature of produced fluids in a wellbore. Accurate production allocation to the pathways between the oil / gas well and the reservoir provides required data for the economic optimization of the techniques and procedures used to complete future wells. The low maintenance tool provides precise upstream, downstream and inflow temperature measurements of produced fluids within the wellbore.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a non-provisional application which claims benefit under 35 USC §119(e) to U.S. Provisional Application Ser. No. 62 / 021441 filed Jul. 7, 2014, entitled “MATRIX TEMPERATURE PRODUCTION LOGGING TOOL,” which is incorporated herein in its entirety.FIELD OF THE INVENTION[0002]This invention relates to a matrix production logging tool for measuring the temperature of produced fluids in a wellbore.BACKGROUND OF THE INVENTION[0003]Well logging surveys are often utilized in producing oil and gas wells in order to determine the fraction of oil, gas and unwanted water present in the production interval. This data along with measurements of the fluid flow velocity, cross-section of the well, pressure and temperature may be used to determine production rates and other information from each zone of interest in the well. Such data may be useful for optimizing the well's production, oil recovery, and water shut-off, in order to achieve...
