Patent number: 9051823Abstract: Fluid flow measurement device and method. In one embodiment, a tool comprises a rotating arm with a sensor pad to measure fluid flow into or out of the casing wall. The arm maintains the sensor pad in close proximity to the casing inner wall. The tool diameter is variable to allow the tool to traverse variable diameter casings and pass obstacles. The sensor pad comprises flow channels to direct the flow of fluid by electromagnetic sensors configured to detect conductive fluid flow.Type: GrantFiled: October 18, 2013Date of Patent: June 9, 2015Assignee: REM Scientific Enterprises, Inc.Inventors: Robert E. Maute, Feroze J. Sidhwa

Publication number: 20150052738Abstract: Methods of manufacturing a logging tool for a borehole are provided. In an embodiment of the present invention, shields are disposed to prevent or reduce circulating electrical currents from causing a voltage difference that would adversely affect the measured voltage difference between two adjacent electrodes. Groups of sensors, e.g., two or more, may be placed within the shield. The shields may have any cross-section shape. A magnetic field source is disposed proximate the electrodes such that the magnetic field source is oriented to generate a magnetic field substantially orthogonal to an imaginary line intersecting each pair of electrodes. A voltage measuring circuit is electrically coupled to the plurality of electrodes and configured to measure a voltage difference between each pair of electrodes.Type: ApplicationFiled: November 3, 2014Publication date: February 26, 2015Applicant: REM SCIENTIFIC ENTERPRISES, INC.Inventor: Robert E. Maute

Patent number: 8763451Abstract: In a borehole logging tool, the flow of conductive fluid into or out of a wellbore at the wellbore wall is detected and measured with a sensor loop proximate the borehole inner wall. The sensor loop includes a series of contiguous sensors that act as electromagnetic flowmeters and provide fluid measurements covering the entire circumference of the sensor loop. The sensor loop includes an elastic element that forces the sensor loop outward to maintain pressure along the sensor loop circumference against the interior borehole wall. The sensor loop is designed to lie at a non-perpendicular angle to the wellbore axis, and mechanical arms press the top and bottom of the loop against the borehole inner wall.Type: GrantFiled: July 30, 2012Date of Patent: July 1, 2014Assignee: REM Scientific Enterprises, Inc.Inventor: Robert E.

Patent number: 8312767Abstract: Methods and apparatuses for detecting radial flows of conductive fluid are provided. In an embodiment of the present invention, shields are used to prevent or reduce circulating electrical currents from causing a voltage difference that would adversely affect the measured voltage difference between two adjacent electrodes. The shields may be a conduit through which conductive fluid may flow. Groups of sensors, e.g., two or more, may be placed within the shield. The shields may have any cross-section shape. Generally, once the circulating electrical current flow between the electrode pairs is substantially reduced or eliminated, only the voltage difference from the localized induced electric field remains. This way, a true induced voltage may be measured, and thus an accurate value for the fluid velocity may be determined.Type: GrantFiled: January 10, 2011Date of Patent: November 20, 2012Assignee: REM Scientific Enterprises, Inc.Inventor: Robert E.
