Abstract

As the borehole increases from 8 inches to 17 inches, the percentage of borehole area measured with the tool reduces from 80% borehole coverage to 40%. By incorporating a rotating chassis, 100 percent of the borehole can be measured regardless of the borehole size.

Title:  360 Degree Resistivity Measurement with Wire Line tool product line or any such Wire Line like tool

Abstract:  As the borehole increases from 8 inches to 17 inches, the percentage of borehole area measured with the tool reduces from 80% borehole coverage to 40%.  By incorporating a rotating chassis, 100 percent of the borehole can be measured regardless of the borehole size.

Description:  The tool contains six arms each containing up to 10 sensor buttons and 2 transmitter plates.  When a resistivity measurement is to take place, the arms are extended away from the tool chassis to make contact with the borehole formation or casing.  By changing the current chassis stationary design to a design that will rotate the chassis 360 degrees, the entire borehole can be evaluated at one time.

The design would implement a rotatable chassis controlled by an AC/DC motor or stepper motor held in place by isolator arms that would allow the sensor section of the tool to rotate ensuring 360 degree measurement coverage.
