  • Systems and methods for measuring forces acting on a downhole tool
    Patent number: 9038452
    Abstract: An apparatus for measuring forces acting on a downhole tool is provided. The apparatus can include an annular body having an axial bore formed therethrough. A first fluid can be disposed within the bore. An annular sleeve can be disposed proximate an inner surface of the body. An annular chamber can be formed between the body and the sleeve, and a second fluid can be disposed within the chamber. A sensor can be coupled to the sleeve to measure a strain placed on the sleeve by a pressure differential between the first and second fluids. A pressure of the first fluid in the bore can be determined from the strain.
