  • Downhole build-up pressure test using coiled tubing
    Patent number: 6116340
    Abstract: A method and an apparatus for carrying out a downhole shut-in, pressure build-up test of a formation by lowering a string of coiled tubing having a pressure sensor and a packer thereon through the production tubing of the well. The packer is set to isolated the formation and the pressure is then measured by the pressure sensor.
