Sharewell Transmits Electro-Magnetic MWD Data In Barnett Shale

Sharewell L.P. successfully drilled through the Marble Falls formation in the Barnett Shale in North Texas with its new Electromagnetic Telemetry (EM) MWD. The company’s patented, proprietary EM-MWD system effectively transmitted data on a Barnett Shale horizontal well at a depth of 6,533 feet through 430 feet of the Marble Falls (Lower Pennsylvanian) formation, a high-resistivity formation. The Sharewell EM technology decoded quality survey, tool face and gamma ray data at bottom and during connections.
  Sharewell officials say its EM technology saves the operator time and money by transmitting data faster than mud-pulse and by providing continuous transmission even while making connections. Unlike traditional mud pulse MWD transmission systems, EM technology does not rely on drilling fluids to transmit pressure pulses to the surface. Because EM systems have no moving parts or fluid restrictions, they are more reliable than conventional mud-pulse tools.
