This project presents learning about basic of Directional drilling and failure of measurement while drilling ( MWD ) tool . This project detail about the MWD tool basic and problems caused in the petroleum industry and its uses. How the directional impact in ONGC . Ongc working on the some number of development wells and gain 99 % will under production . MWD tool has gives the direction of coordinate that EASTING , NORTHING , AZIMUTHAL , INCLINATION , TRUE DEPTH , MEASURED DEPTH . This working under the well details that travelling in signal carry to surface through the mud pulse by binary coding that decoding by computer unit and some of the MWD software that survey the measured of depth of drilling MWD tool have some of part that install to make to Telemetry Channel ,Transmission System , Power Source ,MWD Sensors , Surface Systems . In this main important is Battery , directional sensor , gamma sensor , magnetometer , accelerometers .these makes the depth measured and avoiding of the another well and magnetic components .Directional drilling make the drilling process is more easy that reach the target which are unreachable . Drilling has makes that kick off point that soil has specific viscosity that which turn the direction of drilling in all direction . This project detail about failure about the MWD tool in ONGC that makes the target quite expenditures and time taken projects . The ONGC has solved that problems easily by MWD engineer that effect staff . Some of the problems like CHOKE problem , electrical connected problem , no signal problem . Thus the result on cases study on end of project .
