Advanced Consulting, Inc. provides one of the best MWD services for the directional drilling services industry. Advanced Consulting provide wellbore surveys, mud motor tool face orientation and Complete MWD measurements.

Wellbore Surveys
Surveys are provided by using an accelerometer/magnetometer sensor package to measure the earth's magnetic and gravitational fields. The resulting magnetic and gravitational measurements are used to calculate azimuth (or direction) and inclination that define the trajectory of the wellbore. The drilling angles can then be used to calculate the physical displacement from the rig surface location defining the position of the wellbore below the earth's surface. The resulting surveys allow the operator and directional drilling company to monitor their planned versus actual wellbore path with real-time data and drill the well to the desired target.

Toolface Orientation
Directional drilling involves the use of a positive displacement mud motor with a bent outer housing to deflect a bit along a pre-determined path. The tool-face orientation defines the direction in which the bent housing is pointed. The directional driller uses the real-time tool-face orientation to drill the well in the proper direction (or azimuth) and build the wellbore angle to the proper inclination.

Real-time Data Transmission
All data acquired by the MWD sensor packages is transmitted up hole using positive pressure pulse sound waves that travel from the bottom of the well being drilled to the surface through the fluid column. The transmitted data is decoded on the surface and the digital data is made available to the directional drillers and geologists for real-time interpretation and decision making during the drilling process.

Mud Pulse Retrievable
This system can be utilized to reduce lost in hole risk. In the event the BHA becomes stuck during the drilling process, the retrievable MWD system can be retrieved, saving the customer the cost of replacing the MWD system.
