MWD

During directional drilling operations, data is gathered downhole and transmitted to surface. Measurement-while-drilling (MWD) sensors collect data used to determine basic trajectory parameters such as inclination, direction, and tool-face orientation. These measurements confirm the location of the wellbore and provide the data required to determine what is needed to steer the well to its intended location. Additional downhole sensors collect data regarding drilling conditions (shock and vibration monitoring) and other wellbore data (gamma ray, resistivity, pressure).

​

Once captured downhole, all of this data is converted into binary code and transmitted to surface through the FUSION data transmission technologies. In addition, operational instructions are also transmitted downhole (talk-down) to manage power levels and other tool parameters.

​

Since 2003, Cathedral has been designing, building, and assembling MWD systems to operate in the most demanding drilling environments. Our in-house technology development and manufacturing capability enables Cathedral to adapt our technology for specific applications and project situations.

​

Our approach has been simple and direct—develop an integrated suite of complementary tools and technology to simplify the capture and transmission of data for our customers.

​

Recent enhancements to our proprietary FUSION technology platform have resulted in:

• Superior electromagnetic data transmission capabilities

• The ability to collect and transmit real-time shock and vibration data

• Further strength enhancements of components to improve performance in increasingly difficult conditions
